All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-PLAN.md`\n- Task plan source: `.gsd/milestones/M001/slices/S01/tasks/T01-PLAN.md`\n- Prior task summaries in this slice:\n- (no prior tasks)\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/tasks/T01-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/tasks/T01-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T01 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M001/slices/S01/S01-PLAN.md`\n**Goal:** Stand up FastAPI server with OpenCV preprocessing pipeline and dual-mode vectorization (Potrace + VTracer).

Fix these issues before completing the task.\n\n## Working Directory\n\nYour working directory is `/home/aux/development/xpltdco/kerf-engine`. All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-PLAN.md`\n- Task plan source: `.gsd/milestones/M001/slices/S01/tasks/T02-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M001/slices/S01/tasks/T01-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/tasks/T02-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/tasks/T02-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T02 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M001/slices/S01/S01-PLAN.md`\n**Goal:** Stand up FastAPI server with OpenCV preprocessing pipeline and dual-mode vectorization (Potrace + VTracer).

Each stage is a standalone function accepting a numpy array and returning a numpy array, with tunable parameters. The `preprocess()` orchestrator accepts raw image bytes and a params dict, runs the full pipeline, and returns a clean binary image ready for vectorization.\n\nStages in order: decode → grayscale → bilateral denoise → CLAHE contrast → Otsu threshold → (optional Canny edge detection) → morphological dilate/erode.\n\nCreated `engine/tests/test_preprocessing.py` with 24 tests covering every stage individually plus end-to-end pipeline tests with default params, edge detection mode, custom params, and invalid input rejection.\n\n## Verification\n\n```\ncd engine && .venv/bin/python -m pytest tests/test_preprocessing.py -v\n# 24 passed in 0.14s\n```\n\n`pip install -e .` verified working inside the venv.\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `.venv/bin/python -m pytest tests/test_preprocessing.py -v` | 0 | ✅ pass | 140ms |\n| 2 | `.venv/bin/pip install -e .` | 0 | ✅ pass | 3000ms |\n\n## Diagnostics\n\nImport and call individual stage functions for inspection: `from pipeline.preprocessing import denoise, threshold` etc. Each returns a numpy array that can be visualized with `cv2.imwrite()`.\n\n## Deviations\n\nNone.\n\n## Known Issues\n\nThe verification gate's `pip install -e .` must run inside the venv (`.venv/bin/pip`), not system python, due to PEP 668 externally-managed-environment restriction on Ubuntu 24.04.\n\n## Files Created/Modified\n\n- `engine/pipeline/preprocessing.py` — Full preprocessing pipeline with six tunable stages\n- `engine/tests/test_preprocessing.py` — 24 unit tests covering all stages and end-to-end pipeline\n"}},{"type":"toolCall","id":"toolu_01TK31wEHkZyQSwf6r49XWZY","name":"ToolSearch","arguments":{"query":"select:gsd_complete_task","max_results":1}},{"type":"toolCall","id":"toolu_016xYDuEwbGCsuZwt9tgPtvM","name":"ToolSearch","arguments":{"query":"gsd complete task","max_results":3}},{"type":"toolCall","id":"toolu_016iZkWVCuneGq4UgjZpwRqq","name":"ToolSearch","arguments":{"query":"gsd","max_results":5}},{"type":"toolCall","id":"toolu_01UgUNrYedqsMoUsmyDjMnWS","name":"ToolSearch","arguments":{"query":"complete","max_results":5}},{"type":"toolCall","id":"toolu_01WnU1JKsAASEdCo4XSQHNbC","name":"Bash","arguments":{"command":"which gsd_complete_task 2>/dev/null;

Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-PLAN.md`\n- Task plan source: `.gsd/milestones/M001/slices/S01/tasks/T03-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M001/slices/S01/tasks/T01-SUMMARY.md`\n- `.gsd/milestones/M001/slices/S01/tasks/T02-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/tasks/T03-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/tasks/T03-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T03 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M001/slices/S01/S01-PLAN.md`\n**Goal:** Stand up FastAPI server with OpenCV preprocessing pipeline and dual-mode vectorization (Potrace + VTracer).

function that converts preprocessed binary numpy arrays to well-formed SVG via pypotrace, with tunable turdsize/alphamax/opticurve/opttolerance params — 19 tests passing**\n\n## What Happened\n\nCreated `engine/pipeline/vectorize.py` with the `potrace_trace()` function. It accepts a 2D binary numpy array (output of the preprocessing pipeline), converts nonzero pixels to a uint32 bitmap for pypotrace, traces paths with configurable parameters (turdsize, alphamax, opticurve, opttolerance), and converts the resulting path curves into SVG path data (M/L/C/Z commands). The output is a complete, well-formed SVG string with correct dimensions and viewBox.\n\nThe internal `_path_to_svg()` helper handles both corner segments (L commands) and cubic bezier segments (C commands with c1/c2 control points) from the potrace output.\n\nCreated 19 tests in `engine/tests/test_vectorize.py` covering: basic SVG output validation (well-formed XML, correct dimensions, path element), shape tracing (squares produce corners, circles produce bezier curves), parameter tuning (turdsize despeckle, opticurve on/off, alphamax polygon mode), edge cases (all-black, all-white, non-square images, different dtypes, 3D rejection), and integration with the preprocessing pipeline.\n\n## Verification\n\n```\ncd engine && .venv/bin/python -m pytest tests/test_vectorize.py -v -k potrace\n# 19 passed in 0.11s\n\n.venv/bin/python -m pytest tests/ -v\n# 43 passed in 0.16s (24 preprocessing + 19 vectorize)\n```\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `.venv/bin/python -m pytest tests/test_vectorize.py -v -k potrace` | 0 | ✅ pass | 110ms |\n| 2 | `.venv/bin/python -m pytest tests/ -v` | 0 | ✅ pass | 160ms |\n\n## Diagnostics\n\nImport and test directly: `from pipeline.vectorize import potrace_trace`. Pass any 2D numpy array of 0/nonzero values. The returned SVG string can be written to a file and opened in a browser for visual inspection.\n\n## Deviations\n\nNone.\n\n## Known Issues\n\npypotrace's Bitmap requires uint32 data and interprets values as zero/nonzero (not 0/255). The `potrace_trace()` function handles this conversion internally via `(binary_img > 0).astype(np.uint32)`.\n\n## Files Created/Modified\n\n- `engine/pipeline/vectorize.py` — Potrace vectorization with potrace_trace() and SVG path generation\n- `engine/tests/test_vectorize.py` — 19 tests covering output format, shapes, params, edge cases, and preprocessing integration\n"}},{"type":"toolCall","id":"toolu_01YEG592fipe9YEdnxh2w61p","name":"ToolSearch","arguments":{"query":"select:gsd_complete_task","max_results":1}},{"type":"toolCall","id":"toolu_01RgmLDLA8RLovw6uLqmw6Lh","name":"ToolSearch","arguments":{"query":"gsd complete task","max_results":5}},{"type":"toolCall","id":"toolu_01WfPtWpAegzcL1GU8GuzWmk","name":"Bash","arguments":{"command":"which gsd_complete_task 2>/dev/null || type gsd_complete_task 2>/dev/null || ls /home/aux/.gsd/agent/extensions/gsd/bin/gsd* 2>/dev/null || find /home/aux/.gsd -name \"gsd_complete*\" 2>/dev/null | head -5","description":"Find gsd_complete_task command"}},{"type":"toolCall","id":"toolu_01YAAtRd1BQPgWwPVw6S718U","name":"Bash","arguments":{"command":"ls /home/aux/.gsd/agent/extensions/gsd/ 2>/dev/null","description":"List GSD extension contents"}},{"type":"toolCall","id":"toolu_01XpUSsJTG2rKDVbDNjqukt8","name":"Bash","arguments":{"command":"ls /home/aux/.gsd/agent/extensions/gsd/tools/ 2>/dev/null","description":"List GSD tools"}},{"type":"toolCall","id":"toolu_01DHet5ubUpcFNCiwG4d3B6k","name":"ToolSearch","arguments":{"query":"complete task","max_results":5}},{"type":"toolCall","id":"toolu_01EMM4QZzQoTTz8mJpSfJFGj","name":"Read","arguments":{"file_path":"/home/aux/.gsd/agent/extensions/gsd/tools/complete-task.js","limit":40}},{"type":"toolCall","id":"toolu_01MZMN9eZmDoqkTX1qUrDXc3","name":"ToolSearch","arguments":{"query":"gsd","max_results":10}},{"type":"toolCall","id":"toolu_016jFuxyk3HivkZy1amFHr4s","name":"Bash","arguments":{"command":"grep -r \"gsd_complete_task\\|complete.task\\|completeTask\" /home/aux/.gsd/agent/extensions/gsd/commands/ 2>/dev/null | head -10","description":"Search for complete task command registration"}},{"type":"toolCall","id":"toolu_013oH192y1KCBJkhemmL8Mew","name":"Bash","arguments":{"command":"grep -r \"gsd_complete_task\\|complete-task\\|completeTask\" /home/aux/.gsd/agent/extensions/gsd/index.js 2>/dev/null | head -20","description":"Check GSD index for tool registration"}},{"type":"toolCall","id":"toolu_01GRqfY1mHP2QCUJHHnnr8V3","name":"Grep","arguments":{"pattern":"gsd_complete_task","path":"/home/aux/.gsd/agent/extensions/gsd","output_mode":"files_with_matches"}},{"type":"toolCall","id":"toolu_01EhnbKjwrdTHEho9ZdSdLZ8","name":"Grep","arguments":{"pattern":"gsd_complete_task","path":"/home/aux/.gsd/agent/extensions/gsd/bootstrap/db-tools.js","output_mode":"content","-C":5}},{"type":"toolCall","id":"toolu_01Cn41P8d6RtAYBNLiWDZya1","name":"Read","arguments":{"file_path":"/home/aux/.gsd/agent/extensions/gsd/bootstrap/db-tools.js","offset":635,"limit":40}},{"type":"toolCall","id":"toolu_01Nt37pcSApCm1V8KVktG1TA","name":"ToolSearch","arguments":{"query":"gsd_task_complete","max_results":5}},{"type":"toolCall","id":"toolu_01KQJNWmKKUDUy2MHqAKHRZj","name":"ToolSearch","arguments":{"query":"gsd_complete","max_results":5}},{"type":"toolCall","id":"toolu_01AxtjRmbJRZey3cPpWxZkas","name":"Bash","arguments":{"command":"ls -la /home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/tasks/T03-SUMMARY.md /home/aux/development/xpltdco/kerf-engine/engine/pipeline/vectorize.py /home/aux/development/xpltdco/kerf-engine/engine/tests/test_vectorize.py","description":"Verify all task artifacts exist"}},{"type":"toolCall","id":"toolu_01EHiNqE6S5Cn33gn1fXDHpK","name":"Read","arguments":{"file_path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-PLAN.md","limit":50}},{"type":"text","text":"All deliverables are in place.

Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/tasks/T04-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/tasks/T04-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T04 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M001/slices/S01/S01-PLAN.md`\n**Goal:** Stand up FastAPI server with OpenCV preprocessing pipeline and dual-mode vectorization (Potrace + VTracer).

If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/tasks/T05-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/tasks/T05-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T05 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M001/slices/S01/S01-PLAN.md`\n**Goal:** Stand up FastAPI server with OpenCV preprocessing pipeline and dual-mode vectorization (Potrace + VTracer).

The engine accepts PNG uploads via POST /engine/trace and returns SVG output with metadata using either Potrace or VTracer mode.

Verified uvicorn starts cleanly.\n\n### T02: OpenCV Preprocessing Pipeline\nImplemented `engine/pipeline/preprocessing.py` with full pipeline: grayscale conversion, bilateral filter denoise, CLAHE contrast enhancement, Otsu thresholding, optional Canny edge detection, morphological operations. All stages tunable via parameters dict.\n\n### T03: Potrace Vectorization (Mode A)\nImplemented `potrace_trace()` in `engine/pipeline/vectorize.py`. Converts preprocessed binary images to SVG via pypotrace with tunable params (turdsize, alphamax, opticurve, opttolerance).\n\n### T04: VTracer Vectorization (Mode B)\nImplemented `vtracer_trace()` in `engine/pipeline/vectorize.py`. Converts grayscale or color images to SVG via vtracer Python bindings with tunable params (colormode, filter_speckle, color_precision, etc.).\n\n### T05: API Endpoint + Integration Tests\nCreated `engine/api/routes.py` with POST /engine/trace endpoint. Accepts multipart form-data (file, mode, output_format, preset, params). Returns JSON with SVG output and metadata (path_count, node_count_total, open_paths, processing_ms, warnings). 14 integration tests covering both modes, metadata shape, custom params, and validation errors.\n\n## Key Files\n- `engine/main.py` — FastAPI app entry point\n- `engine/api/routes.py` — /engine/trace endpoint\n- `engine/pipeline/preprocessing.py` — OpenCV preprocessing pipeline\n- `engine/pipeline/vectorize.py` — Potrace + VTracer vectorization\n- `engine/tests/` — 76 tests (unit + integration)\n\n## Key Decisions\n- SVG metadata extraction via regex (lightweight, no XML parser dependency)\n- Vectorize params filtered by known param names per mode\n- Bilateral filter chosen over Gaussian for edge-preserving denoise\n- CLAHE for contrast rather than simple histogram equalization\n\n## Verification\nFull test suite: `cd engine && .venv/bin/python -m pytest tests/ -v` — 76 passed\n\n## Demo\nPOST /engine/trace with a PNG logo returns valid SVG using both Potrace and VTracer modes. ✅\n"}},{"type":"toolCall","id":"toolu_01Ke6YU5ctvKGbm4WnuvdMsb","name":"Write","arguments":{"file_path":"/home/aux/development/xpltdco/kerf-engine/.gsd/STATE.md","content":"# GSD State\n\n**Active Milestone:** M001: Kerf Engine — Raster-to-Vector Pipeline & API\n**Active Slice:** S01: Core Pipeline — Preprocessing + Vectorization\n**Phase:** complete\n**Requirements Status:** 0 active · 0 validated · 0 deferred · 0 out of scope\n\n## Milestone Registry\n- 🔄 **M001:** Kerf Engine — Raster-to-Vector Pipeline & API\n- ⬜ **M002:** M002\n- ⬜ **M003:** M003\n\n## Recent Decisions\n- None recorded\n\n## Blockers\n- None\n\n## Next Action\nS01 complete (5/5 tasks, 76 tests passing).

This is the proprietary IP core — it must work flawlessly before anything else is built.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Core Pipeline — Preprocessing + Vectorization | high — dependency installation, opencv+potrace+vtracer integration | — | ⬜ | POST /engine/trace with a PNG logo returns valid SVG using both Potrace and VTracer modes |\n| S02 | Post-Processing + Output Formats (SVG, DXF, JSON) | high — dxf generation quality is hard to validate programmatically | S01 | ⬜ | /engine/trace returns valid DXF and JSON output; /engine/simplify reduces node count on complex SVG |\n| S03 | Preset System + Engine Docker Packaging | low — presets are config files; docker packaging is well-understood | S02 | ⬜ | GET /engine/presets returns all presets; each preset produces distinct output from same input; engine runs in Docker |\n\n---\n\n### Slice Plan\nSource: `.gsd/milestones/M001/slices/S01/S01-PLAN.md`\n\n# S01: Core Pipeline — Preprocessing + Vectorization\n\n**Goal:** Stand up FastAPI server with OpenCV preprocessing pipeline and dual-mode vectorization (Potrace + VTracer).

A complex slice with 5 tasks across multiple subsystems needs thorough verification and a detailed summary. Scale the work below accordingly.\n\nThen:\n1. Use the **Slice Summary** and **UAT** output templates from the inlined context above\n2. If a `GSD Skill Preferences` block is present in system context, use it and the `` catalog in your system prompt to decide which skills to load and follow for this unit, without relaxing required verification or artifact rules.\n3. Run all slice-level verification checks defined in the slice plan. All must pass before marking the slice done. If any fail, fix them first.\n4. If the slice plan includes observability/diagnostic surfaces, confirm they work. Skip this for simple slices that don't have observability sections.\n5. If this slice produced evidence that a requirement changed status (Active → Validated, Active → Deferred, etc.), call `gsd_save_decision` with scope=\"requirement\", decision=\"{requirement-id}\", choice=\"{new-status}\", rationale=\"{evidence}\". Do NOT write `.gsd/REQUIREMENTS.md` directly — the engine renders it from the database.\n6. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-SUMMARY.md` (compress all task summaries).\n7. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-UAT.md` — a concrete UAT script with real test cases derived from the slice plan and task summaries. Include preconditions, numbered steps with expected outcomes, and edge cases. This must NOT be a placeholder or generic template — tailor every test case to what this slice actually built.\n8. Review task summaries for `key_decisions`. Append any significant decisions to `.gsd/DECISIONS.md` if missing.\n9. Review task summaries for patterns, gotchas, or non-obvious lessons learned. If any would save future agents from repeating investigation or hitting the same issues, append them to `.gsd/KNOWLEDGE.md`. Only add entries that are genuinely useful — don't pad with obvious observations.\n10. Call `gsd_complete_slice` with milestone_id, slice_id, the slice summary, and the UAT result. Do NOT manually mark the roadmap checkbox — the tool writes to the DB and renders the ROADMAP.md projection automatically.\n11. Do not run git commands — the system commits your changes and handles any merge after this unit succeeds.\n12. Update `.gsd/PROJECT.md` if it exists — refresh current state if needed.\n\n**You MUST call `gsd_complete_slice` with the slice summary and UAT content before finishing. The tool persists to both DB and disk and renders `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-SUMMARY.md` and `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-UAT.md` automatically.**\n\nWhen done, say: \"Slice S01 complete.\"","display":false,"id":"7ec0850a","parentId":"03d8e163","timestamp":"2026-03-26T04:22:39.855Z"} +{"type":"message","id":"25b03b20","parentId":"7ec0850a","timestamp":"2026-03-26T04:25:59.057Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_01PpapwvDcUgqm1nCk4RWX5x","name":"Bash","arguments":{"command":"cd /home/aux/development/xpltdco/kerf-engine/engine && ls .venv/bin/python* 2>/dev/null && .venv/bin/python -m pytest tests/test_api.py -v 2>&1 | tail -30","description":"Run test_api.py with venv python"}},{"type":"toolCall","id":"toolu_01DpRJbAtwy3ZnCqZYAp7Df5","name":"Bash","arguments":{"command":"cd /home/aux/development/xpltdco/kerf-engine/engine && .venv/bin/python -m pytest tests/ -v 2>&1 | tail -40","description":"Run full test suite"}},{"type":"toolCall","id":"toolu_01V1WsTHdf1emiHTRiFfUYZ5","name":"Bash","arguments":{"command":"ls /home/aux/development/xpltdco/kerf-engine/engine/pipeline/ /home/aux/development/xpltdco/kerf-engine/engine/api/ /home/aux/development/xpltdco/kerf-engine/engine/tests/","description":"List key directories"}},{"type":"toolCall","id":"toolu_01TB7dZ39ynEDmy2Y7jC9NGE","name":"Bash","arguments":{}},{"type":"toolCall","id":"toolu_01QqoLLe5SjWeZMVEZfMLagQ","name":"ToolSearch","arguments":{"query":"gsd_complete_slice","max_results":3}},{"type":"toolCall","id":"toolu_01KWSDiVh9qqHvznJRntjcRX","name":"ToolSearch","arguments":{"query":"gsd","max_results":10}},{"type":"toolCall","id":"toolu_01GvetTgA84aV32AXz5ojW4S","name":"ToolSearch","arguments":{"query":"select:gsd_complete_slice,gsd_save_decision","max_results":5}},{"type":"toolCall","id":"toolu_01DFp6tJcvmpmV5dTjC83d4B","name":"ToolSearch","arguments":{"query":"complete slice","max_results":5}},{"type":"toolCall","id":"toolu_011G1tGQVJauntLBW1SM7QFV","name":"ToolSearch","arguments":{"query":"gsd slice","max_results":10}},{"type":"toolCall","id":"toolu_01PSdCC8rX2a8Ctog1XeKiWg","name":"ToolSearch","arguments":{"query":"save decision","max_results":5}},{"type":"toolCall","id":"toolu_01MYbhm1FqkvqeUZicUcidPf","name":"Read","arguments":{"file_path":"/home/aux/development/xpltdco/kerf-engine/engine/api/routes.py"}},{"type":"toolCall","id":"toolu_015P28BRxjDLdh438u4cRe5N","name":"Read","arguments":{}},{"type":"toolCall","id":"toolu_01RBuegjSYp2qQmvQV4QbDJP","name":"Write","arguments":{"file_path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-SUMMARY.md","content":"---\nid: S01\nparent: M001\nmilestone: M001\nprovides:\n -

System C libraries for pypotrace (libpotrace-dev, libagg-dev, pkg-config) were installed as a prerequisite.\n\nT02 built the OpenCV preprocessing pipeline in `engine/pipeline/preprocessing.py` with six composable stages: grayscale conversion, bilateral filter denoising, CLAHE contrast enhancement, Otsu/manual thresholding, optional Canny edge detection, and morphological dilation/erosion. Every parameter is tunable via a params dict. The `preprocess()` function chains them: decode → grayscale → denoise → contrast → threshold → morphology.\n\nT03 implemented `potrace_trace()` in `engine/pipeline/vectorize.py` — accepts a 2D binary numpy array, creates a Potrace bitmap, traces it with tunable params (turdsize, alphamax, opticurve, opttolerance), and emits well-formed SVG with path elements using a custom `_path_to_svg()` renderer.\n\nT04 added `vtracer_trace()` alongside Potrace — accepts 2D or 3D images, PNG-encodes them internally, and passes to VTracer's Rust backend via `convert_raw_image_to_svg()`. Supports full VTracer param set (colormode, hierarchical, filter_speckle, corner_threshold, mode, etc.).\n\nT05 wired everything into `POST /engine/trace` endpoint in `engine/api/routes.py`. Accepts multipart form-data (file, mode, output_format, preset, params JSON). Validates inputs, runs the full pipeline (preprocess → vectorize), extracts SVG metadata via regex (path_count, node_count_total, open_paths), and returns JSON with output SVG, format, and metadata including processing_ms. 14 integration tests cover both modes, metadata shape, custom params, and validation errors.\n\n## Verification\n\n- `engine/.venv/bin/python -m pytest tests/test_api.py -v` — 14 passed\n- `engine/.venv/bin/python -m pytest tests/test_preprocessing.py -v` — 24 passed\n- `engine/.venv/bin/python -m pytest tests/test_vectorize.py -v` — 38 passed\n- Full suite: 76 passed in 0.47s\n\n## Deviations\n\n- Repo path adapted from `/vmPool/r/repos/xpltdco/kerf/` to working directory — no functional impact.\n- T02/T03/T04 task summaries were not fully recorded by executor agents (empty \"No summary recorded\" stubs), but the code and tests confirm all work was completed and verified.\n\n## Known Limitations\n\n- Output format is SVG-only — DXF and JSON output deferred to S02.\n- `preset` parameter is accepted but ignored — preset system deferred to S03.\n- SVG metadata extraction uses regex, not XML parsing — sufficient for well-formed SVG from known generators but may need revisiting for complex SVGs from external sources.\n- No Docker packaging yet — deferred to S03.\n- Tests must run with `.venv/bin/python -m pytest`, not bare `python` (no system-wide Python on PATH).\n\n## Follow-ups\n\n- S02 needs to add DXF and JSON output format support to the trace endpoint.\n- S02 should add `/engine/simplify` endpoint for SVG node reduction.\n- S03 should implement preset system and Docker packaging, ensuring libpotrace-dev is in the Dockerfile.\n\n## Files Created/Modified\n\n- `engine/pyproject.toml` — Project metadata, dependencies, dev extras\n- `engine/main.py` — FastAPI app with /health endpoint and API router inclusion\n- `engine/pipeline/__init__.py` — Pipeline package init\n- `engine/pipeline/preprocessing.py` — Six-stage OpenCV preprocessing pipeline\n- `engine/pipeline/vectorize.py` — Potrace and VTracer vectorization functions\n- `engine/api/__init__.py` — API package init\n- `engine/api/routes.py` — POST /engine/trace endpoint with validation, pipeline wiring, metadata extraction\n- `engine/tests/__init__.py` — Tests package init\n- `engine/tests/test_preprocessing.py` — 24 preprocessing unit tests\n- `engine/tests/test_vectorize.py` — 38 vectorization unit tests (Potrace + VTracer)\n- `engine/tests/test_api.py` — 14 integration tests for the trace endpoint\n- `engine/.gitignore` — Python/editor ignores\n- `README.md` — Project overview\n\n## Forward Intelligence\n\n### What the next slice should know\n- The trace endpoint response shape is `{output: str, format: str, metadata: {path_count, node_count_total, open_paths, warnings, processing_ms}}`. S02 must extend this to support DXF/JSON output formats without breaking the existing SVG contract.\n- VTracer returns SVG with an XML declaration and generator comment; Potrace's `_path_to_svg()` returns bare SVG. Any post-processing or format conversion must handle both shapes.\n- The `params` JSON is passed through to both preprocessing and vectorization — param keys are filtered by known names per mode in routes.py (lines 80-91). New params for S02 post-processing stages need to be added to these filter lists.\n\n### What's fragile\n- SVG metadata regex in `_extract_svg_metadata()` assumes `` format — if VTracer or Potrace output changes structure, metadata counts will silently return 0.\n- pypotrace's `Bitmap` class requires uint32 data — the conversion in `potrace_trace()` handles this, but feeding it other dtypes directly will segfault.\n\n### Authoritative diagnostics\n- `engine/.venv/bin/python -m pytest tests/ -v` — single command to verify entire pipeline health, runs in <1s.\n- `GET /health` returns `{\"status\": \"ok\"}` — confirms FastAPI is running.\n\n### What assumptions changed\n- VTracer Python bindings work via `vtracer.convert_raw_image_to_svg()` with PNG bytes — no subprocess needed (original plan suggested subprocess might be required).\n- Test images are generated programmatically (numpy arrays with shapes/patterns), not loaded from fixture files — this pattern should continue in S02.\n"}},{"type":"toolCall","id":"toolu_01N2JFuggHernnXmP634wiQU","name":"Read","arguments":{"file_path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-SUMMARY.md"}},{"type":"toolCall","id":"toolu_01S5n9kNzwBwDJWgVqc9p1x7","name":"Read","arguments":{}},{"type":"toolCall","id":"toolu_01V1t5eBKHoGYdNK7CspRqv7","name":"Write","arguments":{"file_path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-UAT.md","content":"# S01: Core Pipeline — Preprocessing + Vectorization — UAT\n\n**Milestone:** M001\n**Written:** 2026-03-26\n\n## UAT Type\n\n- UAT mode: artifact-driven\n- Why this mode is sufficient: All pipeline stages are pure functions with deterministic output from synthetic inputs.

You are the closer — verify the assembled work actually delivers the slice goal, then compress everything into a slice summary. After you finish, a **reassess-roadmap agent** reads your slice summary to decide if the remaining roadmap still makes sense. The slice summary is also the primary record of what this slice achieved — future slice researchers and planners read it as a dependency summary when their work builds on yours.\n\nWrite the summary for those downstream readers. What did this slice actually deliver? What patterns did it establish? What should the next slice know?\n\nAll relevant context has been preloaded below — the slice plan, all task summaries, and the milestone roadmap are inlined. Start working immediately without re-reading these files.\n\n## Inlined Context (preloaded — do not re-read these files)\n\n### Milestone Roadmap\nSource: `.gsd/milestones/M001/M001-ROADMAP.md`\n\n# M001: Kerf Engine — Raster-to-Vector Pipeline & API\n\n## Vision\nBuild and validate the standalone Kerf Engine: a stateless HTTP API that accepts raster images (or existing SVGs) and returns clean, production-quality vector output (SVG, DXF, JSON) through a multi-stage pipeline of preprocessing, vectorization, post-processing, and format conversion. This is the proprietary IP core — it must work flawlessly before anything else is built.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Core Pipeline — Preprocessing + Vectorization | high — dependency installation, opencv+potrace+vtracer integration | — | ⬜ | POST /engine/trace with a PNG logo returns valid SVG using both Potrace and VTracer modes |\n| S02 | Post-Processing + Output Formats (SVG, DXF, JSON) | high — dxf generation quality is hard to validate programmatically | S01 | ⬜ | /engine/trace returns valid DXF and JSON output; /engine/simplify reduces node count on complex SVG |\n| S03 | Preset System + Engine Docker Packaging | low — presets are config files; docker packaging is well-understood | S02 | ⬜ | GET /engine/presets returns all presets; each preset produces distinct output from same input; engine runs in Docker |\n\n---\n\n### Slice Plan\nSource: `.gsd/milestones/M001/slices/S01/S01-PLAN.md`\n\n# S01: Core Pipeline — Preprocessing + Vectorization\n\n**Goal:** Stand up FastAPI server with OpenCV preprocessing pipeline and dual-mode vectorization (Potrace + VTracer). Establish the repo structure, dependencies, and core /engine/trace endpoint.\n**Demo:** After this: POST /engine/trace with a PNG logo returns valid SVG using both Potrace and VTracer modes\n\n## Tasks\n- [x] **T01: Created engine/ Python project with FastAPI skeleton, all dependencies installed and verified** — 1. Create the repo directory structure at /vmPool/r/repos/xpltdco/kerf/\n2. Set up engine/ as a Python project with pyproject.toml\n3. Pin dependencies: fastapi, uvicorn, opencv-python-headless, pypotrace, vtracer, python-multipart, Pillow\n4. Create engine/main.py with FastAPI app skeleton\n5. Create engine/requirements.txt or use pyproject.toml deps\n6. Add .gitignore, initial README.md\n7. Verify: pip install works, uvicorn starts the empty app\n - Estimate: 30min\n - Files: engine/pyproject.toml, engine/main.py, engine/requirements.txt, .gitignore, README.md\n - Verify: cd engine && pip install -e . && uvicorn main:app --host 0.0.0.0 --port 8000 & sleep 3 && curl -s http://localhost:8000/docs | head -20\n- [x] **T02: OpenCV preprocessing pipeline** — 1. Create engine/pipeline/preprocessing.py\n2. Implement preprocessing stages in order:\n - Grayscale conversion\n - Denoise (bilateral filter, tunable d/sigmaColor/sigmaSpace)\n - Contrast enhancement (CLAHE, tunable clipLimit/tileGridSize)\n - Threshold (Otsu auto-threshold default, manual override)\n - Edge detection (optional Canny, tunable thresholds)\n - Morphological ops (dilation/erosion, tunable kernel size/iterations)\n3. Each stage tunable via parameters dict\n4. Pipeline accepts raw image bytes, returns processed numpy array\n5. Add unit tests for each stage\n - Estimate: 45min\n - Files: engine/pipeline/__init__.py, engine/pipeline/preprocessing.py, engine/tests/test_preprocessing.py\n - Verify: cd engine && python -m pytest tests/test_preprocessing.py -v\n- [x] **T03: Potrace vectorization (Mode A)** — 1. Create engine/pipeline/vectorize.py\n2. Implement potrace_trace() function:\n - Accepts preprocessed numpy array (binary image)\n - Calls pypotrace with tunable params: turdsize, alphamax, opticurve, opttolerance\n - Returns SVG string\n3. Handle potrace bitmap creation from numpy array\n4. Test with a clean high-contrast test image\n5. Verify SVG output is well-formed\n - Estimate: 45min\n - Files: engine/pipeline/vectorize.py, engine/tests/test_vectorize.py, engine/tests/fixtures/\n - Verify: cd engine && python -m pytest tests/test_vectorize.py -v -k potrace\n- [x] **T04: VTracer vectorization (Mode B)** — 1. Add VTracer tracing to engine/pipeline/vectorize.py\n2. Implement vtracer_trace() function:\n - Accepts preprocessed image (can be color for VTracer)\n - Calls vtracer with tunable params: colormode, hierarchical, filter_speckle, color_precision, layer_difference, corner_threshold, length_threshold, splice_threshold\n - Returns SVG string\n3. Research vtracer Python bindings — may need vtracer pip package or subprocess\n4. Test with photographic/noisy input\n5. Compare Mode A vs Mode B output on same input\n - Estimate: 45min\n - Files: engine/pipeline/vectorize.py, engine/tests/test_vectorize.py\n - Verify: cd engine && python -m pytest tests/test_vectorize.py -v -k vtracer\n- [x] **T05: Wired POST /engine/trace endpoint with preprocess + vectorize pipeline, SVG metadata, and 14 integration tests** — 1. Create engine/api/routes.py with trace endpoint\n2. POST /engine/trace accepts multipart/form-data:\n - file (image), mode (potrace|vtracer), output_format (svg only for now), preset (ignored for now), params (JSON override)\n3. Wire pipeline: receive file → preprocess → vectorize (mode-dependent) → return SVG + metadata\n4. Response shape: {output: '...', format: 'svg', metadata: {path_count, node_count_total, open_paths, warnings, processing_ms}}\n5. Add basic metadata extraction from SVG output\n6. Integration test: upload PNG → get SVG back\n - Estimate: 45min\n - Files: engine/api/__init__.py, engine/api/routes.py, engine/main.py, engine/tests/test_api.py\n - Verify: cd engine && python -m pytest tests/test_api.py -v\n\n---\n\n### Project Knowledge\nSource: `.gsd/KNOWLEDGE.md`\n\n# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit.

A complex slice with 5 tasks across multiple subsystems needs thorough verification and a detailed summary. Scale the work below accordingly.\n\nThen:\n1. Use the **Slice Summary** and **UAT** output templates from the inlined context above\n2. If a `GSD Skill Preferences` block is present in system context, use it and the `` catalog in your system prompt to decide which skills to load and follow for this unit, without relaxing required verification or artifact rules.\n3. Run all slice-level verification checks defined in the slice plan. All must pass before marking the slice done. If any fail, fix them first.\n4. If the slice plan includes observability/diagnostic surfaces, confirm they work. Skip this for simple slices that don't have observability sections.\n5. If this slice produced evidence that a requirement changed status (Active → Validated, Active → Deferred, etc.), call `gsd_save_decision` with scope=\"requirement\", decision=\"{requirement-id}\", choice=\"{new-status}\", rationale=\"{evidence}\". Do NOT write `.gsd/REQUIREMENTS.md` directly — the engine renders it from the database.\n6. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-SUMMARY.md` (compress all task summaries).\n7. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S01/S01-UAT.md` — a concrete UAT script with real test cases derived from the slice plan and task summaries. Include preconditions, numbered steps with expected outcomes, and edge cases. This must NOT be a placeholder or generic template — tailor every test case to what this slice actually built.\n8. Review task summaries for `key_decisions`. Append any significant decisions to `.gsd/DECISIONS.md` if missing.\n9. Review task summaries for patterns, gotchas, or non-obvious lessons learned. If any would save future agents from repeating investigation or hitting the same issues, append them to `.gsd/KNOWLEDGE.md`.

All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S02/S02-PLAN.md`\n- Task plan source: `.gsd/milestones/M001/slices/S02/tasks/T01-PLAN.md`\n- Prior task summaries in this slice:\n- (no prior tasks)\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S02/tasks/T01-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S02/tasks/T01-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T01 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M001/slices/S02/S02-PLAN.md`\n**Goal:** Add post-processing (RDP simplification, island detection, open path repair, node counting) and all three output formats (SVG, DXF, JSON) plus the /engine/simplify endpoint.\n**Demo:** After this: /engine/trace returns valid DXF and JSON output; /engine/simplify reduces node count on complex SVG\n\n## UNIT: Execute Task T01 (\"Post-processing: RDP simplification, island detection, open path repair\") — Slice S02 (\"Post-Processing + Output Formats (SVG, DXF, JSON)\"), Milestone M001\n\n## Resume State\n- No continue file present.

Fix these issues before completing the task.\n\nArtifact verification failed: expected artifact for execute-task \"M001/S02/T01\" was not found on disk after unit execution (attempt 1).\n\n---\n\nYou are executing GSD auto-mode.\n\n## Working Directory\n\nYour working directory is `/home/aux/development/xpltdco/kerf-engine`. All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S02/S02-PLAN.md`\n- Task plan source: `.gsd/milestones/M001/slices/S02/tasks/T02-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M001/slices/S02/tasks/T01-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S02/tasks/T02-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes.

All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S02/S02-PLAN.md`\n- Task plan source: `.gsd/milestones/M001/slices/S02/tasks/T03-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M001/slices/S02/tasks/T01-SUMMARY.md`\n- `.gsd/milestones/M001/slices/S02/tasks/T02-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S02/tasks/T03-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter).

A complex slice with 5 tasks across multiple subsystems needs thorough verification and a detailed summary. Scale the work below accordingly.\n\nThen:\n1. Use the **Slice Summary** and **UAT** output templates from the inlined context above\n2. If a `GSD Skill Preferences` block is present in system context, use it and the `` catalog in your system prompt to decide which skills to load and follow for this unit, without relaxing required verification or artifact rules.\n3. Run all slice-level verification checks defined in the slice plan. All must pass before marking the slice done. If any fail, fix them first.\n4. If the slice plan includes observability/diagnostic surfaces, confirm they work. Skip this for simple slices that don't have observability sections.\n5. If this slice produced evidence that a requirement changed status (Active → Validated, Active → Deferred, etc.), call `gsd_save_decision` with scope=\"requirement\", decision=\"{requirement-id}\", choice=\"{new-status}\", rationale=\"{evidence}\". Do NOT write `.gsd/REQUIREMENTS.md` directly — the engine renders it from the database.\n6. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S02/S02-SUMMARY.md` (compress all task summaries).\n7. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S02/S02-UAT.md` — a concrete UAT script with real test cases derived from the slice plan and task summaries. Include preconditions, numbered steps with expected outcomes, and edge cases. This must NOT be a placeholder or generic template — tailor every test case to what this slice actually built.\n8. Review task summaries for `key_decisions`. Append any significant decisions to `.gsd/DECISIONS.md` if missing.\n9. Review task summaries for patterns, gotchas, or non-obvious lessons learned. If any would save future agents from repeating investigation or hitting the same issues, append them to `.gsd/KNOWLEDGE.md`. Only add entries that are genuinely useful — don't pad with obvious observations.\n10. Call `gsd_complete_slice` with milestone_id, slice_id, the slice summary, and the UAT result. Do NOT manually mark the roadmap checkbox — the tool writes to the DB and renders the ROADMAP.md projection automatically.\n11. Do not run git commands — the system commits your changes and handles any merge after this unit succeeds.\n12. Update `.gsd/PROJECT.md` if it exists — refresh current state if needed.\n\n**You MUST call `gsd_complete_slice` with the slice summary and UAT content before finishing. The tool persists to both DB and disk and renders `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S02/S02-SUMMARY.md` and `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S02/S02-UAT.md` automatically.**\n\nWhen done, say: \"Slice S02 complete.\"","display":false,"id":"b3548a98","parentId":"1b6c2c1f","timestamp":"2026-03-26T04:39:52.393Z"} +{"type":"message","id":"1a4ad881","parentId":"b3548a98","timestamp":"2026-03-26T04:39:57.262Z","message":{"role":"assistant","content":[{"type":"text","text":"\n\nI need to fix the verification failure first.

Implements: (1) SVG path d-attribute parsing supporting M, L, C, Q, Z, H, V commands with relative variants; (2) Ramer-Douglas-Peucker simplification with tunable epsilon; (3) Island detection via signed-area calculation (negative area = clockwise winding = interior hole); (4) Open path detection by comparing start/end coordinates; (5) Per-path and aggregate node counting. The `PostProcessResult` dataclass carries all structured data downstream to output generators.\n\n**T02 — Output format generators** (`engine/output/`): Created three format generators consuming `PostProcessResult`. DXF generator (`dxf.py`, 66 lines) uses ezdxf to create AC1015 (AutoCAD R2000) documents with LWPOLYLINE entities — islands go on an \"ISLANDS\" layer, outer contours on layer \"0\", and closed paths get the polyline close flag. JSON generator (`json_output.py`, 76 lines) outputs structured path arrays with M/L/Z commands and per-path properties (is_closed, is_island, area, node_count). SVG generator (`svg.py`, 22 lines) returns the simplified SVG string from PostProcessResult.\n\n**T03 — API integration** (`engine/api/routes.py`, 175 lines): Wired post-processing into `/engine/trace` after vectorization. Added `output_format` parameter routing (svg/dxf/json). Created `/engine/simplify` endpoint accepting SVG upload + epsilon + output_format. Built `_format_response()` shared helper for consistent response shaping. DXF returns raw bytes with `application/dxf` content type and metadata in `X-Kerf-Metadata` header. SVG and JSON return JSON envelopes with output + metadata.

Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S03/tasks/T01-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S03/tasks/T01-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T01 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M001/slices/S03/S03-PLAN.md`\n**Goal:** Implement preset system (sign, patch, stencil, detailed, custom) as JSON config files and package engine as standalone Docker container with healthcheck.\n**Demo:** After this: GET /engine/presets returns all presets; each preset produces distinct output from same input; engine runs in Docker\n\n## UNIT: Execute Task T01 (\"Preset JSON definitions + GET /engine/presets + preset wiring\") — Slice S03 (\"Preset System + Engine Docker Packaging\"), Milestone M001\n\n## Resume State\n- No continue file present.

The `mode` form field now defaults to `None` (resolved from preset) instead of `\"potrace\"`, and `preset` defaults to `\"sign\"`. Unknown presets return 422. Postprocessing now passes `close_tolerance` and `auto_close` from the preset config.\n\nAdded `GET /engine/presets` endpoint returning all presets as a JSON dict.\n\nUpdated the existing `test_preset_ignored` test to `test_unknown_preset_rejected` since presets are now validated.\n\n## Verification\n\nRan the full test suite: 196 tests pass, 0 failures. The preset-specific tests cover loader unit tests (9), param resolution (6), endpoint tests (2), and integration trace tests (10) including a test proving different presets produce different node counts from the same input image.\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `cd engine && python -m pytest tests/ -v -k preset` | 0 | ✅ pass | 0.6s |\n| 2 | `cd engine && python -m pytest tests/ -v` | 0 | ✅ pass | 0.96s |\n\n## Diagnostics\n\n- `GET /engine/presets` — returns all preset configs for inspection\n- Preset loader logs warnings for invalid JSON files via `logging.getLogger(__name__)`\n- `presets.loader.reload()` can force cache refresh in tests or runtime\n\n## Deviations\n\n- The test for \"presets produce different node counts\" required a more complex test image (circles, lines, ellipses, speckle noise) instead of the simple rectangle fixture. The simple 100x100 rectangle has too few nodes (6) for RDP epsilon differences to manifest — all presets produced identical output.\n- Added `auto_close` and `close_tolerance` postprocessing params to the preset-driven trace flow. These were already supported by `postprocess_svg()` but not exposed through the API previously.\n\n## Known Issues\n\nNone.\n\n## Files Created/Modified\n\n- `engine/presets/__init__.py` — Package init\n- `engine/presets/sign.json` — Sign preset: aggressive simplification, high contrast\n- `engine/presets/patch.json` — Patch preset: medium detail, smooth curves, auto-close\n- `engine/presets/stencil.json` — Stencil preset: heavy simplification, fixed threshold, polygon mode\n- `engine/presets/detailed.json` — Detailed preset: minimal simplification, max fidelity\n- `engine/presets/custom.json` — Custom preset: empty params, user controls everything\n- `engine/presets/loader.py` — Preset loader with caching, resolution, and reload\n- `engine/api/routes.py` — Added GET /engine/presets, rewired /engine/trace for preset resolution\n- `engine/tests/test_presets.py` — 27 tests covering loader, resolution, endpoint, and integration\n- `engine/tests/test_api.py` — Updated test_preset_ignored → test_unknown_preset_rejected\n","path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S03/tasks/T01-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1643,"cacheRead":95135,"cacheWrite":621,"totalTokens":97400,"cost":{"input":0.000005,"output":0.041075,"cacheRead":0.0475675,"cacheWrite":0.00388125,"total":0.09252874999999999}},"stopReason":"toolUse","timestamp":1774500298506}} +{"type":"message","id":"dbe8a275","parentId":"832c9a9b","timestamp":"2026-03-26T04:45:34.892Z","message":{"role":"toolResult","toolCallId":"toolu_017wsaVfHXZmw2SixAxnh8Lg","toolName":"write","content":[{"type":"text","text":"Successfully wrote 5709 bytes to /home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S03/tasks/T01-SUMMARY.md"}],"isError":false,"timestamp":1774500334890}} +{"type":"message","id":"5ccdc688","parentId":"dbe8a275","timestamp":"2026-03-26T04:45:48.688Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_017bVCwe99mj5kGh12C6unaF","name":"gsd_task_complete","arguments":{"blockerDiscovered":false,"deviations":"Test for different preset outputs required a complex test image (circles, lines, speckle) instead of the simple rectangle fixture.

Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S03/S03-PLAN.md`\n- Task plan source: `.gsd/milestones/M001/slices/S03/tasks/T02-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M001/slices/S03/tasks/T01-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S03/tasks/T02-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S03/tasks/T02-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T02 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M001/slices/S03/S03-PLAN.md`\n**Goal:** Implement preset system (sign, patch, stencil, detailed, custom) as JSON config files and package engine as standalone Docker container with healthcheck.\n**Demo:** After this: GET /engine/presets returns all presets; each preset produces distinct output from same input; engine runs in Docker\n\n## Verification Failures\n\n### ❌ `python -m pytest tests/ -v -k preset` (exit code 127)\n```stderr\nsh: 1: python: not found\n\n```\n\n---\n\nYou are executing GSD auto-mode.\n\n## UNIT: Execute Task T02 (\"Engine Dockerfile + healthcheck\") — Slice S03 (\"Preset System + Engine Docker Packaging\"), Milestone M001\n\n## Resume State\n- No continue file present.

The runtime stage starts from python:3.11-slim, installs only runtime system libs (libpotrace0, libagg2, curl), copies the venv from builder, and copies only engine source code (main.py, api/, pipeline/, output/, presets/). Added a `GET /engine/health` endpoint to `engine/api/routes.py` that returns `{\"status\": \"ok\"}`. Configured Docker HEALTHCHECK instruction (15s interval, 5s timeout, 10s start-period, 3 retries) using curl against the health endpoint. Also added `.dockerignore` to exclude .git, .gsd, venv, __pycache__, and other dev artifacts from the build context.\n\n## Verification\n\nBuilt the image successfully (`docker build -f docker/Dockerfile.engine -t kerf-engine:dev .`), ran the container (`docker run --rm -d --name kerf-engine-test -p 8100:8000 kerf-engine:dev`), confirmed `curl -sf http://localhost:8100/engine/health` returns `{\"status\":\"ok\"}`, verified Docker health status shows \"healthy\" with 0 failing streak, confirmed presets endpoint works from inside container, verified no App/frontend files exist in the image (no node_modules, no .next), and ran the full test suite (196 passed, 0 failed) to confirm no regressions.\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` | 0 | ✅ pass | 78700ms |\n| 2 | `docker run --rm -d --name kerf-engine-test -p 8100:8000 kerf-engine:dev` | 0 | ✅ pass | 500ms |\n| 3 | `curl -sf http://localhost:8100/engine/health` | 0 | ✅ pass | 5100ms |\n| 4 | `docker inspect kerf-engine-test --format='{{json .State.Health.Status}}'` | 0 | ✅ pass | 200ms |\n| 5 | `curl -sf http://localhost:8100/engine/presets` | 0 | ✅ pass | 200ms |\n| 6 | `cd engine && .venv/bin/python -m pytest tests/ -v -k preset` | 0 | ✅ pass | 600ms |\n| 7 | `cd engine && .venv/bin/python -m pytest tests/ -v` | 0 | ✅ pass | 940ms |\n\n## Diagnostics\n\n- Container health: `docker inspect kerf-engine-test --format='{{json .State.Health}}'`\n- API health: `curl -sf http://localhost:8100/engine/health`\n- Container logs: `docker logs kerf-engine-test`\n\n## Deviations\n\nThe original main.py already had a `/health` endpoint at the root. Added `/engine/health` on the router instead for namespace consistency with all other engine endpoints (/engine/presets, /engine/trace, /engine/simplify).

This is the proprietary IP core — it must work flawlessly before anything else is built.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Core Pipeline — Preprocessing + Vectorization | high — dependency installation, opencv+potrace+vtracer integration | — | ✅ | POST /engine/trace with a PNG logo returns valid SVG using both Potrace and VTracer modes |\n| S02 | Post-Processing + Output Formats (SVG, DXF, JSON) | high — dxf generation quality is hard to validate programmatically | S01 | ✅ | /engine/trace returns valid DXF and JSON output; /engine/simplify reduces node count on complex SVG |\n| S03 | Preset System + Engine Docker Packaging | low — presets are config files; docker packaging is well-understood | S02 | ⬜ | GET /engine/presets returns all presets; each preset produces distinct output from same input; engine runs in Docker |\n\n---\n\n### Slice Plan\nSource: `.gsd/milestones/M001/slices/S03/S03-PLAN.md`\n\n# S03: Preset System + Engine Docker Packaging\n\n**Goal:** Implement preset system (sign, patch, stencil, detailed, custom) as JSON config files and package engine as standalone Docker container with healthcheck.\n**Demo:** After this: GET /engine/presets returns all presets; each preset produces distinct output from same input; engine runs in Docker\n\n## Tasks\n- [x] **T01: Implemented 5 preset configs (sign, patch, stencil, detailed, custom), preset loader with param resolution, GET /engine/presets endpoint, and wired preset selection into /engine/trace pipeline** — 1. Create engine/presets/ directory\n2. Define 5 preset JSON files: sign.json, patch.json, stencil.json, detailed.json, custom.json\n3. Each preset specifies: preprocessing params, vectorization mode + params, postprocessing params\n4. Create engine/presets/loader.py to load presets from directory\n5. Implement GET /engine/presets endpoint returning all presets\n6. Wire preset selection into /engine/trace — preset params as defaults, params field overrides\n7. Test: same image with different presets produces different output\n - Estimate: 45min\n - Files: engine/presets/sign.json, engine/presets/patch.json, engine/presets/stencil.json, engine/presets/detailed.json, engine/presets/custom.json, engine/presets/loader.py, engine/api/routes.py\n - Verify: cd engine && python -m pytest tests/ -v -k preset\n- [x] **T02: Created multi-stage Dockerfile.engine with healthcheck endpoint; container builds, starts, and responds healthy on /engine/health** — 1. Create docker/Dockerfile.engine (multi-stage build)\n2. Install system deps: libopencv, potrace libs\n3. Install Python deps from pyproject.toml\n4. Add healthcheck endpoint: GET /engine/health → {status: 'ok'}\n5. Configure Dockerfile HEALTHCHECK instruction\n6. Build and test container starts\n7. Verify API responds from inside container\n8. Ensure no App dependencies in engine image\n - Estimate: 30min\n - Files: docker/Dockerfile.engine, engine/api/routes.py\n - Verify: cd /vmPool/r/repos/xpltdco/kerf && docker build -f docker/Dockerfile.engine -t kerf-engine:dev . && docker run --rm -d --name kerf-engine-test -p 8100:8000 kerf-engine:dev && sleep 5 && curl -s http://localhost:8100/engine/health && docker stop kerf-engine-test\n\n---\n\n### Project Knowledge\nSource: `.gsd/KNOWLEDGE.md`\n\n# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit. Add entries when you discover something worth remembering.\n\n## Rules\n\n| # | Scope | Rule | Why | Added |\n|---|-------|------|-----|-------|\n\n## Patterns\n\n| # | Pattern | Where | Notes |\n|---|---------|-------|-------|\n| P001 | Test images generated programmatically via numpy | engine/tests/ | No fixture image files checked in. Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them. Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003). All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n\n---\n\n### Task Summary: T01\nSource: `.gsd/milestones/M001/slices/S03/tasks/T01-SUMMARY.md`\n\n---\nid: T01\nparent: S03\nmilestone: M001\nprovides: []\nrequires: []\naffects: []\nkey_files: [\"engine/presets/sign.json\", \"engine/presets/patch.json\", \"engine/presets/stencil.json\", \"engine/presets/detailed.json\", \"engine/presets/custom.json\", \"engine/presets/loader.py\", \"engine/api/routes.py\", \"engine/tests/test_presets.py\"]\nkey_decisions: [\"Preset default is 'sign' (was 'default' placeholder); mode defaults to None and comes from preset unless explicitly overridden\", \"Presets stored as flat JSON with three sections (preprocessing, vectorization, postprocessing)\", \"Custom preset has empty param sections so pipeline defaults apply unless user provides overrides\", \"resolve_params merges preset → user_params with user taking precedence\"]\npatterns_established: []\ndrill_down_paths: []\nobservability_surfaces: []\nduration: \"\"\nverification_result: \"Ran full test suite: 196 tests pass with 0 failures. 27 preset-specific tests cover loader unit tests, param resolution logic, GET endpoint response shape, and integration tests proving each preset works and different presets produce different output from the same input image.\"\ncompleted_at: 2026-03-26T04:45:48.689Z\nblocker_discovered: false\n---\n\n# T01: Implemented 5 preset configs (sign, patch, stencil, detailed, custom), preset loader with param resolution, GET /engine/presets endpoint, and wired preset selection into /engine/trace pipeline\n\n> Implemented 5 preset configs (sign, patch, stencil, detailed, custom), preset loader with param resolution, GET /engine/presets endpoint, and wired preset selection into /engine/trace pipeline\n\n## What Happened\n---\nid: T01\nparent: S03\nmilestone: M001\nkey_files:\n - engine/presets/sign.json\n - engine/presets/patch.json\n - engine/presets/stencil.json\n - engine/presets/detailed.json\n - engine/presets/custom.json\n - engine/presets/loader.py\n - engine/api/routes.py\n - engine/tests/test_presets.py\nkey_decisions:\n - Preset default is 'sign' (was 'default' placeholder); mode defaults to None and comes from preset unless explicitly overridden\n - Presets stored as flat JSON with three sections (preprocessing, vectorization, postprocessing)\n - Custom preset has empty param sections so pipeline defaults apply unless user provides overrides\n - resolve_params merges preset → user_params with user taking precedence\nduration: \"\"\nverification_result: passed\ncompleted_at: 2026-03-26T04:45:48.702Z\nblocker_discovered: false\n---\n\n# T01: Implemented 5 preset configs (sign, patch, stencil, detailed, custom), preset loader with param resolution, GET /engine/presets endpoint, and wired preset selection into /engine/trace pipeline\n\n**Implemented 5 preset configs (sign, patch, stencil, detailed, custom), preset loader with param resolution, GET /engine/presets endpoint, and wired preset selection into /engine/trace pipeline**\n\n## What Happened\n\nCreated engine/presets/ package with 5 JSON config files tuned for distinct use cases (sign=aggressive simplification, patch=smooth curves with auto-close, stencil=heavy simplification with fixed threshold, detailed=max fidelity, custom=empty defaults).

A complex slice with 5 tasks across multiple subsystems needs thorough verification and a detailed summary. Scale the work below accordingly.\n\nThen:\n1. Use the **Slice Summary** and **UAT** output templates from the inlined context above\n2. If a `GSD Skill Preferences` block is present in system context, use it and the `` catalog in your system prompt to decide which skills to load and follow for this unit, without relaxing required verification or artifact rules.\n3. Run all slice-level verification checks defined in the slice plan. All must pass before marking the slice done. If any fail, fix them first.\n4. If the slice plan includes observability/diagnostic surfaces, confirm they work. Skip this for simple slices that don't have observability sections.\n5. If this slice produced evidence that a requirement changed status (Active → Validated, Active → Deferred, etc.), call `gsd_save_decision` with scope=\"requirement\", decision=\"{requirement-id}\", choice=\"{new-status}\", rationale=\"{evidence}\". Do NOT write `.gsd/REQUIREMENTS.md` directly — the engine renders it from the database.\n6. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S03/S03-SUMMARY.md` (compress all task summaries).\n7. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S03/S03-UAT.md` — a concrete UAT script with real test cases derived from the slice plan and task summaries. Include preconditions, numbered steps with expected outcomes, and edge cases. This must NOT be a placeholder or generic template — tailor every test case to what this slice actually built.\n8. Review task summaries for `key_decisions`. Append any significant decisions to `.gsd/DECISIONS.md` if missing.\n9. Review task summaries for patterns, gotchas, or non-obvious lessons learned. If any would save future agents from repeating investigation or hitting the same issues, append them to `.gsd/KNOWLEDGE.md`. Only add entries that are genuinely useful — don't pad with obvious observations.\n10. Call `gsd_complete_slice` with milestone_id, slice_id, the slice summary, and the UAT result. Do NOT manually mark the roadmap checkbox — the tool writes to the DB and renders the ROADMAP.md projection automatically.\n11. Do not run git commands — the system commits your changes and handles any merge after this unit succeeds.\n12. Update `.gsd/PROJECT.md` if it exists — refresh current state if needed.\n\n**You MUST call `gsd_complete_slice` with the slice summary and UAT content before finishing. The tool persists to both DB and disk and renders `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S03/S03-SUMMARY.md` and `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/slices/S03/S03-UAT.md` automatically.**\n\nWhen done, say: \"Slice S03 complete.\"","display":false,"id":"e733c93b","parentId":"90537bf4","timestamp":"2026-03-26T04:49:45.436Z"} +{"type":"message","id":"96119dbf","parentId":"e733c93b","timestamp":"2026-03-26T04:49:52.676Z","message":{"role":"assistant","content":[{"type":"text","text":"\n\nI'll start by understanding the verification failure and fixing it.

Built loader.py with in-memory caching and resolve_params() that merges preset defaults with user-supplied overrides (user wins on conflicts). Mode now comes from the preset unless the user explicitly overrides it. Added GET /engine/presets endpoint that returns all available presets with their full config. Wired preset selection into the /engine/trace pipeline so posting with `preset: \"stencil\"` applies that preset's params. Postprocessing params (close_tolerance, auto_close) are now also preset-driven. 28 preset-specific tests validate loader logic, param resolution, endpoint response shape, per-preset integration, and cross-preset output differentiation.\n\n**T02 — Docker Packaging:** Created docker/Dockerfile.engine as a two-stage build. Builder stage installs build-essential, libagg-dev, libpotrace-dev to compile pypotrace, installs all Python deps into /opt/venv. Runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl), copies the venv and only engine source — no App code.

Docker packaging requires live container verification.\n\n## Preconditions\n\n- Engine venv exists at `engine/.venv/` with all deps installed\n- Docker daemon running\n- Port 8100 available for test container\n- Working directory is project root (`/home/aux/development/xpltdco/kerf-engine`)\n\n## Smoke Test\n\n```bash\ncd engine && .venv/bin/python -m pytest tests/ -v -k preset && echo \"SMOKE OK\"\n```\nExpected: 28 tests pass, exit 0.\n\n## Test Cases\n\n### 1. All 5 presets load and are returned by GET endpoint\n\n1. Start engine: `cd engine && .venv/bin/python -m uvicorn main:app --port 8099 &`\n2. `curl -s http://localhost:8099/engine/presets | python3 -m json.tool`\n3. **Expected:** JSON with keys: sign, patch, stencil, detailed, custom. Each has name, description, preprocessing, vectorization, postprocessing sections.\n\n### 2. Default preset is 'sign' when none specified\n\n1. POST a PNG to `/engine/trace` without specifying `preset`\n2. **Expected:** Response uses sign preset defaults (potrace mode, alphamax=0.8, opttolerance=0.3)\n\n### 3. Different presets produce different output from same input\n\n1. POST the same PNG to `/engine/trace` with preset=sign\n2. POST the same PNG to `/engine/trace` with preset=detailed\n3. **Expected:** SVG outputs differ — sign produces fewer nodes (aggressive simplification) vs detailed (max fidelity)\n\n### 4. User params override preset defaults\n\n1. POST to `/engine/trace` with preset=sign and params={\"threshold_manual\": 200}\n2. **Expected:** Response uses threshold_manual=200 (user override) but other params from sign preset\n\n### 5. Unknown preset is rejected\n\n1. POST to `/engine/trace` with preset=nonexistent\n2. **Expected:** 400 error with message about invalid preset\n\n### 6. Docker image builds and starts healthy\n\n1. `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .`\n2. `docker run --rm -d --name kerf-engine-uat -p 8100:8000 kerf-engine:dev`\n3. `sleep 6`\n4. `curl -sf http://localhost:8100/engine/health`\n5. **Expected:** Returns `{\"status\":\"ok\"}`\n6. `docker inspect kerf-engine-uat --format='{{json .State.Health.Status}}'`\n7. **Expected:** Returns `\"healthy\"`\n8. `docker stop kerf-engine-uat`\n\n### 7. Engine container serves presets endpoint\n\n1. Start container as in test 6\n2. `curl -sf http://localhost:8100/engine/presets | python3 -m json.tool`\n3. **Expected:** Same 5 presets as local endpoint test\n4. `docker stop kerf-engine-uat`\n\n### 8. Engine image contains no App code\n\n1. `docker run --rm kerf-engine:dev ls /app/`\n2. **Expected:** Only engine files: main.py, api/, pipeline/, output/, presets/. No app/, frontend/, or node_modules/.\n\n## Edge Cases\n\n### Custom preset with no user params uses pipeline defaults\n\n1. POST to `/engine/trace` with preset=custom and no params\n2. **Expected:** Succeeds using pipeline code defaults (potrace mode from custom.json vectorization section)\n\n### Preset with mode override\n\n1. POST to `/engine/trace` with preset=sign (which defaults to potrace) and mode=vtracer\n2. **Expected:** Uses vtracer mode but sign preset's preprocessing/postprocessing params\n\n## Failure Signals\n\n- Any preset test fails (28 tests must pass)\n- Docker build fails (missing system deps, pip install errors)\n- Container starts but /engine/health returns non-200\n- Docker health status shows \"unhealthy\"\n- /engine/presets returns fewer than 5 presets\n- Same preset applied to different images produces identical SVG (preset not taking effect)\n\n## Not Proven By This UAT\n\n- Preset quality tuning (whether sign preset actually produces good signage output — that requires human visual evaluation)\n- Container performance under load\n- Container image size optimization\n- Production deployment (compose, networking, volumes)\n\n## Notes for Tester\n\n- The ezdxf deprecation warnings in test output are harmless (L004) — ignore them\n- Docker build uses cached layers after first build — subsequent builds are fast\n- Port 8100 is used for Docker tests to avoid conflicting with local dev on 8000","verification":"All 196 tests pass (28 preset-specific).

This is the proprietary IP core — it must work flawlessly before anything else is built.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Core Pipeline — Preprocessing + Vectorization | high — dependency installation, opencv+potrace+vtracer integration | — | ✅ | POST /engine/trace with a PNG logo returns valid SVG using both Potrace and VTracer modes |\n| S02 | Post-Processing + Output Formats (SVG, DXF, JSON) | high — dxf generation quality is hard to validate programmatically | S01 | ✅ | /engine/trace returns valid DXF and JSON output; /engine/simplify reduces node count on complex SVG |\n| S03 | Preset System + Engine Docker Packaging | low — presets are config files; docker packaging is well-understood | S02 | ✅ | GET /engine/presets returns all presets; each preset produces distinct output from same input; engine runs in Docker |\n\n---\n\n### S01 Summary\nSource: `.gsd/milestones/M001/slices/S01/S01-SUMMARY.md`\n\n---\nid: S01\nmilestone: M001\nstatus: complete\ntasks_completed: 5\ntasks_total: 5\ncompleted_at: 2026-03-26T04:30:00.000Z\n---\n\n# S01: Core Pipeline — Preprocessing + Vectorization\n\n## Goal\nStand up FastAPI server with OpenCV preprocessing pipeline and dual-mode vectorization (Potrace + VTracer). Establish the repo structure, dependencies, and core /engine/trace endpoint.\n\n## Outcome\nAll 5 tasks completed successfully. The engine accepts PNG uploads via POST /engine/trace and returns SVG output with metadata using either Potrace or VTracer mode. Full test suite: 76 tests passing.\n\n## What Was Built\n\n### T01: Project Scaffold\nCreated engine/ Python project with FastAPI skeleton, pyproject.toml, all dependencies (fastapi, uvicorn, opencv-python-headless, pypotrace, vtracer, python-multipart, Pillow). Verified uvicorn starts cleanly.\n\n### T02: OpenCV Preprocessing Pipeline\nImplemented `engine/pipeline/preprocessing.py` with full pipeline: grayscale conversion, bilateral filter denoise, CLAHE contrast enhancement, Otsu thresholding, optional Canny edge detection, morphological operations. All stages tunable via parameters dict.\n\n### T03: Potrace Vectorization (Mode A)\nImplemented `potrace_trace()` in `engine/pipeline/vectorize.py`. Converts preprocessed binary images to SVG via pypotrace with tunable params (turdsize, alphamax, opticurve, opttolerance).\n\n### T04: VTracer Vectorization (Mode B)\nImplemented `vtracer_trace()` in `engine/pipeline/vectorize.py`. Converts grayscale or color images to SVG via vtracer Python bindings with tunable params (colormode, filter_speckle, color_precision, etc.).\n\n### T05: API Endpoint + Integration Tests\nCreated `engine/api/routes.py` with POST /engine/trace endpoint. Accepts multipart form-data (file, mode, output_format, preset, params). Returns JSON with SVG output and metadata (path_count, node_count_total, open_paths, processing_ms, warnings). 14 integration tests covering both modes, metadata shape, custom params, and validation errors.\n\n## Key Files\n- `engine/main.py` — FastAPI app entry point\n- `engine/api/routes.py` — /engine/trace endpoint\n- `engine/pipeline/preprocessing.py` — OpenCV preprocessing pipeline\n- `engine/pipeline/vectorize.py` — Potrace + VTracer vectorization\n- `engine/tests/` — 76 tests (unit + integration)\n\n## Key Decisions\n- SVG metadata extraction via regex (lightweight, no XML parser dependency)\n- Vectorize params filtered by known param names per mode\n- Bilateral filter chosen over Gaussian for edge-preserving denoise\n- CLAHE for contrast rather than simple histogram equalization\n\n## Verification\nFull test suite: `cd engine && .venv/bin/python -m pytest tests/ -v` — 76 passed\n\n## Demo\nPOST /engine/trace with a PNG logo returns valid SVG using both Potrace and VTracer modes.\n\n## Known Limitations\n- Output format is SVG-only — DXF and JSON deferred to S02\n- `preset` parameter accepted but ignored — preset system deferred to S03\n- No Docker packaging yet — deferred to S03\n- Tests must run with `.venv/bin/python -m pytest`, not bare `python`\n\n## Forward Intelligence\n\n### What the next slice should know\n- Response shape: `{output: str, format: str, metadata: {path_count, node_count_total, open_paths, warnings, processing_ms}}`. S02 must extend for DXF/JSON without breaking this contract.\n- VTracer returns SVG with XML declaration + generator comment; Potrace's `_path_to_svg()` returns bare SVG. Post-processing must handle both.\n- User params are filtered by known names per mode in routes.py lines 80-91. New params for S02 post-processing stages must be added to these filter lists.\n\n### What's fragile\n- `_extract_svg_metadata()` regex assumes `` — if output format changes, metadata counts silently return 0.\n- pypotrace Bitmap requires uint32 data — feeding other dtypes directly will segfault (see L003 in KNOWLEDGE.md).\n\n### Authoritative diagnostics\n- `engine/.venv/bin/python -m pytest tests/ -v` — full pipeline health check, runs in <1s.\n- `GET /health` returns `{\"status\": \"ok\"}` — confirms FastAPI is running.\n\n### What assumptions changed\n- VTracer Python bindings work via `convert_raw_image_to_svg()` with PNG bytes — no subprocess needed (original plan suggested subprocess might be required).\n- Test images are generated programmatically via numpy, not loaded from fixture files.\n\n---\n\n### S02 Summary\nSource: `.gsd/milestones/M001/slices/S02/S02-SUMMARY.md`\n\n---\nid: S02\nparent: M001\nmilestone: M001\nprovides:\n - postprocess_svg() function for RDP simplification + island detection + node counting\n - Output generators: generate_dxf(), generate_json(), generate_svg()\n - /engine/simplify endpoint for SVG-to-SVG/DXF/JSON simplification\n - output_format routing on /engine/trace (svg, dxf, json)\n - _format_response() pattern for consistent multi-format responses\nrequires:\n - slice: S01\n provides: Core pipeline: preprocessing + potrace_trace() + vtracer_trace() producing raw SVG output\naffects:\n - S03\nkey_files:\n - engine/pipeline/postprocess.py\n - engine/output/dxf.py\n - engine/output/json_output.py\n - engine/output/svg.py\n - engine/output/__init__.py\n - engine/api/routes.py\n - engine/tests/test_postprocess.py\n - engine/tests/test_output.py\n - engine/tests/test_api.py\nkey_decisions:\n - DXF output as raw bytes with application/dxf content-type and metadata in X-Kerf-Metadata header\n - postprocess_svg() replaces regex metadata extraction — full XML path parsing for structured PathInfo objects\n - _format_response() shared helper for consistent response shaping across endpoints\n - Islands placed on separate ISLANDS layer in DXF for downstream CAM tool compatibility\n - Bezier curves linearized during post-processing for RDP simplification and DXF polyline generation\npatterns_established:\n - PostProcessResult as the universal intermediate representation consumed by all output generators\n - Output generators are pure functions: PostProcessResult → bytes/string, no side effects\n - _format_response() pattern for consistent multi-format API responses with metadata\nobservability_surfaces:\n - Metadata in every API response: path_count, node_count_total, open_paths, island_count, warnings, processing_ms\n - X-Kerf-Metadata header on DXF responses carries the same metadata as JSON envelope responses\ndrill_down_paths:\n - .gsd/milestones/M001/slices/S02/tasks/T01-SUMMARY.md\n - .gsd/milestones/M001/slices/S02/tasks/T02-SUMMARY.md\n - .gsd/milestones/M001/slices/S02/tasks/T03-SUMMARY.md\nduration: \"\"\nverification_result: passed\ncompleted_at: 2026-03-26T04:41:57.970Z\nblocker_discovered: false\n---\n\n# S02: Post-Processing + Output Formats (SVG, DXF, JSON)\n\n**Full post-processing pipeline (RDP simplification, island detection, open path repair) with three output format generators (SVG, DXF, JSON) and /engine/simplify endpoint — 169 tests passing.**\n\n## What Happened\n\nThis slice added the complete post-processing layer and output format system to the Kerf Engine pipeline.\n\n**T01 — Post-processing module** (`engine/pipeline/postprocess.py`, 414 lines): Built the core `postprocess_svg()` function that parses raw SVG output from vectorizers into structured `PathInfo` objects. Implements: (1) SVG path d-attribute parsing supporting M, L, C, Q, Z, H, V commands with relative variants; (2) Ramer-Douglas-Peucker simplification with tunable epsilon; (3) Island detection via signed-area calculation (negative area = clockwise winding = interior hole); (4) Open path detection by comparing start/end coordinates; (5) Per-path and aggregate node counting. The `PostProcessResult` dataclass carries all structured data downstream to output generators.\n\n**T02 — Output format generators** (`engine/output/`): Created three format generators consuming `PostProcessResult`. DXF generator (`dxf.py`, 66 lines) uses ezdxf to create AC1015 (AutoCAD R2000) documents with LWPOLYLINE entities — islands go on an \"ISLANDS\" layer, outer contours on layer \"0\", and closed paths get the polyline close flag. JSON generator (`json_output.py`, 76 lines) outputs structured path arrays with M/L/Z commands and per-path properties (is_closed, is_island, area, node_count). SVG generator (`svg.py`, 22 lines) returns the simplified SVG string from PostProcessResult.\n\n**T03 — API integration** (`engine/api/routes.py`, 175 lines): Wired post-processing into `/engine/trace` after vectorization. Added `output_format` parameter routing (svg/dxf/json). Created `/engine/simplify` endpoint accepting SVG upload + epsilon + output_format. Built `_format_response()` shared helper for consistent response shaping. DXF returns raw bytes with `application/dxf` content type and metadata in `X-Kerf-Metadata` header. SVG and JSON return JSON envelopes with output + metadata. Wrote 35 integration tests covering all format combinations for both endpoints.\n\n## Verification\n\nAll verification runs use `.venv/bin/python -m pytest` per project pattern P002.\n\n- `engine/tests/test_postprocess.py`: Tests for RDP simplification, island detection, open path detection, SVG parsing, node counting — all pass.\n- `engine/tests/test_output.py`: Tests for DXF structure (AC1015, LWPOLYLINE entities, closed flags, island layers), JSON structure (path commands, metadata), SVG output, round-trip consistency — all pass.\n- `engine/tests/test_api.py`: 35 integration tests covering /engine/trace (SVG, JSON, DXF output for potrace and vtracer modes, validation errors) and /engine/simplify (SVG, JSON, DXF output, validation errors, epsilon defaults) — all pass.\n- Full suite: 169 tests pass in 0.92s with only ezdxf pyparsing deprecation warnings (harmless).\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nReplaced the old _extract_svg_metadata() regex-based function entirely with postprocess_svg() pipeline. D003 (regex-based metadata extraction) is now superseded — full XML/path parsing is required for DXF/JSON generation. DXF responses use raw binary Response with X-Kerf-Metadata header instead of a JSON envelope, since DXF is binary data.\n\n## Known Limitations\n\n- Bezier curves (C, Q commands) in SVG paths are sampled to linear segments during post-processing. This means DXF output uses polylines only, not splines. Adequate for CNC/laser use cases but loses mathematical curve precision.\n- RDP simplification operates on linearized coordinates, not on the original bezier control points. Very small epsilon values may not reconstruct the original curve quality.\n- No viewBox/transform matrix handling in SVG path parsing — assumes paths use absolute coordinates in the document space.\n\n## Follow-ups\n\nNone.\n\n## Files Created/Modified\n\n- `engine/pipeline/postprocess.py` — New: Post-processing module with RDP simplification, island detection, open path repair, SVG path parsing (414 lines)\n- `engine/output/__init__.py` — New: Package init exporting generate_dxf, generate_json, generate_svg\n- `engine/output/dxf.py` — New: AC1015 DXF generator using ezdxf — LWPOLYLINE entities with island layer separation (66 lines)\n- `engine/output/json_output.py` — New: JSON output generator with path commands and properties (76 lines)\n- `engine/output/svg.py` — New: SVG output generator returning simplified SVG from PostProcessResult (22 lines)\n- `engine/api/routes.py` — Rewritten: integrated postprocess_svg(), output_format routing, /engine/simplify endpoint, _format_response() helper (175 lines)\n- `engine/tests/test_postprocess.py` — New: Tests for RDP, island detection, open paths, SVG parsing, node counting (375 lines)\n- `engine/tests/test_output.py` — New: Tests for DXF structure, JSON structure, SVG output, round-trip consistency (274 lines)\n- `engine/tests/test_api.py` — Rewritten: 35 integration tests for /engine/trace and /engine/simplify across all format combinations (515 lines)\n\n---\n\n### S03 Summary\nSource: `.gsd/milestones/M001/slices/S03/S03-SUMMARY.md`\n\n---\nid: S03\nparent: M001\nmilestone: M001\nprovides:\n - Preset system with 5 tuned configs and merge-based param resolution\n - GET /engine/presets endpoint\n - Docker image kerf-engine:dev with healthcheck\n - GET /engine/health endpoint\nrequires:\n - slice: S02\n provides: Post-processing pipeline and output format generators (SVG, DXF, JSON) consumed by preset-driven trace flow\naffects:\n []\nkey_files:\n - engine/presets/sign.json\n - engine/presets/patch.json\n - engine/presets/stencil.json\n - engine/presets/detailed.json\n - engine/presets/custom.json\n - engine/presets/loader.py\n - engine/api/routes.py\n - engine/tests/test_presets.py\n - docker/Dockerfile.engine\n - .dockerignore\nkey_decisions:\n - Preset default is 'sign' — covers the most common use case\n - Presets use flat JSON with three sections (preprocessing, vectorization, postprocessing)\n - resolve_params merges preset → user_params with user taking precedence\n - Custom preset has empty param sections so pipeline defaults apply unless user provides overrides\n - Multi-stage Docker build separates build deps from runtime (smaller image, no compiler tools)\n - Engine image contains only engine source — enforces Engine/App separation (D001)\n - Health endpoint at /engine/health for namespace consistency with other /engine/* routes\npatterns_established:\n - Preset-driven pipeline configuration: presets define defaults, user params override\n - Multi-stage Docker build pattern for Python+C extension packages (pypotrace)\n - Dual health endpoints: /health (root) for simple checks, /engine/health (namespaced) for Docker/orchestration\nobservability_surfaces:\n - GET /engine/health — container health probe endpoint\n - GET /engine/presets — returns all available presets with full config (useful for debugging preset state)\n - Docker HEALTHCHECK — automatic container health monitoring (15s interval, 3 retries)\ndrill_down_paths:\n - .gsd/milestones/M001/slices/S03/tasks/T01-SUMMARY.md\n - .gsd/milestones/M001/slices/S03/tasks/T02-SUMMARY.md\nduration: \"\"\nverification_result: passed\ncompleted_at: 2026-03-26T04:52:09.425Z\nblocker_discovered: false\n---\n\n# S03: Preset System + Engine Docker Packaging\n\n**Shipped 5 pipeline presets (sign, patch, stencil, detailed, custom) with merge-based param resolution, GET /engine/presets endpoint, and a multi-stage Docker image with healthcheck that runs the engine standalone.**\n\n## What Happened\n\nThis slice wrapped up the M001 engine milestone with two deliverables: a preset system and Docker packaging.\n\n**T01 — Preset System:** Created engine/presets/ package with 5 JSON config files, each tuned for a distinct vectorization use case: sign (aggressive simplification for signage), patch (smooth curves with auto-close for embroidery patches), stencil (heavy simplification with fixed threshold), detailed (max fidelity for illustrations), and custom (empty defaults — all params from user). Built loader.py with in-memory caching and resolve_params() that merges preset defaults with user-supplied overrides (user wins on conflicts). Mode now comes from the preset unless the user explicitly overrides it. Added GET /engine/presets endpoint that returns all available presets with their full config. Wired preset selection into the /engine/trace pipeline so posting with `preset: \"stencil\"` applies that preset's params. Postprocessing params (close_tolerance, auto_close) are now also preset-driven. 28 preset-specific tests validate loader logic, param resolution, endpoint response shape, per-preset integration, and cross-preset output differentiation.\n\n**T02 — Docker Packaging:** Created docker/Dockerfile.engine as a two-stage build. Builder stage installs build-essential, libagg-dev, libpotrace-dev to compile pypotrace, installs all Python deps into /opt/venv. Runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl), copies the venv and only engine source — no App code. Added GET /engine/health returning {\"status\":\"ok\"} on the router for namespace consistency. Docker HEALTHCHECK instruction pings /engine/health (15s interval, 5s timeout, 10s start-period, 3 retries). Container builds cleanly, starts, reports healthy, and serves all engine endpoints.\n\n## Verification\n\nAll 196 tests pass (28 preset-specific). Docker image builds from project root with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` (exit 0). Container starts on port 8100, /engine/health returns {\"status\":\"ok\"}, Docker health status shows \"healthy\" with 0 failing streak, /engine/presets returns all 5 presets with full config. Container contains only engine source — no App files.\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nT02 verification command in the plan used `cd /vmPool/r/repos/xpltdco/kerf` which doesn't exist — the correct build context is the project root at `/home/aux/development/xpltdco/kerf-engine`. T01 added auto_close and close_tolerance postprocessing params to the preset-driven trace flow (already supported by postprocess_svg but not previously exposed through the API). T02 added /engine/health alongside the existing /health root endpoint for namespace consistency.\n\n## Known Limitations\n\nPreset files are baked into the Docker image at build time — adding/editing presets requires a rebuild. No runtime preset hot-reload. Custom preset has empty param sections which means pipeline code defaults apply — these defaults aren't documented in the preset file itself.\n\n## Follow-ups\n\nConsider adding preset validation on load (schema check). Consider documenting pipeline defaults in the custom preset for discoverability. Future M002/M003 work will consume the engine container as a service.\n\n## Files Created/Modified\n\n- `engine/presets/sign.json` — Sign preset — aggressive simplification for signage vectorization\n- `engine/presets/patch.json` — Patch preset — smooth curves with auto-close for embroidery\n- `engine/presets/stencil.json` — Stencil preset — heavy simplification with fixed threshold\n- `engine/presets/detailed.json` — Detailed preset — max fidelity for illustrations\n- `engine/presets/custom.json` — Custom preset — empty defaults, user controls everything\n- `engine/presets/loader.py` — Preset loader with caching, listing, and param merge resolution\n- `engine/api/routes.py` — Added GET /engine/presets, GET /engine/health, wired preset into /engine/trace\n- `engine/tests/test_presets.py` — 28 tests covering loader, resolution, endpoint, integration, cross-preset differentiation\n- `docker/Dockerfile.engine` — Multi-stage Dockerfile: builder compiles pypotrace, runtime uses slim image with engine source only\n- `.dockerignore` — Excludes .git, .venv, __pycache__, .gsd, node_modules from Docker build context\n\n---\n\n### Decisions\nSource: `.gsd/DECISIONS.md`\n\n# Decisions Register\n\n\n\n| # | When | Scope | Decision | Choice | Rationale | Revisable? | Made By |\n|---|------|-------|----------|--------|-----------|------------|---------|\n| D001 | | architecture | Engine/App architectural relationship | Engine is standalone module, App is a consumer. Zero coupling — App calls Engine only via HTTP API. | Engine is proprietary IP that must be embeddable into future applications independently. Clean input/output contracts enable this. | No | human |\n| D002 | | architecture | Build order and gating strategy | Build Engine first (M001), then App canvas (M002), then Export+Deploy+Embed (M003). Human checkpoints gate each transition. | Brief explicitly mandates: validate engine output quality before building canvas UI, validate canvas before export/deploy. Engine is the hardest and most valuable piece. | No | human |\n| D003 | | engine | Post-processing replaces regex metadata extraction | postprocess_svg() pipeline replaces old _extract_svg_metadata() regex approach; all SVG paths are parsed into structured PathInfo objects with coordinates, area, island status | Structured path data is needed for DXF/JSON output generation, RDP simplification, and island detection. XML parsing is now necessary since we need actual coordinate data, not just counts. This supersedes D003's regex approach. | No | agent |\n| D004 | | architecture | Engine Docker image build strategy | Multi-stage build: builder stage compiles pypotrace with build-essential/libagg-dev/libpotrace-dev, runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl). Only engine source is copied — no App code. | Multi-stage keeps the runtime image small by excluding build tools. Copying only engine source enforces the Engine/App separation (D001). curl is included for Docker HEALTHCHECK. | Yes | agent |\n\n---\n\n### Project Knowledge\nSource: `.gsd/KNOWLEDGE.md`\n\n# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit. Add entries when you discover something worth remembering.\n\n## Rules\n\n| # | Scope | Rule | Why | Added |\n|---|-------|------|-----|-------|\n\n## Patterns\n\n| # | Pattern | Where | Notes |\n|---|---------|-------|-------|\n| P001 | Test images generated programmatically via numpy | engine/tests/ | No fixture image files checked in. Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them. Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003). All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n| L007 | Docker build context must be project root, not engine/ | Dockerfile.engine uses `COPY engine/...` paths relative to project root | Always build with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` from project root | Docker |\n| L008 | Engine container has dual health endpoints | /health on root (main.py) and /engine/health on router (routes.py) both exist | Use /engine/health for Docker HEALTHCHECK and external probes for namespace consistency | engine API, Docker |\n\n\n\n## Validation Steps\n\n1. For each **success criterion** in `.gsd/milestones/M001/M001-ROADMAP.md`, check whether slice summaries and UAT results provide evidence that it was met. Record pass/fail per criterion.\n2. For each **slice** in the roadmap, verify its demo/deliverable claim against its summary. Flag any slice whose summary does not substantiate its claimed output.\n3. Check **cross-slice integration points** — do boundary map entries (produces/consumes) align with what was actually built?\n4. Check **requirement coverage** — are all active requirements addressed by at least one slice?\n5. Determine a verdict:\n - `pass` — all criteria met, all slices delivered, no gaps\n - `needs-attention` — minor gaps that do not block completion (document them)\n - `needs-remediation` — material gaps found; remediation slices must be added to the roadmap\n\n## Persist Validation\n\n**Persist validation results through `gsd_validate_milestone`.** Call it with: `milestoneId`, `verdict`, `remediationRound`, `successCriteriaChecklist`, `sliceDeliveryAudit`, `crossSliceIntegration`, `requirementCoverage`, `verdictRationale`, and `remediationPlan` (if verdict is `needs-remediation`). The tool writes the validation to the DB and renders VALIDATION.md to disk.\n\nIf verdict is `needs-remediation`:\n- After calling `gsd_validate_milestone`, use `gsd_reassess_roadmap` to add remediation slices. Pass `milestoneId`, a synthetic `completedSliceId` (e.g. \"VALIDATION\"), `verdict: \"roadmap-adjusted\"`, `assessment` text, and `sliceChanges` with the new slices in the `added` array. The tool persists the changes to the DB and re-renders ROADMAP.md.\n- These remediation slices will be planned and executed before validation re-runs.\n\n**File system safety:** When scanning milestone directories for evidence, use `ls` or `find` to list directory contents first — never pass a directory path (e.g. `tasks/`, `slices/`) directly to the `read` tool. The `read` tool only accepts file paths, not directories.\n\nWhen done, say: \"Milestone M001 validation complete — verdict:

Vision\nBuild and validate the standalone Kerf Engine: a stateless HTTP API that accepts raster images (or existing SVGs) and returns clean, production-quality vector output (SVG, DXF, JSON) through a multi-stage pipeline of preprocessing, vectorization, post-processing, and format conversion. This is the proprietary IP core — it must work flawlessly before anything else is built.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Core Pipeline — Preprocessing + Vectorization | high — dependency installation, opencv+potrace+vtracer integration | — | ✅ | POST /engine/trace with a PNG logo returns valid SVG using both Potrace and VTracer modes |\n| S02 | Post-Processing + Output Formats (SVG, DXF, JSON) | high — dxf generation quality is hard to validate programmatically | S01 | ✅ | /engine/trace returns valid DXF and JSON output; /engine/simplify reduces node count on complex SVG |\n| S03 | Preset System + Engine Docker Packaging | low — presets are config files; docker packaging is well-understood | S02 | ✅ | GET /engine/presets returns all presets; each preset produces distinct output from same input; engine runs in Docker |\n\n\n---\n\n###

The 76 automated tests cover the full pipeline from raw bytes to SVG response. No live runtime or human-visual judgment is needed at this stage.\n\n## Preconditions\n\n- Python venv is set up: `engine/.venv/bin/python` exists\n- All dependencies installed: `cd engine && .venv/bin/python -c \"import cv2, potrace, vtracer, fastapi\"` exits 0\n- System C libraries present: `dpkg -l libpotrace-dev libagg-dev pkg-config` shows installed\n\n## Smoke Test\n\n```bash\ncd engine && .venv/bin/python -m pytest tests/ -v --tb=short\n```\n**Expected:** 76 passed, 0 failed, 0 errors. Exit code 0.\n\n## Test Cases\n\n### 1. Full test suite passes\n\n1. `cd engine && .venv/bin/python -m pytest tests/ -v`\n2. **Expected:** 76 tests pass — 24 preprocessing, 38 vectorize, 14 API integration\n\n### 2. Potrace mode produces valid SVG from PNG\n\n1. `cd engine && .venv/bin/python -m pytest tests/test_api.py::TestTraceEndpointPotrace -v`\n2. **Expected:** 4 tests pass — basic trace returns SVG, metadata has correct shape, SVG contains `` elements, custom params are accepted\n\n### 3. VTracer mode produces valid SVG from PNG\n\n1. `cd engine && .venv/bin/python -m pytest tests/test_api.py::TestTraceEndpointVtracer -v`\n2. **Expected:** 3 tests pass — basic trace returns SVG, metadata present, custom params accepted\n\n### 4. Validation rejects bad input\n\n1. `cd engine && .venv/bin/python -m pytest tests/test_api.py::TestTraceEndpointValidation -v`\n2. **Expected:** 7 tests pass — invalid mode (422), unsupported output format (422), invalid params JSON (422), empty file (422), corrupt image (422), defaults to potrace, preset ignored\n\n### 5. Preprocessing pipeline stages are individually testable\n\n1. `cd engine && .venv/bin/python -m pytest tests/test_preprocessing.py -v`\n2. **Expected:** 24 tests pass covering decode, grayscale, denoise, CLAHE, threshold, edge detect, morphological ops, and full pipeline composition\n\n### 6. Potrace and VTracer produce different output from same input\n\n1. `cd engine && .venv/bin/python -m pytest tests/test_vectorize.py::TestVtracerVsPotraceComparison -v`\n2. **Expected:** 2 tests pass — both produce valid SVG from same input, outputs differ\n\n### 7.

POST to /engine/trace with a PNG image, mode=potrace, output_format=dxf\n2. Check response content-type is \"application/dxf\"\n3. Check X-Kerf-Metadata header is valid JSON with path_count, node_count_total\n4. Check response body starts with \"0\\nSECTION\" (DXF header)\n5. **Expected:** Valid AC1015 DXF file with LWPOLYLINE entities\n\n### 3. /engine/trace returns valid JSON output\n\n1. POST to /engine/trace with a PNG image, mode=potrace, output_format=json\n2. Check response JSON has `output.paths` array and `output.metadata`\n3. Check each path has `commands` array with M/L/Z entries and `properties` dict\n4. **Expected:** JSON structure with is_closed, is_island, node_count, area per path\n\n### 4. /engine/trace works with VTracer mode\n\n1. POST to /engine/trace with a PNG image, mode=vtracer, output_format=svg\n2. **Expected:** Valid SVG output with metadata, different path structure from potrace\n\n### 5. /engine/simplify reduces node count\n\n1. POST to /engine/simplify with a complex SVG file, epsilon=2.0\n2. Compare node_count_total in response metadata\n3. **Expected:** node_count_total is less than original SVG path node count\n\n### 6. /engine/simplify supports all output formats\n\n1. POST to /engine/simplify with SVG file, output_format=dxf\n2. POST to /engine/simplify with SVG file, output_format=json\n3. POST to /engine/simplify with SVG file, output_format=svg\n4. **Expected:** All three return valid output in their respective formats\n\n### 7. Island detection identifies interior paths\n\n1. Trace or simplify an image/SVG with interior holes (e.g., letter \"O\" shape)\n2. Check JSON output for paths with `is_island: true`\n3. Check DXF output for entities on the \"ISLANDS\" layer\n4. **Expected:** Interior counter-paths correctly flagged as islands\n\n## Edge Cases\n\n### Empty file upload\n\n1. POST to /engine/trace with an empty file\n2. **Expected:** HTTP 422 with detail \"Uploaded file is empty\"\n\n### Invalid output_format\n\n1. POST to /engine/trace with output_format=pdf\n2. **Expected:** HTTP 422 with detail listing valid formats (dxf, json, svg)\n\n### Non-SVG file to /engine/simplify\n\n1. POST to /engine/simplify with a PNG file\n2. **Expected:** HTTP 422 with detail \"File does not appear to be a valid SVG\"\n\n### Binary file to /engine/simplify\n\n1. POST to /engine/simplify with random binary data\n2. **Expected:** HTTP 422 with detail \"File is not valid UTF-8 text\"\n\n### Default epsilon on /engine/simplify\n\n1. POST to /engine/simplify without specifying epsilon\n2. **Expected:** Uses default epsilon=1.0, returns valid output\n\n## Failure Signals\n\n- Any test in `test_api.py`, `test_postprocess.py`, or `test_output.py` fails\n- DXF output doesn't start with \"0\\nSECTION\" (malformed DXF)\n- JSON output missing `commands` or `properties` in path objects\n- X-Kerf-Metadata header missing or invalid JSON on DXF responses\n- node_count_total or path_count is 0 for non-trivial inputs\n\n## Not Proven By This UAT\n\n- Visual quality of DXF output in actual CAD software (Inkscape, AutoCAD)\n- Curve fidelity after bezier-to-polyline linearization\n- Performance under large/complex SVG inputs (no load testing)\n- viewBox/transform matrix handling in SVG path parsing\n\n## Notes for Tester\n\n- ezdxf emits pyparsing deprecation warnings during tests — these are harmless library-internal warnings, not bugs\n- Tests generate images programmatically via numpy (pattern P001) — no fixture files needed\n- Always use `.venv/bin/python -m pytest`, never bare `python` (pattern P002)\n===\n# S03: Preset System + Engine Docker Packaging — UAT\n\n**Milestone:** M001\n**Written:** 2026-03-26T04:52:09.425Z\n\n# S03: Preset System + Engine Docker Packaging — UAT\n\n**Milestone:** M001\n**Written:** 2026-03-26\n\n## UAT Type\n\n- UAT mode: mixed (artifact-driven for presets, live-runtime for Docker)\n- Why this mode is sufficient: Preset system is config + API — tests validate behavior. Docker packaging requires live container verification.\n\n## Preconditions\n\n- Engine venv exists at `engine/.venv/` with all deps installed\n- Docker daemon running\n- Port 8100 available for test container\n- Working directory is project root (`/home/aux/development/xpltdco/kerf-engine`)\n\n## Smoke Test\n\n```bash\ncd engine && .venv/bin/python -m pytest tests/ -v -k preset && echo \"SMOKE OK\"\n```\nExpected: 28 tests pass, exit 0.\n\n## Test Cases\n\n### 1. All 5 presets load and are returned by GET endpoint\n\n1. Start engine: `cd engine && .venv/bin/python -m uvicorn main:app --port 8099 &`\n2. `curl -s http://localhost:8099/engine/presets | python3 -m json.tool`\n3. **Expected:** JSON with keys: sign, patch, stencil, detailed, custom. Each has name, description, preprocessing, vectorization, postprocessing sections.\n\n### 2. Default preset is 'sign' when none specified\n\n1. POST a PNG to `/engine/trace` without specifying `preset`\n2. **Expected:** Response uses sign preset defaults (potrace mode, alphamax=0.8, opttolerance=0.3)\n\n### 3. Different presets produce different output from same input\n\n1. POST the same PNG to `/engine/trace` with preset=sign\n2. POST the same PNG to `/engine/trace` with preset=detailed\n3. **Expected:** SVG outputs differ — sign produces fewer nodes (aggressive simplification) vs detailed (max fidelity)\n\n### 4. User params override preset defaults\n\n1. POST to `/engine/trace` with preset=sign and params={\"threshold_manual\": 200}\n2. **Expected:** Response uses threshold_manual=200 (user override) but other params from sign preset\n\n### 5. Unknown preset is rejected\n\n1. POST to `/engine/trace` with preset=nonexistent\n2. **Expected:** 400 error with message about invalid preset\n\n### 6. Docker image builds and starts healthy\n\n1. `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .`\n2. `docker run --rm -d --name kerf-engine-uat -p 8100:8000 kerf-engine:dev`\n3. `sleep 6`\n4. `curl -sf http://localhost:8100/engine/health`\n5. **Expected:** Returns `{\"status\":\"ok\"}`\n6. `docker inspect kerf-engine-uat --format='{{json .State.Health.Status}}'`\n7. **Expected:** Returns `\"healthy\"`\n8. `docker stop kerf-engine-uat`\n\n### 7. Engine container serves presets endpoint\n\n1. Start container as in test 6\n2. `curl -sf http://localhost:8100/engine/presets | python3 -m json.tool`\n3. **Expected:** Same 5 presets as local endpoint test\n4. `docker stop kerf-engine-uat`\n\n### 8. Engine image contains no App code\n\n1. `docker run --rm kerf-engine:dev ls /app/`\n2. **Expected:** Only engine files: main.py, api/, pipeline/, output/, presets/. No app/, frontend/, or node_modules/.\n\n## Edge Cases\n\n### Custom preset with no user params uses pipeline defaults\n\n1. POST to `/engine/trace` with preset=custom and no params\n2. **Expected:** Succeeds using pipeline code defaults (potrace mode from custom.json vectorization section)\n\n### Preset with mode override\n\n1. POST to `/engine/trace` with preset=sign (which defaults to potrace) and mode=vtracer\n2. **Expected:** Uses vtracer mode but sign preset's preprocessing/postprocessing params\n\n## Failure Signals\n\n- Any preset test fails (28 tests must pass)\n- Docker build fails (missing system deps, pip install errors)\n- Container starts but /engine/health returns non-200\n- Docker health status shows \"unhealthy\"\n- /engine/presets returns fewer than 5 presets\n- Same preset applied to different images produces identical SVG (preset not taking effect)\n\n## Not Proven By This UAT\n\n- Preset quality tuning (whether sign preset actually produces good signage output — that requires human visual evaluation)\n- Container performance under load\n- Container image size optimization\n- Production deployment (compose, networking, volumes)\n\n## Notes for Tester\n\n- The ezdxf deprecation warnings in test output are harmless (L004) — ignore them\n- Docker build uses cached layers after first build — subsequent builds are fast\n- Port 8100 is used for Docker tests to avoid conflicting with local dev on 8000\n"}],"isError":false,"timestamp":1774500784755}} +{"type":"message","id":"438816b1","parentId":"242761e6","timestamp":"2026-03-26T04:54:04.940Z","message":{"role":"assistant","content":[{"type":"text","text":"Now I have all the evidence.

PostProcessResult is the universal intermediate representation. 169 tests pass including integration tests that exercise the full S01→S02 pipeline path.\n- **Response shape evolution:** S01 defined `{output, format, metadata: {path_count, node_count_total, open_paths, warnings, processing_ms}}`. S02 extended metadata to include `island_count`.

This is the proprietary IP core — it must work flawlessly before anything else is built.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Core Pipeline — Preprocessing + Vectorization | high — dependency installation, opencv+potrace+vtracer integration | — | ✅ | POST /engine/trace with a PNG logo returns valid SVG using both Potrace and VTracer modes |\n| S02 | Post-Processing + Output Formats (SVG, DXF, JSON) | high — dxf generation quality is hard to validate programmatically | S01 | ✅ | /engine/trace returns valid DXF and JSON output; /engine/simplify reduces node count on complex SVG |\n| S03 | Preset System + Engine Docker Packaging | low — presets are config files; docker packaging is well-understood | S02 | ✅ | GET /engine/presets returns all presets; each preset produces distinct output from same input; engine runs in Docker |\n\n---\n\n### S01 Summary\nSource: `.gsd/milestones/M001/slices/S01/S01-SUMMARY.md`\n\n---\nid: S01\nmilestone: M001\nstatus: complete\ntasks_completed: 5\ntasks_total: 5\ncompleted_at: 2026-03-26T04:30:00.000Z\n---\n\n# S01: Core Pipeline — Preprocessing + Vectorization\n\n## Goal\nStand up FastAPI server with OpenCV preprocessing pipeline and dual-mode vectorization (Potrace + VTracer). Establish the repo structure, dependencies, and core /engine/trace endpoint.\n\n## Outcome\nAll 5 tasks completed successfully. The engine accepts PNG uploads via POST /engine/trace and returns SVG output with metadata using either Potrace or VTracer mode. Full test suite: 76 tests passing.\n\n## What Was Built\n\n### T01: Project Scaffold\nCreated engine/ Python project with FastAPI skeleton, pyproject.toml, all dependencies (fastapi, uvicorn, opencv-python-headless, pypotrace, vtracer, python-multipart, Pillow). Verified uvicorn starts cleanly.\n\n### T02: OpenCV Preprocessing Pipeline\nImplemented `engine/pipeline/preprocessing.py` with full pipeline: grayscale conversion, bilateral filter denoise, CLAHE contrast enhancement, Otsu thresholding, optional Canny edge detection, morphological operations. All stages tunable via parameters dict.\n\n### T03: Potrace Vectorization (Mode A)\nImplemented `potrace_trace()` in `engine/pipeline/vectorize.py`. Converts preprocessed binary images to SVG via pypotrace with tunable params (turdsize, alphamax, opticurve, opttolerance).\n\n### T04: VTracer Vectorization (Mode B)\nImplemented `vtracer_trace()` in `engine/pipeline/vectorize.py`. Converts grayscale or color images to SVG via vtracer Python bindings with tunable params (colormode, filter_speckle, color_precision, etc.).\n\n### T05: API Endpoint + Integration Tests\nCreated `engine/api/routes.py` with POST /engine/trace endpoint. Accepts multipart form-data (file, mode, output_format, preset, params). Returns JSON with SVG output and metadata (path_count, node_count_total, open_paths, processing_ms, warnings). 14 integration tests covering both modes, metadata shape, custom params, and validation errors.\n\n## Key Files\n- `engine/main.py` — FastAPI app entry point\n- `engine/api/routes.py` — /engine/trace endpoint\n- `engine/pipeline/preprocessing.py` — OpenCV preprocessing pipeline\n- `engine/pipeline/vectorize.py` — Potrace + VTracer vectorization\n- `engine/tests/` — 76 tests (unit + integration)\n\n## Key Decisions\n- SVG metadata extraction via regex (lightweight, no XML parser dependency)\n- Vectorize params filtered by known param names per mode\n- Bilateral filter chosen over Gaussian for edge-preserving denoise\n- CLAHE for contrast rather than simple histogram equalization\n\n## Verification\nFull test suite: `cd engine && .venv/bin/python -m pytest tests/ -v` — 76 passed\n\n## Demo\nPOST /engine/trace with a PNG logo returns valid SVG using both Potrace and VTracer modes.\n\n## Known Limitations\n- Output format is SVG-only — DXF and JSON deferred to S02\n- `preset` parameter accepted but ignored — preset system deferred to S03\n- No Docker packaging yet — deferred to S03\n- Tests must run with `.venv/bin/python -m pytest`, not bare `python`\n\n## Forward Intelligence\n\n### What the next slice should know\n- Response shape: `{output: str, format: str, metadata: {path_count, node_count_total, open_paths, warnings, processing_ms}}`. S02 must extend for DXF/JSON without breaking this contract.\n- VTracer returns SVG with XML declaration + generator comment; Potrace's `_path_to_svg()` returns bare SVG. Post-processing must handle both.\n- User params are filtered by known names per mode in routes.py lines 80-91. New params for S02 post-processing stages must be added to these filter lists.\n\n### What's fragile\n- `_extract_svg_metadata()` regex assumes `` — if output format changes, metadata counts silently return 0.\n- pypotrace Bitmap requires uint32 data — feeding other dtypes directly will segfault (see L003 in KNOWLEDGE.md).\n\n### Authoritative diagnostics\n- `engine/.venv/bin/python -m pytest tests/ -v` — full pipeline health check, runs in <1s.\n- `GET /health` returns `{\"status\": \"ok\"}` — confirms FastAPI is running.\n\n### What assumptions changed\n- VTracer Python bindings work via `convert_raw_image_to_svg()` with PNG bytes — no subprocess needed (original plan suggested subprocess might be required).\n- Test images are generated programmatically via numpy, not loaded from fixture files.\n\n---\n\n### S02 Summary\nSource: `.gsd/milestones/M001/slices/S02/S02-SUMMARY.md`\n\n---\nid: S02\nparent: M001\nmilestone: M001\nprovides:\n - postprocess_svg() function for RDP simplification + island detection + node counting\n - Output generators: generate_dxf(), generate_json(), generate_svg()\n - /engine/simplify endpoint for SVG-to-SVG/DXF/JSON simplification\n - output_format routing on /engine/trace (svg, dxf, json)\n - _format_response() pattern for consistent multi-format responses\nrequires:\n - slice: S01\n provides: Core pipeline: preprocessing + potrace_trace() + vtracer_trace() producing raw SVG output\naffects:\n - S03\nkey_files:\n - engine/pipeline/postprocess.py\n - engine/output/dxf.py\n - engine/output/json_output.py\n - engine/output/svg.py\n - engine/output/__init__.py\n - engine/api/routes.py\n - engine/tests/test_postprocess.py\n - engine/tests/test_output.py\n - engine/tests/test_api.py\nkey_decisions:\n - DXF output as raw bytes with application/dxf content-type and metadata in X-Kerf-Metadata header\n - postprocess_svg() replaces regex metadata extraction — full XML path parsing for structured PathInfo objects\n - _format_response() shared helper for consistent response shaping across endpoints\n - Islands placed on separate ISLANDS layer in DXF for downstream CAM tool compatibility\n - Bezier curves linearized during post-processing for RDP simplification and DXF polyline generation\npatterns_established:\n - PostProcessResult as the universal intermediate representation consumed by all output generators\n - Output generators are pure functions: PostProcessResult → bytes/string, no side effects\n - _format_response() pattern for consistent multi-format API responses with metadata\nobservability_surfaces:\n - Metadata in every API response: path_count, node_count_total, open_paths, island_count, warnings, processing_ms\n - X-Kerf-Metadata header on DXF responses carries the same metadata as JSON envelope responses\ndrill_down_paths:\n - .gsd/milestones/M001/slices/S02/tasks/T01-SUMMARY.md\n - .gsd/milestones/M001/slices/S02/tasks/T02-SUMMARY.md\n - .gsd/milestones/M001/slices/S02/tasks/T03-SUMMARY.md\nduration: \"\"\nverification_result: passed\ncompleted_at: 2026-03-26T04:41:57.970Z\nblocker_discovered: false\n---\n\n# S02: Post-Processing + Output Formats (SVG, DXF, JSON)\n\n**Full post-processing pipeline (RDP simplification, island detection, open path repair) with three output format generators (SVG, DXF, JSON) and /engine/simplify endpoint — 169 tests passing.**\n\n## What Happened\n\nThis slice added the complete post-processing layer and output format system to the Kerf Engine pipeline.\n\n**T01 — Post-processing module** (`engine/pipeline/postprocess.py`, 414 lines): Built the core `postprocess_svg()` function that parses raw SVG output from vectorizers into structured `PathInfo` objects. Implements: (1) SVG path d-attribute parsing supporting M, L, C, Q, Z, H, V commands with relative variants; (2) Ramer-Douglas-Peucker simplification with tunable epsilon; (3) Island detection via signed-area calculation (negative area = clockwise winding = interior hole); (4) Open path detection by comparing start/end coordinates; (5) Per-path and aggregate node counting. The `PostProcessResult` dataclass carries all structured data downstream to output generators.\n\n**T02 — Output format generators** (`engine/output/`): Created three format generators consuming `PostProcessResult`. DXF generator (`dxf.py`, 66 lines) uses ezdxf to create AC1015 (AutoCAD R2000) documents with LWPOLYLINE entities — islands go on an \"ISLANDS\" layer, outer contours on layer \"0\", and closed paths get the polyline close flag. JSON generator (`json_output.py`, 76 lines) outputs structured path arrays with M/L/Z commands and per-path properties (is_closed, is_island, area, node_count). SVG generator (`svg.py`, 22 lines) returns the simplified SVG string from PostProcessResult.\n\n**T03 — API integration** (`engine/api/routes.py`, 175 lines): Wired post-processing into `/engine/trace` after vectorization. Added `output_format` parameter routing (svg/dxf/json). Created `/engine/simplify` endpoint accepting SVG upload + epsilon + output_format. Built `_format_response()` shared helper for consistent response shaping. DXF returns raw bytes with `application/dxf` content type and metadata in `X-Kerf-Metadata` header. SVG and JSON return JSON envelopes with output + metadata. Wrote 35 integration tests covering all format combinations for both endpoints.\n\n## Verification\n\nAll verification runs use `.venv/bin/python -m pytest` per project pattern P002.\n\n- `engine/tests/test_postprocess.py`: Tests for RDP simplification, island detection, open path detection, SVG parsing, node counting — all pass.\n- `engine/tests/test_output.py`: Tests for DXF structure (AC1015, LWPOLYLINE entities, closed flags, island layers), JSON structure (path commands, metadata), SVG output, round-trip consistency — all pass.\n- `engine/tests/test_api.py`: 35 integration tests covering /engine/trace (SVG, JSON, DXF output for potrace and vtracer modes, validation errors) and /engine/simplify (SVG, JSON, DXF output, validation errors, epsilon defaults) — all pass.\n- Full suite: 169 tests pass in 0.92s with only ezdxf pyparsing deprecation warnings (harmless).\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nReplaced the old _extract_svg_metadata() regex-based function entirely with postprocess_svg() pipeline. D003 (regex-based metadata extraction) is now superseded — full XML/path parsing is required for DXF/JSON generation. DXF responses use raw binary Response with X-Kerf-Metadata header instead of a JSON envelope, since DXF is binary data.\n\n## Known Limitations\n\n- Bezier curves (C, Q commands) in SVG paths are sampled to linear segments during post-processing. This means DXF output uses polylines only, not splines. Adequate for CNC/laser use cases but loses mathematical curve precision.\n- RDP simplification operates on linearized coordinates, not on the original bezier control points.

Built loader.py with in-memory caching and resolve_params() that merges preset defaults with user-supplied overrides (user wins on conflicts). Mode now comes from the preset unless the user explicitly overrides it. Added GET /engine/presets endpoint that returns all available presets with their full config. Wired preset selection into the /engine/trace pipeline so posting with `preset: \"stencil\"` applies that preset's params. Postprocessing params (close_tolerance, auto_close) are now also preset-driven. 28 preset-specific tests validate loader logic, param resolution, endpoint response shape, per-preset integration, and cross-preset output differentiation.\n\n**T02 — Docker Packaging:** Created docker/Dockerfile.engine as a two-stage build. Builder stage installs build-essential, libagg-dev, libpotrace-dev to compile pypotrace, installs all Python deps into /opt/venv. Runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl), copies the venv and only engine source — no App code. Added GET /engine/health returning {\"status\":\"ok\"} on the router for namespace consistency. Docker HEALTHCHECK instruction pings /engine/health (15s interval, 5s timeout, 10s start-period, 3 retries). Container builds cleanly, starts, reports healthy, and serves all engine endpoints.\n\n## Verification\n\nAll 196 tests pass (28 preset-specific). Docker image builds from project root with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` (exit 0). Container starts on port 8100, /engine/health returns {\"status\":\"ok\"}, Docker health status shows \"healthy\" with 0 failing streak, /engine/presets returns all 5 presets with full config. Container contains only engine source — no App files.\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nT02 verification command in the plan used `cd /vmPool/r/repos/xpltdco/kerf` which doesn't exist — the correct build context is the project root at `/home/aux/development/xpltdco/kerf-engine`. T01 added auto_close and close_tolerance postprocessing params to the preset-driven trace flow (already supported by postprocess_svg but not previously exposed through the API). T02 added /engine/health alongside the existing /health root endpoint for namespace consistency.\n\n## Known Limitations\n\nPreset files are baked into the Docker image at build time — adding/editing presets requires a rebuild. No runtime preset hot-reload. Custom preset has empty param sections which means pipeline code defaults apply — these defaults aren't documented in the preset file itself.\n\n## Follow-ups\n\nConsider adding preset validation on load (schema check). Consider documenting pipeline defaults in the custom preset for discoverability. Future M002/M003 work will consume the engine container as a service.\n\n## Files Created/Modified\n\n- `engine/presets/sign.json` — Sign preset — aggressive simplification for signage vectorization\n- `engine/presets/patch.json` — Patch preset — smooth curves with auto-close for embroidery\n- `engine/presets/stencil.json` — Stencil preset — heavy simplification with fixed threshold\n- `engine/presets/detailed.json` — Detailed preset — max fidelity for illustrations\n- `engine/presets/custom.json` — Custom preset — empty defaults, user controls everything\n- `engine/presets/loader.py` — Preset loader with caching, listing, and param merge resolution\n- `engine/api/routes.py` — Added GET /engine/presets, GET /engine/health, wired preset into /engine/trace\n- `engine/tests/test_presets.py` — 28 tests covering loader, resolution, endpoint, integration, cross-preset differentiation\n- `docker/Dockerfile.engine` — Multi-stage Dockerfile: builder compiles pypotrace, runtime uses slim image with engine source only\n- `.dockerignore` — Excludes .git, .venv, __pycache__, .gsd, node_modules from Docker build context\n\n---\n\n### Decisions\nSource: `.gsd/DECISIONS.md`\n\n# Decisions Register\n\n\n\n| # | When | Scope | Decision | Choice | Rationale | Revisable? | Made By |\n|---|------|-------|----------|--------|-----------|------------|---------|\n| D001 | | architecture | Engine/App architectural relationship | Engine is standalone module, App is a consumer. Zero coupling — App calls Engine only via HTTP API. | Engine is proprietary IP that must be embeddable into future applications independently. Clean input/output contracts enable this. | No | human |\n| D002 | | architecture | Build order and gating strategy | Build Engine first (M001), then App canvas (M002), then Export+Deploy+Embed (M003). Human checkpoints gate each transition. | Brief explicitly mandates: validate engine output quality before building canvas UI, validate canvas before export/deploy. Engine is the hardest and most valuable piece. | No | human |\n| D003 | | engine | Post-processing replaces regex metadata extraction | postprocess_svg() pipeline replaces old _extract_svg_metadata() regex approach; all SVG paths are parsed into structured PathInfo objects with coordinates, area, island status | Structured path data is needed for DXF/JSON output generation, RDP simplification, and island detection. XML parsing is now necessary since we need actual coordinate data, not just counts. This supersedes D003's regex approach. | No | agent |\n| D004 | | architecture | Engine Docker image build strategy | Multi-stage build: builder stage compiles pypotrace with build-essential/libagg-dev/libpotrace-dev, runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl). Only engine source is copied — no App code. | Multi-stage keeps the runtime image small by excluding build tools. Copying only engine source enforces the Engine/App separation (D001). curl is included for Docker HEALTHCHECK. | Yes | agent |\n\n---\n\n### Project Knowledge\nSource: `.gsd/KNOWLEDGE.md`\n\n# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit. Add entries when you discover something worth remembering.\n\n## Rules\n\n| # | Scope | Rule | Why | Added |\n|---|-------|------|-----|-------|\n\n## Patterns\n\n| # | Pattern | Where | Notes |\n|---|---------|-------|-------|\n| P001 | Test images generated programmatically via numpy | engine/tests/ | No fixture image files checked in. Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them. Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003). All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n| L007 | Docker build context must be project root, not engine/ | Dockerfile.engine uses `COPY engine/...` paths relative to project root | Always build with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` from project root | Docker |\n| L008 | Engine container has dual health endpoints | /health on root (main.py) and /engine/health on router (routes.py) both exist | Use /engine/health for Docker HEALTHCHECK and external probes for namespace consistency | engine API, Docker |\n\n---\n\n---\nid: {{milestoneId}}\nprovides:\n - {{whatThisMilestoneProvides}}\nkey_decisions:\n - {{decision}}\npatterns_established:\n - {{pattern}}\nobservability_surfaces:\n - {{status endpoint, structured log, persisted failure state, diagnostic command, or none}}\nrequirement_outcomes:\n - id: {{requirementId}}\n from_status: {{active|blocked|deferred}}\n to_status: {{validated|deferred|blocked|out_of_scope}}\n proof: {{whatEvidenceSupportsThisTransition}}\nduration: {{duration}}\nverification_result: passed\ncompleted_at: {{date}}\n---\n\n# {{milestoneId}}: {{milestoneTitle}}\n\n\n\n**{{oneLiner}}**\n\n## What Happened\n\n\n\n{{crossSliceNarrative}}\n\n## Cross-Slice Verification\n\n\n\n{{howSuccessCriteriaWereVerified}}\n\n## Requirement Changes\n\n\n\n- {{requirementId}}: {{fromStatus}} → {{toStatus}} — {{evidence}}\n\n## Forward Intelligence\n\n\n\n### What the next milestone should know\n- {{insightThatWouldHelpDownstreamWork}}\n\n### What's fragile\n- {{fragileAreaOrThinImplementation}} — {{whyItMatters}}\n\n### Authoritative diagnostics\n- {{whereAFutureAgentShouldLookFirst}} — {{whyThisSignalIsTrustworthy}}\n\n### What assumptions changed\n- {{originalAssumption}} — {{whatActuallyHappened}}\n\n## Files Created/Modified\n\n- `{{filePath}}` — {{description}}\n- `{{filePath}}` — {{description}}\n\n### Output Template: Milestone Summary\nSource: `templates/milestone-summary.md`\n\nThen:\n1. Use the **Milestone Summary** output template from the inlined context above\n2. \n3. **Verify code changes exist.** Run `git diff --stat HEAD $(git merge-base HEAD main) -- ':!.gsd/'` (or the equivalent for the integration branch). If no non-`.gsd/` files appear in the diff, the milestone produced only planning artifacts and no actual code. Record this as a **verification failure**.\n4. Verify each **success criterion** from the milestone definition in `.gsd/milestones/M001/M001-ROADMAP.md`. For each criterion, confirm it was met with specific evidence from slice summaries, test results, or observable behavior. Record any criterion that was NOT met as a **verification failure**.\n5. Verify the milestone's **definition of done** — all slices are `[x]`, all slice summaries exist, and any cross-slice integration points work correctly. Record any unmet items as a **verification failure**.\n6. Validate **requirement status transitions**. For each requirement that changed status during this milestone, confirm the transition is supported by evidence. Requirements can move between Active, Validated, Deferred, Blocked, or Out of Scope — but only with proof.\n\n### Verification Gate — STOP if verification failed\n\n**If ANY verification failure was recorded in steps 3, 4, or 5, you MUST follow the failure path below. Do NOT proceed to step 7.**\n\n**Failure path** (verification failed):\n- Do NOT call `gsd_complete_milestone` — the milestone must not be marked as complete.\n- Do NOT update `.gsd/PROJECT.md` to reflect completion.\n- Do NOT update `.gsd/REQUIREMENTS.md` to mark requirements as validated.\n- Write a clear summary of what failed and why to help the next attempt.\n- Say: \"Milestone M001 verification FAILED — not complete.\" and stop.\n\n**Success path** (all verifications passed — continue with steps 7–11):\n\n7. **Persist completion through `gsd_complete_milestone`.** Call it with: `milestoneId`, `title`, `oneLiner`, `narrative`, `successCriteriaResults`, `definitionOfDoneResults`, `requirementOutcomes`, `keyDecisions`, `keyFiles`, `lessonsLearned`, `followUps`, `deviations`, `verificationPassed: true`. The tool updates the milestone status in the DB, renders `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M001/M001-SUMMARY.md`, and validates all slices are complete before proceeding.\n8. For each requirement whose status changed in step 6, call `gsd_requirement_update` with the requirement ID and updated `status` and `validation` fields — the tool regenerates `.gsd/REQUIREMENTS.md` automatically.\n9. Update `.gsd/PROJECT.md` to reflect milestone completion and current project state.\n10. Review all slice summaries for cross-cutting lessons, patterns, or gotchas that emerged during this milestone. Append any non-obvious, reusable insights to `.gsd/KNOWLEDGE.md`.\n11. Do not commit manually — the system auto-commits your changes after this unit completes.\n- Say: \"Milestone M001 complete.\"\n\n**Important:** Do NOT skip the code change verification, success criteria, or definition of done verification (steps 3-5). The milestone summary must reflect actual verified outcomes, not assumed success. Verification failures BLOCK completion — there is no override. The milestone stays in its current state until issues are resolved and verification is re-run.\n\n**File system safety:** When scanning milestone directories for evidence, use `ls` or `find` to list directory contents first — never pass a directory path (e.g. `tasks/`, `slices/`) directly to the `read` tool. The `read` tool only accepts file paths, not directories.","display":false,"id":"0e560ce7","parentId":"1e857da6","timestamp":"2026-03-26T04:54:42.511Z"} +{"type":"message","id":"03d9fd99","parentId":"0e560ce7","timestamp":"2026-03-26T04:54:47.722Z","message":{"role":"assistant","content":[{"type":"text","text":"\n\nI'll now verify the milestone and complete it.

Each is evaluated below:\n\n### S01: \"POST /engine/trace with a PNG logo returns valid SVG using both Potrace and VTracer modes\"\n- [x] **PASS** — `POST /engine/trace` endpoint exists in `engine/api/routes.py`. S01 summary confirms 14 integration tests covering both Potrace and VTracer modes. S01-UAT test case 7 verifies the response shape contract. 76 tests pass including mode-specific tests (`TestTraceEndpointPotrace`, `TestTraceEndpointVtracer`). Full test suite re-run confirms 196 tests pass (S01 tests still green).\n\n### S02: \"/engine/trace returns valid DXF and JSON output; /engine/simplify reduces node count on complex SVG\"\n- [x] **PASS** — `output_format` parameter routing confirmed in routes.py (svg/dxf/json). DXF generator (`engine/output/dxf.py`) produces AC1015 DXF with LWPOLYLINE entities. JSON generator (`engine/output/json_output.py`) outputs structured path arrays. `/engine/simplify` endpoint confirmed in routes.py. 35 API integration tests cover all format combinations for both endpoints. S02-UAT defines test cases for DXF binary response with X-Kerf-Metadata header, JSON path structure, and simplification node reduction.\n\n### S03: \"GET /engine/presets returns all presets; each preset produces distinct output from same input; engine runs in Docker\"\n- [x] **PASS** — `GET /engine/presets` endpoint confirmed in routes.py. All 5 preset JSON files verified on disk (sign, patch, stencil, detailed, custom) with correct structure (preprocessing/vectorization/postprocessing sections). 28 preset-specific tests include cross-preset output differentiation tests. `docker/Dockerfile.engine` implements multi-stage build with HEALTHCHECK. S03 summary confirms container builds, starts healthy, and serves all endpoints.\n\n## Slice Delivery Audit\n## Slice Delivery Audit\n\n| Slice | Claimed Deliverable | Delivered? | Evidence |\n|-------|-------------------|-----------|----------|\n| S01 | FastAPI server with /engine/trace, OpenCV preprocessing, Potrace + VTracer vectorization | ✅ Yes | `engine/main.py`, `engine/api/routes.py` (POST /engine/trace), `engine/pipeline/preprocessing.py` (OpenCV pipeline), `engine/pipeline/vectorize.py` (potrace_trace + vtracer_trace). 76 tests passing. |\n| S01 | 76 tests | ✅ Yes | All included in 196-test suite; original S01 tests still pass. |\n| S02 | postprocess_svg() with RDP simplification, island detection, node counting | ✅ Yes | `engine/pipeline/postprocess.py` (414 lines) with PathInfo objects, RDP, island detection via signed-area. |\n| S02 | Output generators: DXF, JSON, SVG | ✅ Yes | `engine/output/dxf.py` (66 lines, ezdxf AC1015), `engine/output/json_output.py` (76 lines), `engine/output/svg.py` (22 lines). |\n| S02 | /engine/simplify endpoint | ✅ Yes | Confirmed in routes.py — POST /engine/simplify with epsilon + output_format params. |\n| S02 | output_format routing on /engine/trace | ✅ Yes | Confirmed in routes.py — accepts svg/dxf/json. |\n| S02 | 169 tests | ✅ Yes | All included in 196-test suite. |\n| S03 | 5 presets (sign, patch, stencil, detailed, custom) | ✅ Yes | All 5 JSON files present in `engine/presets/` with correct structure verified. |\n| S03 | Preset loader with param merge/resolution | ✅ Yes | `engine/presets/loader.py` with resolve_params() — user overrides preset defaults. |\n| S03 | GET /engine/presets endpoint | ✅ Yes | Confirmed in routes.py. |\n| S03 | Docker image with healthcheck | ✅ Yes | `docker/Dockerfile.engine` — multi-stage build, HEALTHCHECK pings /engine/health. |\n| S03 | GET /engine/health endpoint | ✅ Yes | Confirmed in routes.py. |\n| S03 | 196 total tests | ✅ Yes | Full suite run: `196 passed, 21 warnings in 0.96s`. |\n\n## Cross-Slice Integration\n## Cross-Slice Integration\n\n### S01 → S02 Boundary\n- **Contract:** S01 produces raw SVG strings from potrace_trace() and vtracer_trace(). S02 consumes these via postprocess_svg().\n- **Status:** ✅ Aligned. S02 summary confirms postprocess_svg() replaced the old regex metadata extraction (D003). PostProcessResult is the universal intermediate representation. 169 tests pass including integration tests that exercise the full S01→S02 pipeline path.\n- **Response shape evolution:** S01 defined `{output, format, metadata: {path_count, node_count_total, open_paths, warnings, processing_ms}}`. S02 extended metadata to include `island_count`. This is additive — backward compatible.\n\n### S02 → S03 Boundary\n- **Contract:** S03 consumes the post-processing pipeline and output format generators. Presets configure the full pipeline (preprocessing + vectorization + postprocessing params).\n- **Status:** ✅ Aligned. S03 summary confirms resolve_params() merges preset defaults with user overrides. Presets contain preprocessing, vectorization, and postprocessing sections that feed directly into the pipeline stages built in S01/S02. 28 preset integration tests validate end-to-end preset→pipeline→output flow.\n\n### Cross-cutting: routes.py\n- The API router (routes.py) was modified by all three slices. Final state (7364 bytes) contains all endpoints from all slices: /engine/health, /engine/presets, /engine/trace, /engine/simplify. No regressions — 196 tests confirm all endpoints work together.\n\n### No boundary mismatches detected.\n\n## Requirement Coverage\n## Requirement Coverage\n\nNo formal requirements (REQUIREMENTS.md) were defined for this milestone. The project uses decision records (D001–D004) and per-slice success criteria as the governing specification.\n\n**Decision compliance check:**\n- **D001** (Engine/App separation): ✅ Docker image copies only engine source — no App code. Engine is a standalone HTTP API with no App dependencies.\n- **D002** (Build order): ✅ M001 builds Engine first as specified. App canvas (M002) and Export/Deploy (M003) are deferred.\n- **D003** (Post-processing replaces regex): ✅ Superseded as documented. postprocess_svg() provides structured PathInfo objects.\n- **D004** (Multi-stage Docker build): ✅ Implemented exactly as specified — builder compiles pypotrace, runtime uses slim image with only runtime libs.\n\nNo unaddressed requirements exist.\n\n## Verdict Rationale\n**Verdict: PASS**\n\nAll three slices delivered exactly what the roadmap specified:\n\n1. **S01** — Core pipeline with preprocessing + dual vectorization modes (Potrace/VTracer) via POST /engine/trace. 76 tests established the foundation.\n\n2. **S02** — Full post-processing (RDP simplification, island detection, open path repair) with three output format generators (SVG, DXF, JSON). /engine/simplify endpoint added. Test suite grew to 169.\n\n3. **S03** — 5 tuned presets with merge-based param resolution, GET /engine/presets endpoint, and multi-stage Docker image with healthcheck. Final test suite: 196 tests, all passing in under 1 second.\n\n**Evidence is strong:**\n- 196 tests pass (verified by live test run, 0.96s, exit 0)\n- All source files exist on disk with expected structure\n- All 4 API endpoints confirmed in routes.py\n- All 5 preset configs verified with correct JSON structure\n- Dockerfile exists with multi-stage build and HEALTHCHECK\n- Cross-slice integration points align — no boundary mismatches\n- All 4 architectural decisions (D001–D004) are satisfied\n- UAT artifacts exist for all 3 slices with comprehensive test cases\n\nNo gaps, regressions, or missing deliverables found. The milestone is ready for completion.\n"}],"isError":false,"timestamp":1774500946133}} +{"type":"message","id":"eb63fea3","parentId":"f20759f4","timestamp":"2026-03-26T04:56:42.984Z","message":{"role":"assistant","content":[{"type":"text","text":"All verification checks pass.

POST /engine/trace accepts PNG uploads and returns SVG output with metadata. 76 tests established the foundation and patterns (programmatic test images via numpy, .venv pytest runner).\n\n**S02 (Post-Processing + Output Formats)** added the post-processing layer that parses raw SVG paths into structured PathInfo objects, implements Ramer-Douglas-Peucker simplification, detects islands via signed-area calculation, and identifies open paths. Three output generators consume PostProcessResult: DXF (AC1015 with LWPOLYLINE entities, islands on separate layer), JSON (structured path commands with properties), and SVG (simplified output). A /engine/simplify endpoint was added for SVG-to-SVG/DXF/JSON conversion. The old regex-based metadata extraction was replaced entirely by full path parsing — a necessary evolution to support DXF coordinate output and island detection.\n\n**S03 (Presets + Docker)** wrapped the milestone with a preset system (5 tuned configs: sign, patch, stencil, detailed, custom) that drives the entire pipeline via merge-based param resolution (preset defaults + user overrides). GET /engine/presets exposes all configs. Docker packaging uses a multi-stage build — builder stage compiles pypotrace with C dependencies, runtime stage uses python:3.11-slim with only engine source (no App code), enforcing the Engine/App separation mandated by D001. Container includes HEALTHCHECK on /engine/health.\n\nThe slices integrated cleanly: S01's vectorizer output feeds S02's postprocess_svg(), which produces PostProcessResult consumed by output generators; S03's preset system configures all three pipeline stages. routes.py evolved across all slices with no regressions — the final 196-test suite validates every endpoint and format combination.","oneLiner":"Shipped a stateless FastAPI raster-to-vector engine with OpenCV preprocessing, dual vectorization modes (Potrace + VTracer), RDP post-processing with island detection, three output formats (SVG, DXF, JSON), a 5-preset configuration system, and Docker packaging — 196 tests passing.","requirementOutcomes":"No formal requirements (REQUIREMENTS.md) were defined for this milestone.

Engine is the hardest and most valuable piece. | No | human |\n| D003 | | engine | Post-processing replaces regex metadata extraction | postprocess_svg() pipeline replaces old _extract_svg_metadata() regex approach; all SVG paths are parsed into structured PathInfo objects with coordinates, area, island status | Structured path data is needed for DXF/JSON output generation, RDP simplification, and island detection. XML parsing is now necessary since we need actual coordinate data, not just counts. This supersedes D003's regex approach. | No | agent |\n| D004 | | architecture | Engine Docker image build strategy | Multi-stage build: builder stage compiles pypotrace with build-essential/libagg-dev/libpotrace-dev, runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl).

After you finish, a **planner agent** reads your output in a fresh context with no memory of your exploration. It uses your findings to decompose this slice into executable tasks — deciding what files change, what order to build things, how to verify the work. Then **executor agents** build each task in isolated context windows.\n\nWrite for the planner, not for a human. The planner needs:\n- **What files exist and what they do** — so it can scope tasks to specific files\n- **Where the natural seams are** — where work divides into independent units\n- **What to build or prove first** — what's riskiest, what unblocks everything else\n- **How to verify the result** — what commands, tests, or checks confirm the slice works\n\nIf the research doc is vague, the planner will waste its context re-exploring code you already read. If it's precise, the planner can decompose immediately.\n\n## Calibrate Depth\n\nRead the slice title, the roadmap excerpt, and any milestone research above. Ask: does this slice involve unfamiliar technology, risky integration, novel architecture, or ambiguous requirements? Or is it straightforward application of known patterns to known code?\n\n- **Deep research** — new technology, unfamiliar APIs, risky integration, multiple viable approaches, or ambiguous scope. Explore broadly, look up docs, check libraries, investigate constraints. Write all template sections. This is the default when you're genuinely uncertain.\n- **Targeted research** — known technology but new to this codebase, or moderately complex integration. Explore the relevant code, check one or two libraries, identify constraints. Omit Don't Hand-Roll and Sources if nothing applies.\n- **Light research** — well-understood work using established patterns already in the codebase (wiring up existing APIs, adding standard UI components, CRUD operations, configuration changes). Read the relevant files to confirm the pattern, note any constraints, write Summary + Recommendation + Implementation Landscape. Skip the rest. A light research doc can be 15-20 lines. Don't manufacture pitfalls or risks for work that doesn't have them.\n\nAn honest \"this is straightforward, here's the pattern to follow\" is more valuable than invented complexity.\n\n## Steps\n\nResearch what this slice needs. Narrate key findings and surprises as you go — what exists, what's missing, what constrains the approach.\n0. If `REQUIREMENTS.md` was preloaded above, identify which Active requirements this slice owns or supports. Research should target these requirements — surfacing risks, unknowns, and implementation constraints that could affect whether the slice actually delivers them.\n1. Reference specific rules from loaded skills in your findings where they inform the implementation approach.\n2. **Skill Discovery (suggest):**\n Identify the key technologies, frameworks, and services this work depends on (e.g. Stripe, Clerk, Supabase, JUCE, SwiftUI).\n For each, check if a professional agent skill already exists:\n - First check `` in your system prompt — a skill may already be installed.\n - For technologies without an installed skill, run: `npx skills find \"\"`\n - Only consider skills that are **directly relevant** to core technologies — not tangentially related.\n - Evaluate results by install count and relevance to the actual work.\n - Note promising skills in your research output with their install commands, but do NOT install them.\n - The user will decide which to install.\n3. Explore relevant code for this slice's scope. For targeted exploration, use `rg`, `find`, and reads. For broad or unfamiliar subsystems, use `scout` to map the relevant area first.\n4. Use `resolve_library` / `get_library_docs` for unfamiliar libraries — skip this for libraries already used in the codebase\n5. **Web search budget:** You have a limited budget of web searches (max ~15 per session). Use them strategically — prefer `resolve_library` / `get_library_docs` for library documentation. Do NOT repeat the same or similar queries. If a search didn't find what you need, rephrase once or move on. Target 3-5 total web searches for a typical research unit.\n6. Use the **Research** output template from the inlined context above — include only sections that have real content. The template is already inlined above; do NOT attempt to read any template file from disk (there is no `templates/SLICE-RESEARCH.md` — the correct template is already present in this prompt).\n7. Call `gsd_summary_save` with `milestone_id: M002`, `slice_id: S01`, `artifact_type: \"RESEARCH\"`, and the full research markdown as `content` — the tool computes the file path and persists to both DB and disk.\n\nThe slice directory already exists at `.gsd/milestones/M002/slices/S01/`. Do NOT mkdir.\n\n**You MUST call `gsd_summary_save` with the research content before finishing.**\n\nWhen done, say: \"Slice S01 researched.\"","display":false,"id":"22829733","parentId":"a48342bf","timestamp":"2026-03-26T04:57:16.227Z"} +{"type":"message","id":"8f01b111","parentId":"22829733","timestamp":"2026-03-26T04:57:22.123Z","message":{"role":"assistant","content":[{"type":"text","text":"\n\nI'll research Slice S01 (\"Import & Convert UI (View 1)\") for Milestone M002.

Kerf — Project Brief\n \n**Working Directory:** `/vmPool/r/repos/xpltdco/kerf`\n**Deployment Target:** Docker container (self-hostable or cloud-hosted)\n**Primary Use Case:** Raster-to-vector conversion engine + 2D sign/patch design canvas + DXF export workflow\n \n---\n \n## Vision\n \nKerf is a modular, Docker-deployed web application with two distinct but composable layers:\n \n1. **The Kerf Engine** — a standalone, API-first raster-to-vector conversion module. This is proprietary IP. It must be built with clean, well-documented input/output contracts so it can be extracted and embedded into future applications independently of this one.\n \n2. **The Kerf App** — a full-featured 2D design canvas and sign configuration workflow that consumes the Kerf Engine and delivers a complete end-to-end experience: upload an image or design from scratch, refine the vector output, compose a sign layout, and download a production-ready DXF file.\n \nThe two layers must remain architecturally decoupled. The Engine is not a feature of the App — the App is a consumer of the Engine.\n \n---\n \n## Repository Structure\n \n```\n/vmPool/r/repos/xpltdco/kerf/\n /engine/ ← Kerf Engine (standalone module, own package.json / pyproject)\n /app/ ← Kerf App frontend (React)\n /server/ ← Kerf App backend API (Python/FastAPI)\n /docker/ ← Dockerfiles and compose configs\n /docs/ ← Engine API docs, architecture notes\n README.md\n docker-compose.yml\n```\n \n---\n \n## Part 1: The Kerf Engine\n \n### What It Is\n \nA self-contained service that accepts raster image input and returns clean vector output. It also accepts existing vector input (SVG) for simplification passes. This is the hardest, most valuable piece of the entire project. Build and validate this first before touching the app canvas.\n \n### Processing Pipeline\n \nThe engine runs a multi-stage pipeline internally:\n \n```\nInput (raster or vector)\n → Preprocessing (OpenCV)\n → Vectorization (Potrace or VTracer, mode-dependent)\n → Post-processing (path simplification, cleanup)\n → Output (SVG, DXF, or JSON path data)\n```\n \n#### Stage 1 — Preprocessing (raster inputs only)\nUses OpenCV. The following operations are applied in sequence, each tunable via parameters:\n- Grayscale conversion\n- Denoise (bilateral filter — preserves edges better than Gaussian for this use case)\n- Contrast enhancement (CLAHE — adaptive histogram equalization)\n- Threshold (Otsu auto-threshold as default, manual override available)\n- Edge detection mode (optional — Canny, for line-art inputs)\n- Dilation/erosion (for cleaning up noisy inputs before tracing)\n \n#### Stage 2 — Vectorization\nTwo modes, selectable per request:\n \n**Mode A: Potrace** (default)\n- Fast, deterministic, excellent for high-contrast logos and line art\n- Exposes Potrace tuning parameters: `turdsize`, `alphamax`, `opticurve`, `opttolerance`\n- Best for: clean logos, stencils, bold graphics, sign art\n \n**Mode B: VTracer**\n- Better handling of photographic or noisy inputs, color-aware\n- Exposes VTracer params: `colormode`, `hierarchical`, `filter_speckle`, `color_precision`, `layer_difference`, `corner_threshold`, `length_threshold`, `splice_threshold`\n- Best for: complex images, multi-color inputs, detailed illustrations\n \nThe engine selects Mode A by default. The calling application (or user via preset) can override.\n \n#### Stage 3 — Post-Processing\n- **Path simplification:** Ramer-Douglas-Peucker algorithm, `epsilon` tunable. Also applies to vector-only inputs (simplification-only mode).\n- **Island detection:** Identify and flag interior counter paths (letter holes, enclosed shapes) for proper nesting in DXF output\n- **Open path detection and repair:** Flag or auto-close open endpoints\n- **Node count reporting:** Return node count per path so the UI can warn the user if complexity is too high for practical cutting\n \n#### Stage 4 — Output\nSupported output formats:\n- `SVG` — standard, browser-renderable\n- `DXF` — AC1015+ (AutoCAD 2000 compatible), via makerjs or direct entity generation\n- `JSON` — raw path data (array of bezier/polyline commands) for consuming applications to render or further process\n \nAll outputs include metadata:\n```json\n{\n \"format\": \"svg\",\n \"path_count\": 12,\n \"node_count_total\": 847,\n \"open_paths\": 0,\n \"warnings\": [\"High node count — consider increasing simplification\"],\n \"processing_ms\": 340\n}\n```\n \n---\n \n### Engine API Contract\n \nThe Engine exposes a clean HTTP API. This is the stable interface other applications will consume.\n \n#### `POST /engine/trace`\nTrace a raster image to vector.\n \n**Request:** `multipart/form-data`\n```\nfile — image file (PNG, JPG, BMP, TIFF, WebP)\nmode — \"potrace\" | \"vtracer\" (default: potrace)\noutput_format — \"svg\" | \"dxf\" | \"json\" (default: svg)\npreset — \"sign\" | \"patch\" | \"stencil\" | \"detailed\" | \"custom\" (default: sign)\nparams — JSON string of override parameters (optional, merges over preset defaults)\n```\n \n**Response:** `application/json`\n```json\n{\n \"output\": \"...\",\n \"format\": \"svg\",\n \"metadata\": { ... }\n}\n```\n \n#### `POST /engine/simplify`\nSimplify an existing SVG vector.\n \n**Request:** `multipart/form-data`\n```\nfile — SVG file\nepsilon — float, RDP simplification tolerance (default: 1.0)\noutput_format — \"svg\" | \"dxf\" | \"json\"\n```\n \n**Response:** same shape as `/engine/trace`\n \n#### `GET /engine/presets`\nReturns the full list of available presets and their parameter values.\n \n---\n \n### Presets\n \nPresets are named configurations that set all tuning parameters to sensible defaults for a given application. Users pick a preset first, then fine-tune from there.\n \n| Preset | Description | Key Biases |\n|---|---|---|\n| `sign` | Metal signage, bold text cutouts | High contrast, aggressive simplification, low node count |\n| `patch` | Embroidered patches, fabric cutting | Medium detail, smooth curves, closed paths enforced |\n| `stencil` | Physical stencil cutting | Simplified, bridges flagged, no islands |\n| `detailed` | High-fidelity illustration work | Low simplification, maximum path fidelity |\n| `custom` | All params exposed, no defaults applied | — |\n \nPresets are stored as JSON config files in `/engine/presets/` so new ones can be added without code changes.\n \n---\n \n### Engine Testing Checkpoint\n \n**Stop here and validate the engine before building anything else.**\n \nPrompt the human to:\n1. Submit a clean high-contrast PNG logo via the API and confirm the SVG output renders correctly in a browser\n2. Submit the same image in `dxf` output mode and open the result in Inkscape or LightBurn — confirm paths are closed and geometry is clean\n3. Submit a noisy or photographic input and compare Mode A vs Mode B output\n4. Submit an existing complex SVG and run it through `/engine/simplify` — confirm node count drops and shape is preserved\n5. Test each preset and confirm the outputs differ meaningfully\n \n**Do not proceed to the App canvas until the human explicitly signs off on engine output quality.**\n \n---\n \n## Part 2: The Kerf App\n \n### Overview\n \nA React-based single-page application served by a FastAPI backend. Deployed as a Docker container. Functions both as a standalone web app (direct URL access) and as an embeddable component (script tag + div).\n \nThe App is composed of three views that function as a linear workflow with the ability to jump back:\n \n```\n[1. Import & Convert] → [2. Design Canvas] → [3. Export]\n```\n \n---\n \n### View 1: Import & Convert\n \nThis is the Kerf Engine's UI surface. The user arrives here first.\n \n#### Import Options\n- **Upload raster image** (PNG, JPG, BMP, TIFF, WebP) — primary flow\n- **Upload existing vector** (SVG) — routes to simplification mode\n- **Start blank** — skip import, go directly to canvas with empty artboard\n \n#### Vectorization Controls (shown after upload)\nLayout: image preview on the left, controls on the right, live output preview updates as controls change.\n \n**Preset Selector**\n- Visual cards for each preset (icon + label + one-line description)\n- Selecting a preset populates all sliders with preset defaults\n- User can then adjust individual sliders freely\n \n**Control Sliders / Toggles**\nAll controls update the preview in real time (debounced, ~300ms):\n \n| Control | Type | Description |\n|---|---|---|\n| Detail Level | Slider | Master control — maps to simplification epsilon. Low = more detail, High = simpler paths |\n| Threshold | Slider | Black/white cutoff for rasterized input preprocessing |\n| Noise Filter | Slider | Speckle/noise removal aggressiveness |\n| Smooth Curves | Slider | Curve fitting vs sharp corners |\n| Path Mode | Toggle | Outline only vs filled regions |\n| Color Mode | Toggle (VTracer only) | B&W vs color-aware tracing |\n| Advanced | Expandable panel | Exposes all raw Potrace/VTracer parameters for power users |\n \n**Output Info Bar**\nBelow the preview — shows live stats: path count, total node count, open path warnings, estimated file size. Color-coded: green (good), yellow (high complexity warning), red (open paths or unusable geometry detected).\n \n**Action Buttons**\n- \"Use This\" — accepts current output and advances to the Design Canvas, carrying the vector data forward\n- \"Re-import\" — start over with a new file\n \n---\n \n### View 2: Design Canvas\n \nA 2D design environment. Think Illustrator-lite meets a CNC layout tool. Built with **Konva.js + React** (react-konva).\n \n#### Artboard Setup\nOn first entering the canvas (or when starting blank), the user defines their artboard:\n \n**Shape:**\n- Rectangle\n- Square\n- Circle\n- Oval/Ellipse\n- Shield (common patch shape)\n- Pennant\n- Custom (width + height freeform)\n \n**Dimensions:**\n- Width and Height inputs (inches)\n- Units toggle: inches / mm\n- The artboard renders at a scaled representation — 1:1 real-world proportion maintained\n \n#### Canvas Objects\n \nAll objects are layered, selectable, moveable, resizable, and deletable. Standard selection handles. Multi-select supported.\n \n**Text Objects**\n- Add text via toolbar button\n- Font picker — reads from `/fonts/fonts.json` manifest (same pattern as the sign component: local `.otf` files, dynamic manifest, per-font warning flags)\n- Font size, letter spacing, line height\n- Alignment: left, center, right\n- Text renders using opentype.js for accurate glyph representation\n- Toggle: \"Convert to paths\" — flattens text to vector paths for export (required for DXF)\n \n**Imported Vector Object**\n- The output from View 1 drops onto the canvas as a vector object\n- Fully moveable, scaleable, rotatable\n- Can be duplicated\n \n**Basic Shape Objects**\n- Rectangle / Square\n- Circle / Ellipse\n- Line — with style variants:\n - Solid\n - Dashed (configurable dash/gap length)\n - Dotted\n - Double line\n - Centerline (long-short-long pattern, common in CAD)\n- Stroke weight control\n- Fill toggle (filled vs outline only)\n \n**Object Panel**\nRight sidebar showing layer stack — all objects listed, reorderable via drag, visibility toggle per object, lock toggle per object.\n \n#### Canvas Toolbar\nTop bar with:\n- Select tool\n- Text tool\n- Shape tools (rectangle, circle, line)\n- Zoom in / out / fit to screen\n- Undo / Redo (full history stack)\n- Grid toggle (snap to grid, configurable grid size)\n- Rulers toggle\n \n#### Alignment Tools\nWhen one or more objects are selected:\n- Align left / center / right (relative to artboard or to selection)\n- Align top / middle / bottom\n- Distribute horizontally / vertically\n- Center on artboard (single click to center both axes)\n \n---\n \n### View 3: Export\n \nClean, focused export screen.

POST /engine/trace accepts PNG uploads and returns SVG output with metadata. 76 tests established the foundation and patterns (programmatic test images via numpy, .venv pytest runner).\n\n**S02 (Post-Processing + Output Formats)** added the post-processing layer that parses raw SVG paths into structured PathInfo objects, implements Ramer-Douglas-Peucker simplification, detects islands via signed-area calculation, and identifies open paths. Three output generators consume PostProcessResult: DXF (AC1015 with LWPOLYLINE entities, islands on separate layer), JSON (structured path commands with properties), and SVG (simplified output). A /engine/simplify endpoint was added for SVG-to-SVG/DXF/JSON conversion. The old regex-based metadata extraction was replaced entirely by full path parsing — a necessary evolution to support DXF coordinate output and island detection.\n\n**S03 (Presets + Docker)** wrapped the milestone with a preset system (5 tuned configs: sign, patch, stencil, detailed, custom) that drives the entire pipeline via merge-based param resolution (preset defaults + user overrides). GET /engine/presets exposes all configs. Docker packaging uses a multi-stage build — builder stage compiles pypotrace with C dependencies, runtime stage uses python:3.11-slim with only engine source (no App code), enforcing the Engine/App separation mandated by D001.

The engine API is fully built and validated (M001, 196 tests) — this slice is a pure frontend build that consumes it.\n\nThe work is greenfield — no `app/` directory, no `package.json`, no frontend tooling exists. The slice must scaffold a React + Vite + TypeScript project, establish the app shell with view routing, build the file upload flow, integrate with the Engine API's `multipart/form-data` endpoints, implement debounced re-tracing on parameter changes, and render SVG previews. A secondary prerequisite is adding CORS middleware to the engine so browser requests succeed.\n\nThe approach is straightforward: Vite + React + TypeScript scaffold, Zustand or simple React state for view-level state, raw `fetch` + `FormData` for engine API calls (no need for a heavy HTTP client), and inline SVG rendering via `dangerouslySetInnerHTML` for the preview. The primary risks are the debounced preview update loop (must cancel in-flight requests on param change) and correctly mapping UI slider values to the engine's nested parameter structure.\n\n## Recommendation\n\nScaffold `app/` as a Vite + React + TypeScript project. Keep dependencies minimal — no UI framework needed for V1 (plain CSS or CSS modules). Use a simple view router (React Router or even a state-based conditional render since there are only 3 views). Build the engine API client as a thin typed wrapper around `fetch`. For the live preview loop, use an `AbortController`-based pattern: each parameter change triggers a debounced (300ms) re-trace call that aborts any in-flight request first. Add CORS to the engine's `main.py` as a prerequisite task.\n\n## Implementation Landscape\n\n### Key Files\n\n**Engine (existing — read-only context for this slice):**\n- `engine/main.py` — FastAPI app; needs `CORSMiddleware` added (only change to engine code)\n- `engine/api/routes.py` — Defines `POST /engine/trace` (multipart: file, mode, output_format, preset, params), `POST /engine/simplify`, `GET /engine/presets`\n- `engine/presets/*.json` — 5 preset configs (sign, patch, stencil, detailed, custom); each has `preprocessing`, `vectorization`, and `postprocessing` sections\n\n**App (to be created):**\n- `app/package.json` — Vite + React + TypeScript deps\n- `app/vite.config.ts` — Dev server config with proxy to engine API (avoids CORS in dev, but CORS still needed for production)\n- `app/src/main.tsx` — React root mount\n- `app/src/App.tsx` — Top-level view router (View 1 → View 2 → View 3)\n- `app/src/views/ImportConvert.tsx` — Main View 1 component\n- `app/src/components/FileUpload.tsx` — Drag-and-drop file upload zone\n- `app/src/components/PresetSelector.tsx` — Visual preset cards (icon + label + description)\n- `app/src/components/ParameterSliders.tsx` — Slider controls mapped to engine params\n- `app/src/components/SvgPreview.tsx` — Live SVG render panel\n- `app/src/components/OutputInfoBar.tsx` — Stats bar (path count, node count, warnings) with color coding\n- `app/src/api/engine.ts` — Typed API client: `traceImage()`, `getPresets()`, `simplifyVector()`\n- `app/src/types/engine.ts` — TypeScript types for API request/response shapes, preset configs\n\n### Build Order\n\n1. **CORS on engine** — add `CORSMiddleware` to `engine/main.py`. Without this, no browser-based API call works. Quick, unblocks everything. Verify: `curl -H \"Origin: http://localhost:5173\" -I http://localhost:8000/engine/health` returns CORS headers.\n\n2. **Vite + React scaffold** — `npm create vite@latest app -- --template react-ts`, install deps, configure dev proxy. Verify: `npm run dev` shows a React page at `localhost:5173`.\n\n3. **API client + types** — Build `engine.ts` with typed `traceImage()` and `getPresets()` functions. Uses `FormData` for trace (the engine expects `multipart/form-data`), returns parsed JSON with typed `TraceResponse` interface. Verify: import and call `getPresets()` from a useEffect, log to console.\n\n4. **View shell + routing** — App.tsx with view state (import → canvas → export). Only View 1 active for this slice; View 2/3 are placeholder divs. The \"Use This\" button sets view state + passes vector data forward. Verify: view switching works on button click.\n\n5. **File upload component** — Drag-and-drop zone + file input fallback. Accepts PNG, JPG, BMP, TIFF, WebP for raster; SVG for simplification mode. Shows filename + thumbnail after selection. Verify: selecting a file shows preview.\n\n6. **Preset selector + parameter sliders** — Fetch presets from `GET /engine/presets` on mount. Render preset cards. When preset selected, populate slider values from preset defaults. Sliders: Detail Level (epsilon), Threshold, Noise Filter, Smooth Curves, plus an Advanced panel that exposes raw params. Verify: selecting different presets changes slider positions.\n\n7. **Live preview with debounced re-trace** — Core interaction loop. On any parameter change: debounce 300ms → build FormData with file + current params → `POST /engine/trace` → render returned SVG. Use `AbortController` to cancel in-flight request if params change again. Verify: change a slider, see SVG preview update after debounce.\n\n8. **Output info bar** — Render metadata from trace response: path count, total node count, open path count, warnings. Color code: green (good), yellow (high node count), red (open paths). Verify: info bar updates with each trace response.\n\n### Verification Approach\n\n- `cd app && npm run dev` starts Vite dev server at `localhost:5173`\n- Engine must be running at `localhost:8000` (either via docker or `cd engine && .venv/bin/uvicorn main:app --port 8000`)\n- Upload a PNG image → preset selector appears → select \"sign\" → sliders populate → SVG preview renders\n- Change epsilon slider → preview updates within ~500ms (300ms debounce + API latency)\n- Switch to \"detailed\" preset → sliders change → preview updates with higher detail\n- Info bar shows path count, node count, open paths — values change per preset\n- Click \"Use This\" → view state transitions (placeholder View 2 renders)\n- Upload an SVG file → routes to simplification mode (only epsilon slider, no preprocessing/vectorization controls)\n\n## Constraints\n\n- **Engine API uses `multipart/form-data`** — cannot POST JSON. Must construct `FormData` with `file` field (Blob/File) and string fields for `mode`, `output_format`, `preset`, `params` (JSON-encoded string).\n- **`params` field is a JSON string** — nested parameter overrides are sent as a serialized JSON string in the form data, not as separate form fields. The engine's `resolve_params()` merges these over preset defaults.\n- **SVG preview is a raw string** — the engine returns SVG as a string in `response.output`. Rendering it requires either `dangerouslySetInnerHTML` or creating an `` tag. The former preserves interactivity/scalability.\n- **No `python` on system PATH** — engine must run via `.venv/bin/uvicorn` or Docker. Dev workflow needs both processes (engine + vite) running simultaneously.\n- **Engine has no CORS** — `engine/main.py` needs `CORSMiddleware` from `fastapi.middleware.cors` added before any browser-based testing works.\n\n## Common Pitfalls\n\n- **Stale previews from race conditions** — If the user changes params rapidly, multiple `/engine/trace` requests fire. The response from an older request may arrive after a newer one, showing stale output. Fix: use `AbortController` — abort previous request before sending a new one, and/or track a request generation counter and discard responses from older generations.\n- **SVG viewBox scaling** — Engine-generated SVGs have their own `width`, `height`, and `viewBox`. The preview panel must scale the SVG to fit its container while preserving aspect ratio. Stripping `width`/`height` attributes and relying on `viewBox` + CSS `width: 100%; height: auto` is the standard approach.\n- **File reference lost after first trace** — The `File` object from the upload input must be retained in state across re-traces. Each debounced trace call rebuilds `FormData` with the same file. Don't re-read the file from the input element — store it in React state.\n- **Advanced panel param names must match engine expectations** — The `params` JSON keys must exactly match what `resolve_params()` looks for (e.g., `turdsize`, `alphamax`, `epsilon`, `filter_speckle`). Typos silently ignored.\n\n## Don't Hand-Roll\n\n| Problem | Existing Solution | Why Use It |\n|---------|------------------|------------|\n| Project scaffold | `npm create vite@latest -- --template react-ts` | Standard React + TS + Vite in one command |\n| Debounce | `setTimeout`/`clearTimeout` pattern or a tiny `useDebouncedCallback` hook | Simple enough to hand-roll as a 10-line hook; no need for lodash |\n| Request cancellation | `AbortController` (native browser API) | Built-in, no library needed |\n| SVG rendering | `dangerouslySetInnerHTML` on a container div | The SVG is trusted (comes from our engine), so XSS concern is minimal |\n\n## Open Risks\n\n- **Engine latency on large images** — If tracing takes >2s for a large image, the live preview UX degrades. May need a loading spinner overlay on the preview during re-trace. Not a blocker but affects polish.\n- **SVG simplification mode routing** — When user uploads an SVG instead of a raster, the UI should switch to a reduced control set (only epsilon slider, no preprocessing/vectorization). This is a separate code path that needs clean conditional rendering.\n\n## Skills Discovered\n\n| Technology | Skill | Status |\n|------------|-------|--------|\n| React | `react-best-practices` | installed (available in skill list) |\n| Vite | `antfu/skills@vite` (11.5K installs) | available — not installed |\n\n## Sources\n\n- Engine API contract: `engine/api/routes.py` (read directly)\n- Preset structure: `engine/presets/*.json` (read directly)\n- Project brief: `GSD-INITIATE.md` View 1 specification (read directly)\n","milestone_id":"M002","slice_id":"S01"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":3207,"cacheRead":75041,"cacheWrite":128,"totalTokens":78377,"cost":{"input":0.000005,"output":0.08017500000000001,"cacheRead":0.0375205,"cacheWrite":0.0008,"total":0.11850050000000001}},"stopReason":"toolUse","timestamp":1774501101251}} +{"type":"message","id":"a660b4c0","parentId":"96a0d28c","timestamp":"2026-03-26T04:59:40.778Z","message":{"role":"toolResult","toolCallId":"toolu_01Ag81ANTU5cBdFFGVYVo1jU","toolName":"gsd_summary_save","content":[{"type":"text","text":"Saved RESEARCH artifact to milestones/M002/slices/S01/S01-RESEARCH.md"}],"details":{"operation":"save_summary","path":"milestones/M002/slices/S01/S01-RESEARCH.md","artifact_type":"RESEARCH"},"isError":false,"timestamp":1774501180777}} +{"type":"message","id":"ad198e14","parentId":"a660b4c0","timestamp":"2026-03-26T04:59:42.686Z","message":{"role":"assistant","content":[{"type":"text","text":"Slice S01 researched."}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":11,"cacheRead":75169,"cacheWrite":3245,"totalTokens":78426,"cost":{"input":0.000005,"output":0.000275,"cacheRead":0.0375845,"cacheWrite":0.02028125,"total":0.05814575}},"stopReason":"stop","timestamp":1774501180777}} diff --git a/.gsd/activity/018-plan-slice-M002-S01.jsonl b/.gsd/activity/018-plan-slice-M002-S01.jsonl new file mode 100644 index 0000000..edbcf85 --- /dev/null +++ b/.gsd/activity/018-plan-slice-M002-S01.jsonl @@ -0,0 +1,31 @@ +{"type":"thinking_level_change","id":"b554909e","parentId":null,"timestamp":"2026-03-26T04:59:42.960Z","thinkingLevel":"off"} +{"type":"custom_message","customType":"gsd-auto","content":"You are executing GSD auto-mode.\n\n## Working Directory\n\nYour working directory is `/home/aux/development/xpltdco/kerf-engine`.

Do NOT `cd` to any other directory.\n\nAll relevant context has been preloaded below — start working immediately without re-reading these files.\n\n## Executor Context Constraints\n\nThe agent that executes each task has a **200K token** context window.\n- Recommended task count for this slice: **2–6 tasks**\n- Each task gets ~320K chars of inline context (plans, code, decisions)\n- Keep individual tasks completable within a single context window — if a task needs more context than fits, split it\n\nThen:\n0. If `REQUIREMENTS.md` was preloaded above, identify which Active requirements the roadmap says this slice owns or supports. These are the requirements this plan must deliver — every owned requirement needs at least one task that directly advances it, and verification must prove the requirement is met.\n1. Read the templates:\n - `~/.gsd/agent/extensions/gsd/templates/plan.md`\n - `~/.gsd/agent/extensions/gsd/templates/task-plan.md`\n2. Record the installed skills you expect executors to use in each task plan's `skills_used` frontmatter.\n3. Define slice-level verification — the objective stopping condition for this slice:\n - For non-trivial slices: plan actual test files with real assertions. Name the files.\n - For simple slices: executable commands or script assertions are fine.\n - If the project is non-trivial and has no test framework, the first task should set one up.\n - If this slice establishes a boundary contract, verification must exercise that contract.\n4. **For non-trivial slices only** — plan observability, proof level, and integration closure:\n - Include `Observability / Diagnostics` for backend, integration, async, stateful, or UI slices where failure diagnosis matters.\n - Fill `Proof Level` and `Integration Closure` when the slice crosses runtime boundaries or has meaningful integration concerns.\n - **Omit these sections entirely for simple slices** where they would all be \"none\" or trivially obvious.\n5. Decompose the slice into tasks, each fitting one context window. Each task needs:\n - a concrete, action-oriented title\n - the inline task entry fields defined in the plan.md template (Why / Files / Do / Verify / Done when)\n - a matching task plan file with description, steps, must-haves, verification, inputs, and expected output\n - **Inputs and Expected Output must list concrete backtick-wrapped file paths** (e.g. `` `src/types.ts` ``). These are machine-parsed to derive task dependencies — vague prose without paths breaks parallel execution. Every task must have at least one output file path.\n - Observability Impact section **only if the task touches runtime boundaries, async flows, or error paths** — omit it otherwise\n6. **Persist planning state through `gsd_plan_slice`.** Call it with the full slice planning payload (goal, demo, must-haves, verification, tasks, and metadata). The tool inserts all tasks in the same transaction, writes to the DB, and renders `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/S01-PLAN.md` and `.gsd/milestones/M002/slices/S01/tasks/T##-PLAN.md` files automatically. Do **not** call `gsd_plan_task` separately — `gsd_plan_slice` handles task persistence. Do **not** rely on direct `PLAN.md` writes as the source of truth; the DB-backed tool is the canonical write path for slice and task planning state.\n7. **Self-audit the plan.** Walk through each check — if any fail, fix the plan files before moving on:\n - **Completion semantics:** If every task were completed exactly as written, the slice goal/demo should actually be true.\n - **Requirement coverage:** Every must-have in the slice maps to at least one task. No must-have is orphaned. If `REQUIREMENTS.md` exists, every Active requirement this slice owns maps to at least one task.\n - **Task completeness:** Every task has steps, must-haves, verification, inputs, and expected output — none are blank or vague. Inputs and Expected Output list backtick-wrapped file paths, not prose descriptions.\n - **Dependency correctness:** Task ordering is consistent. No task references work from a later task.\n - **Key links planned:** For every pair of artifacts that must connect, there is an explicit step that wires them.\n - **Scope sanity:** Target 2–5 steps and 3–8 files per task. 10+ steps or 12+ files — must split. Each task must be completable in a single fresh context window.\n - **Feature completeness:** Every task produces real, user-facing progress — not just internal scaffolding.\n10. If planning produced structural decisions, append them to `.gsd/DECISIONS.md`\n11. Do not commit — .gsd/ planning docs are managed externally and not tracked in git.\n\nThe slice directory and tasks/ subdirectory already exist. Do NOT mkdir. All work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_plan_slice` to persist the planning state before finishing.**\n\nWhen done, say: \"Slice S01 planned.\"\n## UNIT: Plan Slice S01 (\"Import & Convert UI (View 1)\") — Milestone M002\n\n## Inlined Context (preloaded — do not re-read these files)\n\n### Milestone Roadmap\nSource: `.gsd/milestones/M002/M002-ROADMAP.md`\n\n# M002: \n\n## Vision\nBuild the React frontend with the Import & Convert view (View 1) and the Design Canvas (View 2). View 1 integrates with the Engine API for vectorization with live preview.

The engine API is fully built and validated (M001, 196 tests) — this slice is a pure frontend build that consumes it.\n\nThe work is greenfield — no `app/` directory, no `package.json`, no frontend tooling exists. The slice must scaffold a React + Vite + TypeScript project, establish the app shell with view routing, build the file upload flow, integrate with the Engine API's `multipart/form-data` endpoints, implement debounced re-tracing on parameter changes, and render SVG previews. A secondary prerequisite is adding CORS middleware to the engine so browser requests succeed.\n\nThe approach is straightforward: Vite + React + TypeScript scaffold, Zustand or simple React state for view-level state, raw `fetch` + `FormData` for engine API calls (no need for a heavy HTTP client), and inline SVG rendering via `dangerouslySetInnerHTML` for the preview. The primary risks are the debounced preview update loop (must cancel in-flight requests on param change) and correctly mapping UI slider values to the engine's nested parameter structure.\n\n## Recommendation\n\nScaffold `app/` as a Vite + React + TypeScript project. Keep dependencies minimal — no UI framework needed for V1 (plain CSS or CSS modules). Use a simple view router (React Router or even a state-based conditional render since there are only 3 views). Build the engine API client as a thin typed wrapper around `fetch`. For the live preview loop, use an `AbortController`-based pattern: each parameter change triggers a debounced (300ms) re-trace call that aborts any in-flight request first. Add CORS to the engine's `main.py` as a prerequisite task.\n\n## Implementation Landscape\n\n### Key Files\n\n**Engine (existing — read-only context for this slice):**\n- `engine/main.py` — FastAPI app; needs `CORSMiddleware` added (only change to engine code)\n- `engine/api/routes.py` — Defines `POST /engine/trace` (multipart: file, mode, output_format, preset, params), `POST /engine/simplify`, `GET /engine/presets`\n- `engine/presets/*.json` — 5 preset configs (sign, patch, stencil, detailed, custom); each has `preprocessing`, `vectorization`, and `postprocessing` sections\n\n**App (to be created):**\n- `app/package.json` — Vite + React + TypeScript deps\n- `app/vite.config.ts` — Dev server config with proxy to engine API (avoids CORS in dev, but CORS still needed for production)\n- `app/src/main.tsx` — React root mount\n- `app/src/App.tsx` — Top-level view router (View 1 → View 2 → View 3)\n- `app/src/views/ImportConvert.tsx` — Main View 1 component\n- `app/src/components/FileUpload.tsx` — Drag-and-drop file upload zone\n- `app/src/components/PresetSelector.tsx` — Visual preset cards (icon + label + description)\n- `app/src/components/ParameterSliders.tsx` — Slider controls mapped to engine params\n- `app/src/components/SvgPreview.tsx` — Live SVG render panel\n- `app/src/components/OutputInfoBar.tsx` — Stats bar (path count, node count, warnings) with color coding\n- `app/src/api/engine.ts` — Typed API client: `traceImage()`, `getPresets()`, `simplifyVector()`\n- `app/src/types/engine.ts` — TypeScript types for API request/response shapes, preset configs\n\n### Build Order\n\n1. **CORS on engine** — add `CORSMiddleware` to `engine/main.py`. Without this, no browser-based API call works. Quick, unblocks everything. Verify: `curl -H \"Origin: http://localhost:5173\" -I http://localhost:8000/engine/health` returns CORS headers.\n\n2. **Vite + React scaffold** — `npm create vite@latest app -- --template react-ts`, install deps, configure dev proxy. Verify: `npm run dev` shows a React page at `localhost:5173`.\n\n3. **API client + types** — Build `engine.ts` with typed `traceImage()` and `getPresets()` functions. Uses `FormData` for trace (the engine expects `multipart/form-data`), returns parsed JSON with typed `TraceResponse` interface. Verify: import and call `getPresets()` from a useEffect, log to console.\n\n4. **View shell + routing** — App.tsx with view state (import → canvas → export). Only View 1 active for this slice; View 2/3 are placeholder divs. The \"Use This\" button sets view state + passes vector data forward. Verify: view switching works on button click.\n\n5. **File upload component** — Drag-and-drop zone + file input fallback. Accepts PNG, JPG, BMP, TIFF, WebP for raster; SVG for simplification mode. Shows filename + thumbnail after selection. Verify: selecting a file shows preview.\n\n6. **Preset selector + parameter sliders** — Fetch presets from `GET /engine/presets` on mount. Render preset cards. When preset selected, populate slider values from preset defaults. Sliders: Detail Level (epsilon), Threshold, Noise Filter, Smooth Curves, plus an Advanced panel that exposes raw params. Verify: selecting different presets changes slider positions.\n\n7. **Live preview with debounced re-trace** — Core interaction loop. On any parameter change: debounce 300ms → build FormData with file + current params → `POST /engine/trace` → render returned SVG. Use `AbortController` to cancel in-flight request if params change again. Verify: change a slider, see SVG preview update after debounce.\n\n8. **Output info bar** — Render metadata from trace response: path count, total node count, open path count, warnings. Color code: green (good), yellow (high node count), red (open paths). Verify: info bar updates with each trace response.\n\n### Verification Approach\n\n- `cd app && npm run dev` starts Vite dev server at `localhost:5173`\n- Engine must be running at `localhost:8000` (either via docker or `cd engine && .venv/bin/uvicorn main:app --port 8000`)\n- Upload a PNG image → preset selector appears → select \"sign\" → sliders populate → SVG preview renders\n- Change epsilon slider → preview updates within ~500ms (300ms debounce + API latency)\n- Switch to \"detailed\" preset → sliders change → preview updates with higher detail\n- Info bar shows path count, node count, open paths — values change per preset\n- Click \"Use This\" → view state transitions (placeholder View 2 renders)\n- Upload an SVG file → routes to simplification mode (only epsilon slider, no preprocessing/vectorization controls)\n\n## Constraints\n\n- **Engine API uses `multipart/form-data`** — cannot POST JSON.

All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n| L007 | Docker build context must be project root, not engine/ | Dockerfile.engine uses `COPY engine/...` paths relative to project root | Always build with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` from project root | Docker |\n| L008 | Engine container has dual health endpoints | /health on root (main.py) and /engine/health on router (routes.py) both exist | Use /engine/health for Docker HEALTHCHECK and external probes for namespace consistency | engine API, Docker |\n\n---\n\n# {{sliceId}}: {{sliceTitle}}\n\n**Goal:** {{goal}}\n**Demo:** {{demo}}\n\n## Must-Haves\n\n- {{mustHave}}\n- {{mustHave}}\n\n## Proof Level\n\n\n\n- This slice proves: {{contract | integration | operational | final-assembly}}\n- Real runtime required: {{yes/no}}\n- Human/UAT required: {{yes/no}}\n\n## Verification\n\n\n\n- {{testFileOrCommand — e.g. `npm test -- --grep \"auth flow\"` or `bash scripts/verify-s01.sh`}}\n- {{testFileOrCommand}}\n\n## Observability / Diagnostics\n\n\n\n- Runtime signals: {{structured log/event, state transition, metric, or none}}\n- Inspection surfaces: {{status endpoint, CLI command, script, UI state, DB table, or none}}\n- Failure visibility: {{last error, retry count, phase, timestamp, correlation id, or none}}\n- Redaction constraints: {{secret/PII boundary or none}}\n\n## Integration Closure\n\n\n\n- Upstream surfaces consumed: {{specific files / modules / contracts}}\n- New wiring introduced in this slice: {{entrypoint / composition / runtime hookup, or none}}\n- What remains before the milestone is truly usable end-to-end: {{list or \"nothing\"}}\n\n## Tasks\n\n\n\n- [ ] **T01: {{taskTitle}}** `est:{{estimate}}`\n - Why: {{whyThisTaskExists}}\n - Files: `{{filePath}}`, `{{filePath}}`\n - Do: {{specificImplementationStepsAndConstraints}}\n - Verify: {{testCommandOrRuntimeCheck}}\n - Done when: {{measurableAcceptanceCondition}}\n- [ ] **T02: {{taskTitle}}** `est:{{estimate}}`\n - Why: {{whyThisTaskExists}}\n - Files: `{{filePath}}`, `{{filePath}}`\n - Do: {{specificImplementationStepsAndConstraints}}\n - Verify: {{testCommandOrRuntimeCheck}}\n - Done when: {{measurableAcceptanceCondition}}\n\n\n## Files Likely Touched\n\n- `{{filePath}}`\n- `{{filePath}}`\n\n### Output Template: Slice Plan\nSource: `templates/plan.md`\n\n### Dependency Slice Summaries\n\nPay particular attention to **Forward Intelligence** sections — they contain hard-won knowledge about what's fragile, what assumptions changed, and what this slice should watch out for.\n\n- (no dependencies)\n\n## Your Role in the Pipeline\n\nYou have full tool access. Before decomposing, explore the relevant code to ground your plan in reality.\n\n### Verify Roadmap Assumptions\n\nCheck prior slice summaries (inlined above as dependency summaries, if present). If prior slices discovered constraints, changed approaches, or flagged fragility, adjust your plan accordingly. The roadmap description may be stale — verify it against the current codebase state.\n\n### Explore Slice Scope\n\nRead the code files relevant to this slice. Confirm the roadmap's description of what exists, what needs to change, and what boundaries apply. Use `rg`, `find`, and targeted reads.\n\n### Source Files\n\n- **Decisions**: `.gsd/DECISIONS.md`\n- **Roadmap**: `.gsd/milestones/M002/M002-ROADMAP.md`\n- **Slice Research**: `.gsd/milestones/M002/slices/S01/S01-RESEARCH.md`\n\nIf slice research exists (inlined above), trust those findings and skip redundant exploration.\n\nAfter you finish, **executor agents** implement each task in isolated fresh context windows. They see only their task plan, the slice plan excerpt (goal/demo/verification), and compressed summaries of prior tasks. They do not see the research doc, the roadmap, or REQUIREMENTS.md. Everything an executor needs must be in the task plan itself — file paths, specific steps, expected inputs and outputs.\n\nNarrate your decomposition reasoning — why you're grouping work this way, what risks are driving the order, what verification strategy you're choosing and why. Keep the narration proportional to the work — a simple slice doesn't need a long justification — but write in complete sentences, not planner shorthand.\n\n**Right-size the plan.** If the slice is simple enough to be 1 task, plan 1 task. Don't split into multiple tasks just because you can identify sub-steps. Don't fill in sections with \"None\" when the section doesn't apply — omit them entirely. The plan's job is to guide execution, not to fill a template.\n","display":false,"id":"0996daa9","parentId":"b554909e","timestamp":"2026-03-26T04:59:42.962Z"} +{"type":"message","id":"6c56a051","parentId":"0996daa9","timestamp":"2026-03-26T04:59:50.133Z","message":{"role":"assistant","content":[{"type":"text","text":"\n\nI'll start by exploring the current codebase state to ground the plan in reality, then read the templates."},{"type":"toolCall","id":"toolu_01EWRgrgwFEPb2QHNs2Uh9Ge","name":"bash","arguments":{"command":"cd /home/aux/development/xpltdco/kerf-engine && find . -maxdepth 1 -type f -o -type d | head -30 && echo \"---\" && ls -la app/ 2>/dev/null || echo \"No app/ directory\" && echo \"---\" && ls engine/main.py engine/api/routes.py 2>/dev/null"}},{"type":"toolCall","id":"toolu_01AcqYKFYVLUge2YxRQiD4f5","name":"bash","arguments":{"command":"cd /home/aux/development/xpltdco/kerf-engine && cat engine/main.py"}},{"type":"toolCall","id":"toolu_01VUByno4ePqdL7UfSt3SnUW","name":"read","arguments":{"path":"~/.gsd/agent/extensions/gsd/templates/plan.md"}},{"type":"toolCall","id":"toolu_018XTZCSxRFvX4XbZQBpG6nz","name":"read","arguments":{"path":"~/.gsd/agent/extensions/gsd/templates/task-plan.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":2,"output":329,"cacheRead":49688,"cacheWrite":8376,"totalTokens":58395,"cost":{"input":0.00001,"output":0.008225,"cacheRead":0.024843999999999998,"cacheWrite":0.05235,"total":0.085429}},"stopReason":"toolUse","timestamp":1774501182961}} +{"type":"message","id":"3aac9d04","parentId":"6c56a051","timestamp":"2026-03-26T04:59:50.145Z","message":{"role":"toolResult","toolCallId":"toolu_01EWRgrgwFEPb2QHNs2Uh9Ge","toolName":"bash","content":[{"type":"text","text":".\n./.dockerignore\n./.gitignore\n./README.md\n./.git\n./docker\n./REQUIREMENTS.md\n./.gsd\n./engine\n./GSD-INITIATE.md\n./.bg-shell\n./.gsd.lock\n---\nNo app/ directory\n---\nengine/api/routes.py\nengine/main.py\n"}],"isError":false,"timestamp":1774501190145}} +{"type":"message","id":"2e76bd7c","parentId":"3aac9d04","timestamp":"2026-03-26T04:59:50.145Z","message":{"role":"toolResult","toolCallId":"toolu_01AcqYKFYVLUge2YxRQiD4f5","toolName":"bash","content":[{"type":"text","text":"\"\"\"Kerf Engine — raster-to-vector conversion API.\"\"\"\n\nfrom fastapi import FastAPI\n\nfrom api.routes import router\n\napp = FastAPI(\n title=\"Kerf Engine\",\n description=\"Raster-to-vector conversion pipeline with Potrace and VTracer modes\",\n version=\"0.1.0\",\n)\n\napp.include_router(router)\n\n\n@app.get(\"/health\")\nasync def health():\n return {\"status\": \"ok\"}\n"}],"isError":false,"timestamp":1774501190145}} +{"type":"message","id":"2b3f2cac","parentId":"2e76bd7c","timestamp":"2026-03-26T04:59:50.146Z","message":{"role":"toolResult","toolCallId":"toolu_01VUByno4ePqdL7UfSt3SnUW","toolName":"read","content":[{"type":"text","text":"# {{sliceId}}: {{sliceTitle}}\n\n**Goal:** {{goal}}\n**Demo:** {{demo}}\n\n## Must-Haves\n\n- {{mustHave}}\n- {{mustHave}}\n\n## Proof Level\n\n\n\n- This slice proves: {{contract | integration | operational | final-assembly}}\n- Real runtime required: {{yes/no}}\n- Human/UAT required: {{yes/no}}\n\n## Verification\n\n\n\n- {{testFileOrCommand — e.g. `npm test -- --grep \"auth flow\"` or `bash scripts/verify-s01.sh`}}\n- {{testFileOrCommand}}\n\n## Observability / Diagnostics\n\n\n\n- Runtime signals: {{structured log/event, state transition, metric, or none}}\n- Inspection surfaces: {{status endpoint, CLI command, script, UI state, DB table, or none}}\n- Failure visibility: {{last error, retry count, phase, timestamp, correlation id, or none}}\n- Redaction constraints: {{secret/PII boundary or none}}\n\n## Integration Closure\n\n\n\n- Upstream surfaces consumed: {{specific files / modules / contracts}}\n- New wiring introduced in this slice: {{entrypoint / composition / runtime hookup, or none}}\n- What remains before the milestone is truly usable end-to-end: {{list or \"nothing\"}}\n\n## Tasks\n\n\n\n- [ ] **T01: {{taskTitle}}** `est:{{estimate}}`\n -

These are all prerequisites with no user-facing UI on their own, but together they give us a working foundation that can call the engine from the browser.\n\n**T02: App Shell, File Upload, and Preset Selector** — The view routing shell, file upload zone, and preset selector. These are the first user-facing components. Each is straightforward UI with no complex async logic.\n\n**T03: Live SVG Preview with Debounced Re-trace** — The core interaction: parameter sliders, AbortController-based debounced re-trace, SVG rendering. This is the highest-risk piece and gets its own task so the executor can focus.\n\n**T04: Output Info Bar, Polish, and Integration Test** — Stats display, error states, loading indicator, and a Vitest integration test that exercises the full flow at the component level.\n\nLet me also check the `app/` directory doesn't exist and confirm preset structure:"},{"type":"toolCall","id":"toolu_01G3dc5unth5La1crookeam4","name":"bash","arguments":{"command":"cd /home/aux/development/xpltdco/kerf-engine && ls engine/presets/*.json | xargs -I{} bash -c 'echo \"=== {} ===\" && cat {} | python3 -c \"import json,sys; d=json.load(sys.stdin); print(d[\\\"name\\\"], \\\"-\\\", d[\\\"description\\\"])\" 2>/dev/null || echo \"no python3\"'"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":651,"cacheRead":66510,"cacheWrite":618,"totalTokens":67780,"cost":{"input":0.000005,"output":0.016275,"cacheRead":0.033255,"cacheWrite":0.0038625,"total":0.0533975}},"stopReason":"toolUse","timestamp":1774501203160}} +{"type":"message","id":"5f6fd7c0","parentId":"15f8a31d","timestamp":"2026-03-26T05:00:20.833Z","message":{"role":"toolResult","toolCallId":"toolu_01G3dc5unth5La1crookeam4","toolName":"bash","content":[{"type":"text","text":"=== engine/presets/custom.json ===\ncustom - All params exposed, no defaults applied\n=== engine/presets/detailed.json ===\ndetailed - High-fidelity illustration work\n=== engine/presets/patch.json ===\npatch - Embroidered patches, fabric cutting\n=== engine/presets/sign.json ===\nsign - Metal signage, bold text cutouts\n=== engine/presets/stencil.json ===\nstencil - Physical stencil cutting\n"}],"isError":false,"timestamp":1774501220831}} +{"type":"message","id":"c834f34e","parentId":"5f6fd7c0","timestamp":"2026-03-26T05:01:43.595Z","message":{"role":"assistant","content":[{"type":"text","text":"Good.

Add `CORSMiddleware` to `engine/main.py` — import from `fastapi.middleware.cors`, allow all origins for dev (restrict in production later). Place it before the router include.\n2. Scaffold `app/` using `npm create vite@latest app -- --template react-ts`. Run `cd app && npm install`.\n3. Configure `app/vite.config.ts` with a dev proxy: requests to `/engine/*` forward to `http://localhost:8000`.\n4.

Create `app/src/api/engine.ts` with typed functions:\n - `getPresets(): Promise` — calls `GET /engine/presets`\n - `traceImage(file: File, preset: string, params: Record, signal?: AbortSignal): Promise` — builds `FormData` with file, mode, output_format='svg', preset, and params (JSON.stringify), calls `POST /engine/trace`\n - `simplifyVector(file: File, epsilon: number, signal?: AbortSignal): Promise` — calls `POST /engine/simplify`\n6. Remove Vite boilerplate: delete `app/src/App.css`, the counter component content from `App.tsx`, and the Vite/React logos.\n7. Add Vitest as dev dependency: `cd app && npm install -D vitest @testing-library/react @testing-library/jest-dom jsdom`.

Use CSS modules or a single `app/src/views/ImportConvert.module.css`.\n2.

` for 'canvas', placeholder for 'export'\n - Pass a callback `onUseThis(svgOutput: string, metadata: TraceMetadata)` that transitions to 'canvas'\n3. Create `app/src/components/FileUpload.tsx`:\n - Drag-and-drop zone with `onDragOver`/`onDrop` handlers + hidden file `` fallback\n - Accept: `.png,.jpg,.jpeg,.bmp,.tiff,.webp,.svg` via accept attribute\n - On file selection: store `File` in parent state, show filename + file size, render thumbnail via `URL.createObjectURL()`\n - Detect SVG uploads (check file type or extension) and surface this to parent for mode switching\n4. Create `app/src/components/PresetSelector.tsx`:\n - On mount: call `getPresets()` from `app/src/api/engine.ts`\n - Render preset cards — each shows name and description from the preset config\n - Clicking a card selects it (visual highlight) and calls `onPresetSelect(presetName, presetConfig)` callback\n - Default selection: 'sign' preset\n5. Create `app/src/App.css` (or global styles) with minimal layout: flexbox two-column layout for View 1, card styles for presets, drop zone styling with dashed border + hover state.\n6.

Add `CORSMiddleware` to `engine/main.py` — import from `fastapi.middleware.cors`, allow all origins for dev (restrict in production later). Place it before the router include.\n2. Scaffold `app/` using `npm create vite@latest app -- --template react-ts`. Run `cd app && npm install`.\n3. Configure `app/vite.config.ts` with a dev proxy: requests to `/engine/*` forward to `http://localhost:8000`.\n4. Create `app/src/types/engine.ts` with TypeScript interfaces:\n - `PresetConfig` — matches the JSON structure in `engine/presets/*.json` (name, description, preprocessing, vectorization, postprocessing sections)\n - `TraceResponse` — `{ output: string, format: string, metadata: TraceMetadata }`\n - `TraceMetadata` — `{ format: string, path_count: number, node_count_total: number, open_paths: number, island_count: number, warnings: string[], processing_ms: number }`\n - `PresetsResponse` — `{ presets: Record }`\n5. Create `app/src/api/engine.ts` with typed functions:\n - `getPresets(): Promise` — calls `GET /engine/presets`\n - `traceImage(file: File, preset: string, params: Record, signal?: AbortSignal): Promise` — builds `FormData` with file, mode, output_format='svg', preset, and params (JSON.stringify), calls `POST /engine/trace`\n - `simplifyVector(file: File, epsilon: number, signal?: AbortSignal): Promise` — calls `POST /engine/simplify`\n6. Remove Vite boilerplate: delete `app/src/App.css`, the counter component content from `App.tsx`, and the Vite/React logos.\n7. Add Vitest as dev dependency: `cd app && npm install -D vitest @testing-library/react @testing-library/jest-dom jsdom`. Configure in `vite.config.ts` with `test: { environment: 'jsdom', globals: true }`.\n8. Write `app/src/api/__tests__/engine.test.ts` — unit tests for the API client using `vi.fn()` to mock fetch. Test that `traceImage()` builds correct FormData, `getPresets()` calls the right URL, and AbortSignal is passed through.\n - Estimate: 45m\n - Files: engine/main.py, app/package.json, app/vite.config.ts, app/tsconfig.json, app/src/types/engine.ts, app/src/api/engine.ts, app/src/api/__tests__/engine.test.ts, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20\n- [ ] **T02: Build app shell with view routing, file upload zone, and preset selector** — Build the first user-facing components: the app shell with view-state routing (Import → Canvas → Export), a drag-and-drop file upload zone, and a preset selector that fetches presets from the engine and populates parameter defaults.\n\n## Steps\n\n1. Create `app/src/views/ImportConvert.tsx` — the main View 1 container. Layout: left panel (upload + controls) and right panel (preview area, placeholder for now). Use CSS modules or a single `app/src/views/ImportConvert.module.css`.\n2. Update `app/src/App.tsx` with view-state routing using React useState:\n - `type ViewState = 'import' | 'canvas' | 'export'`\n - Render `ImportConvert` when state is 'import', placeholder `
View 2: Design Canvas
` for 'canvas', placeholder for 'export'\n - Pass a callback `onUseThis(svgOutput: string, metadata: TraceMetadata)` that transitions to 'canvas'\n3. Create `app/src/components/FileUpload.tsx`:\n - Drag-and-drop zone with `onDragOver`/`onDrop` handlers + hidden file `` fallback\n - Accept: `.png,.jpg,.jpeg,.bmp,.tiff,.webp,.svg` via accept attribute\n - On file selection: store `File` in parent state, show filename + file size, render thumbnail via `URL.createObjectURL()`\n - Detect SVG uploads (check file type or extension) and surface this to parent for mode switching\n4. Create `app/src/components/PresetSelector.tsx`:\n - On mount: call `getPresets()` from `app/src/api/engine.ts`\n - Render preset cards — each shows name and description from the preset config\n - Clicking a card selects it (visual highlight) and calls `onPresetSelect(presetName, presetConfig)` callback\n - Default selection: 'sign' preset\n5. Create `app/src/App.css` (or global styles) with minimal layout: flexbox two-column layout for View 1, card styles for presets, drop zone styling with dashed border + hover state.\n6. Wire components together in `ImportConvert.tsx`: FileUpload at top, PresetSelector below it, both in the left panel. Store selected file and preset in local state.\n - Estimate: 1h\n - Files: app/src/App.tsx, app/src/App.css, app/src/views/ImportConvert.tsx, app/src/views/ImportConvert.module.css, app/src/components/FileUpload.tsx, app/src/components/PresetSelector.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [ ] **T03: Implement parameter sliders and debounced live SVG preview with AbortController** — Build the core interaction loop: parameter sliders derived from preset defaults, debounced re-trace on any change, AbortController-based request cancellation, and inline SVG rendering. This is the highest-risk piece of the slice.\n\n## Steps\n\n1. Create `app/src/hooks/useDebouncedTrace.ts` — a custom hook that encapsulates the debounce + abort logic:\n - Accepts: `file: File | null`, `preset: string`, `params: Record`, `debounceMs: number` (default 300)\n - Maintains an `AbortController` ref. On each trigger: clear previous timeout, abort previous request, set new timeout\n - After debounce: call `traceImage(file, preset, params, signal)` from the API client\n - Returns: `{ svgOutput: string | null, metadata: TraceMetadata | null, isLoading: boolean, error: string | null }`\n - On unmount: abort any in-flight request and clear timeout\n - For SVG file uploads: call `simplifyVector()` instead of `traceImage()`\n2. Create `app/src/components/ParameterSliders.tsx`:\n - Accepts current preset config and an `onChange(params)` callback\n - Renders labeled range inputs for key parameters:\n - **Detail Level** (epsilon): range 0.5–10, step 0.5, from postprocessing.epsilon\n - **Noise Filter** (filter_speckle/turdsize): range 0–50, step 1, from vectorization params\n - **Smooth Curves** (alphamax): range 0–1.334, step 0.1, from vectorization.potrace.alphamax\n - **Corner Threshold** (corner_threshold): range 0–180, step 1, from vectorization.vtracer.corner_threshold (only shown for vtracer mode)\n - Show/hide sliders based on vectorization mode (potrace vs vtracer) from preset\n - Each slider change calls `onChange` with the full current params object\n - Show current numeric value next to each slider\n3. Create `app/src/components/SvgPreview.tsx`:\n - Accepts `svgOutput: string | null`, `isLoading: boolean`, `error: string | null`\n - When loading: show a spinner/overlay\n - When error: show error message with retry suggestion\n - When SVG available: render via `dangerouslySetInnerHTML` inside a container div\n - Strip `width` and `height` attributes from the SVG string (keep viewBox) for responsive scaling\n - Apply CSS: `width: 100%; height: auto; max-height: 70vh; object-fit: contain` on the container\n4. Wire everything in `ImportConvert.tsx`:\n - Track `currentParams` state, initialized from selected preset defaults\n - When preset changes: reset params to new preset defaults, trigger re-trace\n - When slider changes: update params, trigger re-trace via the debounced hook\n - When file changes: trigger immediate trace (no debounce for initial upload)\n - Pass svgOutput/isLoading/error to SvgPreview\n5. Write `app/src/hooks/__tests__/useDebouncedTrace.test.ts` — test the hook with mocked fetch:\n - Verify debounce behavior (multiple rapid calls → only last fires)\n - Verify abort: mock AbortController, confirm signal is passed and previous request aborted\n - Verify SVG mode detection routes to simplifyVector\n - Estimate: 1h30m\n - Files: app/src/hooks/useDebouncedTrace.ts, app/src/components/ParameterSliders.tsx, app/src/components/SvgPreview.tsx, app/src/views/ImportConvert.tsx, app/src/hooks/__tests__/useDebouncedTrace.test.ts\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [ ] **T04: Add output info bar, Use This flow, error states, and verify full integration** — Complete the slice by adding the output info bar with color-coded stats, the 'Use This' button that advances to View 2, error/empty states, and a full-stack integration verification.\n\n## Steps\n\n1. Create `app/src/components/OutputInfoBar.tsx`:\n - Accepts `metadata: TraceMetadata | null`\n - When metadata is null: render nothing or a muted placeholder\n - Render stats: Path Count, Total Nodes, Open Paths, Processing Time\n - Color coding: green for normal values, yellow when node_count_total > 5000, red when open_paths > 0\n - Show warnings from metadata.warnings array if any\n2. Add 'Use This' button to `ImportConvert.tsx`:\n - Disabled when no SVG output is available\n - On click: call `onUseThis(svgOutput, metadata)` prop, which App.tsx uses to transition view state to 'canvas'\n - Pass the SVG string forward (stored in App.tsx state for S02 to consume)\n3. Add empty/error states throughout:\n - No file selected: show upload prompt in preview area\n - API error: show error message in preview area with status code\n - Loading: show spinner overlay on preview\n4. Write `app/src/components/__tests__/OutputInfoBar.test.tsx` — test color coding logic:\n - Normal metadata → green indicators\n - High node count → yellow indicator\n - Open paths > 0 → red indicator\n - Null metadata → no crash, placeholder shown\n5. Final verification: ensure `npx tsc --noEmit` passes with zero errors, `npx vitest run` passes all tests, and all components are wired together end-to-end.\n - Estimate: 45m\n - Files: app/src/components/OutputInfoBar.tsx, app/src/components/__tests__/OutputInfoBar.test.tsx, app/src/views/ImportConvert.tsx, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n"}],"isError":false,"timestamp":1774501326146}} +{"type":"message","id":"f796e69e","parentId":"58443bd0","timestamp":"2026-03-26T05:02:11.579Z","message":{"role":"assistant","content":[{"type":"text","text":"The plan rendered correctly.

All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/S01-PLAN.md`\n- Task plan source: `.gsd/milestones/M002/slices/S01/tasks/T01-PLAN.md`\n- Prior task summaries in this slice:\n- (no prior tasks)\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T01-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T01-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T01 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M002/slices/S01/S01-PLAN.md`\n**Goal:** Build the Import & Convert view (View 1) as a React SPA that integrates with the Engine API — users upload a raster image, select a vectorization preset, tune parameters via sliders, see a live SVG preview updated via debounced re-trace, and click \"Use This\" to advance to the Design Canvas.\n**Demo:** After this: Upload a PNG, see live preview with preset selection and slider controls, click 'Use This' to advance to canvas\n\n## UNIT: Execute Task T01 (\"Add engine CORS, scaffold Vite+React+TS app, build typed API client\") — Slice S01 (\"Import & Convert UI (View 1)\"), Milestone M002\n\n## Resume State\n- No continue file present.

Create `app/src/views/ImportConvert.tsx` — the main View 1 container. Layout: left panel (upload + controls) and right panel (preview area, placeholder for now). Use CSS modules or a single `app/src/views/ImportConvert.module.css`.\n2. Update `app/src/App.tsx` with view-state routing using React useState:\n - `type ViewState = 'import' | 'canvas' | 'export'`\n - Render `ImportConvert` when state is 'import', placeholder `
View 2: Design Canvas
` for 'canvas', placeholder for 'export'\n - Pass a callback `onUseThis(svgOutput: string, metadata: TraceMetadata)` that transitions to 'canvas'\n3. Create `app/src/components/FileUpload.tsx`:\n - Drag-and-drop zone with `onDragOver`/`onDrop` handlers + hidden file `` fallback\n - Accept: `.png,.jpg,.jpeg,.bmp,.tiff,.webp,.svg` via accept attribute\n - On file selection: store `File` in parent state, show filename + file size, render thumbnail via `URL.createObjectURL()`\n - Detect SVG uploads (check file type or extension) and surface this to parent for mode switching\n4. Create `app/src/components/PresetSelector.tsx`:\n - On mount: call `getPresets()` from `app/src/api/engine.ts`\n - Render preset cards — each shows name and description from the preset config\n - Clicking a card selects it (visual highlight) and calls `onPresetSelect(presetName, presetConfig)` callback\n - Default selection: 'sign' preset\n5. Create `app/src/App.css` (or global styles) with minimal layout: flexbox two-column layout for View 1, card styles for presets, drop zone styling with dashed border + hover state.\n6. Wire components together in `ImportConvert.tsx`: FileUpload at top, PresetSelector below it, both in the left panel. Store selected file and preset in local state.\n - Estimate: 1h\n - Files: app/src/App.tsx, app/src/App.css, app/src/views/ImportConvert.tsx, app/src/views/ImportConvert.module.css, app/src/components/FileUpload.tsx, app/src/components/PresetSelector.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [ ] **T03: Implement parameter sliders and debounced live SVG preview with AbortController** — Build the core interaction loop: parameter sliders derived from preset defaults, debounced re-trace on any change, AbortController-based request cancellation, and inline SVG rendering. This is the highest-risk piece of the slice.\n\n## Steps\n\n1. Create `app/src/hooks/useDebouncedTrace.ts` — a custom hook that encapsulates the debounce + abort logic:\n - Accepts: `file: File | null`, `preset: string`, `params: Record`, `debounceMs: number` (default 300)\n - Maintains an `AbortController` ref. On each trigger: clear previous timeout, abort previous request, set new timeout\n - After debounce: call `traceImage(file, preset, params, signal)` from the API client\n - Returns: `{ svgOutput: string | null, metadata: TraceMetadata | null, isLoading: boolean, error: string | null }`\n - On unmount: abort any in-flight request and clear timeout\n - For SVG file uploads: call `simplifyVector()` instead of `traceImage()`\n2. Create `app/src/components/ParameterSliders.tsx`:\n - Accepts current preset config and an `onChange(params)` callback\n - Renders labeled range inputs for key parameters:\n - **Detail Level** (epsilon): range 0.5–10, step 0.5, from postprocessing.epsilon\n - **Noise Filter** (filter_speckle/turdsize): range 0–50, step 1, from vectorization params\n - **Smooth Curves** (alphamax): range 0–1.334, step 0.1, from vectorization.potrace.alphamax\n - **Corner Threshold** (corner_threshold): range 0–180, step 1, from vectorization.vtracer.corner_threshold (only shown for vtracer mode)\n - Show/hide sliders based on vectorization mode (potrace vs vtracer) from preset\n - Each slider change calls `onChange` with the full current params object\n - Show current numeric value next to each slider\n3. Create `app/src/components/SvgPreview.tsx`:\n - Accepts `svgOutput: string | null`, `isLoading: boolean`, `error: string | null`\n - When loading: show a spinner/overlay\n - When error: show error message with retry suggestion\n - When SVG available: render via `dangerouslySetInnerHTML` inside a container div\n - Strip `width` and `height` attributes from the SVG string (keep viewBox) for responsive scaling\n - Apply CSS: `width: 100%; height: auto; max-height: 70vh; object-fit: contain` on the container\n4. Wire everything in `ImportConvert.tsx`:\n - Track `currentParams` state, initialized from selected preset defaults\n - When preset changes: reset params to new preset defaults, trigger re-trace\n - When slider changes: update params, trigger re-trace via the debounced hook\n - When file changes: trigger immediate trace (no debounce for initial upload)\n - Pass svgOutput/isLoading/error to SvgPreview\n5. Write `app/src/hooks/__tests__/useDebouncedTrace.test.ts` — test the hook with mocked fetch:\n - Verify debounce behavior (multiple rapid calls → only last fires)\n - Verify abort: mock AbortController, confirm signal is passed and previous request aborted\n - Verify SVG mode detection routes to simplifyVector\n - Estimate: 1h30m\n - Files: app/src/hooks/useDebouncedTrace.ts, app/src/components/ParameterSliders.tsx, app/src/components/SvgPreview.tsx, app/src/views/ImportConvert.tsx, app/src/hooks/__tests__/useDebouncedTrace.test.ts\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [ ] **T04: Add output info bar, Use This flow, error states, and verify full integration** — Complete the slice by adding the output info bar with color-coded stats, the 'Use This' button that advances to View 2, error/empty states, and a full-stack integration verification.\n\n## Steps\n\n1. Create `app/src/components/OutputInfoBar.tsx`:\n - Accepts `metadata: TraceMetadata | null`\n - When metadata is null: render nothing or a muted placeholder\n - Render stats: Path Count, Total Nodes, Open Paths, Processing Time\n - Color coding: green for normal values, yellow when node_count_total > 5000, red when open_paths > 0\n - Show warnings from metadata.warnings array if any\n2. Add 'Use This' button to `ImportConvert.tsx`:\n - Disabled when no SVG output is available\n - On click: call `onUseThis(svgOutput, metadata)` prop, which App.tsx uses to transition view state to 'canvas'\n - Pass the SVG string forward (stored in App.tsx state for S02 to consume)\n3. Add empty/error states throughout:\n - No file selected: show upload prompt in preview area\n - API error: show error message in preview area with status code\n - Loading: show spinner overlay on preview\n4. Write `app/src/components/__tests__/OutputInfoBar.test.tsx` — test color coding logic:\n - Normal metadata → green indicators\n - High node count → yellow indicator\n - Open paths > 0 → red indicator\n - Null metadata → no crash, placeholder shown\n5. Final verification: ensure `npx tsc --noEmit` passes with zero errors, `npx vitest run` passes all tests, and all components are wired together end-to-end.\n - Estimate: 45m\n - Files: app/src/components/OutputInfoBar.tsx, app/src/components/__tests__/OutputInfoBar.test.tsx, app/src/views/ImportConvert.tsx, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n"}],"isError":false,"timestamp":1774501342809}} +{"type":"message","id":"15761d40","parentId":"ad7f5ea9","timestamp":"2026-03-26T05:02:22.810Z","message":{"role":"toolResult","toolCallId":"toolu_014YgKygp9cNAmnUbrothYvJ","toolName":"read","content":[{"type":"text","text":"---\nestimated_steps: 17\nestimated_files: 8\nskills_used: []\n---\n\n# T01: Add engine CORS, scaffold Vite+React+TS app, build typed API client\n\nThis task unblocks all frontend work by: (1) adding CORSMiddleware to engine/main.py so browser requests succeed, (2) scaffolding the app/ directory as a Vite + React + TypeScript project with dev proxy to the engine, and (3) building a typed API client with TypeScript interfaces matching the engine's request/response shapes.\n\n## Steps\n\n1.

Create `app/src/types/engine.ts` with TypeScript interfaces:\n - `PresetConfig` — matches the JSON structure in `engine/presets/*.json` (name, description, preprocessing, vectorization, postprocessing sections)\n - `TraceResponse` — `{ output: string, format: string, metadata: TraceMetadata }`\n - `TraceMetadata` — `{ format: string, path_count: number, node_count_total: number, open_paths: number, island_count: number, warnings: string[], processing_ms: number }`\n - `PresetsResponse` — `{ presets: Record }`\n5. Create `app/src/api/engine.ts` with typed functions:\n - `getPresets(): Promise` — calls `GET /engine/presets`\n - `traceImage(file: File, preset: string, params: Record, signal?: AbortSignal): Promise` — builds `FormData` with file, mode, output_format='svg', preset, and params (JSON.stringify), calls `POST /engine/trace`\n - `simplifyVector(file: File, epsilon: number, signal?: AbortSignal): Promise` — calls `POST /engine/simplify`\n6. Remove Vite boilerplate: delete `app/src/App.css`, the counter component content from `App.tsx`, and the Vite/React logos.\n7. Add Vitest as dev dependency: `cd app && npm install -D vitest @testing-library/react @testing-library/jest-dom jsdom`. Configure in `vite.config.ts` with `test: { environment: 'jsdom', globals: true }`.\n8. Write `app/src/api/__tests__/engine.test.ts` — unit tests for the API client using `vi.fn()` to mock fetch. Test that `traceImage()` builds correct FormData, `getPresets()` calls the right URL, and AbortSignal is passed through.\n\n## Inputs\n\n- `engine/main.py`\n- `engine/api/routes.py`\n- `engine/presets/sign.json`\n\n## Expected Output\n\n- `engine/main.py`\n- `app/package.json`\n- `app/vite.config.ts`\n- `app/tsconfig.json`\n- `app/src/types/engine.ts`\n- `app/src/api/engine.ts`\n- `app/src/api/__tests__/engine.test.ts`\n- `app/src/App.tsx`\n- `app/src/main.tsx`\n\n## Verification\n\ncd app && npx vitest run --reporter=verbose 2>&1 | tail -20\n"}],"isError":false,"timestamp":1774501342809}} +{"type":"message","id":"bf052eb8","parentId":"15761d40","timestamp":"2026-03-26T05:02:22.812Z","message":{"role":"toolResult","toolCallId":"toolu_01Wohy1twANbEwe6M9e838dR","toolName":"read","content":[{"type":"text","text":"\"\"\"Kerf Engine — raster-to-vector conversion API.\"\"\"\n\nfrom fastapi import FastAPI\n\nfrom api.routes import router\n\napp = FastAPI(\n title=\"Kerf Engine\",\n description=\"Raster-to-vector conversion pipeline with Potrace and VTracer modes\",\n version=\"0.1.0\",\n)\n\napp.include_router(router)\n\n\n@app.get(\"/health\")\nasync def health():\n return {\"status\": \"ok\"}\n"}],"isError":false,"timestamp":1774501342810}} +{"type":"message","id":"0eaf7e04","parentId":"bf052eb8","timestamp":"2026-03-26T05:02:26.643Z","message":{"role":"assistant","content":[{"type":"text","text":"Good, I have a clear picture of the codebase.

Added `CORSMiddleware` to `engine/main.py` allowing all origins for dev, placed before the router include.\n2. Scaffolded `app/` via `npm create vite@latest app -- --template react-ts` and ran `npm install`.\n3. Configured `app/vite.config.ts` with a dev proxy (`/engine` → `http://localhost:8000`) and Vitest config (`jsdom` environment, globals enabled, test-setup file).\n4. Created `app/src/types/engine.ts` with full TypeScript interfaces matching the engine's preset JSON structure (`PresetConfig`, `PreprocessingConfig`, `PotraceConfig`, `VtracerConfig`, `VectorizationConfig`, `PostprocessingConfig`) and API responses (`TraceResponse`, `TraceMetadata`, `PresetsResponse`).\n5. Created `app/src/api/engine.ts` with three typed functions: `getPresets()`, `traceImage()`, and `simplifyVector()`. All throw descriptive errors on non-ok responses and accept an optional `AbortSignal`.\n6. Removed Vite boilerplate (`App.css`, counter component) and replaced `App.tsx` with a minimal shell.\n7. Installed `vitest`, `@testing-library/react`, `@testing-library/jest-dom`, `jsdom`, and `@types/node` as dev dependencies. Added `vitest/globals` to tsconfig types.\n8. Wrote 9 unit tests in `app/src/api/__tests__/engine.test.ts` covering all three API functions: correct URL/method, FormData construction, AbortSignal passthrough, and error handling.\n\n## Verification\n\n- `cd app && npx vitest run --reporter=verbose` — all 9 tests pass (3 per API function).\n- `cd app && npx tsc --noEmit` — zero TypeScript errors.\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `cd app && npx vitest run --reporter=verbose` | 0 | ✅ pass | 895ms |\n| 2 | `cd app && npx tsc --noEmit` | 0 | ✅ pass | ~2s |\n\n## Diagnostics\n\n- Run `cd app && npx vitest run` to re-verify API client tests.\n- Run `cd app && npx tsc --noEmit` to check type safety.\n- Dev server: `cd app && npm run dev` (proxies `/engine/*` to `:8000`).\n\n## Deviations\n\n- Added `@types/node` as a dev dependency (not in plan) — needed for Node.js type resolution in vitest environment.\n- Added `vitest/globals` to `tsconfig.app.json` types array — required for `describe`/`it`/`expect` to be recognized without imports when `globals: true`.\n- Added a `test-setup.ts` file importing `@testing-library/jest-dom/vitest` — needed for DOM matchers in future component tests.\n\n## Known Issues\n\nNone.\n\n## Files Created/Modified\n\n- `engine/main.py` — Added CORSMiddleware with allow-all origins for dev\n- `app/vite.config.ts` — Configured dev proxy and Vitest environment\n- `app/tsconfig.app.json` — Added vitest/globals to types array\n- `app/src/types/engine.ts` — TypeScript interfaces for all engine API shapes\n- `app/src/api/engine.ts` — Typed API client (getPresets, traceImage, simplifyVector)\n- `app/src/api/__tests__/engine.test.ts` — 9 unit tests for API client\n- `app/src/App.tsx` — Minimal shell replacing Vite boilerplate\n- `app/src/test-setup.ts` — Vitest setup importing jest-dom matchers\n- `app/package.json` — Dependencies (Vite scaffold + vitest + testing-library)\n","path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T01-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1492,"cacheRead":70021,"cacheWrite":601,"totalTokens":72115,"cost":{"input":0.000005,"output":0.0373,"cacheRead":0.0350105,"cacheWrite":0.00375625,"total":0.07607175000000001}},"stopReason":"toolUse","timestamp":1774501481019}} +{"type":"message","id":"9ca41060","parentId":"bb4f07e1","timestamp":"2026-03-26T05:05:11.096Z","message":{"role":"toolResult","toolCallId":"toolu_011mwbyc9nkprvDRYU3nCBR1","toolName":"write","content":[{"type":"text","text":"Successfully wrote 4432 bytes to /home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T01-SUMMARY.md"}],"isError":false,"timestamp":1774501511094}} +{"type":"message","id":"d8fbe66e","parentId":"9ca41060","timestamp":"2026-03-26T05:05:22.612Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_01TAanTR5wa9vrmhnq6hAPar","name":"gsd_task_complete","arguments":{"blockerDiscovered":false,"deviations":"Added @types/node as dev dependency (not in plan) for Node.js type resolution.

All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/S01-PLAN.md`\n- Task plan source: `.gsd/milestones/M002/slices/S01/tasks/T02-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M002/slices/S01/tasks/T01-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T02-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T02-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T02 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M002/slices/S01/S01-PLAN.md`\n**Goal:** Build the Import & Convert view (View 1) as a React SPA that integrates with the Engine API — users upload a raster image, select a vectorization preset, tune parameters via sliders, see a live SVG preview updated via debounced re-trace, and click \"Use This\" to advance to the Design Canvas.\n**Demo:** After this: Upload a PNG, see live preview with preset selection and slider controls, click 'Use This' to advance to canvas\n\n## UNIT: Execute Task T02 (\"Build app shell with view routing, file upload zone, and preset selector\") — Slice S01 (\"Import & Convert UI (View 1)\"), Milestone M002\n\n## Resume State\n- No continue file present.

Add `CORSMiddleware` to `engine/main.py` — import from `fastapi.middleware.cors`, allow all origins for dev (restrict in production later). Place it before the router include.\n2. Scaffold `app/` using `npm create vite@latest app -- --template react-ts`. Run `cd app && npm install`.\n3. Configure `app/vite.config.ts` with a dev proxy: requests to `/engine/*` forward to `http://localhost:8000`.\n4. Create `app/src/types/engine.ts` with TypeScript interfaces:\n - `PresetConfig` — matches the JSON structure in `engine/presets/*.json` (name, description, preprocessing, vectorization, postprocessing sections)\n - `TraceResponse` — `{ output: string, format: string, metadata: TraceMetadata }`\n - `TraceMetadata` — `{ format: string, path_count: number, node_count_total: number, open_paths: number, island_count: number, warnings: string[], processing_ms: number }`\n - `PresetsResponse` — `{ presets: Record }`\n5. Create `app/src/api/engine.ts` with typed functions:\n - `getPresets(): Promise` — calls `GET /engine/presets`\n - `traceImage(file: File, preset: string, params: Record, signal?: AbortSignal): Promise` — builds `FormData` with file, mode, output_format='svg', preset, and params (JSON.stringify), calls `POST /engine/trace`\n - `simplifyVector(file: File, epsilon: number, signal?: AbortSignal): Promise` — calls `POST /engine/simplify`\n6. Remove Vite boilerplate: delete `app/src/App.css`, the counter component content from `App.tsx`, and the Vite/React logos.\n7. Add Vitest as dev dependency: `cd app && npm install -D vitest @testing-library/react @testing-library/jest-dom jsdom`. Configure in `vite.config.ts` with `test: { environment: 'jsdom', globals: true }`.\n8. Write `app/src/api/__tests__/engine.test.ts` — unit tests for the API client using `vi.fn()` to mock fetch. Test that `traceImage()` builds correct FormData, `getPresets()` calls the right URL, and AbortSignal is passed through.\n - Estimate: 45m\n - Files: engine/main.py, app/package.json, app/vite.config.ts, app/tsconfig.json, app/src/types/engine.ts, app/src/api/engine.ts, app/src/api/__tests__/engine.test.ts, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20\n- [ ] **T02: Build app shell with view routing, file upload zone, and preset selector** — Build the first user-facing components: the app shell with view-state routing (Import → Canvas → Export), a drag-and-drop file upload zone, and a preset selector that fetches presets from the engine and populates parameter defaults.\n\n## Steps\n\n1. Create `app/src/views/ImportConvert.tsx` — the main View 1 container. Layout: left panel (upload + controls) and right panel (preview area, placeholder for now). Use CSS modules or a single `app/src/views/ImportConvert.module.css`.\n2. Update `app/src/App.tsx` with view-state routing using React useState:\n - `type ViewState = 'import' | 'canvas' | 'export'`\n - Render `ImportConvert` when state is 'import', placeholder `
View 2: Design Canvas
` for 'canvas', placeholder for 'export'\n - Pass a callback `onUseThis(svgOutput: string, metadata: TraceMetadata)` that transitions to 'canvas'\n3. Create `app/src/components/FileUpload.tsx`:\n - Drag-and-drop zone with `onDragOver`/`onDrop` handlers + hidden file `` fallback\n - Accept: `.png,.jpg,.jpeg,.bmp,.tiff,.webp,.svg` via accept attribute\n - On file selection: store `File` in parent state, show filename + file size, render thumbnail via `URL.createObjectURL()`\n - Detect SVG uploads (check file type or extension) and surface this to parent for mode switching\n4. Create `app/src/components/PresetSelector.tsx`:\n - On mount: call `getPresets()` from `app/src/api/engine.ts`\n - Render preset cards — each shows name and description from the preset config\n - Clicking a card selects it (visual highlight) and calls `onPresetSelect(presetName, presetConfig)` callback\n - Default selection: 'sign' preset\n5. Create `app/src/App.css` (or global styles) with minimal layout: flexbox two-column layout for View 1, card styles for presets, drop zone styling with dashed border + hover state.\n6. Wire components together in `ImportConvert.tsx`: FileUpload at top, PresetSelector below it, both in the left panel. Store selected file and preset in local state.\n - Estimate: 1h\n - Files: app/src/App.tsx, app/src/App.css, app/src/views/ImportConvert.tsx, app/src/views/ImportConvert.module.css, app/src/components/FileUpload.tsx, app/src/components/PresetSelector.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [ ] **T03: Implement parameter sliders and debounced live SVG preview with AbortController** — Build the core interaction loop: parameter sliders derived from preset defaults, debounced re-trace on any change, AbortController-based request cancellation, and inline SVG rendering. This is the highest-risk piece of the slice.\n\n## Steps\n\n1. Create `app/src/hooks/useDebouncedTrace.ts` — a custom hook that encapsulates the debounce + abort logic:\n - Accepts: `file: File | null`, `preset: string`, `params: Record`, `debounceMs: number` (default 300)\n - Maintains an `AbortController` ref. On each trigger: clear previous timeout, abort previous request, set new timeout\n - After debounce: call `traceImage(file, preset, params, signal)` from the API client\n - Returns: `{ svgOutput: string | null, metadata: TraceMetadata | null, isLoading: boolean, error: string | null }`\n - On unmount: abort any in-flight request and clear timeout\n - For SVG file uploads: call `simplifyVector()` instead of `traceImage()`\n2. Create `app/src/components/ParameterSliders.tsx`:\n - Accepts current preset config and an `onChange(params)` callback\n - Renders labeled range inputs for key parameters:\n - **Detail Level** (epsilon): range 0.5–10, step 0.5, from postprocessing.epsilon\n - **Noise Filter** (filter_speckle/turdsize): range 0–50, step 1, from vectorization params\n - **Smooth Curves** (alphamax): range 0–1.334, step 0.1, from vectorization.potrace.alphamax\n - **Corner Threshold** (corner_threshold): range 0–180, step 1, from vectorization.vtracer.corner_threshold (only shown for vtracer mode)\n - Show/hide sliders based on vectorization mode (potrace vs vtracer) from preset\n - Each slider change calls `onChange` with the full current params object\n - Show current numeric value next to each slider\n3. Create `app/src/components/SvgPreview.tsx`:\n - Accepts `svgOutput: string | null`, `isLoading: boolean`, `error: string | null`\n - When loading: show a spinner/overlay\n - When error: show error message with retry suggestion\n - When SVG available: render via `dangerouslySetInnerHTML` inside a container div\n - Strip `width` and `height` attributes from the SVG string (keep viewBox) for responsive scaling\n - Apply CSS: `width: 100%; height: auto; max-height: 70vh; object-fit: contain` on the container\n4. Wire everything in `ImportConvert.tsx`:\n - Track `currentParams` state, initialized from selected preset defaults\n - When preset changes: reset params to new preset defaults, trigger re-trace\n - When slider changes: update params, trigger re-trace via the debounced hook\n - When file changes: trigger immediate trace (no debounce for initial upload)\n - Pass svgOutput/isLoading/error to SvgPreview\n5. Write `app/src/hooks/__tests__/useDebouncedTrace.test.ts` — test the hook with mocked fetch:\n - Verify debounce behavior (multiple rapid calls → only last fires)\n - Verify abort: mock AbortController, confirm signal is passed and previous request aborted\n - Verify SVG mode detection routes to simplifyVector\n - Estimate: 1h30m\n - Files: app/src/hooks/useDebouncedTrace.ts, app/src/components/ParameterSliders.tsx, app/src/components/SvgPreview.tsx, app/src/views/ImportConvert.tsx, app/src/hooks/__tests__/useDebouncedTrace.test.ts\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [ ] **T04: Add output info bar, Use This flow, error states, and verify full integration** — Complete the slice by adding the output info bar with color-coded stats, the 'Use This' button that advances to View 2, error/empty states, and a full-stack integration verification.\n\n## Steps\n\n1. Create `app/src/components/OutputInfoBar.tsx`:\n - Accepts `metadata: TraceMetadata | null`\n - When metadata is null: render nothing or a muted placeholder\n - Render stats: Path Count, Total Nodes, Open Paths, Processing Time\n - Color coding: green for normal values, yellow when node_count_total > 5000, red when open_paths > 0\n - Show warnings from metadata.warnings array if any\n2. Add 'Use This' button to `ImportConvert.tsx`:\n - Disabled when no SVG output is available\n - On click: call `onUseThis(svgOutput, metadata)` prop, which App.tsx uses to transition view state to 'canvas'\n - Pass the SVG string forward (stored in App.tsx state for S02 to consume)\n3. Add empty/error states throughout:\n - No file selected: show upload prompt in preview area\n - API error: show error message in preview area with status code\n - Loading: show spinner overlay on preview\n4. Write `app/src/components/__tests__/OutputInfoBar.test.tsx` — test color coding logic:\n - Normal metadata → green indicators\n - High node count → yellow indicator\n - Open paths > 0 → red indicator\n - Null metadata → no crash, placeholder shown\n5. Final verification: ensure `npx tsc --noEmit` passes with zero errors, `npx vitest run` passes all tests, and all components are wired together end-to-end.\n - Estimate: 45m\n - Files: app/src/components/OutputInfoBar.tsx, app/src/components/__tests__/OutputInfoBar.test.tsx, app/src/views/ImportConvert.tsx, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n"}],"isError":false,"timestamp":1774501535284}} +{"type":"message","id":"9dc54f1f","parentId":"4eafb13f","timestamp":"2026-03-26T05:05:39.824Z","message":{"role":"assistant","content":[{"type":"text","text":"Now let me read the existing source files to understand the current state."},{"type":"toolCall","id":"toolu_015fTo4VaVkEj31gT6cefWZt","name":"read","arguments":{"path":"app/src/App.tsx"}},{"type":"toolCall","id":"toolu_01SFMCxp1Hn3UGErcMGg7dEy","name":"read","arguments":{"path":"app/src/types/engine.ts"}},{"type":"toolCall","id":"toolu_01CWR2uPsr7NeZWsbf5q7Kob","name":"read","arguments":{"path":"app/src/api/engine.ts"}},{"type":"toolCall","id":"toolu_01GGXcPXskkrWA3RnjKNhyg1","name":"read","arguments":{"path":"app/src/main.tsx"}},{"type":"toolCall","id":"toolu_01V5sECioUTF51YhWvjHCsJL","name":"bash","arguments":{"command":"ls app/src/ && echo \"---\" && ls app/src/api/ 2>/dev/null && echo \"---\" && cat app/package.json | head -30"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":270,"cacheRead":53204,"cacheWrite":5562,"totalTokens":59037,"cost":{"input":0.000005,"output":0.00675,"cacheRead":0.026601999999999997,"cacheWrite":0.0347625,"total":0.0681195}},"stopReason":"toolUse","timestamp":1774501535285}} +{"type":"message","id":"dfa851ef","parentId":"9dc54f1f","timestamp":"2026-03-26T05:05:39.831Z","message":{"role":"toolResult","toolCallId":"toolu_015fTo4VaVkEj31gT6cefWZt","toolName":"read","content":[{"type":"text","text":"function App() {\n return (\n

Built FileUpload component with drag-and-drop zone using onDragOver/onDrop handlers plus a hidden file input fallback, thumbnail rendering via URL.createObjectURL, file size display, and SVG file detection (by MIME type or extension) for mode switching. Built PresetSelector that fetches presets from the engine API on mount with AbortController cleanup, renders preset cards in a 2-column grid with selected state highlighting, and auto-selects 'sign' as the default. Updated App.tsx with a ViewState type union ('import' | 'canvas' | 'export') and conditional rendering — ImportConvert for 'import', placeholder divs for 'canvas' and 'export'. Created App.css with global styles for the upload zone (dashed border, hover/drag-over accent highlight), preset cards (border highlight, grid layout), and placeholder views. Wired state in ImportConvert: selectedFile, isSvgMode, selectedPreset, and presetConfig are tracked in local state for T03 to consume.\n\n## Verification\n\nRan `npx tsc --noEmit` — zero TypeScript errors across all new and existing files. Ran `npx vitest run --reporter=verbose` — all 9 existing API client tests pass. No new tests added in this task (component tests deferred to T04 per slice plan).\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `cd app && npx vitest run --reporter=verbose` | 0 | ✅ pass | 832ms |\n| 2 | `cd app && npx tsc --noEmit` | 0 | ✅ pass | 2000ms |\n\n## Diagnostics\n\nRun `cd app && npm run dev` to see the ImportConvert view in the browser at localhost:5173. The preset selector requires the engine API at localhost:8000 (proxied via Vite dev server). Without the engine running, the preset selector will show an error state.\n\n## Deviations\n\nNone.

All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/S01-PLAN.md`\n- Task plan source: `.gsd/milestones/M002/slices/S01/tasks/T03-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M002/slices/S01/tasks/T01-SUMMARY.md`\n- `.gsd/milestones/M002/slices/S01/tasks/T02-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T03-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T03-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T03 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M002/slices/S01/S01-PLAN.md`\n**Goal:** Build the Import & Convert view (View 1) as a React SPA that integrates with the Engine API — users upload a raster image, select a vectorization preset, tune parameters via sliders, see a live SVG preview updated via debounced re-trace, and click \"Use This\" to advance to the Design Canvas.\n**Demo:** After this: Upload a PNG, see live preview with preset selection and slider controls, click 'Use This' to advance to canvas\n\n## UNIT: Execute Task T03 (\"Implement parameter sliders and debounced live SVG preview with AbortController\") — Slice S01 (\"Import & Convert UI (View 1)\"), Milestone M002\n\n## Resume State\n- No continue file present.

This is the highest-risk piece of the slice.\n\n## Steps\n\n1. Create `app/src/hooks/useDebouncedTrace.ts` — a custom hook that encapsulates the debounce + abort logic:\n - Accepts: `file: File | null`, `preset: string`, `params: Record`, `debounceMs: number` (default 300)\n - Maintains an `AbortController` ref. On each trigger: clear previous timeout, abort previous request, set new timeout\n - After debounce: call `traceImage(file, preset, params, signal)` from the API client\n - Returns: `{ svgOutput: string | null, metadata: TraceMetadata | null, isLoading: boolean, error: string | null }`\n - On unmount: abort any in-flight request and clear timeout\n - For SVG file uploads: call `simplifyVector()` instead of `traceImage()`\n2. Create `app/src/components/ParameterSliders.tsx`:\n - Accepts current preset config and an `onChange(params)` callback\n - Renders labeled range inputs for key parameters:\n - **Detail Level** (epsilon): range 0.5–10, step 0.5, from postprocessing.epsilon\n - **Noise Filter** (filter_speckle/turdsize): range 0–50, step 1, from vectorization params\n - **Smooth Curves** (alphamax): range 0–1.334, step 0.1, from vectorization.potrace.alphamax\n - **Corner Threshold** (corner_threshold): range 0–180, step 1, from vectorization.vtracer.corner_threshold (only shown for vtracer mode)\n - Show/hide sliders based on vectorization mode (potrace vs vtracer) from preset\n - Each slider change calls `onChange` with the full current params object\n - Show current numeric value next to each slider\n3. Create `app/src/components/SvgPreview.tsx`:\n - Accepts `svgOutput: string | null`, `isLoading: boolean`, `error: string | null`\n - When loading: show a spinner/overlay\n - When error: show error message with retry suggestion\n - When SVG available: render via `dangerouslySetInnerHTML` inside a container div\n - Strip `width` and `height` attributes from the SVG string (keep viewBox) for responsive scaling\n - Apply CSS: `width: 100%; height: auto; max-height: 70vh; object-fit: contain` on the container\n4. Wire everything in `ImportConvert.tsx`:\n - Track `currentParams` state, initialized from selected preset defaults\n - When preset changes: reset params to new preset defaults, trigger re-trace\n - When slider changes: update params, trigger re-trace via the debounced hook\n - When file changes: trigger immediate trace (no debounce for initial upload)\n - Pass svgOutput/isLoading/error to SvgPreview\n5. Write `app/src/hooks/__tests__/useDebouncedTrace.test.ts` — test the hook with mocked fetch:\n - Verify debounce behavior (multiple rapid calls → only last fires)\n - Verify abort: mock AbortController, confirm signal is passed and previous request aborted\n - Verify SVG mode detection routes to simplifyVector\n\n## Inputs\n\n- `app/src/api/engine.ts`\n- `app/src/types/engine.ts`\n- `app/src/views/ImportConvert.tsx`\n- `app/src/components/PresetSelector.tsx`\n\n## Expected Output\n\n- `app/src/hooks/useDebouncedTrace.ts`\n- `app/src/components/ParameterSliders.tsx`\n- `app/src/components/SvgPreview.tsx`\n- `app/src/views/ImportConvert.tsx`\n- `app/src/hooks/__tests__/useDebouncedTrace.test.ts`\n\n## Verification\n\ncd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n","display":false,"id":"53917d4d","parentId":"570598b5","timestamp":"2026-03-26T05:07:37.271Z"} +{"type":"message","id":"aaca1364","parentId":"53917d4d","timestamp":"2026-03-26T05:07:42.356Z","message":{"role":"assistant","content":[{"type":"text","text":"\n\nI'll start by reading the task plan, prior summaries, and the current codebase state to understand what's been built and what I need to implement."},{"type":"toolCall","id":"toolu_019P8W1ubvGayDpABMF7sweq","name":"read","arguments":{"path":".gsd/milestones/M002/slices/S01/tasks/T03-PLAN.md"}},{"type":"toolCall","id":"toolu_01C3K7wPpZxkXo1ioRuQyWoy","name":"read","arguments":{"path":".gsd/milestones/M002/slices/S01/tasks/T01-SUMMARY.md"}},{"type":"toolCall","id":"toolu_01P2PVtmnxvupfmqGawABHwM","name":"read","arguments":{"path":".gsd/milestones/M002/slices/S01/tasks/T02-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":2,"output":229,"cacheRead":49688,"cacheWrite":3973,"totalTokens":53892,"cost":{"input":0.00001,"output":0.005725,"cacheRead":0.024843999999999998,"cacheWrite":0.024831250000000003,"total":0.05541025}},"stopReason":"toolUse","timestamp":1774501657270}} +{"type":"message","id":"9bb1b84d","parentId":"aaca1364","timestamp":"2026-03-26T05:07:42.359Z","message":{"role":"toolResult","toolCallId":"toolu_019P8W1ubvGayDpABMF7sweq","toolName":"read","content":[{"type":"text","text":"---\nestimated_steps: 36\nestimated_files: 5\nskills_used: []\n---\n\n# T03: Implement parameter sliders and debounced live SVG preview with AbortController\n\nBuild the core interaction loop: parameter sliders derived from preset defaults, debounced re-trace on any change, AbortController-based request cancellation, and inline SVG rendering.

helping because the problem is deeper: when using fake timers, `waitFor` uses `setTimeout` under the hood to poll, and those are also fake. The issue is that `setTimeout` inside the callback from `triggerTrace` creates a timer under fake timer control, but the `await` inside that setTimeout's callback (the fetch) creates a microtask that never resolves because the event loop is frozen.\n\nThe real fix is to not use `setTimeout` inside `useEffect` for the async work. Instead, I should restructure the hook so the test interaction is cleaner. However, a simpler approach: use real timers for the async parts and only test the observable behavior with `waitFor` + real timers, using smaller debounce

The error is `null` when checked, meaning the error state was never set. Let me check the hook more carefully.\n\nThe issue: when `traceImage` throws, the hook catches the error. But in the catch, it checks `err instanceof Error && err.name === 'AbortError'` first — that should be fine for a non-abort error. Then it checks `!controller.signal.aborted` — the controller should not be aborted. Let me add some debugging by checking the actual `mockFetchFail` flow.\n\nActually, I think the problem is that `mockFetchFail` returns `ok: false`, and `traceImage` does `await res.text()` to get the detail. But `mockFetchFail` returns a real `text()` promise, so that should work. Let me inspect closer — the hook calls `traceImage(file, preset, params, controller.signal)` where `params` is `{ epsilon: 2 }`. Let me check what the fetch mock is actually doing:\n\nThe mock's `text()` returns `Promise.resolve(detail)`. The `traceImage` function: `const detail = await res.text().catch(() => res.statusText)`. Then `throw new Error(...)`. This should be caught by the `catch (err)` block. \n\nHmm, wait — looking at the hook code again, the `triggerTrace` function is called inside the `useEffect`, but `triggerTrace` is created with `useCallback` that depends on `[file, preset, params]`. The `useEffect` depends on `[file, preset, params, debounceMs, triggerTrace]`. When the hook is first rendered, `triggerTrace` is created, the effect runs, calling `triggerTrace(debounceMs)`. Inside that, `setTimeout` fires after `DEBOUNCE_MS` (10ms), which calls `traceImage` which throws. The catch block should set the error.\n\nLet me test with a direct console.log approach to understand:"},{"type":"toolCall","id":"toolu_012YfUupk3kmiNUucKWjjSdn","name":"bash","arguments":{"command":"cd /home/aux/development/xpltdco/kerf-engine/app && npx vitest run -t \"sets error\" --reporter=verbose 2>&1 | tail -30","timeout":30}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":599,"cacheRead":91537,"cacheWrite":369,"totalTokens":92506,"cost":{"input":0.000005,"output":0.014975,"cacheRead":0.0457685,"cacheWrite":0.00230625,"total":0.06305474999999999}},"stopReason":"toolUse","timestamp":1774501968388}} +{"type":"message","id":"60058243","parentId":"bc446e20","timestamp":"2026-03-26T05:13:05.456Z","message":{"role":"toolResult","toolCallId":"toolu_012YfUupk3kmiNUucKWjjSdn","toolName":"bash","content":[{"type":"text","text":" \u001b[36m\u001b[31m\n \u001b[36m

Let me hypothesize: the thrown error might be caught by the setTimeout's async function, but since `setTimeout` callback errors are unhandled rejections in async functions, and `React.act` might be swallowing them. Actually — `setTimeout` with an `async` callback: if the async callback inside the timeout throws, it becomes an unhandled promise rejection, not a caught error. \n\nWait no — the `setTimeout` callback is an `async () => { ... }` — when the `try/catch` inside that async function catches the error, it calls `setError(...)`. But the issue is that React may not be re-rendering because the state update happens inside an untracked `setTimeout` callback (not wrapped in `act`).\n\nThe real problem: the state update happens asynchronously from a `setTimeout` callback. React doesn't know about it. In testing with `@testing-library/react`, `waitFor` polls the DOM periodically. The state update from `setError` inside the setTimeout callback should trigger a re-render...\n\nActually, I bet the issue is that the catch block checks `!controller.signal.aborted`. But maybe by the time the error is thrown, the cleanup function from the effect has run (because the component re-renders after `setIsLoading(true)`), which aborts the controller. Let me trace this more carefully.\n\nWhen the hook renders:\n1. Effect runs → calls `triggerTrace(10)`\n2. `triggerTrace` sets `isLoading: true`, then sets a 10ms `setTimeout`\n3. `setIsLoading(true)` causes a re-render\n4. Re-render → effect cleanup runs → **aborts the controller** and clears the timeout!\n\nThat's the bug. The cleanup function runs on every effect re-run, including when the effect dependencies change due to the state update from `setIsLoading`. But `triggerTrace` is in the deps via `useCallback` — and `setIsLoading(true)` doesn't change the deps, so the effect shouldn't re-run.\n\nWait, let me re-read the hook. The effect depends on `[file, preset, params, debounceMs, triggerTrace]`. `triggerTrace` is a `useCallback` depending on `[file, preset, params]`. Setting `isLoading` doesn't change these deps, so the effect should NOT re-run. But `waitFor` polls every 50ms and after 2000ms still sees `error: null`.\n\nLet me add a debug log to the hook temporarily:"},{"type":"toolCall","id":"toolu_01E3geN3U1Pdp31LiVgVCjJh","name":"bash","arguments":{"command":"cd /home/aux/development/xpltdco/kerf-engine/app && cat > /tmp/debug-test.ts << 'EOF'\nimport { describe, it, expect, vi, beforeEach, afterEach } from 'vitest';\nimport { renderHook, waitFor } from '@testing-library/react';\nimport { useDebouncedTrace } from '../src/hooks/useDebouncedTrace';\n\nfunction mockFetchFail(status: number, detail: string) {\n return vi.fn().mockResolvedValue({\n ok: false,\n status,\n statusText: detail,\n text: () => Promise.resolve(detail),\n });\n}\n\nconst originalFetch = globalThis.fetch;\n\nbeforeEach(() => {\n globalThis.fetch = vi.fn().mockRejectedValue(new Error('fetch not mocked'));\n});\n\nafterEach(() => {\n globalThis.fetch = originalFetch;\n});\n\ndescribe('debug', () => {\n it('error test', async () => {\n const fetchMock = mockFetchFail(500, 'Internal Server Error');\n globalThis.fetch = fetchMock;\n const file = new File(['pixels'], 'test.png', { type: 'image/png' });\n\n const { result } = renderHook(() =>\n useDebouncedTrace(file, 'sign', { epsilon: 2 }, 10),\n );\n\n // Wait a good while for the debounce + fetch to complete\n await new Promise(r => setTimeout(r, 200));\n\n console.log('fetch called:', fetchMock.mock.calls.length);\n console.log('error:', result.current.error);\n console.log('isLoading:', result.current.isLoading);\n console.log('svgOutput:', result.current.svgOutput);\n\n expect(result.current.error).toBeTruthy();\n });\n});\nEOF\necho \"done\""}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1106,"cacheRead":91906,"cacheWrite":1297,"totalTokens":94310,"cost":{"input":0.000005,"output":0.02765,"cacheRead":0.045953,"cacheWrite":0.00810625,"total":0.08171425}},"stopReason":"toolUse","timestamp":1774501985455}} +{"type":"message","id":"91041e53","parentId":"6ec3f6e9","timestamp":"2026-03-26T05:13:27.783Z","message":{"role":"toolResult","toolCallId":"toolu_01E3geN3U1Pdp31LiVgVCjJh","toolName":"bash","content":[{"type":"text","text":"done\n"}],"isError":false,"timestamp":1774502007781}} +{"type":"message","id":"a292b8ba","parentId":"91041e53","timestamp":"2026-03-26T05:13:41.892Z","message":{"role":"assistant","content":[{"type":"text","text":"Let me think about this differently. The problem is likely that the `triggerTrace` `useCallback` changes identity on re-render because `params` is a new object reference each time.

In `ImportConvert.tsx` I have `stableParams` using `JSON.stringify`, but in the hook tests I'm passing the object directly.\n\nWait, actually in the test: `renderHook(() => useDebouncedTrace(file, 'sign', { epsilon: 2 }, DEBOUNCE_MS))`. On every render cycle, `{ epsilon: 2 }` is a new object reference. The `useCallback` depends on `[file, preset, params]`, so `triggerTrace` gets a new identity each render. The effect depends on `triggerTrace`, so it re-runs each render. Each effect cleanup aborts the previous controller and clears the timeout.\n\nThis creates an infinite loop: effect runs → sets `isLoading` → re-render → `triggerTrace` new identity (new `params` ref) → effect cleanup (abort!) → effect runs again → sets `isLoading` → ...\n\nThe fix: the hook should stabilize `params` internally, similar to how `ImportConvert` does with `stableParams`.

Add `CORSMiddleware` to `engine/main.py` — import from `fastapi.middleware.cors`, allow all origins for dev (restrict in production later). Place it before the router include.\n2. Scaffold `app/` using `npm create vite@latest app -- --template react-ts`. Run `cd app && npm install`.\n3. Configure `app/vite.config.ts` with a dev proxy: requests to `/engine/*` forward to `http://localhost:8000`.\n4. Create `app/src/types/engine.ts` with TypeScript interfaces:\n - `PresetConfig` — matches the JSON structure in `engine/presets/*.json` (name, description, preprocessing, vectorization, postprocessing sections)\n - `TraceResponse` — `{ output: string, format: string, metadata: TraceMetadata }`\n - `TraceMetadata` — `{ format: string, path_count: number, node_count_total: number, open_paths: number, island_count: number, warnings: string[], processing_ms: number }`\n - `PresetsResponse` — `{ presets: Record }`\n5. Create `app/src/api/engine.ts` with typed functions:\n - `getPresets(): Promise` — calls `GET /engine/presets`\n - `traceImage(file: File, preset: string, params: Record, signal?: AbortSignal): Promise` — builds `FormData` with file, mode, output_format='svg', preset, and params (JSON.stringify), calls `POST /engine/trace`\n - `simplifyVector(file: File, epsilon: number, signal?: AbortSignal): Promise` — calls `POST /engine/simplify`\n6. Remove Vite boilerplate: delete `app/src/App.css`, the counter component content from `App.tsx`, and the Vite/React logos.\n7. Add Vitest as dev dependency: `cd app && npm install -D vitest @testing-library/react @testing-library/jest-dom jsdom`. Configure in `vite.config.ts` with `test: { environment: 'jsdom', globals: true }`.\n8. Write `app/src/api/__tests__/engine.test.ts` — unit tests for the API client using `vi.fn()` to mock fetch. Test that `traceImage()` builds correct FormData, `getPresets()` calls the right URL, and AbortSignal is passed through.\n - Estimate: 45m\n - Files: engine/main.py, app/package.json, app/vite.config.ts, app/tsconfig.json, app/src/types/engine.ts, app/src/api/engine.ts, app/src/api/__tests__/engine.test.ts, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20\n- [x] **T02: Built app shell with ViewState routing, drag-and-drop FileUpload with thumbnail preview, PresetSelector fetching from engine API, and two-column ImportConvert layout** — Build the first user-facing components: the app shell with view-state routing (Import → Canvas → Export), a drag-and-drop file upload zone, and a preset selector that fetches presets from the engine and populates parameter defaults.\n\n## Steps\n\n1. Create `app/src/views/ImportConvert.tsx` — the main View 1 container. Layout: left panel (upload + controls) and right panel (preview area, placeholder for now). Use CSS modules or a single `app/src/views/ImportConvert.module.css`.\n2. Update `app/src/App.tsx` with view-state routing using React useState:\n - `type ViewState = 'import' | 'canvas' | 'export'`\n - Render `ImportConvert` when state is 'import', placeholder `
View 2: Design Canvas
` for 'canvas', placeholder for 'export'\n - Pass a callback `onUseThis(svgOutput: string, metadata: TraceMetadata)` that transitions to 'canvas'\n3. Create `app/src/components/FileUpload.tsx`:\n - Drag-and-drop zone with `onDragOver`/`onDrop` handlers + hidden file `` fallback\n - Accept: `.png,.jpg,.jpeg,.bmp,.tiff,.webp,.svg` via accept attribute\n - On file selection: store `File` in parent state, show filename + file size, render thumbnail via `URL.createObjectURL()`\n - Detect SVG uploads (check file type or extension) and surface this to parent for mode switching\n4. Create `app/src/components/PresetSelector.tsx`:\n - On mount: call `getPresets()` from `app/src/api/engine.ts`\n - Render preset cards — each shows name and description from the preset config\n - Clicking a card selects it (visual highlight) and calls `onPresetSelect(presetName, presetConfig)` callback\n - Default selection: 'sign' preset\n5. Create `app/src/App.css` (or global styles) with minimal layout: flexbox two-column layout for View 1, card styles for presets, drop zone styling with dashed border + hover state.\n6. Wire components together in `ImportConvert.tsx`: FileUpload at top, PresetSelector below it, both in the left panel. Store selected file and preset in local state.\n - Estimate: 1h\n - Files: app/src/App.tsx, app/src/App.css, app/src/views/ImportConvert.tsx, app/src/views/ImportConvert.module.css, app/src/components/FileUpload.tsx, app/src/components/PresetSelector.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [ ] **T03: Implement parameter sliders and debounced live SVG preview with AbortController** — Build the core interaction loop: parameter sliders derived from preset defaults, debounced re-trace on any change, AbortController-based request cancellation, and inline SVG rendering. This is the highest-risk piece of the slice.\n\n## Steps\n\n1. Create `app/src/hooks/useDebouncedTrace.ts` — a custom hook that encapsulates the debounce + abort logic:\n - Accepts: `file: File | null`, `preset: string`, `params: Record`, `debounceMs: number` (default 300)\n - Maintains an `AbortController` ref. On each trigger: clear previous timeout, abort previous request, set new timeout\n - After debounce: call `traceImage(file, preset, params, signal)` from the API client\n - Returns: `{ svgOutput: string | null, metadata: TraceMetadata | null, isLoading: boolean, error: string | null }`\n - On unmount: abort any in-flight request and clear timeout\n - For SVG file uploads: call `simplifyVector()` instead of `traceImage()`\n2. Create `app/src/components/ParameterSliders.tsx`:\n - Accepts current preset config and an `onChange(params)` callback\n - Renders labeled range inputs for key parameters:\n - **Detail Level** (epsilon): range 0.5–10, step 0.5, from postprocessing.epsilon\n - **Noise Filter** (filter_speckle/turdsize): range 0–50, step 1, from vectorization params\n - **Smooth Curves** (alphamax): range 0–1.334, step 0.1, from vectorization.potrace.alphamax\n - **Corner Threshold** (corner_threshold): range 0–180, step 1, from vectorization.vtracer.corner_threshold (only shown for vtracer mode)\n - Show/hide sliders based on vectorization mode (potrace vs vtracer) from preset\n - Each slider change calls `onChange` with the full current params object\n - Show current numeric value next to each slider\n3. Create `app/src/components/SvgPreview.tsx`:\n - Accepts `svgOutput: string | null`, `isLoading: boolean`, `error: string | null`\n - When loading: show a spinner/overlay\n - When error: show error message with retry suggestion\n - When SVG available: render via `dangerouslySetInnerHTML` inside a container div\n - Strip `width` and `height` attributes from the SVG string (keep viewBox) for responsive scaling\n - Apply CSS: `width: 100%; height: auto; max-height: 70vh; object-fit: contain` on the container\n4. Wire everything in `ImportConvert.tsx`:\n - Track `currentParams` state, initialized from selected preset defaults\n - When preset changes: reset params to new preset defaults, trigger re-trace\n - When slider changes: update params, trigger re-trace via the debounced hook\n - When file changes: trigger immediate trace (no debounce for initial upload)\n - Pass svgOutput/isLoading/error to SvgPreview\n5. Write `app/src/hooks/__tests__/useDebouncedTrace.test.ts` — test the hook with mocked fetch:\n - Verify debounce behavior (multiple rapid calls → only last fires)\n - Verify abort: mock AbortController, confirm signal is passed and previous request aborted\n - Verify SVG mode detection routes to simplifyVector\n - Estimate: 1h30m\n - Files: app/src/hooks/useDebouncedTrace.ts, app/src/components/ParameterSliders.tsx, app/src/components/SvgPreview.tsx, app/src/views/ImportConvert.tsx, app/src/hooks/__tests__/useDebouncedTrace.test.ts\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [ ] **T04: Add output info bar, Use This flow, error states, and verify full integration** — Complete the slice by adding the output info bar with color-coded stats, the 'Use This' button that advances to View 2, error/empty states, and a full-stack integration verification.\n\n## Steps\n\n1. Create `app/src/components/OutputInfoBar.tsx`:\n - Accepts `metadata: TraceMetadata | null`\n - When metadata is null: render nothing or a muted placeholder\n - Render stats: Path Count, Total Nodes, Open Paths, Processing Time\n - Color coding: green for normal values, yellow when node_count_total > 5000, red when open_paths > 0\n - Show warnings from metadata.warnings array if any\n2. Add 'Use This' button to `ImportConvert.tsx`:\n - Disabled when no SVG output is available\n - On click: call `onUseThis(svgOutput, metadata)` prop, which App.tsx uses to transition view state to 'canvas'\n - Pass the SVG string forward (stored in App.tsx state for S02 to consume)\n3. Add empty/error states throughout:\n - No file selected: show upload prompt in preview area\n - API error: show error message in preview area with status code\n - Loading: show spinner overlay on preview\n4. Write `app/src/components/__tests__/OutputInfoBar.test.tsx` — test color coding logic:\n - Normal metadata → green indicators\n - High node count → yellow indicator\n - Open paths > 0 → red indicator\n - Null metadata → no crash, placeholder shown\n5. Final verification: ensure `npx tsc --noEmit` passes with zero errors, `npx vitest run` passes all tests, and all components are wired together end-to-end.\n - Estimate: 45m\n - Files: app/src/components/OutputInfoBar.tsx, app/src/components/__tests__/OutputInfoBar.test.tsx, app/src/views/ImportConvert.tsx, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n"}],"isError":false,"timestamp":1774502065517}} +{"type":"message","id":"adabca6a","parentId":"93055e0b","timestamp":"2026-03-26T05:14:30.483Z","message":{"role":"assistant","content":[{"type":"text","text":"Good.

SVG file uploads route to `simplifyVector()` instead of `traceImage()`. Parameters are stabilized internally via `JSON.stringify` to prevent infinite re-render loops from new object references in React effects.\n\nBuilt `ParameterSliders` component that dynamically renders labeled range sliders based on the active vectorization mode — potrace shows Detail Level (epsilon), Noise Filter (turdsize), and Smooth Curves (alphamax); vtracer shows Detail Level, Noise Filter (filter_speckle), and Corner Threshold. Each slider shows its current numeric value and calls `onChange` with the full params object on input.\n\nBuilt `SvgPreview` component that renders three states: loading (animated spinner), error (message with retry hint), and ready (responsive SVG via `dangerouslySetInnerHTML` with width/height attributes stripped for viewBox-based scaling). When SVG is displayed, a metadata bar shows path count, node count, processing time, and any warnings.\n\nWired everything in `ImportConvert.tsx`: `currentParams` state initialized from preset defaults, preset changes reset params and trigger re-trace, slider changes update params which the debounced hook picks up, SvgPreview receives the hook's output. Added a \"Use This →\" button that appears when SVG output is available, calling `onUseThis` to advance to the canvas view. Fixed `App.tsx` to use typed `TraceMetadata` instead of `unknown` for the callback parameter.\n\nAdded CSS for parameter sliders (grid layout with label/range/value columns, accent-colored values with tabular-nums), SVG preview states (spinner animation, error styling, responsive container), and the \"Use This\" button to App.css.\n\nWrote 7 tests for the hook covering: null file returns null output, debounce coalesces rapid changes to one fetch, AbortSignal passed to fetch and previous requests aborted, SVG files routed to /engine/simplify, raster files routed to /engine/trace, error state set on fetch failure, and cleanup on unmount cancels in-flight requests.\n\n## Verification\n\nRan `cd app && npx vitest run --reporter=verbose` — all 16 tests pass (9 API client + 7 useDebouncedTrace hook). Ran `cd app && npx tsc --noEmit` — zero TypeScript errors.\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `cd app && npx vitest run --reporter=verbose` | 0 | ✅ pass | 1820ms |\n| 2 | `cd app && npx tsc --noEmit` | 0 | ✅ pass | 2800ms |\n\n## Diagnostics\n\n- SvgPreview metadata bar shows path_count, node_count_total, processing_ms, and warnings from trace response — visible in the right panel when SVG output is available.\n- Hook exposes `isLoading` and `error` states for UI feedback on in-flight requests and failures.\n- Console will show unhandled rejection warnings if the engine API is unreachable during dev.\n\n## Deviations\n\n- Restructured the hook to use a single `useEffect` with `JSON.stringify(params)` in the dependency array instead of the planned `useCallback`-based `triggerTrace` approach. The callback approach caused infinite re-render loops when `params` object references changed between renders, which is the default behavior in React unless callers explicitly memoize. The JSON.stringify approach is simpler and self-contained.\n- Added \"Use This →\" button to ImportConvert in this task rather than T04, since it was natural to wire it alongside the SVG output state. T04 can still add the OutputInfoBar and enhance the button's disabled state.\n\n## Known Issues\n\nNone.\n\n## Files Created/Modified\n\n- `app/src/hooks/useDebouncedTrace.ts` — Custom hook with debounce + AbortController + SVG mode detection\n- `app/src/components/ParameterSliders.tsx` — Mode-aware parameter sliders derived from preset config\n- `app/src/components/SvgPreview.tsx` — Responsive SVG renderer with loading/error/ready states\n- `app/src/views/ImportConvert.tsx` — Wired complete live re-trace loop with all components\n- `app/src/hooks/__tests__/useDebouncedTrace.test.ts` — 7 tests covering debounce, abort, routing, errors, cleanup\n- `app/src/App.css` — Added slider, SVG preview, and button styles\n- `app/src/App.tsx` — Fixed onUseThis callback to use typed TraceMetadata\n","path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T03-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1755,"cacheRead":105469,"cacheWrite":604,"totalTokens":107829,"cost":{"input":0.000005,"output":0.043875000000000004,"cacheRead":0.0527345,"cacheWrite":0.003775,"total":0.10038949999999999}},"stopReason":"toolUse","timestamp":1774502082995}} +{"type":"message","id":"a8ec6a81","parentId":"e1587908","timestamp":"2026-03-26T05:15:22.178Z","message":{"role":"toolResult","toolCallId":"toolu_01HQCUGik51dRhZKgJj57jbZ","toolName":"write","content":[{"type":"text","text":"Successfully wrote 6076 bytes to /home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T03-SUMMARY.md"}],"isError":false,"timestamp":1774502122176}} +{"type":"message","id":"c9756adc","parentId":"a8ec6a81","timestamp":"2026-03-26T05:15:38.799Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_01VuipSDk8egzSZPLcVSzDVc","name":"gsd_task_complete","arguments":{"blockerDiscovered":false,"deviations":"Restructured hook to use single useEffect with JSON.stringify(params) in deps instead of useCallback-based triggerTrace approach — the callback approach caused infinite re-render loops.

All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/S01-PLAN.md`\n- Task plan source: `.gsd/milestones/M002/slices/S01/tasks/T04-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M002/slices/S01/tasks/T01-SUMMARY.md`\n- `.gsd/milestones/M002/slices/S01/tasks/T02-SUMMARY.md`\n- `.gsd/milestones/M002/slices/S01/tasks/T03-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T04-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T04-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T04 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M002/slices/S01/S01-PLAN.md`\n**Goal:** Build the Import & Convert view (View 1) as a React SPA that integrates with the Engine API — users upload a raster image, select a vectorization preset, tune parameters via sliders, see a live SVG preview updated via debounced re-trace, and click \"Use This\" to advance to the Design Canvas.\n**Demo:** After this: Upload a PNG, see live preview with preset selection and slider controls, click 'Use This' to advance to canvas\n\n## UNIT: Execute Task T04 (\"Add output info bar, Use This flow, error states, and verify full integration\") — Slice S01 (\"Import & Convert UI (View 1)\"), Milestone M002\n\n## Resume State\n- No continue file present.

Add `CORSMiddleware` to `engine/main.py` — import from `fastapi.middleware.cors`, allow all origins for dev (restrict in production later). Place it before the router include.\n2. Scaffold `app/` using `npm create vite@latest app -- --template react-ts`. Run `cd app && npm install`.\n3. Configure `app/vite.config.ts` with a dev proxy: requests to `/engine/*` forward to `http://localhost:8000`.\n4. Create `app/src/types/engine.ts` with TypeScript interfaces:\n - `PresetConfig` — matches the JSON structure in `engine/presets/*.json` (name, description, preprocessing, vectorization, postprocessing sections)\n - `TraceResponse` — `{ output: string, format: string, metadata: TraceMetadata }`\n - `TraceMetadata` — `{ format: string, path_count: number, node_count_total: number, open_paths: number, island_count: number, warnings: string[], processing_ms: number }`\n - `PresetsResponse` — `{ presets: Record }`\n5. Create `app/src/api/engine.ts` with typed functions:\n - `getPresets(): Promise` — calls `GET /engine/presets`\n - `traceImage(file: File, preset: string, params: Record, signal?: AbortSignal): Promise` — builds `FormData` with file, mode, output_format='svg', preset, and params (JSON.stringify), calls `POST /engine/trace`\n - `simplifyVector(file: File, epsilon: number, signal?: AbortSignal): Promise` — calls `POST /engine/simplify`\n6. Remove Vite boilerplate: delete `app/src/App.css`, the counter component content from `App.tsx`, and the Vite/React logos.\n7. Add Vitest as dev dependency: `cd app && npm install -D vitest @testing-library/react @testing-library/jest-dom jsdom`. Configure in `vite.config.ts` with `test: { environment: 'jsdom', globals: true }`.\n8. Write `app/src/api/__tests__/engine.test.ts` — unit tests for the API client using `vi.fn()` to mock fetch. Test that `traceImage()` builds correct FormData, `getPresets()` calls the right URL, and AbortSignal is passed through.\n - Estimate: 45m\n - Files: engine/main.py, app/package.json, app/vite.config.ts, app/tsconfig.json, app/src/types/engine.ts, app/src/api/engine.ts, app/src/api/__tests__/engine.test.ts, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20\n- [x] **T02: Built app shell with ViewState routing, drag-and-drop FileUpload with thumbnail preview, PresetSelector fetching from engine API, and two-column ImportConvert layout** — Build the first user-facing components: the app shell with view-state routing (Import → Canvas → Export), a drag-and-drop file upload zone, and a preset selector that fetches presets from the engine and populates parameter defaults.\n\n## Steps\n\n1. Create `app/src/views/ImportConvert.tsx` — the main View 1 container. Layout: left panel (upload + controls) and right panel (preview area, placeholder for now). Use CSS modules or a single `app/src/views/ImportConvert.module.css`.\n2. Update `app/src/App.tsx` with view-state routing using React useState:\n - `type ViewState = 'import' | 'canvas' | 'export'`\n - Render `ImportConvert` when state is 'import', placeholder `
View 2: Design Canvas
` for 'canvas', placeholder for 'export'\n - Pass a callback `onUseThis(svgOutput: string, metadata: TraceMetadata)` that transitions to 'canvas'\n3. Create `app/src/components/FileUpload.tsx`:\n - Drag-and-drop zone with `onDragOver`/`onDrop` handlers + hidden file `` fallback\n - Accept: `.png,.jpg,.jpeg,.bmp,.tiff,.webp,.svg` via accept attribute\n - On file selection: store `File` in parent state, show filename + file size, render thumbnail via `URL.createObjectURL()`\n - Detect SVG uploads (check file type or extension) and surface this to parent for mode switching\n4. Create `app/src/components/PresetSelector.tsx`:\n - On mount: call `getPresets()` from `app/src/api/engine.ts`\n - Render preset cards — each shows name and description from the preset config\n - Clicking a card selects it (visual highlight) and calls `onPresetSelect(presetName, presetConfig)` callback\n - Default selection: 'sign' preset\n5. Create `app/src/App.css` (or global styles) with minimal layout: flexbox two-column layout for View 1, card styles for presets, drop zone styling with dashed border + hover state.\n6. Wire components together in `ImportConvert.tsx`: FileUpload at top, PresetSelector below it, both in the left panel. Store selected file and preset in local state.\n - Estimate: 1h\n - Files: app/src/App.tsx, app/src/App.css, app/src/views/ImportConvert.tsx, app/src/views/ImportConvert.module.css, app/src/components/FileUpload.tsx, app/src/components/PresetSelector.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [x] **T03: Built useDebouncedTrace hook with AbortController cancellation, ParameterSliders with mode-aware controls, SvgPreview with responsive rendering, and wired the complete live re-trace loop in ImportConvert** — Build the core interaction loop: parameter sliders derived from preset defaults, debounced re-trace on any change, AbortController-based request cancellation, and inline SVG rendering. This is the highest-risk piece of the slice.\n\n## Steps\n\n1. Create `app/src/hooks/useDebouncedTrace.ts` — a custom hook that encapsulates the debounce + abort logic:\n - Accepts: `file: File | null`, `preset: string`, `params: Record`, `debounceMs: number` (default 300)\n - Maintains an `AbortController` ref. On each trigger: clear previous timeout, abort previous request, set new timeout\n - After debounce: call `traceImage(file, preset, params, signal)` from the API client\n - Returns: `{ svgOutput: string | null, metadata: TraceMetadata | null, isLoading: boolean, error: string | null }`\n - On unmount: abort any in-flight request and clear timeout\n - For SVG file uploads: call `simplifyVector()` instead of `traceImage()`\n2. Create `app/src/components/ParameterSliders.tsx`:\n - Accepts current preset config and an `onChange(params)` callback\n - Renders labeled range inputs for key parameters:\n - **Detail Level** (epsilon): range 0.5–10, step 0.5, from postprocessing.epsilon\n - **Noise Filter** (filter_speckle/turdsize): range 0–50, step 1, from vectorization params\n - **Smooth Curves** (alphamax): range 0–1.334, step 0.1, from vectorization.potrace.alphamax\n - **Corner Threshold** (corner_threshold): range 0–180, step 1, from vectorization.vtracer.corner_threshold (only shown for vtracer mode)\n - Show/hide sliders based on vectorization mode (potrace vs vtracer) from preset\n - Each slider change calls `onChange` with the full current params object\n - Show current numeric value next to each slider\n3. Create `app/src/components/SvgPreview.tsx`:\n - Accepts `svgOutput: string | null`, `isLoading: boolean`, `error: string | null`\n - When loading: show a spinner/overlay\n - When error: show error message with retry suggestion\n - When SVG available: render via `dangerouslySetInnerHTML` inside a container div\n - Strip `width` and `height` attributes from the SVG string (keep viewBox) for responsive scaling\n - Apply CSS: `width: 100%; height: auto; max-height: 70vh; object-fit: contain` on the container\n4. Wire everything in `ImportConvert.tsx`:\n - Track `currentParams` state, initialized from selected preset defaults\n - When preset changes: reset params to new preset defaults, trigger re-trace\n - When slider changes: update params, trigger re-trace via the debounced hook\n - When file changes: trigger immediate trace (no debounce for initial upload)\n - Pass svgOutput/isLoading/error to SvgPreview\n5. Write `app/src/hooks/__tests__/useDebouncedTrace.test.ts` — test the hook with mocked fetch:\n - Verify debounce behavior (multiple rapid calls → only last fires)\n - Verify abort: mock AbortController, confirm signal is passed and previous request aborted\n - Verify SVG mode detection routes to simplifyVector\n - Estimate: 1h30m\n - Files: app/src/hooks/useDebouncedTrace.ts, app/src/components/ParameterSliders.tsx, app/src/components/SvgPreview.tsx, app/src/views/ImportConvert.tsx, app/src/hooks/__tests__/useDebouncedTrace.test.ts\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [ ] **T04: Add output info bar, Use This flow, error states, and verify full integration** — Complete the slice by adding the output info bar with color-coded stats, the 'Use This' button that advances to View 2, error/empty states, and a full-stack integration verification.\n\n## Steps\n\n1. Create `app/src/components/OutputInfoBar.tsx`:\n - Accepts `metadata: TraceMetadata | null`\n - When metadata is null: render nothing or a muted placeholder\n - Render stats: Path Count, Total Nodes, Open Paths, Processing Time\n - Color coding: green for normal values, yellow when node_count_total > 5000, red when open_paths > 0\n - Show warnings from metadata.warnings array if any\n2. Add 'Use This' button to `ImportConvert.tsx`:\n - Disabled when no SVG output is available\n - On click: call `onUseThis(svgOutput, metadata)` prop, which App.tsx uses to transition view state to 'canvas'\n - Pass the SVG string forward (stored in App.tsx state for S02 to consume)\n3. Add empty/error states throughout:\n - No file selected: show upload prompt in preview area\n - API error: show error message in preview area with status code\n - Loading: show spinner overlay on preview\n4. Write `app/src/components/__tests__/OutputInfoBar.test.tsx` — test color coding logic:\n - Normal metadata → green indicators\n - High node count → yellow indicator\n - Open paths > 0 → red indicator\n - Null metadata → no crash, placeholder shown\n5. Final verification: ensure `npx tsc --noEmit` passes with zero errors, `npx vitest run` passes all tests, and all components are wired together end-to-end.\n - Estimate: 45m\n - Files: app/src/components/OutputInfoBar.tsx, app/src/components/__tests__/OutputInfoBar.test.tsx, app/src/views/ImportConvert.tsx, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n"}],"isError":false,"timestamp":1774502147763}} +{"type":"message","id":"9c074be2","parentId":"ca3456bc","timestamp":"2026-03-26T05:15:51.662Z","message":{"role":"assistant","content":[{"type":"text","text":"Now let me read the existing source files I need to modify and understand."},{"type":"toolCall","id":"toolu_01KGDZdDA5oEbwquDQHkR63e","name":"read","arguments":{"path":"app/src/types/engine.ts"}},{"type":"toolCall","id":"toolu_01Wp7cZvK5xy9ktqSHL634dh","name":"read","arguments":{"path":"app/src/views/ImportConvert.tsx"}},{"type":"toolCall","id":"toolu_01D833WGx9ikdZ5F18Zu8aWa","name":"read","arguments":{"path":"app/src/App.tsx"}},{"type":"toolCall","id":"toolu_01JbMGUvsMZecAwUNURap3ij","name":"read","arguments":{"path":"app/src/components/SvgPreview.tsx"}},{"type":"toolCall","id":"toolu_01CbZJCkc8c5U6EXDqDNrdGh","name":"read","arguments":{"path":"app/src/App.css"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":245,"cacheRead":53413,"cacheWrite":4164,"totalTokens":57823,"cost":{"input":0.000005,"output":0.006125,"cacheRead":0.026706499999999998,"cacheWrite":0.026025,"total":0.0588615}},"stopReason":"toolUse","timestamp":1774502147764}} +{"type":"message","id":"8186a128","parentId":"9c074be2","timestamp":"2026-03-26T05:15:51.665Z","message":{"role":"toolResult","toolCallId":"toolu_01KGDZdDA5oEbwquDQHkR63e","toolName":"read","content":[{"type":"text","text":"/** TypeScript interfaces matching the Kerf Engine API shapes. */\n\n// -- Preset configuration (mirrors engine/presets/*.json) --\n\nexport interface PreprocessingConfig {\n denoise_d?: number;\n denoise_sigma_color?: number;\n denoise_sigma_space?: number;\n clahe_clip_limit?: number;\n clahe_tile_grid_size?: [number, number];\n threshold_manual?: number | null;\n edge_detect?: boolean;\n morph_kernel_size?: number;\n morph_dilate_iterations?: number;\n morph_erode_iterations?: number;\n}\n\nexport interface PotraceConfig {\n turdsize?: number;\n alphamax?: number;\n opticurve?: boolean;\n opttolerance?: number;\n}\n\nexport interface VtracerConfig {\n colormode?: string;\n hierarchical?: string;\n filter_speckle?: number;\n corner_threshold?: number;\n length_threshold?: number;\n splice_threshold?: number;\n mode?: string;\n color_precision?: number;\n layer_difference?: number;\n path_precision?: number;\n max_iterations?: number;\n}\n\nexport interface VectorizationConfig {\n mode: 'potrace' | 'vtracer';\n potrace?: PotraceConfig;\n vtracer?: VtracerConfig;\n}\n\nexport interface PostprocessingConfig {\n epsilon?: number;\n close_tolerance?: number;\n auto_close?: boolean;\n}\n\nexport interface PresetConfig {\n name: string;\n description: string;\n preprocessing: PreprocessingConfig;\n vectorization: VectorizationConfig;\n postprocessing: PostprocessingConfig;\n}\n\n// -- API responses --\n\nexport interface TraceMetadata {\n format: string;\n path_count: number;\n node_count_total: number;\n open_paths: number;\n island_count: number;\n warnings: string[];\n processing_ms: number;\n}\n\nexport interface TraceResponse {\n output: string;\n format: string;\n metadata: TraceMetadata;\n}\n\nexport interface PresetsResponse {\n presets: Record;\n}\n"}],"isError":false,"timestamp":1774502151665}} +{"type":"message","id":"ba1a108d","parentId":"8186a128","timestamp":"2026-03-26T05:15:51.666Z","message":{"role":"toolResult","toolCallId":"toolu_01Wp7cZvK5xy9ktqSHL634dh","toolName":"read","content":[{"type":"text","text":"import { useCallback, useState } from 'react';\nimport type { PresetConfig, TraceMetadata } from '../types/engine';\nimport FileUpload from '../components/FileUpload';\nimport PresetSelector from '../components/PresetSelector';\nimport ParameterSliders from '../components/ParameterSliders';\nimport SvgPreview from '../components/SvgPreview';\nimport { useDebouncedTrace } from '../hooks/useDebouncedTrace';\nimport styles from './ImportConvert.module.css';\n\ninterface ImportConvertProps {\n onUseThis: (svgOutput: string, metadata: TraceMetadata) => void;\n}\n\n/**\n * Extract default slider parameters from a preset config.\n */\nfunction defaultParamsFromPreset(config: PresetConfig): Record {\n const mode = config.vectorization.mode;\n const params: Record = {\n epsilon: config.postprocessing.epsilon ??

When metadata is null, it shows a muted placeholder. Warnings from the metadata array render below the stats row.\n\nUpdated `ImportConvert.tsx` to import and render `OutputInfoBar` below the preview area and changed the \"Use This\" button from conditionally rendered to always visible with a `disabled` attribute (disabled when no SVG output or while loading). This avoids layout shift and makes the call-to-action discoverable.\n\nAdded CSS styles for the info bar including stat columns with tabular-nums for aligned numbers.\n\nWrote 7 tests for `OutputInfoBar` covering: null metadata placeholder, green indicators for normal values, yellow indicator for high node count, red indicator for open paths, simultaneous yellow+red, warnings display, and absent warnings container.\n\nEmpty/error/loading states were already implemented in `SvgPreview` during T03 — verified they remain correct. The full Import → Canvas flow works via `App.tsx`'s `handleUseThis` callback.\n\n## Verification\n\n- `npx tsc --noEmit`: zero errors, clean exit\n- `npx vitest run --reporter=verbose`: 23/23 tests pass across 3 test files\n - 9 API client tests\n - 7 OutputInfoBar tests (new)\n - 7 useDebouncedTrace hook tests\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `cd app && npx tsc --noEmit` | 0 | ✅ pass | 6.4s |\n| 2 | `cd app && npx vitest run --reporter=verbose` | 0 | ✅ pass | 2.5s |\n\n## Diagnostics\n\nNone — pure UI component, no runtime observability needed.\n\n## Deviations\n\n- \"Use This\" button changed from conditionally rendered (`{svgOutput && ...}`) to always rendered with `disabled={!svgOutput || isLoading}`. This is a better UX pattern (no layout shift, always visible CTA) and the plan's intent is preserved.\n- Empty/error/loading states in the preview area were already complete from T03's `SvgPreview` implementation — no additional work needed beyond verification.\n\n## Known Issues\n\nNone.\n\n## Files Created/Modified\n\n- `app/src/components/OutputInfoBar.tsx` — New component: color-coded stats bar for trace metadata\n- `app/src/components/__tests__/OutputInfoBar.test.tsx` — 7 tests for color coding logic and edge cases\n- `app/src/views/ImportConvert.tsx` — Added OutputInfoBar import/render, changed Use This to always-visible disabled pattern\n- `app/src/App.css` — Added OutputInfoBar styles (stats layout, color classes, warnings)\n","path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T04-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1149,"cacheRead":70878,"cacheWrite":597,"totalTokens":72625,"cost":{"input":0.000005,"output":0.028725,"cacheRead":0.035439,"cacheWrite":0.00373125,"total":0.06790025000000001}},"stopReason":"toolUse","timestamp":1774502229037}} +{"type":"message","id":"b72c8b76","parentId":"9d8d4b9a","timestamp":"2026-03-26T05:17:34.607Z","message":{"role":"toolResult","toolCallId":"toolu_0142r8dT1PSBgGD4Gc5ux95K","toolName":"write","content":[{"type":"text","text":"Successfully wrote 3790 bytes to /home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/tasks/T04-SUMMARY.md"}],"isError":false,"timestamp":1774502254606}} +{"type":"message","id":"399616d7","parentId":"b72c8b76","timestamp":"2026-03-26T05:17:44.405Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_01HjmNr2Y3tGRWuEmPsiHhyW","name":"gsd_task_complete","arguments":{"blockerDiscovered":false,"deviations":"Use This button changed from conditionally rendered to always-visible with disabled attribute — better UX (no layout shift).

View 1 integrates with the Engine API for vectorization with live preview. View 2 is a Konva.js-powered 2D design environment with artboard shapes, text objects, basic shapes, layers, alignment tools, and undo/redo.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Import & Convert UI (View 1) | medium — debounced preview updates, engine api integration from browser | — | ⬜ | Upload a PNG, see live preview with preset selection and slider controls, click 'Use This' to advance to canvas |\n| S02 | Design Canvas Core (View 2) | medium — konva.js setup, selection handles, undo/redo state management | S01 | ⬜ | Create artboards in each shape, add/move/resize shapes, multi-select with alignment, undo/redo through history |\n| S03 | Text System + Font Loading | medium — opentype.js integration, font loading from volume, path extraction accuracy | S02 | ⬜ | Add text objects, select fonts from picker, change size/spacing, convert text to paths — paths match original glyphs |\n\n---\n\n### Slice Plan\nSource: `.gsd/milestones/M002/slices/S01/S01-PLAN.md`\n\n# S01: Import & Convert UI (View 1)\n\n**Goal:** Build the Import & Convert view (View 1) as a React SPA that integrates with the Engine API — users upload a raster image, select a vectorization preset, tune parameters via sliders, see a live SVG preview updated via debounced re-trace, and click \"Use This\" to advance to the Design Canvas.\n**Demo:** After this: Upload a PNG, see live preview with preset selection and slider controls, click 'Use This' to advance to canvas\n\n## Tasks\n- [x] **T01: Added CORSMiddleware to engine, scaffolded Vite+React+TS app with dev proxy, and built typed API client with 9 passing tests** — This task unblocks all frontend work by: (1) adding CORSMiddleware to engine/main.py so browser requests succeed, (2) scaffolding the app/ directory as a Vite + React + TypeScript project with dev proxy to the engine, and (3) building a typed API client with TypeScript interfaces matching the engine's request/response shapes.\n\n## Steps\n\n1. Add `CORSMiddleware` to `engine/main.py` — import from `fastapi.middleware.cors`, allow all origins for dev (restrict in production later). Place it before the router include.\n2. Scaffold `app/` using `npm create vite@latest app -- --template react-ts`. Run `cd app && npm install`.\n3. Configure `app/vite.config.ts` with a dev proxy: requests to `/engine/*` forward to `http://localhost:8000`.\n4. Create `app/src/types/engine.ts` with TypeScript interfaces:\n - `PresetConfig` — matches the JSON structure in `engine/presets/*.json` (name, description, preprocessing, vectorization, postprocessing sections)\n - `TraceResponse` — `{ output: string, format: string, metadata: TraceMetadata }`\n - `TraceMetadata` — `{ format: string, path_count: number, node_count_total: number, open_paths: number, island_count: number, warnings: string[], processing_ms: number }`\n - `PresetsResponse` — `{ presets: Record }`\n5. Create `app/src/api/engine.ts` with typed functions:\n - `getPresets(): Promise` — calls `GET /engine/presets`\n - `traceImage(file: File, preset: string, params: Record, signal?: AbortSignal): Promise` — builds `FormData` with file, mode, output_format='svg', preset, and params (JSON.stringify), calls `POST /engine/trace`\n - `simplifyVector(file: File, epsilon: number, signal?: AbortSignal): Promise` — calls `POST /engine/simplify`\n6. Remove Vite boilerplate: delete `app/src/App.css`, the counter component content from `App.tsx`, and the Vite/React logos.\n7. Add Vitest as dev dependency: `cd app && npm install -D vitest @testing-library/react @testing-library/jest-dom jsdom`. Configure in `vite.config.ts` with `test: { environment: 'jsdom', globals: true }`.\n8. Write `app/src/api/__tests__/engine.test.ts` — unit tests for the API client using `vi.fn()` to mock fetch. Test that `traceImage()` builds correct FormData, `getPresets()` calls the right URL, and AbortSignal is passed through.\n - Estimate: 45m\n - Files: engine/main.py, app/package.json, app/vite.config.ts, app/tsconfig.json, app/src/types/engine.ts, app/src/api/engine.ts, app/src/api/__tests__/engine.test.ts, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20\n- [x] **T02: Built app shell with ViewState routing, drag-and-drop FileUpload with thumbnail preview, PresetSelector fetching from engine API, and two-column ImportConvert layout** — Build the first user-facing components: the app shell with view-state routing (Import → Canvas → Export), a drag-and-drop file upload zone, and a preset selector that fetches presets from the engine and populates parameter defaults.\n\n## Steps\n\n1. Create `app/src/views/ImportConvert.tsx` — the main View 1 container. Layout: left panel (upload + controls) and right panel (preview area, placeholder for now). Use CSS modules or a single `app/src/views/ImportConvert.module.css`.\n2. Update `app/src/App.tsx` with view-state routing using React useState:\n - `type ViewState = 'import' | 'canvas' | 'export'`\n - Render `ImportConvert` when state is 'import', placeholder `
View 2: Design Canvas
` for 'canvas', placeholder for 'export'\n - Pass a callback `onUseThis(svgOutput: string, metadata: TraceMetadata)` that transitions to 'canvas'\n3. Create `app/src/components/FileUpload.tsx`:\n - Drag-and-drop zone with `onDragOver`/`onDrop` handlers + hidden file `` fallback\n - Accept: `.png,.jpg,.jpeg,.bmp,.tiff,.webp,.svg` via accept attribute\n - On file selection: store `File` in parent state, show filename + file size, render thumbnail via `URL.createObjectURL()`\n - Detect SVG uploads (check file type or extension) and surface this to parent for mode switching\n4. Create `app/src/components/PresetSelector.tsx`:\n - On mount: call `getPresets()` from `app/src/api/engine.ts`\n - Render preset cards — each shows name and description from the preset config\n - Clicking a card selects it (visual highlight) and calls `onPresetSelect(presetName, presetConfig)` callback\n - Default selection: 'sign' preset\n5. Create `app/src/App.css` (or global styles) with minimal layout: flexbox two-column layout for View 1, card styles for presets, drop zone styling with dashed border + hover state.\n6. Wire components together in `ImportConvert.tsx`: FileUpload at top, PresetSelector below it, both in the left panel. Store selected file and preset in local state.\n - Estimate: 1h\n - Files: app/src/App.tsx, app/src/App.css, app/src/views/ImportConvert.tsx, app/src/views/ImportConvert.module.css, app/src/components/FileUpload.tsx, app/src/components/PresetSelector.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [x] **T03: Built useDebouncedTrace hook with AbortController cancellation, ParameterSliders with mode-aware controls, SvgPreview with responsive rendering, and wired the complete live re-trace loop in ImportConvert** — Build the core interaction loop: parameter sliders derived from preset defaults, debounced re-trace on any change, AbortController-based request cancellation, and inline SVG rendering. This is the highest-risk piece of the slice.\n\n## Steps\n\n1. Create `app/src/hooks/useDebouncedTrace.ts` — a custom hook that encapsulates the debounce + abort logic:\n - Accepts: `file: File | null`, `preset: string`, `params: Record`, `debounceMs: number` (default 300)\n - Maintains an `AbortController` ref. On each trigger: clear previous timeout, abort previous request, set new timeout\n - After debounce: call `traceImage(file, preset, params, signal)` from the API client\n - Returns: `{ svgOutput: string | null, metadata: TraceMetadata | null, isLoading: boolean, error: string | null }`\n - On unmount: abort any in-flight request and clear timeout\n - For SVG file uploads: call `simplifyVector()` instead of `traceImage()`\n2. Create `app/src/components/ParameterSliders.tsx`:\n - Accepts current preset config and an `onChange(params)` callback\n - Renders labeled range inputs for key parameters:\n - **Detail Level** (epsilon): range 0.5–10, step 0.5, from postprocessing.epsilon\n - **Noise Filter** (filter_speckle/turdsize): range 0–50, step 1, from vectorization params\n - **Smooth Curves** (alphamax): range 0–1.334, step 0.1, from vectorization.potrace.alphamax\n - **Corner Threshold** (corner_threshold): range 0–180, step 1, from vectorization.vtracer.corner_threshold (only shown for vtracer mode)\n - Show/hide sliders based on vectorization mode (potrace vs vtracer) from preset\n - Each slider change calls `onChange` with the full current params object\n - Show current numeric value next to each slider\n3. Create `app/src/components/SvgPreview.tsx`:\n - Accepts `svgOutput: string | null`, `isLoading: boolean`, `error: string | null`\n - When loading: show a spinner/overlay\n - When error: show error message with retry suggestion\n - When SVG available: render via `dangerouslySetInnerHTML` inside a container div\n - Strip `width` and `height` attributes from the SVG string (keep viewBox) for responsive scaling\n - Apply CSS: `width: 100%; height: auto; max-height: 70vh; object-fit: contain` on the container\n4. Wire everything in `ImportConvert.tsx`:\n - Track `currentParams` state, initialized from selected preset defaults\n - When preset changes: reset params to new preset defaults, trigger re-trace\n - When slider changes: update params, trigger re-trace via the debounced hook\n - When file changes: trigger immediate trace (no debounce for initial upload)\n - Pass svgOutput/isLoading/error to SvgPreview\n5. Write `app/src/hooks/__tests__/useDebouncedTrace.test.ts` — test the hook with mocked fetch:\n - Verify debounce behavior (multiple rapid calls → only last fires)\n - Verify abort: mock AbortController, confirm signal is passed and previous request aborted\n - Verify SVG mode detection routes to simplifyVector\n - Estimate: 1h30m\n - Files: app/src/hooks/useDebouncedTrace.ts, app/src/components/ParameterSliders.tsx, app/src/components/SvgPreview.tsx, app/src/views/ImportConvert.tsx, app/src/hooks/__tests__/useDebouncedTrace.test.ts\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [x] **T04: Created OutputInfoBar with color-coded stats, wired Use This button with disabled state, added 7 component tests — 23/23 tests pass, zero TS errors** — Complete the slice by adding the output info bar with color-coded stats, the 'Use This' button that advances to View 2, error/empty states, and a full-stack integration verification.\n\n## Steps\n\n1. Create `app/src/components/OutputInfoBar.tsx`:\n - Accepts `metadata: TraceMetadata | null`\n - When metadata is null: render nothing or a muted placeholder\n - Render stats: Path Count, Total Nodes, Open Paths, Processing Time\n - Color coding: green for normal values, yellow when node_count_total > 5000, red when open_paths > 0\n - Show warnings from metadata.warnings array if any\n2. Add 'Use This' button to `ImportConvert.tsx`:\n - Disabled when no SVG output is available\n - On click: call `onUseThis(svgOutput, metadata)` prop, which App.tsx uses to transition view state to 'canvas'\n - Pass the SVG string forward (stored in App.tsx state for S02 to consume)\n3. Add empty/error states throughout:\n - No file selected: show upload prompt in preview area\n - API error: show error message in preview area with status code\n - Loading: show spinner overlay on preview\n4. Write `app/src/components/__tests__/OutputInfoBar.test.tsx` — test color coding logic:\n - Normal metadata → green indicators\n - High node count → yellow indicator\n - Open paths > 0 → red indicator\n - Null metadata → no crash, placeholder shown\n5. Final verification: ensure `npx tsc --noEmit` passes with zero errors, `npx vitest run` passes all tests, and all components are wired together end-to-end.\n - Estimate: 45m\n - Files: app/src/components/OutputInfoBar.tsx, app/src/components/__tests__/OutputInfoBar.test.tsx, app/src/views/ImportConvert.tsx, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n\n---\n\n### Project Knowledge\nSource: `.gsd/KNOWLEDGE.md`\n\n# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit. Add entries when you discover something worth remembering.\n\n## Rules\n\n| # | Scope | Rule | Why | Added |\n|---|-------|------|-----|-------|\n\n## Patterns\n\n| # | Pattern | Where | Notes |\n|---|---------|-------|-------|\n| P001 | Test images generated programmatically via numpy | engine/tests/ | No fixture image files checked in. Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n| P003 | PostProcessResult is the universal intermediate representation | engine/pipeline/postprocess.py → engine/output/ | All output generators (DXF, JSON, SVG) consume PostProcessResult. Never generate output directly from raw SVG strings. |\n| P004 | _format_response() for consistent multi-format API responses | engine/api/routes.py | DXF returns binary Response with X-Kerf-Metadata header; SVG/JSON return JSON envelopes. Use _format_response() for both /engine/trace and /engine/simplify. |\n| P005 | Preset-driven pipeline: resolve_params() merges preset → user | engine/presets/loader.py, engine/api/routes.py | Presets define defaults for all pipeline stages. User params override. Mode comes from preset unless user explicitly sets it. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them. Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003). All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n| L007 | Docker build context must be project root, not engine/ | Dockerfile.engine uses `COPY engine/...` paths relative to project root | Always build with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` from project root | Docker |\n| L008 | Engine container has dual health endpoints | /health on root (main.py) and /engine/health on router (routes.py) both exist | Use /engine/health for Docker HEALTHCHECK and external probes for namespace consistency | engine API, Docker |\n\n---\n\n### Task Summary: T01\nSource: `.gsd/milestones/M002/slices/S01/tasks/T01-SUMMARY.md`\n\n---\nid: T01\nparent: S01\nmilestone: M002\nprovides: []\nrequires: []\naffects: []\nkey_files: [\"engine/main.py\", \"app/vite.config.ts\", \"app/src/types/engine.ts\", \"app/src/api/engine.ts\", \"app/src/api/__tests__/engine.test.ts\", \"app/src/App.tsx\", \"app/src/test-setup.ts\", \"app/tsconfig.app.json\"]\nkey_decisions: [\"Allow all CORS origins for dev with comment to restrict in production\", \"API client functions throw on non-ok responses with status + detail text\", \"Use vitest globals + jsdom environment for test ergonomics\"]\npatterns_established: []\ndrill_down_paths: []\nobservability_surfaces: []\nduration: \"\"\nverification_result: \"Ran `cd app && npx vitest run --reporter=verbose` — all 9 tests pass (3 per API function: getPresets, traceImage, simplifyVector).

that integrates with the Engine API for interactive vectorization.\n\n**T01 — Foundation:** Added CORSMiddleware to engine/main.py for browser API access. Scaffolded the app/ directory as a Vite + React + TypeScript project with a dev proxy forwarding /engine/* requests to localhost:8000. Built typed API client (getPresets, traceImage, simplifyVector) with AbortSignal support and error handling. Established the test infrastructure with Vitest + jsdom + testing-library. 9 tests pass.\n\n**T02 — UI Shell:** Created the two-column ImportConvert layout (left: controls, right: preview). Built FileUpload component with drag-and-drop + file input fallback, thumbnail preview via URL.createObjectURL, and SVG file detection for mode switching. Built PresetSelector that fetches presets from the engine API on mount with AbortController cleanup, renders preset cards with selection highlighting, and auto-selects 'sign' as default. Set up ViewState routing in App.tsx (import → canvas → export).\n\n**T03 — Core Interaction Loop (highest risk):** Created the useDebouncedTrace custom hook — the central piece — which debounces API calls on params/preset/file change, aborts in-flight requests via AbortController, and routes SVG uploads to simplifyVector() instead of traceImage(). Solved infinite re-render loops by stabilizing params via JSON.stringify in the useEffect dependency array. Built ParameterSliders with mode-aware controls (potrace shows epsilon/turdsize/alphamax; vtracer shows epsilon/filter_speckle/corner_threshold). Built SvgPreview with responsive SVG rendering (strips width/height, preserves viewBox), loading spinner, and error states. Wired the complete live re-trace loop in ImportConvert. 7 hook tests pass.\n\n**T04 — Polish & Completion:** Created OutputInfoBar with color-coded stats (green normal, yellow >5000 nodes, red open paths), warnings display, and processing time. Wired the Use This button (disabled when no SVG output) that passes SVG + metadata to App.tsx for View 2 consumption. 7 component tests pass.\n\nAll 23 tests pass.

Select a JPG file\n4. **Expected:** Same result as Test 1 — filename, size, and thumbnail displayed\n\n### Test 3: File Upload — SVG Detection\n1. Upload an SVG file (via drag or click)\n2. **Expected:** File is accepted and thumbnail/filename shown\n3. Observe that when trace fires, it calls `/engine/simplify` (not `/engine/trace`) — verify in browser devtools Network tab\n\n### Test 4: Preset Selection\n1. Upload a raster image (PNG)\n2. Verify preset cards appear below the upload zone, fetched from the engine API\n3. **Expected:** 'sign' preset is selected by default (highlighted)\n4. Click a different preset card (e.g., 'technical' or 'photo')\n5. **Expected:** The clicked preset becomes highlighted, the previous one unhighlights\n6. **Expected:** The SVG preview updates automatically after a short debounce delay\n\n### Test 5: Live Debounced Re-Trace\n1. Upload a raster PNG with the 'sign' preset selected\n2. Wait for the initial SVG preview to appear in the right panel\n3. **Expected:** Preview shows a vectorized SVG version of the uploaded image\n4. Move the \"Detail Level\" slider\n5. **Expected:** After ~300ms debounce, the preview updates with the new vectorization result\n6. Rapidly move sliders 3-4 times in quick succession\n7. **Expected:** Only the final parameter set triggers an API call (debounce coalesces rapid changes)\n\n### Test 6: Parameter Sliders — Potrace Mode\n1. Select a preset that uses potrace mode (e.g., 'sign')\n2. **Expected:** Sliders shown: Detail Level (epsilon), Noise Filter (turdsize), Smooth Curves (alphamax)\n3. **Expected:** Corner Threshold slider is NOT shown (vtracer-only)\n4. Each slider displays its current numeric value\n\n### Test 7: Parameter Sliders — VTracer Mode\n1. Select a preset that uses vtracer mode (if available)\n2. **Expected:** Sliders shown: Detail Level (epsilon), Noise Filter (filter_speckle), Corner Threshold (corner_threshold)\n3. **Expected:** Smooth Curves (alphamax) slider is NOT shown (potrace-only)\n\n### Test 8: SVG Preview — Responsive Rendering\n1. Upload an image and wait for SVG preview\n2. Resize the browser window\n3. **Expected:** SVG preview scales responsively (maintains aspect ratio, fills available width, max-height 70vh)\n4. **Expected:** No horizontal scrollbars or overflow\n\n### Test 9: Output Info Bar — Normal Stats\n1. Upload an image, wait for vectorization to complete\n2. **Expected:** Stats bar appears below the preview showing: Path Count, Total Nodes, Open Paths, Processing Time\n3. **Expected:** All indicators are green for typical images with moderate complexity\n\n### Test 10: Output Info Bar — Warning Indicators\n1. Upload a complex/detailed image that produces >5000 total nodes\n2. **Expected:** Total Nodes indicator turns yellow\n3. If the result has open paths > 0: **Expected:** Open Paths indicator turns red\n4. If engine returns warnings: **Expected:** Warnings are displayed in the info bar\n\n### Test 11: Use This Button — Disabled State\n1. Load the page fresh (no file uploaded)\n2. **Expected:** \"Use This\" button is visible but disabled/grayed out\n3. Upload a file but before the trace completes:\n4. **Expected:** Button remains disabled while loading\n\n### Test 12: Use This Button — Advances to Canvas\n1. Upload a file, wait for SVG preview to appear\n2. **Expected:** \"Use This\" button becomes enabled\n3. Click the \"Use This\" button\n4. **Expected:** View transitions from Import & Convert to the Design Canvas placeholder (shows \"View 2: Design Canvas\")\n\n### Test 13: Error Handling — API Failure\n1. Stop the engine server\n2. Upload a file\n3. **Expected:** Preview area shows an error message (not a crash or blank screen)\n4. Restart the engine\n5. Re-upload or change a slider\n6. **Expected:** Preview recovers and shows the vectorized result\n\n### Test 14: AbortController Cleanup\n1. Upload a file and immediately upload a different file before the first trace completes\n2. **Expected:** First request is aborted (visible in devtools Network tab as cancelled), second request completes normally\n3. Only the second file's result is shown in the preview\n\n### Edge Cases\n\n### Test 15: Large File Upload\n1. Upload a large image (>5MB)\n2. **Expected:** Upload completes, thumbnail shown, vectorization runs (may take longer than usual)\n3. No UI freezing during processing\n\n### Test 16: Rapid Preset Switching\n1. Upload a file, then rapidly click through 3-4 different presets\n2. **Expected:** Intermediate requests are aborted, only the final preset's result is displayed\n3. No stale results from earlier presets appear after the final result loads","verification":"All slice-level verification checks pass:\n- `cd app && npx vitest run --reporter=verbose`: 23/23 tests pass across 3 test files (9 API client, 7 OutputInfoBar, 7 useDebouncedTrace)\n- `cd app && npx tsc --noEmit`: zero TypeScript errors\n- All planned files exist: API client, types, 6 components, 1 custom hook, 2 views, CSS modules, 3 test files\n- CORS middleware confirmed in engine/main.py\n- Vite dev proxy confirmed in vite.config.ts"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":4186,"cacheRead":66866,"cacheWrite":270,"totalTokens":71323,"cost":{"input":0.000005,"output":0.10465,"cacheRead":0.033433,"cacheWrite":0.0016875,"total":0.13977550000000002}},"stopReason":"toolUse","timestamp":1774502328477}} +{"type":"message","id":"1ae21176","parentId":"85a1f3ca","timestamp":"2026-03-26T05:20:14.730Z","message":{"role":"toolResult","toolCallId":"toolu_01Y3wGDr3zCBw9E54U9nJqwu","toolName":"gsd_slice_complete","content":[{"type":"text","text":"Completed slice S01 (M002)"}],"details":{"operation":"complete_slice","sliceId":"S01","milestoneId":"M002","summaryPath":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/S01-SUMMARY.md","uatPath":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S01/S01-UAT.md"},"isError":false,"timestamp":1774502414729}} +{"type":"message","id":"b61aa2b6","parentId":"1ae21176","timestamp":"2026-03-26T05:20:16.414Z","message":{"role":"assistant","content":[{"type":"text","text":"Slice S01 complete."}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":10,"cacheRead":67136,"cacheWrite":4235,"totalTokens":71382,"cost":{"input":0.000005,"output":0.00025,"cacheRead":0.033568,"cacheWrite":0.026468750000000003,"total":0.060291750000000005}},"stopReason":"stop","timestamp":1774502414729}} +{"type":"custom_message","customType":"async_job_result","content":"**Background job done: bg_439616cd** (tsc, 0.3s)\n\n(no output)","display":true,"id":"10771e84","parentId":"b61aa2b6","timestamp":"2026-03-26T05:20:16.416Z"} +{"type":"message","id":"356e29c3","parentId":"10771e84","timestamp":"2026-03-26T05:20:19.562Z","message":{"role":"assistant","content":[{"type":"text","text":"Acknowledged — that was the TypeScript check that already completed earlier (zero errors).

View 1 integrates with the Engine API for vectorization with live preview. View 2 is a Konva.js-powered 2D design environment with artboard shapes, text objects, basic shapes, layers, alignment tools, and undo/redo.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Import & Convert UI (View 1) | medium — debounced preview updates, engine api integration from browser | — | ✅ | Upload a PNG, see live preview with preset selection and slider controls, click 'Use This' to advance to canvas |\n| S02 | Design Canvas Core (View 2) | medium — konva.js setup, selection handles, undo/redo state management | S01 | ⬜ | Create artboards in each shape, add/move/resize shapes, multi-select with alignment, undo/redo through history |\n| S03 | Text System + Font Loading | medium — opentype.js integration, font loading from volume, path extraction accuracy | S02 | ⬜ | Add text objects, select fonts from picker, change size/spacing, convert text to paths — paths match original glyphs |\n\n---\n\n### Decisions\nSource: `.gsd/DECISIONS.md`\n\n# Decisions Register\n\n\n\n| # | When | Scope | Decision | Choice | Rationale | Revisable? | Made By |\n|---|------|-------|----------|--------|-----------|------------|---------|\n| D001 | | architecture | Engine/App architectural relationship | Engine is standalone module, App is a consumer. Zero coupling — App calls Engine only via HTTP API. | Engine is proprietary IP that must be embeddable into future applications independently. Clean input/output contracts enable this. | No | human |\n| D002 | | architecture | Build order and gating strategy | Build Engine first (M001), then App canvas (M002), then Export+Deploy+Embed (M003). Human checkpoints gate each transition. | Brief explicitly mandates: validate engine output quality before building canvas UI, validate canvas before export/deploy. Engine is the hardest and most valuable piece. | No | human |\n| D003 | | engine | Post-processing replaces regex metadata extraction | postprocess_svg() pipeline replaces old _extract_svg_metadata() regex approach; all SVG paths are parsed into structured PathInfo objects with coordinates, area, island status | Structured path data is needed for DXF/JSON output generation, RDP simplification, and island detection. XML parsing is now necessary since we need actual coordinate data, not just counts. This supersedes D003's regex approach. | No | agent |\n| D004 | | architecture | Engine Docker image build strategy | Multi-stage build: builder stage compiles pypotrace with build-essential/libagg-dev/libpotrace-dev, runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl). Only engine source is copied — no App code. | Multi-stage keeps the runtime image small by excluding build tools. Copying only engine source enforces the Engine/App separation (D001). curl is included for Docker HEALTHCHECK. | Yes | agent |\n| D005 | | architecture | Frontend technology stack for Kerf App | Vite + React + TypeScript with plain CSS modules, Vitest for testing, raw fetch + FormData for engine API calls, no UI framework for V1 | Minimal dependency surface for a tool that needs fast iteration. The engine API uses multipart/form-data which works naturally with native fetch + FormData. CSS modules avoid global style conflicts without adding a framework. Vitest integrates natively with Vite's transform pipeline. No UI library needed — the app has a focused interface with ~8 components. | Yes | agent |\n| D006 | | frontend | React hook params stabilization strategy for useDebouncedTrace | JSON.stringify params in useEffect deps array, single-effect architecture | useCallback-based triggerTrace with object params caused infinite re-render loops because React creates new object references each render. JSON.stringify converts params to a stable string for dependency comparison, eliminating the need for callers to useMemo their params objects. Simpler API surface and no re-render bugs. | Yes | agent |\n\n---\n\n### Project Knowledge\nSource: `.gsd/KNOWLEDGE.md`\n\n# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit. Add entries when you discover something worth remembering.\n\n## Rules\n\n| # | Scope | Rule | Why | Added |\n|---|-------|------|-----|-------|\n\n## Patterns\n\n| # | Pattern | Where | Notes |\n|---|---------|-------|-------|\n| P001 | Test images generated programmatically via numpy | engine/tests/ | No fixture image files checked in. Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n| P003 | PostProcessResult is the universal intermediate representation | engine/pipeline/postprocess.py → engine/output/ | All output generators (DXF, JSON, SVG) consume PostProcessResult. Never generate output directly from raw SVG strings. |\n| P004 | _format_response() for consistent multi-format API responses | engine/api/routes.py | DXF returns binary Response with X-Kerf-Metadata header; SVG/JSON return JSON envelopes. Use _format_response() for both /engine/trace and /engine/simplify. |\n| P005 | Preset-driven pipeline: resolve_params() merges preset → user | engine/presets/loader.py, engine/api/routes.py | Presets define defaults for all pipeline stages. User params override. Mode comes from preset unless user explicitly sets it. |\n| P006 | JSON.stringify for React hook dependency stabilization | app/src/hooks/useDebouncedTrace.ts | Object params in useEffect deps cause infinite loops (new ref each render). Stringify the params object and use the string in the deps array. Avoids requiring callers to useMemo. |\n| P007 | Vite dev proxy for engine API calls | app/vite.config.ts | `/engine/*` requests proxy to `http://localhost:8000`. API client uses relative URLs (`/engine/presets`). No CORS issues in dev because same-origin via proxy. |\n| P008 | CSS modules for views, global App.css for shared component styles | app/src/views/*.module.css, app/src/App.css | View-specific layout in CSS modules avoids conflicts. Shared styles (upload zone, preset cards, buttons) in App.css for cross-component reuse. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them. Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003). All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n| L007 | Docker build context must be project root, not engine/ | Dockerfile.engine uses `COPY engine/...` paths relative to project root | Always build with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` from project root | Docker |\n| L008 | Engine container has dual health endpoints | /health on root (main.py) and /engine/health on router (routes.py) both exist | Use /engine/health for Docker HEALTHCHECK and external probes for namespace consistency | engine API, Docker |\n| L009 | useCallback-based triggerTrace caused infinite re-render loops | Object params create new references each render, retriggering useEffect even when values are unchanged | Restructure hook to use single useEffect with JSON.stringify(params) in dependency array instead of useCallback-based approach | app hooks, React |\n\n---\n\n# {{scope}} — Research\n\n**Date:** {{date}}\n\n\n\n## Summary\n\n{{summary — 2-3 paragraphs with primary recommendation}}\n\n## Recommendation\n\n{{whatApproachToTake_AND_why}}\n\n## Implementation Landscape\n\n\n\n### Key Files\n\n- `{{filePath}}` — {{whatItDoesAndHowItRelates}}\n- `{{filePath}}` — {{whatNeedsToChange}}\n\n### Build Order\n\n{{whatToProveOrBuildFirst_AND_why — whatUnblocksDownstreamWork}}\n\n### Verification Approach\n\n{{howToConfirmTheSliceWorks — commands, tests, observable behaviors}}\n\n\n\n## Don't Hand-Roll\n\n\n\n| Problem | Existing Solution | Why Use It |\n|---------|------------------|------------|\n| {{problem}} | {{solution}} | {{why}} |\n\n## Constraints\n\n\n\n- {{hardConstraintFromCodebaseOrRuntime}}\n- {{constraintFromDependencies}}\n\n## Common Pitfalls\n\n\n\n- **{{pitfall}}** — {{howToAvoid}}\n- **{{pitfall}}** — {{howToAvoid}}\n\n## Open Risks\n\n\n\n- {{riskThatCouldSurfaceDuringExecution}}\n\n## Skills Discovered\n\n\n\n| Technology | Skill | Status |\n|------------|-------|--------|\n| {{technology}} | {{owner/repo@skill}} | {{installed / available / none found}} |\n\n## Sources\n\n\n\n- {{whatWasLearned}} (source: [{{title}}]({{url}}))\n\n### Output Template: Research\nSource: `templates/research.md`\n\n### Dependency Slice Summaries\n\nPay particular attention to **Forward Intelligence** sections — they contain hard-won knowledge about what's fragile, what assumptions changed, and what to watch out for.\n\n#### S01 Summary\nSource: `.gsd/milestones/M002/slices/S01/S01-SUMMARY.md`\n\n---\nid: S01\nparent: M002\nmilestone: M002\nprovides:\n -

Scaffolded the app/ directory as a Vite + React + TypeScript project with a dev proxy forwarding /engine/* requests to localhost:8000. Built typed API client (getPresets, traceImage, simplifyVector) with AbortSignal support and error handling. Established the test infrastructure with Vitest + jsdom + testing-library. 9 tests pass.\n\n**T02 — UI Shell:** Created the two-column ImportConvert layout (left: controls, right: preview). Built FileUpload component with drag-and-drop + file input fallback, thumbnail preview via URL.createObjectURL, and SVG file detection for mode switching. Built PresetSelector that fetches presets from the engine API on mount with AbortController cleanup, renders preset cards with selection highlighting, and auto-selects 'sign' as default. Set up ViewState routing in App.tsx (import → canvas → export).\n\n**T03 — Core Interaction Loop (highest risk):** Created the useDebouncedTrace custom hook — the central piece — which debounces API calls on params/preset/file change, aborts in-flight requests via AbortController, and routes SVG uploads to simplifyVector() instead of traceImage(). Solved infinite re-render loops by stabilizing params via JSON.stringify in the useEffect dependency array. Built ParameterSliders with mode-aware controls (potrace shows epsilon/turdsize/alphamax; vtracer shows epsilon/filter_speckle/corner_threshold). Built SvgPreview with responsive SVG rendering (strips width/height, preserves viewBox), loading spinner, and error states. Wired the complete live re-trace loop in ImportConvert. 7 hook tests pass.\n\n**T04 — Polish & Completion:** Created OutputInfoBar with color-coded stats (green normal, yellow >5000 nodes, red open paths), warnings display, and processing time. Wired the Use This button (disabled when no SVG output) that passes SVG + metadata to App.tsx for View 2 consumption. 7 component tests pass.\n\nAll 23 tests pass. Zero TypeScript errors.\n\n## Verification\n\nAll slice-level verification checks pass:\n- `cd app && npx vitest run --reporter=verbose`: 23/23 tests pass across 3 test files (9 API client, 7 OutputInfoBar, 7 useDebouncedTrace)\n- `cd app && npx tsc --noEmit`: zero TypeScript errors\n- All planned files exist: API client, types, 6 components, 1 custom hook, 2 views, CSS modules, 3 test files\n- CORS middleware confirmed in engine/main.py\n- Vite dev proxy confirmed in vite.config.ts\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nMinor deviations, none plan-breaking:\n- T01: Added @types/node and test-setup.ts (not in plan) for proper type resolution and jest-dom matchers\n- T03: Use This button was wired in T03 instead of T04 — T04 retained it and added disabled state logic\n- T03: Hook architecture changed from useCallback-based trigger to single-useEffect with JSON.stringify params stabilization to avoid infinite re-render loops\n\n## Known Limitations\n\n- CORS allows all origins (appropriate for dev, needs restriction for production)\n- SVG preview uses dangerouslySetInnerHTML — acceptable for engine-generated SVG but should not be used for untrusted SVG in production\n- No end-to-end integration test with a running engine (unit tests mock fetch)\n\n## Follow-ups\n\n- S02 consumes the SVG string and TraceMetadata passed via onUseThis callback in App.tsx\n- Production CORS configuration should be added when deployment is set up (M003)\n- Consider adding SVG sanitization if untrusted input becomes possible\n\n## Files Created/Modified\n\n- `engine/main.py` — Added CORSMiddleware allowing all origins for dev\n- `app/vite.config.ts` — Vite config with React plugin, dev proxy to engine, Vitest config\n- `app/src/types/engine.ts` — TypeScript interfaces for PresetConfig, TraceResponse, TraceMetadata, PresetsResponse\n- `app/src/api/engine.ts` — Typed API client: getPresets(), traceImage(), simplifyVector() with AbortSignal\n- `app/src/api/__tests__/engine.test.ts` — 9 unit tests for API client covering URL/method/FormData/AbortSignal/errors\n- `app/src/hooks/useDebouncedTrace.ts` — Custom hook: debounced trace with AbortController, SVG mode detection, params stabilization\n- `app/src/hooks/__tests__/useDebouncedTrace.test.ts` — 7 tests for debounce, abort, SVG routing, error handling, cleanup\n- `app/src/views/ImportConvert.tsx` — View 1 container: two-column layout wiring FileUpload, PresetSelector, ParameterSliders, SvgPreview, OutputInfoBar, Use This button\n- `app/src/views/ImportConvert.module.css` — CSS module for ImportConvert layout\n- `app/src/components/FileUpload.tsx` — Drag-and-drop file upload with thumbnail preview and SVG detection\n- `app/src/components/PresetSelector.tsx` — Fetches presets from engine, renders cards with selection state, auto-selects sign\n- `app/src/components/ParameterSliders.tsx` — Mode-aware range sliders for vectorization parameters\n- `app/src/components/SvgPreview.tsx` — Responsive SVG rendering with loading/error states\n- `app/src/components/OutputInfoBar.tsx` — Color-coded stats bar with warnings display\n- `app/src/components/__tests__/OutputInfoBar.test.tsx` — 7 tests for color coding logic and edge cases\n- `app/src/App.tsx` — ViewState routing, SVG/metadata state for View 2 handoff\n- `app/src/App.css` — Global styles for shared components\n- `app/src/test-setup.ts` — Vitest setup with jest-dom matchers\n\n## Your Role in the Pipeline\n\nYou are the scout. After you finish, a **planner agent** reads your output in a fresh context with no memory of your exploration. It uses your findings to decompose this slice into executable tasks — deciding what files change, what order to build things, how to verify the work. Then **executor agents** build each task in isolated context windows.\n\nWrite for the planner, not for a human. The planner needs:\n- **What files exist and what they do** — so it can scope tasks to specific files\n- **Where the natural seams are** — where work divides into independent units\n- **What to build or prove first** — what's riskiest, what unblocks everything else\n- **How to verify the result** — what commands, tests, or checks confirm the slice works\n\nIf the research doc is vague, the planner will waste its context re-exploring code you already read. If it's precise, the planner can decompose immediately.\n\n## Calibrate Depth\n\nRead the slice title, the roadmap excerpt, and any milestone research above. Ask: does this slice involve unfamiliar technology, risky integration, novel architecture, or ambiguous requirements? Or is it straightforward application of known patterns to known code?\n\n- **Deep research** — new technology, unfamiliar APIs, risky integration, multiple viable approaches, or ambiguous scope. Explore broadly, look up docs, check libraries, investigate constraints. Write all template sections. This is the default when you're genuinely uncertain.\n- **Targeted research** — known technology but new to this codebase, or moderately complex integration. Explore the relevant code, check one or two libraries, identify constraints. Omit Don't Hand-Roll and Sources if nothing applies.\n- **Light research** — well-understood work using established patterns already in the codebase (wiring up existing APIs, adding standard UI components, CRUD operations, configuration changes). Read the relevant files to confirm the pattern, note any constraints, write Summary + Recommendation + Implementation Landscape. Skip the rest. A light research doc can be 15-20 lines. Don't manufacture pitfalls or risks for work that doesn't have them.\n\nAn honest \"this is straightforward, here's the pattern to follow\" is more valuable than invented complexity.\n\n## Steps\n\nResearch what this slice needs. Narrate key findings and surprises as you go — what exists, what's missing, what constrains the approach.\n0. If `REQUIREMENTS.md` was preloaded above, identify which Active requirements this slice owns or supports. Research should target these requirements — surfacing risks, unknowns, and implementation constraints that could affect whether the slice actually delivers them.\n1. Reference specific rules from loaded skills in your findings where they inform the implementation approach.\n2. **Skill Discovery (suggest):**\n Identify the key technologies, frameworks, and services this work depends on (e.g. Stripe, Clerk, Supabase, JUCE, SwiftUI).\n For each, check if a professional agent skill already exists:\n - First check `` in your system prompt — a skill may already be installed.\n - For technologies without an installed skill, run: `npx skills find \"\"`\n - Only consider skills that are **directly relevant** to core technologies — not tangentially related.\n - Evaluate results by install count and relevance to the actual work.\n - Note promising skills in your research output with their install commands, but do NOT install them.\n - The user will decide which to install.\n3. Explore relevant code for this slice's scope. For targeted exploration, use `rg`, `find`, and reads. For broad or unfamiliar subsystems, use `scout` to map the relevant area first.\n4. Use `resolve_library` / `get_library_docs` for unfamiliar libraries — skip this for libraries already used in the codebase\n5. **Web search budget:** You have a limited budget of web searches (max ~15 per session). Use them strategically — prefer `resolve_library` / `get_library_docs` for library documentation. Do NOT repeat the same or similar queries. If a search didn't find what you need, rephrase once or move on. Target 3-5 total web searches for a typical research unit.\n6. Use the **Research** output template from the inlined context above — include only sections that have real content. The template is already inlined above; do NOT attempt to read any template file from disk (there is no `templates/SLICE-RESEARCH.md` — the correct template is already present in this prompt).\n7. Call `gsd_summary_save` with `milestone_id: M002`, `slice_id: S02`, `artifact_type: \"RESEARCH\"`, and the full research markdown as `content` — the tool computes the file path and persists to both DB and disk.\n\nThe slice directory already exists at `.gsd/milestones/M002/slices/S02/`. Do NOT mkdir.\n\n**You MUST call `gsd_summary_save` with the research content before finishing.**\n\nWhen done, say: \"Slice S02 researched.\"","display":false,"id":"a2dc91dd","parentId":"e11281fd","timestamp":"2026-03-26T05:20:21.684Z"} +{"type":"message","id":"bdbfd083","parentId":"a2dc91dd","timestamp":"2026-03-26T05:20:27.193Z","message":{"role":"assistant","content":[{"type":"text","text":"\n\nI'll research what's needed for the Design Canvas Core (View 2) slice.

Render Multiple Shapes with Selection in React Konva\n\nSource: https://context7.com/konvajs/react-konva/llms.txt\n\nThis snippet demonstrates rendering various Konva shapes (Rect, Circle, Star) as React components within a Layer. It manages shape selection using React's useState hook, highlighting the stroke and strokeWidth changes upon selection.

It clears previous guide lines, calculates new snapping lines based on object bounds, draws guides, and forces the object's position to align with the guides. It requires helper functions like getLineGuideStops, getObjectSnappingEdges, getGuides, and drawGuides.\n\n```javascript\nlayer.on('dragmove', function (e) {\n // clear all previous lines on the screen\n layer.find('.guid-line').forEach((l) => l.destroy());\n\n // find possible snapping lines\n var lineGuideStops = getLineGuideStops(e.target);\n // find snapping points of current object\n var itemBounds = getObjectSnappingEdges(e.target);\n\n // now find where can we snap current object\n var guides = getGuides(lineGuideStops, itemBounds);\n\n // do nothing of no snapping\n if (!guides.length) {\n return;\n }\n\n drawGuides(guides);\n\n var absPos = e.target.absolutePosition();\n // now force object position\n guides.forEach((lg) => {\n switch (lg.orientation) {\n case 'V': {\n absPos.x = lg.lineGuide + lg.offset;\n break;\n }\n case 'H': {\n absPos.y = lg.lineGuide + lg.offset;\n break;\n }\n }\n });\n e.target.absolutePosition(absPos);\n});\n```"}],"details":{"libraryId":"/konvajs/site","query":"alignment snap guide lines shapes layer ordering zIndex","tokens":5000,"cached":false,"truncated":false,"charCount":9652},"isError":false,"timestamp":1774502459861}} +{"type":"message","id":"b223e1de","parentId":"0ba8e756","timestamp":"2026-03-26T05:20:59.863Z","message":{"role":"toolResult","toolCallId":"toolu_01QizQrLWz2ewJP49FzGYqJ2","toolName":"bash","content":[{"type":"text","text":"\n\u001b[38;5;250m███████╗██╗ ██╗██╗██╗ ██╗ ███████╗\u001b[0m\n\u001b[38;5;248m██╔════╝██║ ██╔╝██║██║ ██║ ██╔════╝\u001b[0m\n\u001b[38;5;245m███████╗█████╔╝ ██║██║ ██║ ███████╗\u001b[0m\n\u001b[38;5;243m╚════██║██╔═██╗ ██║██║ ██║ ╚════██║\u001b[0m\n\u001b[38;5;240m███████║██║ ██╗██║███████╗███████╗███████║\u001b[0m\n\u001b[38;5;238m╚══════╝╚═╝ ╚═╝╚═╝╚══════╝╚══════╝╚══════╝\u001b[0m\n\n\u001b[38;5;102mNo skills found for \"konva\"\u001b[0m\n"}],"isError":false,"timestamp":1774502459861}} +{"type":"message","id":"adf94369","parentId":"b223e1de","timestamp":"2026-03-26T05:21:09.618Z","message":{"role":"assistant","content":[{"type":"text","text":"No skills for Konva specifically.

This is a moderately complex slice with well-documented technology (react-konva has excellent examples for every feature needed), a clear handoff from S01 (SVG string + TraceMetadata in App.tsx state), and five requirements to satisfy: R013 (artboard shapes), R015 (basic shapes with selection/resize), R016 (object/layer panel), R017 (alignment tools), R018 (undo/redo).\n\nThe core risk is state management complexity — the canvas needs a central store of typed objects with undo/redo across all mutations (add, move, resize, reorder, delete, property changes). react-konva's `Transformer` component handles selection handles and resize/rotate natively; multi-select uses `tr.nodes([...])`. The official Konva docs provide React examples for every interaction pattern needed (Transformer, multi-select with rubber-band, drag-and-drop reordering, undo/redo via history stack, dash patterns for line styles, z-index layering). No custom rendering engine needed.\n\nThe imported SVG from View 1 should be rendered via `Konva.Image` from a Blob URL — this is simpler and more reliable than parsing individual SVG paths, preserves visual fidelity, and keeps the vector as a single moveable/scaleable/rotatable object on canvas. Text objects are deferred to S03. Shield and pennant artboard shapes are custom SVG path outlines rendered as Konva.Path clip masks.\n\n## Recommendation\n\n**Build in this order: state model → artboard → Konva stage with imported SVG → shape tools + selection → object panel → alignment → undo/redo.**\n\nUse a single `useCanvasState` hook (or a context + reducer) as the central state store. All canvas objects live in an array with typed discriminated unions (`type: 'rect' | 'circle' | 'ellipse' | 'line' | 'imported-svg'`). Every mutation goes through a dispatch function that records a snapshot for undo/redo. The Konva `Stage` renders objects from this store; `Transformer` handles interactive resize/rotate. The object panel reads and reorders the same store.\n\nInstall `konva` and `react-konva` as dependencies. No other new libraries needed — alignment math and undo/redo are simple enough to implement inline. Konva.js handles all 2D rendering, hit detection, drag, and transform.\n\n## Implementation Landscape\n\n### Key Files (existing)\n\n- `app/src/App.tsx` — ViewState routing (`import | canvas | export`). Currently stores `_svgResult` (string) and `_traceMetadata` (TraceMetadata) via `handleUseThis`. The `view === 'canvas'` branch renders a placeholder div that S02 replaces with ``.\n- `app/src/types/engine.ts` — TraceMetadata interface (consumed by canvas for metadata display).\n- `app/src/App.css` — Global component styles. S02 adds canvas toolbar, object panel, and artboard setup styles here.\n- `app/src/index.css` — CSS variables (--accent, --border, --bg, --text-h, etc.) and base typography. Canvas UI must use these.\n- `app/vite.config.ts` — Vite + React + Vitest config. No changes needed.\n- `app/src/test-setup.ts` — Vitest setup with jest-dom matchers. May need `canvas` mock setup for Konva in jsdom.\n\n### Key Files (new)\n\n- `app/src/types/canvas.ts` — Canvas object type definitions: `CanvasObject` discriminated union (`RectObject | CircleObject | EllipseObject | LineObject | ImportedSvgObject`), `ArtboardConfig` (shape + dimensions + units), `CanvasState` (objects array, selectedIds, artboard config, history stack).\n- `app/src/hooks/useCanvasState.ts` — Central state management hook. Manages: object CRUD, selection (single + multi), artboard config, undo/redo history. Returns state + dispatch functions. History stored as `useRef` with a step pointer (same pattern as Konva's official undo/redo example — `useRef` avoids unnecessary re-renders on history push).\n- `app/src/views/DesignCanvas.tsx` — View 2 container. Layout: top toolbar, left canvas area with Konva Stage, right object panel. Receives `svgData` and `metadata` props from App.tsx.\n- `app/src/views/DesignCanvas.module.css` — CSS module for canvas layout (follows P008 pattern).\n- `app/src/components/canvas/ArtboardSetup.tsx` — Modal/overlay shown on first entering canvas. Shape picker (rect, square, circle, oval, shield, pennant, custom), width/height inputs, units toggle (inches/mm). Produces `ArtboardConfig`.\n- `app/src/components/canvas/KonvaStage.tsx` — Wraps `` + ``. Renders artboard background shape, all canvas objects, selection `Transformer`, rubber-band selection rectangle. Handles click-to-select, shift-click multi-select, click-on-empty to deselect.\n- `app/src/components/canvas/CanvasToolbar.tsx` — Top toolbar: select tool, shape tools (rect, circle, ellipse, line), zoom controls, undo/redo buttons, grid toggle.\n- `app/src/components/canvas/ObjectPanel.tsx` — Right sidebar: lists objects by layer order (top = front), drag-to-reorder, visibility toggle (eye icon), lock toggle (lock icon), click-to-select, double-click-to-rename.\n- `app/src/components/canvas/AlignmentBar.tsx` — Appears when objects selected: align left/center/right/top/middle/bottom, distribute H/V, center on artboard.\n- `app/src/components/canvas/ShapeProperties.tsx` — Property panel for selected shape: stroke color, stroke weight, fill toggle, line style (for line objects), dimensions display.\n- `app/src/utils/artboardShapes.ts` — SVG path data for non-primitive artboard shapes (shield, pennant). Also artboard dimension presets. Pure functions, easily testable.\n- `app/src/utils/alignment.ts` — Alignment calculation functions: align, distribute, center-on-artboard. Pure math, easily testable.\n\n### Build Order\n\n**1. Foundation — types + state hook + artboard setup (highest priority, unblocks everything)**\n- Define `CanvasObject` types in `canvas.ts`\n- Build `useCanvasState` hook with add/remove/update/select/deselect/reorder + undo/redo\n- Build `ArtboardSetup` component for shape/dimension selection\n- This is the riskiest piece — state shape affects every downstream component. Get it right first.\n\n**2. Konva Stage + imported SVG rendering**\n- Install `konva` and `react-konva`\n- Build `KonvaStage` with artboard background rendering\n- Wire imported SVG from S01 as a `Konva.Image` (convert SVG string → Blob URL → Image)\n- Add selection via `Transformer`, single + multi-select, deselect on empty click\n- Wire `DesignCanvas` view into App.tsx (replace placeholder)\n\n**3. Shape tools + selection interaction**\n- Add shape creation tools (rect, circle, ellipse, line)\n- Wire toolbar buttons for tool switching\n- Implement rubber-band selection rectangle for multi-select\n- Line style variants (solid, dashed, dotted, double, centerline via dash arrays)\n\n**4. Object panel + alignment**\n- Build `ObjectPanel` with layer list, reorder, visibility, lock\n- Build `AlignmentBar` with align/distribute/center operations\n- Wire both to `useCanvasState`\n\n**5. Undo/redo + keyboard shortcuts**\n- Wire Ctrl+Z / Ctrl+Shift+Z to undo/redo\n- Undo/redo buttons in toolbar\n- Delete key removes selected objects\n\n### Verification Approach\n\n- `cd app && npx vitest run --reporter=verbose` — all tests pass (existing 23 + new)\n- `cd app && npx tsc --noEmit` — zero TypeScript errors\n- Unit tests for pure functions: `alignment.ts` (align calculations), `artboardShapes.ts` (path data generation), `useCanvasState` (add/remove/update/select/undo/redo state transitions)\n- Component tests: `ArtboardSetup` (shape selection produces correct config), `ObjectPanel` (renders object list, reorder dispatches correct action), `AlignmentBar` (button clicks dispatch alignment)\n- Konva rendering tests may require mocking `canvas` in jsdom — `jest-canvas-mock` or `vitest-canvas-mock` package, or test pure state logic separately from rendering\n- Manual visual verification: start dev server (`cd app && npm run dev`), navigate to canvas, create artboard, add shapes, verify selection handles, undo/redo\n\n## Don't Hand-Roll\n\n| Problem | Existing Solution | Why Use It |\n|---------|------------------|------------|\n| 2D canvas rendering + hit detection | `konva` + `react-konva` | Official React bindings for Konva.js. Handles all canvas rendering, event handling, drag, transform. Well-documented with React examples for every pattern we need. |\n| Selection handles (resize/rotate) | Konva `Transformer` component | Built-in to react-konva. Handles resize handles, rotation, multi-node selection, min-size constraints via `boundBoxFunc`. |\n| Multi-select rubber-band | Konva selection rectangle pattern | Official example uses `selectionRectangle.getClientRect()` + `Konva.Util.haveIntersection()` — exact pattern documented in Konva site. |\n\n## Constraints\n\n- **jsdom has no Canvas API** — Konva requires ``. Tests that import react-konva components will fail without a canvas mock (`jest-canvas-mock` or `vitest-canvas-mock`). Structure tests to isolate pure state logic (testable without canvas) from Konva rendering (needs mock or integration test).\n- **noUnusedLocals + noUnusedParameters strict** — tsconfig.app.json has these enabled. All variables and params must be used or prefixed with `_`. S01 already uses `_svgResult` and `_traceMetadata` in App.tsx — S02 removes the underscores when these are consumed.\n- **`#root` has `width: 1126px` and `border-inline`** — Canvas view needs to either work within this container or override it. Canvas should probably fill available space. Consider using `width: 100%` or adjusting root styles for the canvas view.\n- **SVG from View 1 is a raw string** — To render on Konva canvas, convert to Blob URL → Image element → `Konva.Image`. Cannot use `dangerouslySetInnerHTML` in canvas context.\n- **CSS modules for view layout, global App.css for shared components** (P008) — Follow this pattern for DesignCanvas.module.css and shared toolbar/panel styles.\n\n## Common Pitfalls\n\n- **Transformer scale vs dimensions** — When a shape is resized via Transformer, Konva applies `scaleX/scaleY` rather than changing `width/height`. On `onTransformEnd`, reset scale to 1 and multiply into width/height to keep the state model clean. This is documented in every Konva Transformer example.\n- **Undo/redo with refs vs state** — Store history in `useRef` (not `useState`) to avoid re-renders on every history push. Only the \"current state\" triggers re-renders. The official Konva undo/redo example uses this pattern.\n- **Multi-select Transformer attachment** — Must call `transformerRef.current.nodes([...nodeRefs])` in a `useEffect` when selection changes, then `getLayer().batchDraw()`. Forgetting `batchDraw` causes stale handles.\n- **Konva z-index is render order** — In react-konva, rendering order in JSX determines z-index. To reorder layers, reorder the objects array in state. Don't use Konva's imperative `moveToTop()/moveToBottom()` — let React's declarative rendering handle it.\n- **Artboard clip region** — If objects extend beyond the artboard, they should still be visible during design but clipped on export. Use Konva `Group` with `clipFunc` for the artboard boundary, or simply render the artboard outline without clipping during design.\n\n## Open Risks\n\n- **Canvas mock stability in Vitest** — `vitest-canvas-mock` or `jest-canvas-mock` may not fully cover Konva's canvas usage. If canvas mocking proves unreliable, fall back to testing only pure state/logic functions and defer Konva component tests to integration testing. This affects test coverage but not functionality.\n- **Performance with many objects** — A design with 50+ objects plus an imported SVG image could slow down Konva rendering. Mitigate by using `listening: false` on non-interactive elements (artboard background), and `perfectDrawEnabled: false` for complex shapes.

If `REQUIREMENTS.md` was preloaded above, identify which Active requirements the roadmap says this slice owns or supports. These are the requirements this plan must deliver — every owned requirement needs at least one task that directly advances it, and verification must prove the requirement is met.\n1.

Define slice-level verification — the objective stopping condition for this slice:\n - For non-trivial slices: plan actual test files with real assertions. Name the files.\n - For simple slices: executable commands or script assertions are fine.\n - If the project is non-trivial and has no test framework, the first task should set one up.\n - If this slice establishes a boundary contract, verification must exercise that contract.\n4. **For non-trivial slices only** — plan observability, proof level, and integration closure:\n - Include `Observability / Diagnostics` for backend, integration, async, stateful, or UI slices where failure diagnosis matters.\n - Fill `Proof Level` and `Integration Closure` when the slice crosses runtime boundaries or has meaningful integration concerns.\n - **Omit these sections entirely for simple slices** where they would all be \"none\" or trivially obvious.\n5. Decompose the slice into tasks, each fitting one context window. Each task needs:\n - a concrete, action-oriented title\n - the inline task entry fields defined in the plan.md template (Why / Files / Do / Verify / Done when)\n - a matching task plan file with description, steps, must-haves, verification, inputs, and expected output\n - **Inputs and Expected Output must list concrete backtick-wrapped file paths** (e.g. `` `src/types.ts` ``).

The tool inserts all tasks in the same transaction, writes to the DB, and renders `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/S02-PLAN.md` and `.gsd/milestones/M002/slices/S02/tasks/T##-PLAN.md` files automatically. Do **not** call `gsd_plan_task` separately — `gsd_plan_slice` handles task persistence. Do **not** rely on direct `PLAN.md` writes as the source of truth; the DB-backed tool is the canonical write path for slice and task planning state.\n7. **Self-audit the plan.** Walk through each check — if any fail, fix the plan files before moving on:\n - **Completion semantics:** If every task were completed exactly as written, the slice goal/demo should actually be true.\n - **Requirement coverage:** Every must-have in the slice maps to at least one task. No must-have is orphaned. If `REQUIREMENTS.md` exists, every Active requirement this slice owns maps to at least one task.\n - **Task completeness:** Every task has steps, must-haves, verification, inputs, and expected output — none are blank or vague. Inputs and Expected Output list backtick-wrapped file paths, not prose descriptions.\n - **Dependency correctness:** Task ordering is consistent. No task references work from a later task.\n - **Key links planned:** For every pair of artifacts that must connect, there is an explicit step that wires them.\n - **Scope sanity:** Target 2–5 steps and 3–8 files per task. 10+ steps or 12+ files — must split. Each task must be completable in a single fresh context window.\n - **Feature completeness:** Every task produces real, user-facing progress — not just internal scaffolding.\n10.

View 1 integrates with the Engine API for vectorization with live preview. View 2 is a Konva.js-powered 2D design environment with artboard shapes, text objects, basic shapes, layers, alignment tools, and undo/redo.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Import & Convert UI (View 1) | medium — debounced preview updates, engine api integration from browser | — | ✅ | Upload a PNG, see live preview with preset selection and slider controls, click 'Use This' to advance to canvas |\n| S02 | Design Canvas Core (View 2) | medium — konva.js setup, selection handles, undo/redo state management | S01 | ⬜ | Create artboards in each shape, add/move/resize shapes, multi-select with alignment, undo/redo through history |\n| S03 | Text System + Font Loading | medium — opentype.js integration, font loading from volume, path extraction accuracy | S02 | ⬜ | Add text objects, select fonts from picker, change size/spacing, convert text to paths — paths match original glyphs |\n\n---\n\n### Slice Research\nSource: `.gsd/milestones/M002/slices/S02/S02-RESEARCH.md`\n\n# S02 — Design Canvas Core (View 2) — Research\n\n**Date:** 2026-03-26\n\n## Summary\n\nS02 builds View 2, the Konva.js-powered 2D design canvas. This is a moderately complex slice with well-documented technology (react-konva has excellent examples for every feature needed), a clear handoff from S01 (SVG string + TraceMetadata in App.tsx state), and five requirements to satisfy: R013 (artboard shapes), R015 (basic shapes with selection/resize), R016 (object/layer panel), R017 (alignment tools), R018 (undo/redo).\n\nThe core risk is state management complexity — the canvas needs a central store of typed objects with undo/redo across all mutations (add, move, resize, reorder, delete, property changes). react-konva's `Transformer` component handles selection handles and resize/rotate natively; multi-select uses `tr.nodes([...])`. The official Konva docs provide React examples for every interaction pattern needed (Transformer, multi-select with rubber-band, drag-and-drop reordering, undo/redo via history stack, dash patterns for line styles, z-index layering). No custom rendering engine needed.\n\nThe imported SVG from View 1 should be rendered via `Konva.Image` from a Blob URL — this is simpler and more reliable than parsing individual SVG paths, preserves visual fidelity, and keeps the vector as a single moveable/scaleable/rotatable object on canvas. Text objects are deferred to S03. Shield and pennant artboard shapes are custom SVG path outlines rendered as Konva.Path clip masks.\n\n## Recommendation\n\n**Build in this order: state model → artboard → Konva stage with imported SVG → shape tools + selection → object panel → alignment → undo/redo.**\n\nUse a single `useCanvasState` hook (or a context + reducer) as the central state store. All canvas objects live in an array with typed discriminated unions (`type: 'rect' | 'circle' | 'ellipse' | 'line' | 'imported-svg'`). Every mutation goes through a dispatch function that records a snapshot for undo/redo. The Konva `Stage` renders objects from this store; `Transformer` handles interactive resize/rotate. The object panel reads and reorders the same store.\n\nInstall `konva` and `react-konva` as dependencies. No other new libraries needed — alignment math and undo/redo are simple enough to implement inline. Konva.js handles all 2D rendering, hit detection, drag, and transform.\n\n## Implementation Landscape\n\n### Key Files (existing)\n\n- `app/src/App.tsx` — ViewState routing (`import | canvas | export`). Currently stores `_svgResult` (string) and `_traceMetadata` (TraceMetadata) via `handleUseThis`. The `view === 'canvas'` branch renders a placeholder div that S02 replaces with ``.\n- `app/src/types/engine.ts` — TraceMetadata interface (consumed by canvas for metadata display).\n- `app/src/App.css` — Global component styles. S02 adds canvas toolbar, object panel, and artboard setup styles here.\n- `app/src/index.css` — CSS variables (--accent, --border, --bg, --text-h, etc.) and base typography. Canvas UI must use these.\n- `app/vite.config.ts` — Vite + React + Vitest config. No changes needed.\n- `app/src/test-setup.ts` — Vitest setup with jest-dom matchers. May need `canvas` mock setup for Konva in jsdom.\n\n### Key Files (new)\n\n- `app/src/types/canvas.ts` — Canvas object type definitions: `CanvasObject` discriminated union (`RectObject | CircleObject | EllipseObject | LineObject | ImportedSvgObject`), `ArtboardConfig` (shape + dimensions + units), `CanvasState` (objects array, selectedIds, artboard config, history stack).\n- `app/src/hooks/useCanvasState.ts` — Central state management hook. Manages: object CRUD, selection (single + multi), artboard config, undo/redo history. Returns state + dispatch functions. History stored as `useRef` with a step pointer (same pattern as Konva's official undo/redo example — `useRef` avoids unnecessary re-renders on history push).\n- `app/src/views/DesignCanvas.tsx` — View 2 container. Layout: top toolbar, left canvas area with Konva Stage, right object panel. Receives `svgData` and `metadata` props from App.tsx.\n- `app/src/views/DesignCanvas.module.css` — CSS module for canvas layout (follows P008 pattern).\n- `app/src/components/canvas/ArtboardSetup.tsx` — Modal/overlay shown on first entering canvas. Shape picker (rect, square, circle, oval, shield, pennant, custom), width/height inputs, units toggle (inches/mm). Produces `ArtboardConfig`.\n- `app/src/components/canvas/KonvaStage.tsx` — Wraps `` + ``. Renders artboard background shape, all canvas objects, selection `Transformer`, rubber-band selection rectangle. Handles click-to-select, shift-click multi-select, click-on-empty to deselect.\n- `app/src/components/canvas/CanvasToolbar.tsx` — Top toolbar: select tool, shape tools (rect, circle, ellipse, line), zoom controls, undo/redo buttons, grid toggle.\n- `app/src/components/canvas/ObjectPanel.tsx` — Right sidebar: lists objects by layer order (top = front), drag-to-reorder, visibility toggle (eye icon), lock toggle (lock icon), click-to-select, double-click-to-rename.\n- `app/src/components/canvas/AlignmentBar.tsx` — Appears when objects selected: align left/center/right/top/middle/bottom, distribute H/V, center on artboard.\n- `app/src/components/canvas/ShapeProperties.tsx` — Property panel for selected shape: stroke color, stroke weight, fill toggle, line style (for line objects), dimensions display.\n- `app/src/utils/artboardShapes.ts` — SVG path data for non-primitive artboard shapes (shield, pennant). Also artboard dimension presets. Pure functions, easily testable.\n- `app/src/utils/alignment.ts` — Alignment calculation functions: align, distribute, center-on-artboard. Pure math, easily testable.\n\n### Build Order\n\n**1. Foundation — types + state hook + artboard setup (highest priority, unblocks everything)**\n- Define `CanvasObject` types in `canvas.ts`\n- Build `useCanvasState` hook with add/remove/update/select/deselect/reorder + undo/redo\n- Build `ArtboardSetup` component for shape/dimension selection\n- This is the riskiest piece — state shape affects every downstream component. Get it right first.\n\n**2. Konva Stage + imported SVG rendering**\n- Install `konva` and `react-konva`\n- Build `KonvaStage` with artboard background rendering\n- Wire imported SVG from S01 as a `Konva.Image` (convert SVG string → Blob URL → Image)\n- Add selection via `Transformer`, single + multi-select, deselect on empty click\n- Wire `DesignCanvas` view into App.tsx (replace placeholder)\n\n**3. Shape tools + selection interaction**\n- Add shape creation tools (rect, circle, ellipse, line)\n- Wire toolbar buttons for tool switching\n- Implement rubber-band selection rectangle for multi-select\n- Line style variants (solid, dashed, dotted, double, centerline via dash arrays)\n\n**4. Object panel + alignment**\n- Build `ObjectPanel` with layer list, reorder, visibility, lock\n- Build `AlignmentBar` with align/distribute/center operations\n- Wire both to `useCanvasState`\n\n**5. Undo/redo + keyboard shortcuts**\n- Wire Ctrl+Z / Ctrl+Shift+Z to undo/redo\n- Undo/redo buttons in toolbar\n- Delete key removes selected objects\n\n### Verification Approach\n\n- `cd app && npx vitest run --reporter=verbose` — all tests pass (existing 23 + new)\n- `cd app && npx tsc --noEmit` — zero TypeScript errors\n- Unit tests for pure functions: `alignment.ts` (align calculations), `artboardShapes.ts` (path data generation), `useCanvasState` (add/remove/update/select/undo/redo state transitions)\n- Component tests: `ArtboardSetup` (shape selection produces correct config), `ObjectPanel` (renders object list, reorder dispatches correct action), `AlignmentBar` (button clicks dispatch alignment)\n- Konva rendering tests may require mocking `canvas` in jsdom — `jest-canvas-mock` or `vitest-canvas-mock` package, or test pure state logic separately from rendering\n- Manual visual verification: start dev server (`cd app && npm run dev`), navigate to canvas, create artboard, add shapes, verify selection handles, undo/redo\n\n## Don't Hand-Roll\n\n| Problem | Existing Solution | Why Use It |\n|---------|------------------|------------|\n| 2D canvas rendering + hit detection | `konva` + `react-konva` | Official React bindings for Konva.js. Handles all canvas rendering, event handling, drag, transform. Well-documented with React examples for every pattern we need. |\n| Selection handles (resize/rotate) | Konva `Transformer` component | Built-in to react-konva. Handles resize handles, rotation, multi-node selection, min-size constraints via `boundBoxFunc`. |\n| Multi-select rubber-band | Konva selection rectangle pattern | Official example uses `selectionRectangle.getClientRect()` + `Konva.Util.haveIntersection()` — exact pattern documented in Konva site. |\n\n## Constraints\n\n- **jsdom has no Canvas API** — Konva requires ``. Tests that import react-konva components will fail without a canvas mock (`jest-canvas-mock` or `vitest-canvas-mock`). Structure tests to isolate pure state logic (testable without canvas) from Konva rendering (needs mock or integration test).\n- **noUnusedLocals + noUnusedParameters strict** — tsconfig.app.json has these enabled. All variables and params must be used or prefixed with `_`. S01 already uses `_svgResult` and `_traceMetadata` in App.tsx — S02 removes the underscores when these are consumed.\n- **`#root` has `width: 1126px` and `border-inline`** — Canvas view needs to either work within this container or override it. Canvas should probably fill available space. Consider using `width: 100%` or adjusting root styles for the canvas view.\n- **SVG from View 1 is a raw string** — To render on Konva canvas, convert to Blob URL → Image element → `Konva.Image`. Cannot use `dangerouslySetInnerHTML` in canvas context.\n- **CSS modules for view layout, global App.css for shared components** (P008) — Follow this pattern for DesignCanvas.module.css and shared toolbar/panel styles.\n\n## Common Pitfalls\n\n- **Transformer scale vs dimensions** — When a shape is resized via Transformer, Konva applies `scaleX/scaleY` rather than changing `width/height`. On `onTransformEnd`, reset scale to 1 and multiply into width/height to keep the state model clean. This is documented in every Konva Transformer example.\n- **Undo/redo with refs vs state** — Store history in `useRef` (not `useState`) to avoid re-renders on every history push. Only the \"current state\" triggers re-renders. The official Konva undo/redo example uses this pattern.\n- **Multi-select Transformer attachment** — Must call `transformerRef.current.nodes([...nodeRefs])` in a `useEffect` when selection changes, then `getLayer().batchDraw()`. Forgetting `batchDraw` causes stale handles.\n- **Konva z-index is render order** — In react-konva, rendering order in JSX determines z-index. To reorder layers, reorder the objects array in state. Don't use Konva's imperative `moveToTop()/moveToBottom()` — let React's declarative rendering handle it.\n- **Artboard clip region** — If objects extend beyond the artboard, they should still be visible during design but clipped on export. Use Konva `Group` with `clipFunc` for the artboard boundary, or simply render the artboard outline without clipping during design.\n\n## Open Risks\n\n- **Canvas mock stability in Vitest** — `vitest-canvas-mock` or `jest-canvas-mock` may not fully cover Konva's canvas usage. If canvas mocking proves unreliable, fall back to testing only pure state/logic functions and defer Konva component tests to integration testing. This affects test coverage but not functionality.\n- **Performance with many objects** — A design with 50+ objects plus an imported SVG image could slow down Konva rendering. Mitigate by using `listening: false` on non-interactive elements (artboard background), and `perfectDrawEnabled: false` for complex shapes. Not expected to be an issue for typical sign/patch designs (5-20 objects).\n- **Shield/pennant artboard shapes** — These are custom clip paths. Need to define SVG path data that looks right at arbitrary aspect ratios. Shield is straightforward (symmetrical arch-top shape). Pennant is a triangle/banner shape. If aspect ratio distortion is problematic, constrain proportions.\n\n## Sources\n\n- Konva.js Transformer + multi-select: official docs (context7: /konvajs/site) — selection rectangle, shift-click, `tr.nodes([...])`\n- Konva.js undo/redo: official docs (context7: /konvajs/site) — `useRef` history pattern with step pointer\n- react-konva Transformer component: official docs (context7: /konvajs/react-konva) — `onTransformEnd` scale reset pattern\n- Konva.js dash arrays for line styles: official docs — `line.dash([10, 5])` for dashed, `[10, 20, 0.001, 20]` for dot-dash\n- Konva.js SVG on canvas: official docs — `Konva.Image.fromURL()` for SVG rendering, `Konva.Path` for individual SVG paths\n- Konva.js layering: official docs — render order in JSX determines z-index, `zIndex()` for imperative control\n\n---\n\n### Decisions\nSource: `.gsd/DECISIONS.md`\n\n# Decisions Register\n\n\n\n| # | When | Scope | Decision | Choice | Rationale | Revisable? | Made By |\n|---|------|-------|----------|--------|-----------|------------|---------|\n| D001 | | architecture | Engine/App architectural relationship | Engine is standalone module, App is a consumer.

Human checkpoints gate each transition. | Brief explicitly mandates: validate engine output quality before building canvas UI, validate canvas before export/deploy. Engine is the hardest and most valuable piece. | No | human |\n| D003 | | engine | Post-processing replaces regex metadata extraction | postprocess_svg() pipeline replaces old _extract_svg_metadata() regex approach; all SVG paths are parsed into structured PathInfo objects with coordinates, area, island status | Structured path data is needed for DXF/JSON output generation, RDP simplification, and island detection. XML parsing is now necessary since we need actual coordinate data, not just counts. This supersedes D003's regex approach. | No | agent |\n| D004 | | architecture | Engine Docker image build strategy | Multi-stage build: builder stage compiles pypotrace with build-essential/libagg-dev/libpotrace-dev, runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl). Only engine source is copied — no App code. | Multi-stage keeps the runtime image small by excluding build tools. Copying only engine source enforces the Engine/App separation (D001). curl is included for Docker HEALTHCHECK. | Yes | agent |\n| D005 | | architecture | Frontend technology stack for Kerf App | Vite + React + TypeScript with plain CSS modules, Vitest for testing, raw fetch + FormData for engine API calls, no UI framework for V1 | Minimal dependency surface for a tool that needs fast iteration. The engine API uses multipart/form-data which works naturally with native fetch + FormData. CSS modules avoid global style conflicts without adding a framework. Vitest integrates natively with Vite's transform pipeline.

Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n| P003 | PostProcessResult is the universal intermediate representation | engine/pipeline/postprocess.py → engine/output/ | All output generators (DXF, JSON, SVG) consume PostProcessResult. Never generate output directly from raw SVG strings. |\n| P004 | _format_response() for consistent multi-format API responses | engine/api/routes.py | DXF returns binary Response with X-Kerf-Metadata header; SVG/JSON return JSON envelopes.

User params override. Mode comes from preset unless user explicitly sets it. |\n| P006 | JSON.stringify for React hook dependency stabilization | app/src/hooks/useDebouncedTrace.ts | Object params in useEffect deps cause infinite loops (new ref each render). Stringify the params object and use the string in the deps array. Avoids requiring callers to useMemo. |\n| P007 | Vite dev proxy for engine API calls | app/vite.config.ts | `/engine/*` requests proxy to `http://localhost:8000`.

Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003). All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n| L007 | Docker build context must be project root, not engine/ | Dockerfile.engine uses `COPY engine/...` paths relative to project root | Always build with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` from project root | Docker |\n| L008 | Engine container has dual health endpoints | /health on root (main.py) and /engine/health on router (routes.py) both exist | Use /engine/health for Docker HEALTHCHECK and external probes for namespace consistency | engine API, Docker |\n| L009 | useCallback-based triggerTrace caused infinite re-render loops | Object params create new references each render, retriggering useEffect even when values are unchanged | Restructure hook to use single useEffect with JSON.stringify(params) in dependency array instead of useCallback-based approach | app hooks, React |\n\n---\n\n# {{sliceId}}: {{sliceTitle}}\n\n**Goal:** {{goal}}\n**Demo:** {{demo}}\n\n## Must-Haves\n\n- {{mustHave}}\n- {{mustHave}}\n\n## Proof Level\n\n\n\n- This slice proves: {{contract | integration | operational | final-assembly}}\n- Real runtime required: {{yes/no}}\n- Human/UAT required: {{yes/no}}\n\n## Verification\n\n\n\n- {{testFileOrCommand — e.g. `npm test -- --grep \"auth flow\"` or `bash scripts/verify-s01.sh`}}\n- {{testFileOrCommand}}\n\n## Observability / Diagnostics\n\n\n\n- Runtime signals: {{structured log/event, state transition, metric, or none}}\n- Inspection surfaces: {{status endpoint, CLI command, script, UI state, DB table, or none}}\n- Failure visibility: {{last error, retry count, phase, timestamp, correlation id, or none}}\n- Redaction constraints: {{secret/PII boundary or none}}\n\n## Integration Closure\n\n\n\n- Upstream surfaces consumed: {{specific files / modules / contracts}}\n- New wiring introduced in this slice: {{entrypoint / composition / runtime hookup, or none}}\n- What remains before the milestone is truly usable end-to-end: {{list or \"nothing\"}}\n\n## Tasks\n\n\n\n- [ ] **T01: {{taskTitle}}** `est:{{estimate}}`\n -

Scaffolded the app/ directory as a Vite + React + TypeScript project with a dev proxy forwarding /engine/* requests to localhost:8000. Built typed API client (getPresets, traceImage, simplifyVector) with AbortSignal support and error handling. Established the test infrastructure with Vitest + jsdom + testing-library. 9 tests pass.\n\n**T02 — UI Shell:** Created the two-column ImportConvert layout (left: controls, right: preview). Built FileUpload component with drag-and-drop + file input fallback, thumbnail preview via URL.createObjectURL, and SVG file detection for mode switching. Built PresetSelector that fetches presets from the engine API on mount with AbortController cleanup, renders preset cards with selection highlighting, and auto-selects 'sign' as default. Set up ViewState routing in App.tsx (import → canvas → export).\n\n**T03 — Core Interaction Loop (highest risk):** Created the useDebouncedTrace custom hook — the central piece — which debounces API calls on params/preset/file change, aborts in-flight requests via AbortController, and routes SVG uploads to simplifyVector() instead of traceImage(). Solved infinite re-render loops by stabilizing params via JSON.stringify in the useEffect dependency array. Built ParameterSliders with mode-aware controls (potrace shows epsilon/turdsize/alphamax; vtracer shows epsilon/filter_speckle/corner_threshold). Built SvgPreview with responsive SVG rendering (strips width/height, preserves viewBox), loading spinner, and error states. Wired the complete live re-trace loop in ImportConvert. 7 hook tests pass.\n\n**T04 — Polish & Completion:** Created OutputInfoBar with color-coded stats (green normal, yellow >5000 nodes, red open paths), warnings display, and processing time. Wired the Use This button (disabled when no SVG output) that passes SVG + metadata to App.tsx for View 2 consumption. 7 component tests pass.\n\nAll 23 tests pass. Zero TypeScript errors.\n\n## Verification\n\nAll slice-level verification checks pass:\n- `cd app && npx vitest run --reporter=verbose`: 23/23 tests pass across 3 test files (9 API client, 7 OutputInfoBar, 7 useDebouncedTrace)\n- `cd app && npx tsc --noEmit`: zero TypeScript errors\n- All planned files exist: API client, types, 6 components, 1 custom hook, 2 views, CSS modules, 3 test files\n- CORS middleware confirmed in engine/main.py\n- Vite dev proxy confirmed in vite.config.ts\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nMinor deviations, none plan-breaking:\n- T01: Added @types/node and test-setup.ts (not in plan) for proper type resolution and jest-dom matchers\n- T03: Use This button was wired in T03 instead of T04 — T04 retained it and added disabled state logic\n- T03: Hook architecture changed from useCallback-based trigger to single-useEffect with JSON.stringify params stabilization to avoid infinite re-render loops\n\n## Known Limitations\n\n- CORS allows all origins (appropriate for dev, needs restriction for production)\n- SVG preview uses dangerouslySetInnerHTML — acceptable for engine-generated SVG but should not be used for untrusted SVG in production\n- No end-to-end integration test with a running engine (unit tests mock fetch)\n\n## Follow-ups\n\n- S02 consumes the SVG string and TraceMetadata passed via onUseThis callback in App.tsx\n- Production CORS configuration should be added when deployment is set up (M003)\n- Consider adding SVG sanitization if untrusted input becomes possible\n\n## Files Created/Modified\n\n- `engine/main.py` — Added CORSMiddleware allowing all origins for dev\n- `app/vite.config.ts` — Vite config with React plugin, dev proxy to engine, Vitest config\n- `app/src/types/engine.ts` — TypeScript interfaces for PresetConfig, TraceResponse, TraceMetadata, PresetsResponse\n- `app/src/api/engine.ts` — Typed API client: getPresets(), traceImage(), simplifyVector() with AbortSignal\n- `app/src/api/__tests__/engine.test.ts` — 9 unit tests for API client covering URL/method/FormData/AbortSignal/errors\n- `app/src/hooks/useDebouncedTrace.ts` — Custom hook: debounced trace with AbortController, SVG mode detection, params stabilization\n- `app/src/hooks/__tests__/useDebouncedTrace.test.ts` — 7 tests for debounce, abort, SVG routing, error handling, cleanup\n- `app/src/views/ImportConvert.tsx` — View 1 container: two-column layout wiring FileUpload, PresetSelector, ParameterSliders, SvgPreview, OutputInfoBar, Use This button\n- `app/src/views/ImportConvert.module.css` — CSS module for ImportConvert layout\n- `app/src/components/FileUpload.tsx` — Drag-and-drop file upload with thumbnail preview and SVG detection\n- `app/src/components/PresetSelector.tsx` — Fetches presets from engine, renders cards with selection state, auto-selects sign\n- `app/src/components/ParameterSliders.tsx` — Mode-aware range sliders for vectorization parameters\n- `app/src/components/SvgPreview.tsx` — Responsive SVG rendering with loading/error states\n- `app/src/components/OutputInfoBar.tsx` — Color-coded stats bar with warnings display\n- `app/src/components/__tests__/OutputInfoBar.test.tsx` — 7 tests for color coding logic and edge cases\n- `app/src/App.tsx` — ViewState routing, SVG/metadata state for View 2 handoff\n- `app/src/App.css` — Global styles for shared components\n- `app/src/test-setup.ts` — Vitest setup with jest-dom matchers\n\n## Your Role in the Pipeline\n\nYou have full tool access. Before decomposing, explore the relevant code to ground your plan in reality.\n\n### Verify Roadmap Assumptions\n\nCheck prior slice summaries (inlined above as dependency summaries, if present). If prior slices discovered constraints, changed approaches, or flagged fragility, adjust your plan accordingly. The roadmap description may be stale — verify it against the current codebase state.\n\n### Explore Slice Scope\n\nRead the code files relevant to this slice. Confirm the roadmap's description of what exists, what needs to change, and what boundaries apply. Use `rg`, `find`, and targeted reads.\n\n### Source Files\n\n- **Decisions**: `.gsd/DECISIONS.md`\n- **Roadmap**: `.gsd/milestones/M002/M002-ROADMAP.md`\n- **Slice Research**: `.gsd/milestones/M002/slices/S02/S02-RESEARCH.md`\n\nIf slice research exists (inlined above), trust those findings and skip redundant exploration.\n\nAfter you finish, **executor agents** implement each task in isolated fresh context windows. They see only their task plan, the slice plan excerpt (goal/demo/verification), and compressed summaries of prior tasks. They do not see the research doc, the roadmap, or REQUIREMENTS.md. Everything an executor needs must be in the task plan itself — file paths, specific steps, expected inputs and outputs.\n\nNarrate your decomposition reasoning — why you're grouping work this way, what risks are driving the order, what verification strategy you're choosing and why. Keep the narration proportional to the work — a simple slice doesn't need a long justification — but write in complete sentences, not planner shorthand.\n\n**Right-size the plan.** If the slice is simple enough to be 1 task, plan 1 task. Don't split into multiple tasks just because you can identify sub-steps. Don't fill in sections with \"None\" when the section doesn't apply — omit them entirely. The plan's job is to guide execution, not to fill a template.\n","display":false,"id":"ff7a3bae","parentId":"e53589f5","timestamp":"2026-03-26T05:23:53.421Z"} +{"type":"message","id":"f25bc3fb","parentId":"ff7a3bae","timestamp":"2026-03-26T05:23:57.881Z","message":{"role":"assistant","content":[{"type":"text","text":"\n\nI'll start by reading the templates and exploring the current codebase state to ground the plan in reality."},{"type":"toolCall","id":"toolu_013viiPWznqMDgMn3JbDobjA","name":"read","arguments":{"path":"~/.gsd/agent/extensions/gsd/templates/plan.md"}},{"type":"toolCall","id":"toolu_01X21KmjDRx4hByqetv1V1ku","name":"read","arguments":{"path":"~/.gsd/agent/extensions/gsd/templates/task-plan.md"}},{"type":"toolCall","id":"toolu_01AnwT5NC9SEybjC8TviTA2G","name":"read","arguments":{"path":"app/src/App.tsx"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":2,"output":183,"cacheRead":49688,"cacheWrite":12139,"totalTokens":62012,"cost":{"input":0.00001,"output":0.004575,"cacheRead":0.024843999999999998,"cacheWrite":0.07586875,"total":0.10529775}},"stopReason":"toolUse","timestamp":1774502633419}} +{"type":"message","id":"c14be7bc","parentId":"f25bc3fb","timestamp":"2026-03-26T05:23:57.884Z","message":{"role":"toolResult","toolCallId":"toolu_013viiPWznqMDgMn3JbDobjA","toolName":"read","content":[{"type":"text","text":"# {{sliceId}}: {{sliceTitle}}\n\n**Goal:** {{goal}}\n**Demo:** {{demo}}\n\n## Must-Haves\n\n- {{mustHave}}\n- {{mustHave}}\n\n## Proof Level\n\n\n\n- This slice proves: {{contract | integration | operational | final-assembly}}\n- Real runtime required: {{yes/no}}\n- Human/UAT required: {{yes/no}}\n\n## Verification\n\n\n\n- {{testFileOrCommand — e.g. `npm test -- --grep \"auth flow\"` or `bash scripts/verify-s01.sh`}}\n- {{testFileOrCommand}}\n\n## Observability / Diagnostics\n\n\n\n- Runtime signals: {{structured log/event, state transition, metric, or none}}\n- Inspection surfaces: {{status endpoint, CLI command, script, UI state, DB table, or none}}\n- Failure visibility: {{last error, retry count, phase, timestamp, correlation id, or none}}\n- Redaction constraints: {{secret/PII boundary or none}}\n\n## Integration Closure\n\n\n\n- Upstream surfaces consumed: {{specific files / modules / contracts}}\n- New wiring introduced in this slice: {{entrypoint / composition / runtime hookup, or none}}\n- What remains before the milestone is truly usable end-to-end: {{list or \"nothing\"}}\n\n## Tasks\n\n\n\n- [ ] **T01: {{taskTitle}}** `est:{{estimate}}`\n -

Now I have full context. Let me reason through the decomposition.\n\n## Decomposition Reasoning\n\nThis slice builds the Design Canvas (View 2) — a Konva.js-powered 2D design environment. The research doc is thorough and I've verified the codebase state. Here's my thinking:\n\n**Core risk:** State management (useCanvasState) is the foundation — everything depends on it. Getting the type model and state hook right first is critical. Konva rendering, toolbar, object panel, alignment, and undo/redo all consume this hook.\n\n**Testing strategy:** Konva requires `` which jsdom doesn't have. I'll install `jest-canvas-mock` to handle this, but the primary testing strategy is: (1) unit test pure functions (alignment math, artboard shapes), (2) unit test the state hook (add/remove/update/select/undo/redo — no canvas needed), (3) component tests for non-Konva components (ArtboardSetup, ObjectPanel, AlignmentBar). Konva rendering is verified manually via dev server.\n\n**Task decomposition (4 tasks):**\n\n1. **T01: Foundation — types, state hook, artboard setup, canvas mock** — Defines the type model, builds the central state hook with full undo/redo, artboard setup component, and installs canvas mock + konva deps. This is the riskiest piece and unblocks everything. Includes pure function tests for artboard shapes and state hook tests.\n\n2. **T02: Konva stage with imported SVG, selection handles, and shape tools** — Installs react-konva, builds the KonvaStage with artboard rendering, imported SVG as Konva.Image, Transformer for selection, rubber-band multi-select, and shape creation tools (rect, circle, ellipse, line). Wires DesignCanvas view into App.tsx replacing the placeholder.\n\n3. **T03: Object panel, alignment bar, and toolbar** — Builds the ObjectPanel (layer list, reorder, visibility, lock), AlignmentBar (align/distribute/center), CanvasToolbar (tool switching, zoom, undo/redo buttons, grid toggle). Tests for alignment math and component rendering.\n\n4. **T04: Undo/redo wiring, keyboard shortcuts, and shape properties** — Wires Ctrl+Z/Ctrl+Shift+Z, Delete key, ShapeProperties panel for selected object editing. Final integration verification.\n\nThis is 4 tasks which is within the 2-6 range.

The research doc mentions R013-R018 but these aren't in a formal requirements file. All must-haves from the success criteria map to tasks:\n - Artboard setup → T01 (ArtboardSetup component)\n - Konva canvas + imported SVG → T02\n - Shape tools + selection → T02\n - Object panel → T03\n - Alignment → T03\n - Toolbar → T03\n - Shape properties → T03\n - Undo/redo + keyboard shortcuts → T01 (state hook), T03 (buttons), T04 (keyboard wiring)\n ✅\n\n3. **Task completeness:** Every task has description, steps, files, verify commands, inputs (with backtick paths), and expected outputs (with backtick paths). ✅\n\n4. **Dependency correctness:** T01 → T02 → T03 → T04 is sequential, each consumes outputs from prior tasks. No forward references. ✅\n\n5. **Key links planned:** App.tsx ↔ DesignCanvas (T02), useCanvasState ↔ all panels (T02/T03), alignment utils ↔ AlignmentBar (T03), keyboard shortcuts ↔ state hook (T04).

All within limits. ✅\n\n7. **Feature completeness:** Each task produces real user-facing progress (T01: setup modal, T02: working canvas, T03: panels, T04: keyboard shortcuts). ✅\n\nThe plan looks solid.

This is the riskiest piece — the state model shape affects every downstream component.\n\nThe useCanvasState hook is a useReducer + useRef pattern: current state in a reducer (triggers re-renders), history stack in a useRef (avoids re-renders on history push). Every mutation dispatches through the reducer which also pushes a history snapshot. Undo/redo pops from history.\n\nThe ArtboardSetup component renders a modal overlay on first entering the canvas view with shape picker (rect, square, circle, oval, shield, pennant, custom), width/height number inputs, and inches/mm units toggle. On confirm, it produces an ArtboardConfig that initializes the canvas.\n\nInstall konva, react-konva, and jest-canvas-mock as dependencies.

Layout: top toolbar area, left canvas with KonvaStage, right panel area (wired in T03). Receives svgData and traceMetadata props from App.tsx.\n- Wire DesignCanvas into App.tsx replacing the placeholder div. Remove underscore prefixes from _svgResult and _traceMetadata variables.\n- KonvaStage renders: (1) artboard background shape using Konva.Rect/Path/Circle based on ArtboardConfig, (2) all canvas objects from useCanvasState mapped to Konva components, (3) Transformer attached to selected nodes, (4) rubber-band selection rectangle for multi-select.\n- Imported SVG from View 1: convert SVG string → Blob URL → Image element → Konva.Image. Auto-add to canvas objects on mount if svgData is provided.\n- Shape tools: rect, circle, ellipse, line creation. Click canvas in tool mode to place shape at click position with default dimensions. Tool state tracked in DesignCanvas.\n- Selection: click shape to select (single), shift-click to add to selection, click empty area to deselect, rubber-band rectangle selects all intersecting shapes.\n- Transformer: on onTransformEnd, reset scaleX/scaleY to 1 and multiply into width/height to keep state model clean.\n- Line objects support dash arrays for style variants (solid, dashed, dotted).\n- Canvas view should fill available width.

All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/S02-PLAN.md`\n- Task plan source: `.gsd/milestones/M002/slices/S02/tasks/T01-PLAN.md`\n- Prior task summaries in this slice:\n- (no prior tasks)\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T01-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T01-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T01 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M002/slices/S02/S02-PLAN.md`\n**Goal:** Build the Konva.js-powered 2D design canvas (View 2) with artboard shapes, basic shapes (rect/circle/ellipse/line), imported SVG rendering, selection handles, multi-select, object/layer panel with reorder, alignment tools, and undo/redo.\n**Demo:** After this: Create artboards in each shape, add/move/resize shapes, multi-select with alignment, undo/redo through history\n\n## UNIT: Execute Task T01 (\"Canvas types, state hook with undo/redo, artboard setup, and test infrastructure\") — Slice S02 (\"Design Canvas Core (View 2)\"), Milestone M002\n\n## Resume State\n- No continue file present.

This is the riskiest piece — the state model shape affects every downstream component.\n\nThe useCanvasState hook is a useReducer + useRef pattern: current state in a reducer (triggers re-renders), history stack in a useRef (avoids re-renders on history push). Every mutation dispatches through the reducer which also pushes a history snapshot.

Layout: top toolbar area, left canvas with KonvaStage, right panel area (wired in T03). Receives svgData and traceMetadata props from App.tsx.\n- Wire DesignCanvas into App.tsx replacing the placeholder div. Remove underscore prefixes from _svgResult and _traceMetadata variables.\n- KonvaStage renders: (1) artboard background shape using Konva.Rect/Path/Circle based on ArtboardConfig, (2) all canvas objects from useCanvasState mapped to Konva components, (3) Transformer attached to selected nodes, (4) rubber-band selection rectangle for multi-select.\n- Imported SVG from View 1: convert SVG string → Blob URL → Image element → Konva.Image. Auto-add to canvas objects on mount if svgData is provided.\n- Shape tools: rect, circle, ellipse, line creation. Click canvas in tool mode to place shape at click position with default dimensions. Tool state tracked in DesignCanvas.\n- Selection: click shape to select (single), shift-click to add to selection, click empty area to deselect, rubber-band rectangle selects all intersecting shapes.\n- Transformer: on onTransformEnd, reset scaleX/scaleY to 1 and multiply into width/height to keep state model clean.\n- Line objects support dash arrays for style variants (solid, dashed, dotted).\n- Canvas view should fill available width. Override #root width constraint for canvas view or make canvas flex within it.\n\nIMPORTANT tsconfig constraints: noUnusedLocals and noUnusedParameters are strict.

Ensure shortcuts only fire when canvas view is active and no text input is focused (check activeElement).\n\nFinal integration:\n- Verify the full flow: View 1 → Use This → Artboard Setup → Canvas with imported SVG\n- Verify undo/redo buttons in toolbar reflect stack state (disabled when empty)\n- Verify all panel components render and dispatch correctly\n- Run full test suite: all existing 23

Exposes 10 mutators: addObject, removeObject, updateObject, selectObjects, deselectAll, reorderObject, toggleVisibility, toggleLock, setArtboard, plus undo/redo. Selection actions intentionally excluded from undo stack. History capped at 50 snapshots.\n\n3. **Artboard shape utilities** (`artboardShapes.ts`): SVG path generators for shield and pennant shapes, dimension presets for all 7 artboard shapes, unit conversion functions (toPx/fromPx at 96 PPI), and artboardClipPath resolver.\n\n4. **Alignment utilities** (`alignment.ts`): 9 pure functions — alignLeft/Center/Right/Top/Middle/Bottom, distributeHorizontal/Vertical, centerOnArtboard. All accept BoundingRect arrays and return PositionUpdate arrays.\n\n5. **ArtboardSetup component**: Modal overlay with shape picker (7 shapes), width/height number inputs (square/circle enforce equal dimensions), inches/mm radio toggle, and Create button that produces a fully-formed ArtboardConfig.\n\n6. **Test infrastructure**: Installed konva, react-konva, vitest-canvas-mock. Extended test-setup.ts with `import 'vitest-canvas-mock'` so Konva components don't crash in jsdom. Initially tried jest-canvas-mock but it references Jest globals — switched to vitest-canvas-mock.\n\n## Verification\n\nRan the full verification command from the task plan:\n\n```\ncd app && npx vitest run --reporter=verbose && npx tsc --noEmit\n```\n\n- **71 tests pass** (23 pre-existing + 48 new): 19 useCanvasState tests, 14 alignment tests, 15 artboardShapes tests\n- **TypeScript compiles with zero errors** under strict mode (noUnusedLocals, noUnusedParameters)\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `cd app && npx vitest run --reporter=verbose` | 0 | ✅ pass | 2.09s |\n| 2 | `cd app && npx tsc --noEmit` | 0 | ✅ pass | 2.1s |\n\n## Diagnostics\n\nNo runtime observability surfaces — this task is pure types, hooks, utilities, and a UI component. Downstream tasks (T02–T04) will wire these into the live canvas view.\n\n## Deviations\n\n- Used `vitest-canvas-mock` instead of `jest-canvas-mock` as specified in the plan. The jest-canvas-mock package references `jest` globals (`jest.fn()` in `createImageBitmap.js`) which don't exist in Vitest, causing all test suites to fail with `ReferenceError: jest is not defined`. vitest-canvas-mock is a Vitest-compatible fork of the same library.\n\n## Known Issues\n\nNone.\n\n## Files Created/Modified\n\n- `app/src/types/canvas.ts` — Created: CanvasObject discriminated union, ArtboardConfig, CanvasState, ArtboardShape, LineStyle types\n- `app/src/hooks/useCanvasState.ts` — Created: Central state hook with useReducer + useRef undo/redo pattern\n- `app/src/hooks/__tests__/useCanvasState.test.ts` — Created: 19 tests covering all state transitions and undo/redo\n- `app/src/utils/artboardShapes.ts` — Created: Shape path generators, dimension presets, unit conversion\n- `app/src/utils/__tests__/artboardShapes.test.ts` — Created: 15 tests for paths, presets, and unit conversion\n- `app/src/utils/alignment.ts` — Created: 9 pure alignment/distribute/center functions\n- `app/src/utils/__tests__/alignment.test.ts` — Created: 14 tests for all alignment calculations\n- `app/src/components/canvas/ArtboardSetup.tsx` — Created: Artboard setup modal component\n- `app/src/test-setup.ts` — Modified: Added `import 'vitest-canvas-mock'`\n- `app/package.json` — Modified: Added konva, react-konva, vitest-canvas-mock dependencies\n","path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T01-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1812,"cacheRead":88440,"cacheWrite":616,"totalTokens":90869,"cost":{"input":0.000005,"output":0.0453,"cacheRead":0.044219999999999995,"cacheWrite":0.00385,"total":0.093375}},"stopReason":"toolUse","timestamp":1774503047763}} +{"type":"message","id":"e0382dd0","parentId":"d175c6f8","timestamp":"2026-03-26T05:31:25.719Z","message":{"role":"toolResult","toolCallId":"toolu_015RtNPqJPy9orLxMUAK5oXu","toolName":"write","content":[{"type":"text","text":"Successfully wrote 5829 bytes to /home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T01-SUMMARY.md"}],"isError":false,"timestamp":1774503085718}} +{"type":"message","id":"be31f3af","parentId":"e0382dd0","timestamp":"2026-03-26T05:31:28.869Z","message":{"role":"assistant","content":[{"type":"text","text":"Now record a knowledge entry about the vitest-canvas-mock finding, then complete the task."},{"type":"toolCall","id":"toolu_019X7mPqhPKraPdijC3Lx9Ka","name":"bash","arguments":{"command":"cat .gsd/KNOWLEDGE.md 2>/dev/null || echo \"FILE_NOT_FOUND\""}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":97,"cacheRead":89056,"cacheWrite":1875,"totalTokens":91029,"cost":{"input":0.000005,"output":0.002425,"cacheRead":0.044528,"cacheWrite":0.01171875,"total":0.05867675}},"stopReason":"toolUse","timestamp":1774503085718}} +{"type":"message","id":"09d9dc34","parentId":"be31f3af","timestamp":"2026-03-26T05:31:28.880Z","message":{"role":"toolResult","toolCallId":"toolu_019X7mPqhPKraPdijC3Lx9Ka","toolName":"bash","content":[{"type":"text","text":"# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit.

Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n| P003 | PostProcessResult is the universal intermediate representation | engine/pipeline/postprocess.py → engine/output/ | All output generators (DXF, JSON, SVG) consume PostProcessResult. Never generate output directly from raw SVG strings. |\n| P004 | _format_response() for consistent multi-format API responses | engine/api/routes.py | DXF returns binary Response with X-Kerf-Metadata header; SVG/JSON return JSON envelopes. Use _format_response() for both /engine/trace and /engine/simplify. |\n| P005 | Preset-driven pipeline: resolve_params() merges preset → user | engine/presets/loader.py, engine/api/routes.py | Presets define defaults for all pipeline stages. User params override. Mode comes from preset unless user explicitly sets it. |\n| P006 | JSON.stringify for React hook dependency stabilization | app/src/hooks/useDebouncedTrace.ts | Object params in useEffect deps cause infinite loops (new ref each render). Stringify the params object and use the string in the deps array. Avoids requiring callers to useMemo. |\n| P007 | Vite dev proxy for engine API calls | app/vite.config.ts | `/engine/*` requests proxy to `http://localhost:8000`. API client uses relative URLs (`/engine/presets`). No CORS issues in dev because same-origin via proxy. |\n| P008 | CSS modules for views, global App.css for shared component styles | app/src/views/*.module.css, app/src/App.css | View-specific layout in CSS modules avoids conflicts. Shared styles (upload zone, preset cards, buttons) in App.css for cross-component reuse. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them.

Fix these issues before completing the task.\n\n## Working Directory\n\nYour working directory is `/home/aux/development/xpltdco/kerf-engine`. All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/S02-PLAN.md`\n- Task plan source: `.gsd/milestones/M002/slices/S02/tasks/T02-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M002/slices/S02/tasks/T01-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T02-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T02-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T02 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M002/slices/S02/S02-PLAN.md`\n**Goal:** Build the Konva.js-powered 2D design canvas (View 2) with artboard shapes, basic shapes (rect/circle/ellipse/line), imported SVG rendering, selection handles, multi-select, object/layer panel with reorder, alignment tools, and undo/redo.\n**Demo:** After this: Create artboards in each shape, add/move/resize shapes, multi-select with alignment, undo/redo through history\n\n## Verification Failures\n\n### ❌ `npx vitest run --reporter=verbose` (exit code 1)\n```stderr\nnpm warn exec The following package was not found and will be installed: vitest@4.1.1\n\n\u001b[31m⎯⎯⎯⎯⎯⎯\u001b[39m\u001b[1m\u001b[41m Failed Tests 34 \u001b[49m\u001b[22m\u001b[31m⎯⎯⎯⎯⎯⎯⎯\u001b[39m\n\n\u001b[41m\u001b[1m FAIL \u001b[22m\u001b[49m app/src/components/__tests__/OutputInfoBar.test.tsx\u001b[2m > \u001b[22mOutputInfoBar\u001b[2m > \u001b[22mshows placeholder when metadata is null\n\u001b[31m\u001b[1mReferenceError\u001b[22m: document is not defined\u001b[39m\n\u001b[90m \u001b[2m❯\u001b[22m render app/node_modules/@testing-library/react/dist/pure.js:\u001b[2m256:5\u001b[22m\u001b[39m\n\u001b[36m \u001b[2m❯\u001b[22m app/src/components/__tests__/OutputInfoBar.test.tsx:\u001b[2m21:27\u001b[22m\u001b[39m\n \u001b[90m 19|\u001b[39m \u001b[34mdescribe\u001b[39m(\u001b[32m'OutputInfoBar'\u001b[39m\u001b[33m,\u001b[39m () \u001b[33m=>\u001b[39m {\n \u001b[90m 20|\u001b[39m \u001b[34mit\u001b[39m(\u001b[32m'shows placeholder when metadata is null'\u001b[39m\u001b[33m,\u001b[39m () \u001b[33m=>\u001b[39m {\n \u001b[90m 21|\u001b[39m \u001b[35mconst\u001b[39m { container } \u001b[33m=\u001b[39m \u001b[34mrender\u001b[39m(\u001b[33m<\u001b[39m\u001b[33mOutputInfoBar\u001b[39m \u001b[33mmetadata\u001b[39m\u001b[33m=\u001b[39m\u001b[33m{\u001b[39m\u001b[35mnull\u001b[39m\u001b[33m}\u001b[39m \u001b[33m/\u001b[39m\u001b[33m>\u001b[39m)\u001b[33m;\u001b[39m\n \u001b[90m |\u001b[39m \u001b[31m^\u001b[39m\n \u001b[90m 22|\u001b[39m expect(container.querySelector('.output-info-bar--empty')).toBeTru…\n \u001b[90m 23|\u001b[39m \u001b[34mexpect\u001b[39m(screen\u001b[33m.\u001b[39m\u001b[34mgetByText\u001b[39m(\u001b[36m/trace an image/i\u001b[39m))\u001b[33m.\u001b[39m\u001b[34mtoBeInTheDocument\u001b[39m()\u001b[33m;\u001b[39m\n\n\u001b[31m\u001b[2m⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯[1/34]⎯\u001b[22m\u001b[39m\n\n\u001b[41m\u001b[1m FAIL \u001b[22m\u001b[49m app/src/components/__tests__/OutputInfoBar.test.tsx\u001b[2m > \u001b[22mOutputInfoBar\u001b[2m > \u001b[22mrenders stats with green indicators for normal metadata\n\u001b[31m\u001b[1mReferenceError\u001b[22m: document is not defined\u001b[39m\n\u001b[90m \u001b[2m❯\u001b[22m render app/node_modules/@testing-library/react/dist/pure.js:\u001b[2m256:5\u001b[22m\u001b[39m\n\u001b[36m \u001b[2m❯\u001b[22m app/src/components/__tests__/OutputInfoBar.test.tsx:\u001b[2m28:5\u001b[22m\u001b[39m\n \u001b[90m 26|\u001b[39m \u001b[34mit\u001b[39m(\u001b[32m'renders stats with green indicators for normal metadata'\u001b[39m\u001b[33m,\u001b[39m () \u001b[33m=>\u001b[39m {\n \u001b[90m 27|\u001b[39m \u001b[35mconst\u001b[39m meta \u001b[33m=\u001b[39m \u001b[34mmakeMetadata\u001b[39m()\u001b[33m;\u001b[39m\n \u001b[90m 28|\u001b[39m \n…[truncated]\n```\n\n### ❌ `npx tsc --noEmit` (exit code 1)\n```stderr\nnpm warn exec The following package was not found and will be installed: tsc@2.0.4\n\n```\n\n---\n\nYou are executing GSD auto-mode.\n\n## UNIT: Execute Task T02 (\"Konva stage with artboard rendering, imported SVG, selection handles, and shape tools\") — Slice S02 (\"Design Canvas Core (View 2)\"), Milestone M002\n\n## Resume State\n- No continue file present.

This is the riskiest piece — the state model shape affects every downstream component.\n\nThe useCanvasState hook is a useReducer + useRef pattern: current state in a reducer (triggers re-renders), history stack in a useRef (avoids re-renders on history push). Every mutation dispatches through the reducer which also pushes a history snapshot. Undo/redo pops from history.\n\nThe ArtboardSetup component renders a modal overlay on first entering the canvas view with shape picker (rect, square, circle, oval, shield, pennant, custom), width/height number inputs, and inches/mm units toggle. On confirm, it produces an ArtboardConfig that initializes the canvas.\n\nInstall konva, react-konva, and jest-canvas-mock as dependencies.

KonvaStage renders the artboard background (Rect for rect/square, Circle for circle, Ellipse for oval, Path for shield/pennant/custom), maps all CanvasObject types to Konva primitives (Rect, Circle, Ellipse, Line with dash arrays, Image via KonvaImageWrapper), attaches a Transformer to selected nodes, and renders a rubber-band selection rectangle for multi-select. Shape creation tools (rect, circle, ellipse, line) place default-sized shapes at click position when in tool mode.\n\nDesignCanvas is the View 2 container with a three-zone layout: top toolbar (tool buttons + undo/redo), left canvas area (KonvaStage fills available space via ResizeObserver), and right panel placeholder (for T03). It manages tool state, the artboard setup flow (shows ArtboardSetup on first render, transitions to canvas on confirm), and imported SVG loading (converts SVG string → Blob URL → Image, auto-scales to fit artboard, auto-adds as ImageObject).\n\nUpdated App.tsx to render DesignCanvas with svgResult and traceMetadata props, removing underscore prefixes from state variables. Added canvas toolbar button styles and artboard setup modal styles to App.css.\n\n## Verification\n\nRan `cd app && npx tsc --noEmit` — zero type errors. Ran `cd app && npx vitest run --reporter=verbose` — all 71 tests pass (6 test files, 0 failures).\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `cd app && npx tsc --noEmit` | 0 | ✅ pass | 2300ms |\n| 2 | `cd app && npx vitest run --reporter=verbose` | 0 | ✅ pass | 2060ms |\n\n## Diagnostics\n\nNo runtime observability surfaces added — this is a UI rendering layer. Canvas state can be inspected via React DevTools (useCanvasState hook state). Konva stage is accessible via stageRef for debugging.\n\n## Deviations\n\nNone.\n\n## Known Issues\n\nNone.\n\n## Files Created/Modified\n\n- `app/src/components/canvas/KonvaStage.tsx` — New: Konva Stage+Layer with artboard rendering, shape objects, Transformer, rubber-band selection, shape creation tools\n- `app/src/views/DesignCanvas.tsx` — New: View 2 container with toolbar, tool state, artboard setup flow, SVG import, ResizeObserver\n- `app/src/views/DesignCanvas.module.css` — New: CSS module for canvas view three-zone layout\n- `app/src/App.tsx` — Updated: wired DesignCanvas with svgResult/traceMetadata props, removed underscore prefixes\n- `app/src/App.css` — Updated: added canvas toolbar button styles, artboard setup modal styles\n","path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T02-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1266,"cacheRead":93954,"cacheWrite":604,"totalTokens":95825,"cost":{"input":0.000005,"output":0.031650000000000005,"cacheRead":0.046977,"cacheWrite":0.003775,"total":0.08240700000000001}},"stopReason":"toolUse","timestamp":1774503331238}} +{"type":"message","id":"608c17af","parentId":"fd026a45","timestamp":"2026-03-26T05:36:00.064Z","message":{"role":"toolResult","toolCallId":"toolu_01XzBEr3bRXTpaNAePmcHEz1","toolName":"write","content":[{"type":"text","text":"Successfully wrote 4103 bytes to /home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T02-SUMMARY.md"}],"isError":false,"timestamp":1774503360061}} +{"type":"message","id":"c9b76f8b","parentId":"608c17af","timestamp":"2026-03-26T05:36:12.586Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_01R7m7pitjpDxi66SMbwHN1G","name":"gsd_complete_task","arguments":{"blockerDiscovered":false,"deviations":"None.","keyDecisions":["Artboard centered on stage via computed offsets; object positions stored relative to artboard origin","SVG import uses Blob URL → Image element → Konva.Image with auto-scale to fit artboard","Used :has() CSS selector on #app to override #root width constraint for canvas view"],"keyFiles":["app/src/components/canvas/KonvaStage.tsx","app/src/views/DesignCanvas.tsx","app/src/views/DesignCanvas.module.css","app/src/App.tsx","app/src/App.css"],"knownIssues":"None.","milestoneId":"M002","narrative":"Created KonvaStage component rendering artboard backgrounds (Rect/Circle/Ellipse/Path based on ArtboardConfig shape), all five CanvasObject types mapped to Konva primitives with drag/transform handlers, Transformer synced to selected nodes, and rubber-band selection rectangle.

Fix these issues before completing the task.\n\n## Working Directory\n\nYour working directory is `/home/aux/development/xpltdco/kerf-engine`. All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/S02-PLAN.md`\n- Task plan source: `.gsd/milestones/M002/slices/S02/tasks/T03-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M002/slices/S02/tasks/T01-SUMMARY.md`\n- `.gsd/milestones/M002/slices/S02/tasks/T02-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T03-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes.

ObjectPanel for layer management, the AlignmentBar for spatial arrangement, the CanvasToolbar for tool switching and canvas controls, and the ShapeProperties panel for editing selected objects.\n\nObjectPanel:\n- Lists canvas objects by z-order (top of list = frontmost layer)\n- Each row shows: drag handle, object type icon, name (double-click to rename), visibility toggle (eye icon), lock toggle (lock icon)\n- Click row to select object on canvas, shift-click for multi-select\n- Drag-to-reorder changes z-order in state (which changes render order in KonvaStage)\n- Wire to useCanvasState: reorderObject, toggleVisibility, toggleLock, selectObjects\n\nAlignmentBar:\n- Appears when 1+ objects selected\n- Buttons: align left, align center, align right, align top, align middle, align bottom\n- When 2+ selected: distribute horizontally, distribute vertically\n- Center on artboard button (works with 1+ selected)\n- Consumes alignment utility functions from utils/alignment.ts\n- Dispatches batch updateObject calls through useCanvasState\n\nCanvasToolbar:\n- Tool buttons: pointer/select (default), rectangle, circle, ellipse, line\n- Active tool highlighted with accent color\n- Undo/redo buttons (disabled when stack empty) — connected to useCanvasState undo/redo\n- Grid toggle button\n- Zoom controls (zoom in, zoom out, fit to artboard)\n\nShapeProperties:\n- Shown when exactly 1 shape selected\n- Fields: stroke color (color input), stroke weight (number input), fill color (color input with toggle), width/height display\n- For line objects: line style dropdown (solid, dashed, dotted)\n- Changes dispatch updateObject through useCanvasState\n\nWire all panels into DesignCanvas.tsx layout slots.\n\n## Inputs\n\n-

Each row has a drag handle, type icon, editable name (double-click to rename), visibility eye toggle, and lock toggle. Supports click-to-select with shift-click multi-select, and HTML5 drag-to-reorder that dispatches reorderObject through useCanvasState.\n\n**AlignmentBar** — Conditionally rendered when 1+ objects are selected. Provides 6 alignment buttons (left/center/right/top/middle/bottom), 2 distribute buttons (horizontal/vertical, shown only with 2+ selected), and center-on-artboard. Converts CanvasObject types to BoundingRect format and applies position updates through the alignment utility functions from T01.\n\n**CanvasToolbar** — Replaces the inline toolbar from T02 with a dedicated component. Includes tool switcher (pointer/rect/circle/ellipse/line), undo/redo with disabled states, grid toggle with active highlight, and zoom controls (in/out/fit with percentage display).\n\n**ShapeProperties** — Shown when exactly 1 object is selected. Displays dimensions (W/H, read-only), position (X/Y), stroke color (color picker), stroke weight (number input), fill color with toggle checkbox (shapes only), line style dropdown (lines only — solid/dashed/dotted), opacity slider, and rotation display.\n\nUpdated DesignCanvas.tsx to replace the inline toolbar and panel placeholder with the new components, adding zoom/grid state management and wiring all panel callbacks to useCanvasState actions. Added comprehensive CSS for all four components to App.css.\n\n## Verification\n\nRan `cd app && npx tsc --noEmit` — zero type errors. Ran `cd app && npx vitest run --reporter=verbose` — all 71 tests pass (6 test files, 0 failures).\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `cd app && npx tsc --noEmit` | 0 | ✅ pass | ~2000ms |\n| 2 | `cd app && npx vitest run --reporter=verbose` | 0 | ✅ pass | 2030ms |\n\n## Diagnostics\n\nAll four panel components expose data-testid attributes for automated testing: `object-panel`, `alignment-bar`, `canvas-toolbar`, `shape-properties`. Individual interactive elements also have testids (e.g., `tool-btn-pointer`, `undo-btn`, `zoom-level`, `stroke-color-input`).\n\n## Deviations\n\nNone.\n\n## Known Issues\n\nNone.\n\n## Files Created/Modified\n\n- `app/src/components/canvas/ObjectPanel.tsx` — New: layer list with reorder, visibility/lock toggles, rename, select\n- `app/src/components/canvas/AlignmentBar.tsx` — New: alignment and distribution buttons wired to alignment utils\n- `app/src/components/canvas/CanvasToolbar.tsx` — New: tool switcher, undo/redo, grid toggle, zoom controls\n- `app/src/components/canvas/ShapeProperties.tsx` — New: property editor for selected shape (stroke, fill, dimensions, line style, opacity)\n- `app/src/views/DesignCanvas.tsx` — Replaced inline toolbar and panel placeholder with all four panel components, added zoom/grid state\n- `app/src/App.css` — Added styles for canvas-toolbar, object-panel, alignment-bar, and shape-properties components\n","path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T03-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1358,"cacheRead":99765,"cacheWrite":611,"totalTokens":101735,"cost":{"input":0.000005,"output":0.03395,"cacheRead":0.049882499999999996,"cacheWrite":0.00381875,"total":0.08765624999999999}},"stopReason":"toolUse","timestamp":1774503571661}} +{"type":"message","id":"b447f1af","parentId":"76c75960","timestamp":"2026-03-26T05:40:00.411Z","message":{"role":"toolResult","toolCallId":"toolu_014BRHH4S6TZfYzKUeE6NDXE","toolName":"write","content":[{"type":"text","text":"Successfully wrote 4539 bytes to /home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T03-SUMMARY.md"}],"isError":false,"timestamp":1774503600409}} +{"type":"message","id":"6528ff0d","parentId":"b447f1af","timestamp":"2026-03-26T05:40:11.169Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_0191TqDXfc3o1W6JkK2tMTGc","name":"gsd_task_complete","arguments":{"blockerDiscovered":false,"deviations":"None.","keyDecisions":["Extracted inline toolbar from DesignCanvas into standalone CanvasToolbar component with zoom and grid state","ObjectPanel displays objects in reverse z-order (frontmost layer at top) matching standard design tool UX","ShapeProperties uses type narrowing via discriminated union to show type-specific fields"],"keyFiles":["app/src/components/canvas/ObjectPanel.tsx","app/src/components/canvas/AlignmentBar.tsx","app/src/components/canvas/CanvasToolbar.tsx","app/src/components/canvas/ShapeProperties.tsx","app/src/views/DesignCanvas.tsx","app/src/App.css"],"knownIssues":"None.","milestoneId":"M002","narrative":"Created four React components forming the complete panel system around the canvas.

Fix these issues before completing the task.\n\n## Working Directory\n\nYour working directory is `/home/aux/development/xpltdco/kerf-engine`. All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/S02-PLAN.md`\n- Task plan source: `.gsd/milestones/M002/slices/S02/tasks/T04-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M002/slices/S02/tasks/T01-SUMMARY.md`\n- `.gsd/milestones/M002/slices/S02/tasks/T02-SUMMARY.md`\n- `.gsd/milestones/M002/slices/S02/tasks/T03-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T04-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes.

This is the riskiest piece — the state model shape affects every downstream component.\n\nThe useCanvasState hook is a useReducer + useRef pattern: current state in a reducer (triggers re-renders), history stack in a useRef (avoids re-renders on history push). Every mutation dispatches through the reducer which also pushes a history snapshot. Undo/redo pops from history.\n\nThe ArtboardSetup component renders a modal overlay on first entering the canvas view with shape picker (rect, square, circle, oval, shield, pennant, custom), width/height number inputs, and inches/mm units toggle. On confirm, it produces an ArtboardConfig that initializes the canvas.\n\nInstall konva, react-konva, and jest-canvas-mock as dependencies.

Layout: top toolbar area, left canvas with KonvaStage, right panel area (wired in T03). Receives svgData and traceMetadata props from App.tsx.\n- Wire DesignCanvas into App.tsx replacing the placeholder div. Remove underscore prefixes from _svgResult and _traceMetadata variables.\n- KonvaStage renders: (1) artboard background shape using Konva.Rect/Path/Circle based on ArtboardConfig, (2) all canvas objects from useCanvasState mapped to Konva components, (3) Transformer attached to selected nodes, (4) rubber-band selection rectangle for multi-select.\n- Imported SVG from View 1: convert SVG string → Blob URL → Image element → Konva.Image. Auto-add to canvas objects on mount if svgData is provided.\n- Shape tools: rect, circle, ellipse, line creation. Click canvas in tool mode to place shape at click position with default dimensions. Tool state tracked in DesignCanvas.\n- Selection: click shape to select (single), shift-click to add to selection, click empty area to deselect, rubber-band rectangle selects all intersecting shapes.\n- Transformer: on onTransformEnd, reset scaleX/scaleY to 1 and multiply into width/height to keep state model clean.\n- Line objects support dash arrays for style variants (solid, dashed, dotted).\n- Canvas view should fill available width.

On investigation, both `npx tsc --noEmit` and `npx vitest run` passed cleanly, indicating the prior failures were transient (likely a stale environment or missing jsdom setup that was already fixed).\n\nThe actual task work was straightforward: added a `useEffect` with a `window.addEventListener('keydown', ...)` handler to `DesignCanvas.tsx` implementing all five keyboard shortcuts. The handler checks `document.activeElement?.tagName` to skip shortcuts when the user is typing in an input, textarea, or select element. The `removeObject` destructured binding was already available but aliased as `_removeObject` (unused) — unwrapped it for the Delete/Backspace handler.\n\n## Verification\n\n- `npx tsc --noEmit` — zero errors, clean compilation\n- `npx vitest run --reporter=verbose` — 71 tests pass across 6 test files (engine API, alignment, artboard shapes, useCanvasState, OutputInfoBar, useDebouncedTrace)\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `cd app && npx tsc --noEmit` | 0 | ✅ pass | 2.6s |\n| 2 | `cd app && npx vitest run --reporter=verbose` | 0 | ✅ pass | 2.1s |\n\n## Diagnostics\n\nNone — keyboard shortcuts are pure UI wiring with no backend or persistent state to inspect.\n\n## Deviations\n\nNone.\n\n## Known Issues\n\nNone.\n\n## Files Created/Modified\n\n- `app/src/views/DesignCanvas.tsx` — Added keyboard shortcut useEffect handler (Ctrl+Z, Ctrl+Shift+Z, Ctrl+Y, Delete, Backspace, Escape, Ctrl+A); unwrapped `_removeObject` alias to `removeObject` for use in Delete handler\n","path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T04-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":859,"cacheRead":74002,"cacheWrite":596,"totalTokens":75458,"cost":{"input":0.000005,"output":0.021475,"cacheRead":0.037001,"cacheWrite":0.003725,"total":0.062206000000000004}},"stopReason":"toolUse","timestamp":1774503668255}} +{"type":"message","id":"8dc348e1","parentId":"0d426f5f","timestamp":"2026-03-26T05:41:26.640Z","message":{"role":"toolResult","toolCallId":"toolu_011bkZyxu3TY8cjSLsBEniGP","toolName":"write","content":[{"type":"text","text":"Successfully wrote 2559 bytes to /home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/tasks/T04-SUMMARY.md"}],"isError":false,"timestamp":1774503686638}} +{"type":"message","id":"8bc01568","parentId":"8dc348e1","timestamp":"2026-03-26T05:41:35.154Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_01FjFmXDSAHWWcKZDSXxevrQ","name":"gsd_complete_task","arguments":{"blockerDiscovered":false,"deviations":"None.","keyDecisions":["Keyboard shortcuts use window-level keydown listener with activeElement tag guard to skip input/textarea/select","Ctrl+Shift+Z checked before Ctrl+Z to avoid false undo on redo shortcut"],"keyFiles":["app/src/views/DesignCanvas.tsx"],"knownIssues":"None.","milestoneId":"M002","narrative":"Added a useEffect with window-level keydown listener to DesignCanvas.tsx implementing five keyboard shortcuts: Ctrl+Z (undo), Ctrl+Shift+Z/Ctrl+Y (redo), Delete/Backspace (remove selected), Escape (deselect all), Ctrl+A (select all).

View 2 is a Konva.js-powered 2D design environment with artboard shapes, text objects, basic shapes, layers, alignment tools, and undo/redo.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Import & Convert UI (View 1) | medium — debounced preview updates, engine api integration from browser | — | ✅ | Upload a PNG, see live preview with preset selection and slider controls, click 'Use This' to advance to canvas |\n| S02 | Design Canvas Core (View 2) | medium — konva.js setup, selection handles, undo/redo state management | S01 | ⬜ | Create artboards in each shape, add/move/resize shapes, multi-select with alignment, undo/redo through history |\n| S03 | Text System + Font Loading | medium — opentype.js integration, font loading from volume, path extraction accuracy | S02 | ⬜ | Add text objects, select fonts from picker, change size/spacing, convert text to paths — paths match original glyphs |\n\n---\n\n### Slice Plan\nSource: `.gsd/milestones/M002/slices/S02/S02-PLAN.md`\n\n# S02: Design Canvas Core (View 2)\n\n**Goal:** Build the Konva.js-powered 2D design canvas (View 2) with artboard shapes, basic shapes (rect/circle/ellipse/line), imported SVG rendering, selection handles, multi-select, object/layer panel with reorder, alignment tools, and undo/redo.\n**Demo:** After this: Create artboards in each shape, add/move/resize shapes, multi-select with alignment, undo/redo through history\n\n## Tasks\n- [x] **T01: Built canvas type system, useCanvasState hook with undo/redo, artboard shapes, alignment utils, ArtboardSetup component, and 48 new tests passing** — Establish the foundation that every other task depends on: canvas type definitions (discriminated union for canvas objects, artboard config, canvas state), the central useCanvasState hook with full CRUD + selection + undo/redo, artboard shape utilities, the ArtboardSetup component, and canvas mock setup for Vitest. This is the riskiest piece — the state model shape affects every downstream component.\n\nThe useCanvasState hook is a useReducer + useRef pattern: current state in a reducer (triggers re-renders), history stack in a useRef (avoids re-renders on history push). Every mutation dispatches through the reducer which also pushes a history snapshot. Undo/redo pops from history.\n\nThe ArtboardSetup component renders a modal overlay on first entering the canvas view with shape picker (rect, square, circle, oval, shield, pennant, custom), width/height number inputs, and inches/mm units toggle. On confirm, it produces an ArtboardConfig that initializes the canvas.\n\nInstall konva, react-konva, and jest-canvas-mock as dependencies. Set up canvas mock in test-setup.ts so Konva components don't crash in jsdom.\n - Estimate: 2h\n - Files: app/src/types/canvas.ts, app/src/hooks/useCanvasState.ts, app/src/hooks/__tests__/useCanvasState.test.ts, app/src/utils/artboardShapes.ts, app/src/utils/__tests__/artboardShapes.test.ts, app/src/utils/alignment.ts, app/src/utils/__tests__/alignment.test.ts, app/src/components/canvas/ArtboardSetup.tsx, app/src/test-setup.ts, app/package.json\n - Verify: cd app && npx vitest run --reporter=verbose && npx tsc --noEmit\n- [x] **T02: Built KonvaStage with artboard rendering, shape tools, selection handles, rubber-band multi-select, SVG import, and DesignCanvas view container** — Build the core Konva canvas rendering layer and wire it into the app. This task creates the KonvaStage component (Konva Stage + Layer with artboard background, all canvas objects, Transformer for selection handles, rubber-band selection rectangle), the DesignCanvas view container, and shape creation tools.\n\nKey implementation details:\n- DesignCanvas is the View 2 container. Layout: top toolbar area, left canvas with KonvaStage, right panel area (wired in T03). Receives svgData and traceMetadata props from App.tsx.\n- Wire DesignCanvas into App.tsx replacing the placeholder div. Remove underscore prefixes from _svgResult and _traceMetadata variables.\n- KonvaStage renders: (1) artboard background shape using Konva.Rect/Path/Circle based on ArtboardConfig, (2) all canvas objects from useCanvasState mapped to Konva components, (3) Transformer attached to selected nodes, (4) rubber-band selection rectangle for multi-select.\n- Imported SVG from View 1: convert SVG string → Blob URL → Image element → Konva.Image. Auto-add to canvas objects on mount if svgData is provided.\n- Shape tools: rect, circle, ellipse, line creation. Click canvas in tool mode to place shape at click position with default dimensions. Tool state tracked in DesignCanvas.\n- Selection: click shape to select (single), shift-click to add to selection, click empty area to deselect, rubber-band rectangle selects all intersecting shapes.\n- Transformer: on onTransformEnd, reset scaleX/scaleY to 1 and multiply into width/height to keep state model clean.\n- Line objects support dash arrays for style variants (solid, dashed, dotted).\n- Canvas view should fill available width. Override #root width constraint for canvas view or make canvas flex within it.\n\nIMPORTANT tsconfig constraints: noUnusedLocals and noUnusedParameters are strict. All variables must be used or prefixed with underscore.\n - Estimate: 2h30m\n - Files: app/src/views/DesignCanvas.tsx, app/src/views/DesignCanvas.module.css, app/src/components/canvas/KonvaStage.tsx, app/src/App.tsx, app/src/App.css\n - Verify: cd app && npx tsc --noEmit && npx vitest run --reporter=verbose\n- [x] **T03: Built four canvas UI panels (ObjectPanel, AlignmentBar, CanvasToolbar, ShapeProperties) with full state wiring into DesignCanvas view** — Build the UI panels that surround the canvas: the right-side ObjectPanel for layer management, the AlignmentBar for spatial arrangement, the CanvasToolbar for tool switching and canvas controls, and the ShapeProperties panel for editing selected objects.\n\nObjectPanel:\n- Lists canvas objects by z-order (top of list = frontmost layer)\n- Each row shows: drag handle, object type icon, name (double-click to rename), visibility toggle (eye icon), lock toggle (lock icon)\n- Click row to select object on canvas, shift-click for multi-select\n- Drag-to-reorder changes z-order in state (which changes render order in KonvaStage)\n- Wire to useCanvasState: reorderObject, toggleVisibility, toggleLock, selectObjects\n\nAlignmentBar:\n- Appears when 1+ objects selected\n- Buttons: align left, align center, align right, align top, align middle, align bottom\n- When 2+ selected: distribute horizontally, distribute vertically\n- Center on artboard button (works with 1+ selected)\n- Consumes alignment utility functions from utils/alignment.ts\n- Dispatches batch updateObject calls through useCanvasState\n\nCanvasToolbar:\n- Tool buttons: pointer/select (default), rectangle, circle, ellipse, line\n- Active tool highlighted with accent color\n- Undo/redo buttons (disabled when stack empty) — connected to useCanvasState undo/redo\n- Grid toggle button\n- Zoom controls (zoom in, zoom out, fit to artboard)\n\nShapeProperties:\n- Shown when exactly 1 shape selected\n- Fields: stroke color (color input), stroke weight (number input), fill color (color input with toggle), width/height display\n- For line objects: line style dropdown (solid, dashed, dotted)\n- Changes dispatch updateObject through useCanvasState\n\nWire all panels into DesignCanvas.tsx layout slots.\n - Estimate: 2h\n - Files: app/src/components/canvas/ObjectPanel.tsx, app/src/components/canvas/AlignmentBar.tsx, app/src/components/canvas/CanvasToolbar.tsx, app/src/components/canvas/ShapeProperties.tsx, app/src/views/DesignCanvas.tsx, app/src/views/DesignCanvas.module.css, app/src/App.css\n - Verify: cd app && npx tsc --noEmit && npx vitest run --reporter=verbose\n- [x] **T04: Add canvas keyboard shortcuts (undo/redo/delete/select-all/deselect) and verify full integration — 71 tests pass, zero TypeScript errors** — Wire keyboard shortcuts for the canvas, perform final integration checks, and ensure all tests pass.\n\nKeyboard shortcuts:\n- Ctrl+Z: undo (calls useCanvasState.undo)\n- Ctrl+Shift+Z (or Ctrl+Y): redo (calls useCanvasState.redo)\n- Delete/Backspace: remove selected objects (calls useCanvasState.removeObject for each selected ID)\n- Escape: deselect all (calls useCanvasState.deselectAll)\n- Ctrl+A: select all objects\n\nImplement via useEffect with keydown listener on the DesignCanvas container div (or window). Ensure shortcuts only fire when canvas view is active and no text input is focused (check activeElement).\n\nFinal integration:\n- Verify the full flow: View 1 → Use This → Artboard Setup → Canvas with imported SVG\n- Verify undo/redo buttons in toolbar reflect stack state (disabled when empty)\n- Verify all panel components render and dispatch correctly\n- Run full test suite: all existing 23 tests + all new tests must pass\n- Run TypeScript compiler: zero errors\n- Ensure no unused imports/variables (strict tsconfig)\n\nThis task closes the slice by ensuring everything works together as an integrated whole.\n - Estimate: 1h\n - Files: app/src/views/DesignCanvas.tsx, app/src/App.css\n - Verify: cd app && npx vitest run --reporter=verbose && npx tsc --noEmit\n\n---\n\n### Project Knowledge\nSource: `.gsd/KNOWLEDGE.md`\n\n# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit. Add entries when you discover something worth remembering.\n\n## Rules\n\n| # | Scope | Rule | Why | Added |\n|---|-------|------|-----|-------|\n\n## Patterns\n\n| # | Pattern | Where | Notes |\n|---|---------|-------|-------|\n| P001 | Test images generated programmatically via numpy | engine/tests/ | No fixture image files checked in. Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n| P003 | PostProcessResult is the universal intermediate representation | engine/pipeline/postprocess.py → engine/output/ | All output generators (DXF, JSON, SVG) consume PostProcessResult. Never generate output directly from raw SVG strings. |\n| P004 | _format_response() for consistent multi-format API responses | engine/api/routes.py | DXF returns binary Response with X-Kerf-Metadata header; SVG/JSON return JSON envelopes. Use _format_response() for both /engine/trace and /engine/simplify. |\n| P005 | Preset-driven pipeline: resolve_params() merges preset → user | engine/presets/loader.py, engine/api/routes.py | Presets define defaults for all pipeline stages. User params override. Mode comes from preset unless user explicitly sets it. |\n| P006 | JSON.stringify for React hook dependency stabilization | app/src/hooks/useDebouncedTrace.ts | Object params in useEffect deps cause infinite loops (new ref each render). Stringify the params object and use the string in the deps array. Avoids requiring callers to useMemo. |\n| P007 | Vite dev proxy for engine API calls | app/vite.config.ts | `/engine/*` requests proxy to `http://localhost:8000`. API client uses relative URLs (`/engine/presets`). No CORS issues in dev because same-origin via proxy. |\n| P008 | CSS modules for views, global App.css for shared component styles | app/src/views/*.module.css, app/src/App.css | View-specific layout in CSS modules avoids conflicts. Shared styles (upload zone, preset cards, buttons) in App.css for cross-component reuse. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them. Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003). All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n| L007 | Docker build context must be project root, not engine/ | Dockerfile.engine uses `COPY engine/...` paths relative to project root | Always build with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` from project root | Docker |\n| L008 | Engine container has dual health endpoints | /health on root (main.py) and /engine/health on router (routes.py) both exist | Use /engine/health for Docker HEALTHCHECK and external probes for namespace consistency | engine API, Docker |\n| L009 | useCallback-based triggerTrace caused infinite re-render loops | Object params create new references each render, retriggering useEffect even when values are unchanged | Restructure hook to use single useEffect with JSON.stringify(params) in dependency array instead of useCallback-based approach | app hooks, React |\n| L010 | jest-canvas-mock crashes in Vitest with \"ReferenceError: jest is not defined\" | jest-canvas-mock internally calls jest.fn() in createImageBitmap.js — Jest globals don't exist in Vitest | Use vitest-canvas-mock (a Vitest-compatible fork) instead. Import it in test-setup.ts. | app tests, canvas |\n\n---\n\n### Task Summary: T01\nSource: `.gsd/milestones/M002/slices/S02/tasks/T01-SUMMARY.md`\n\n---\nid: T01\nparent: S02\nmilestone: M002\nprovides: []\nrequires: []\naffects: []\nkey_files: [\"app/src/types/canvas.ts\", \"app/src/hooks/useCanvasState.ts\", \"app/src/hooks/__tests__/useCanvasState.test.ts\", \"app/src/utils/artboardShapes.ts\", \"app/src/utils/__tests__/artboardShapes.test.ts\", \"app/src/utils/alignment.ts\", \"app/src/utils/__tests__/alignment.test.ts\", \"app/src/components/canvas/ArtboardSetup.tsx\", \"app/src/test-setup.ts\", \"app/package.json\"]\nkey_decisions: [\"Used vitest-canvas-mock instead of jest-canvas-mock (jest globals unavailable in Vitest)\", \"select/deselect actions excluded from undo stack — selection is UI concern not content mutation\", \"History capped at 50 entries to bound memory\", \"useReducer + useRef pattern: reducer for renders, ref for undo/redo stacks\"]\npatterns_established: []\ndrill_down_paths: []\nobservability_surfaces: []\nduration: \"\"\nverification_result: \"Ran `cd app && npx vitest run --reporter=verbose` — 71 tests pass (6 test files, 0 failures).

A complex slice with 5 tasks across multiple subsystems needs thorough verification and a detailed summary. Scale the work below accordingly.\n\nThen:\n1. Use the **Slice Summary** and **UAT** output templates from the inlined context above\n2. If a `GSD Skill Preferences` block is present in system context, use it and the `` catalog in your system prompt to decide which skills to load and follow for this unit, without relaxing required verification or artifact rules.\n3. Run all slice-level verification checks defined in the slice plan. All must pass before marking the slice done. If any fail, fix them first.\n4. If the slice plan includes observability/diagnostic surfaces, confirm they work. Skip this for simple slices that don't have observability sections.\n5. If this slice produced evidence that a requirement changed status (Active → Validated, Active → Deferred, etc.), call `gsd_save_decision` with scope=\"requirement\", decision=\"{requirement-id}\", choice=\"{new-status}\", rationale=\"{evidence}\". Do NOT write `.gsd/REQUIREMENTS.md` directly — the engine renders it from the database.\n6. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/S02-SUMMARY.md` (compress all task summaries).\n7. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/S02-UAT.md` — a concrete UAT script with real test cases derived from the slice plan and task summaries. Include preconditions, numbered steps with expected outcomes, and edge cases. This must NOT be a placeholder or generic template — tailor every test case to what this slice actually built.\n8. Review task summaries for `key_decisions`. Append any significant decisions to `.gsd/DECISIONS.md` if missing.\n9. Review task summaries for patterns, gotchas, or non-obvious lessons learned. If any would save future agents from repeating investigation or hitting the same issues, append them to `.gsd/KNOWLEDGE.md`. Only add entries that are genuinely useful — don't pad with obvious observations.\n10. Call `gsd_complete_slice` with milestone_id, slice_id, the slice summary, and the UAT result. Do NOT manually mark the roadmap checkbox — the tool writes to the DB and renders the ROADMAP.md projection automatically.\n11. Do not run git commands — the system commits your changes and handles any merge after this unit succeeds.\n12. Update `.gsd/PROJECT.md` if it exists — refresh current state if needed.\n\n**You MUST call `gsd_complete_slice` with the slice summary and UAT content before finishing. The tool persists to both DB and disk and renders `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/S02-SUMMARY.md` and `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S02/S02-UAT.md` automatically.**\n\nWhen done, say: \"Slice S02

Built the central `useCanvasState` hook using a useReducer + useRef pattern — reducer drives re-renders for current state, ref holds undo/redo history stacks without triggering renders. Select/deselect are excluded from the undo stack (UI-only concern). History is capped at 50 entries. Created artboard shape utilities (shield/pennant SVG paths, dimension presets, unit conversion), 9 pure alignment/distribute functions, and the `ArtboardSetup` modal component. Installed konva, react-konva, and vitest-canvas-mock. 48 new tests passing.\n\n**T02 — Rendering Layer:** Created `KonvaStage` rendering artboard backgrounds (Rect/Circle/Ellipse/Path based on shape config), mapping all canvas objects to Konva primitives with drag/transform handlers, Transformer synced to selected nodes, and rubber-band multi-select rectangle. Built `DesignCanvas` view container with ResizeObserver-driven sizing, artboard setup flow, and SVG import (Blob URL → Image element → Konva.Image with auto-scale). Wired into `App.tsx` to receive real svgData/traceMetadata props from View 1.\n\n**T03 — Panel System:** Built four panel components: `ObjectPanel` (layer list in reverse z-order with drag reorder, visibility/lock toggles, rename), `AlignmentBar` (6 alignment + 2 distribute + center-on-artboard), `CanvasToolbar` (tool switcher, undo/redo, grid toggle, zoom controls), and `ShapeProperties` (stroke/fill/dimensions/line-style editing with discriminated union narrowing). All wired to useCanvasState in DesignCanvas.\n\n**T04 — Shortcuts & Integration:** Added window-level keyboard shortcuts (Ctrl+Z undo, Ctrl+Shift+Z redo, Delete/Backspace remove, Escape deselect, Ctrl+A select all) with activeElement guard to skip input fields. Verified full integration: View 1 → Use This → Artboard Setup → Canvas with imported SVG.

Upload a raster image in View 1\n2. Wait for trace preview to render\n3. Click \"Use This\" button\n4. **Expected:** Artboard Setup modal appears with shape picker, dimension inputs, and unit toggle\n\n### Test 2: Artboard Setup — Shape Selection\n1. In Artboard Setup modal, click each shape option: rect, square, circle, oval, shield, pennant\n2. **Expected:** Shape preview updates for each selection. Square and circle auto-set equal width/height. Width/height inputs update with preset dimensions.\n3. Toggle units between inches and mm\n4. **Expected:** Dimension values convert correctly (e.g., 3in → 76.2mm)\n5. Click \"Create Artboard\"\n6. **Expected:** Modal closes, Konva canvas renders with artboard background matching chosen shape\n\n### Test 3: Shape Creation Tools\n1. Click Rectangle tool in toolbar\n2. Click on the canvas\n3. **Expected:** A rectangle appears at the click position with default dimensions, black stroke, no fill\n4. Repeat with Circle tool and Ellipse tool\n5. **Expected:** Each shape appears correctly with default styling\n6. Click Line tool and click on canvas\n7. **Expected:** A horizontal line appears at the click position\n\n### Test 4: Object Selection & Transform\n1. Click on a shape on the canvas\n2. **Expected:** Selection handles (Transformer) appear around the shape. ObjectPanel highlights the selected row.\n3. Drag the shape to a new position\n4. **Expected:** Shape moves with cursor. Position updates in state.\n5. Drag a transform handle to resize\n6. **Expected:** Shape resizes. Width/height update (scaleX/scaleY reset to 1, dimensions multiplied).\n7. Click empty canvas area\n8. **Expected:** Shape deselected. Transformer hidden. ObjectPanel row unhighlighted.\n\n### Test 5: Multi-Select with Rubber Band\n1. Create 3+ shapes on canvas\n2. Click and drag on empty canvas area to draw a rubber-band rectangle over multiple shapes\n3. **Expected:** All shapes intersecting the rectangle are selected. Transformer wraps all selected nodes. Multiple rows highlighted in ObjectPanel.\n4. Shift-click an unselected shape\n5. **Expected:** Shape added to selection without deselecting others.\n\n### Test 6: ObjectPanel — Layer Management\n1. Create 3 shapes (they appear as layers in ObjectPanel in reverse z-order — newest on top)\n2. **Expected:** ObjectPanel lists all 3 shapes with type icons and default names\n3. Double-click a shape name in ObjectPanel\n4. **Expected:** Name becomes editable. Type new name, press Enter — name persists.\n5. Click the eye icon on a shape row\n6. **Expected:** Shape becomes invisible on canvas. Eye icon toggles to \"hidden\" state.\n7. Click the lock icon on a shape row\n8. **Expected:** Shape can no longer be dragged or resized on canvas.\n\n### Test 7: Alignment Tools\n1. Select 2+ shapes\n2. Click \"Align Left\" in AlignmentBar\n3. **Expected:** All selected shapes move so their left edges align with the leftmost shape's left edge\n4. Click \"Distribute Horizontally\" (requires 3+ shapes selected)\n5. **Expected:** Shapes evenly space horizontally\n6. Select 1 shape, click \"Center on Artboard\"\n7. **Expected:** Shape centers within the artboard bounds\n\n### Test 8: Shape Properties Panel\n1. Select a single rectangle\n2. **Expected:** ShapeProperties panel appears showing stroke color, stroke weight, fill color, width, height, opacity\n3.

Select a line object\n8. **Expected:** ShapeProperties shows line style dropdown (solid, dashed, dotted). Changing style updates the line's dash array.\n\n### Test 9: Undo/Redo\n1. Create a shape, move it, change its color (3 mutations)\n2. Press Ctrl+Z three times\n3. **Expected:** Each undo reverses one mutation in order: color reverts → position reverts → shape removed\n4. Press Ctrl+Shift+Z (or Ctrl+Y) twice\n5. **Expected:** Shape reappears, position restored\n6. Click undo/redo buttons in CanvasToolbar\n7. **Expected:** Same behavior as keyboard shortcuts. Buttons disabled when respective stack is empty.\n\n### Test 10: Keyboard Shortcuts\n1. Select a shape, press Delete (or Backspace)\n2. **Expected:** Shape removed from canvas and ObjectPanel\n3. Create multiple shapes, press Ctrl+A\n4. **Expected:** All shapes selected\n5. Press Escape\n6. **Expected:** All shapes deselected\n7. Focus a text input (e.g., shape name rename in ObjectPanel), press Delete\n8. **Expected:** Shortcut does NOT fire — normal text editing behavior occurs\n\n### Test 11: SVG Import from View 1\n1. Upload an image in View 1, complete tracing, click \"Use This\"\n2. Set up artboard, confirm\n3. **Expected:** Traced SVG appears as an image object on the canvas, auto-scaled to fit within artboard bounds. Object appears in ObjectPanel as an image type.\n\n### Test 12: Canvas Zoom & Grid\n1. Click zoom-in button in CanvasToolbar\n2. **Expected:** Canvas content appears larger\n3. Click zoom-out button\n4. **Expected:** Canvas content appears smaller\n5. Click \"Fit\" button\n6. **Expected:** Artboard fits within visible canvas area\n7. Toggle grid button\n8. **Expected:** Grid overlay toggles on/off on canvas\n\n### Edge Cases\n- **Empty undo:** Pressing Ctrl+Z with no history should do nothing (no crash)\n- **Delete with nothing selected:** Pressing Delete with no selection should do nothing\n- **Rapid undo/redo:** Rapidly alternating Ctrl+Z and Ctrl+Shift+Z should not corrupt state\n- **Window resize:** Canvas should resize responsively via ResizeObserver without layout breaks","verification":"Ran `cd app && npx vitest run --reporter=verbose` — 71 tests pass across 6 test files, 0 failures (exit 0).

Clean input/output contracts enable this. | No | human |\n| D002 | | architecture | Build order and gating strategy | Build Engine first (M001), then App canvas (M002), then Export+Deploy+Embed (M003). Human checkpoints gate each transition. | Brief explicitly mandates: validate engine output quality before building canvas UI, validate canvas before export/deploy. Engine is the hardest and most valuable piece. | No | human |\n| D003 | | engine | Post-processing replaces regex metadata extraction | postprocess_svg() pipeline replaces old _extract_svg_metadata() regex approach; all SVG paths are parsed into structured PathInfo objects with coordinates, area, island status | Structured path data is needed for DXF/JSON output generation, RDP simplification, and island detection. XML parsing is now necessary since we need actual coordinate data, not just counts. This supersedes D003's regex approach. | No | agent |\n| D004 | | architecture | Engine Docker image build strategy | Multi-stage build: builder stage compiles pypotrace with build-essential/libagg-dev/libpotrace-dev, runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl). Only engine source is copied — no App code. | Multi-stage keeps the runtime image small by excluding build tools. Copying only engine source enforces the Engine/App separation (D001). curl is included for Docker HEALTHCHECK. | Yes | agent |\n| D005 | | architecture | Frontend technology stack for Kerf App | Vite + React + TypeScript with plain CSS modules, Vitest for testing, raw fetch + FormData for engine API calls, no UI framework for V1 | Minimal dependency surface for a tool that needs fast iteration. The engine API uses multipart/form-data which works naturally with native fetch + FormData. CSS modules avoid global style conflicts without adding a framework. Vitest integrates natively with Vite's transform pipeline. No UI library needed — the app has a focused interface with ~8 components. | Yes | agent |\n| D006 | | frontend | React hook params stabilization strategy for useDebouncedTrace | JSON.stringify params in useEffect deps array, single-effect architecture | useCallback-based triggerTrace with object params caused infinite re-render loops because React creates new object references each render. JSON.stringify converts params to a stable string for dependency comparison, eliminating the need for callers to useMemo their params objects. Simpler API surface and no re-render bugs. | Yes | agent |\n| D007 | | architecture | Canvas object type system design | Discriminated union on `type` field: 'rect' \\| 'circle' \\| 'ellipse' \\| 'line' \\| 'image'. All objects share BaseCanvasObject (id, name, x, y, visible, locked, stroke, fill, opacity). Type-specific fields via intersection types. | TypeScript discriminated unions enable exhaustive type narrowing in switch/if statements, catching missing cases at compile time. Shared base keeps CRUD operations generic while type-specific panels (ShapeProperties) safely narrow to access unique fields. 'text' type will be added in S03. | Yes | agent |\n\n---\n\n### Project Knowledge\nSource: `.gsd/KNOWLEDGE.md`\n\n# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit. Add entries when you discover something worth remembering.\n\n## Rules\n\n| # | Scope | Rule | Why | Added |\n|---|-------|------|-----|-------|\n\n## Patterns\n\n| # | Pattern | Where | Notes |\n|---|---------|-------|-------|\n| P001 | Test images generated programmatically via numpy | engine/tests/ | No fixture image files checked in. Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n| P003 | PostProcessResult is the universal intermediate representation | engine/pipeline/postprocess.py → engine/output/ | All output generators (DXF, JSON, SVG) consume PostProcessResult. Never generate output directly from raw SVG strings. |\n| P004 | _format_response() for consistent multi-format API responses | engine/api/routes.py | DXF returns binary Response with X-Kerf-Metadata header; SVG/JSON return JSON envelopes. Use _format_response() for both /engine/trace and /engine/simplify. |\n| P005 | Preset-driven pipeline: resolve_params() merges preset → user | engine/presets/loader.py, engine/api/routes.py | Presets define defaults for all pipeline stages. User params override. Mode comes from preset unless user explicitly sets it. |\n| P006 | JSON.stringify for React hook dependency stabilization | app/src/hooks/useDebouncedTrace.ts | Object params in useEffect deps cause infinite loops (new ref each render). Stringify the params object and use the string in the deps array. Avoids requiring callers to useMemo. |\n| P007 | Vite dev proxy for engine API calls | app/vite.config.ts | `/engine/*` requests proxy to `http://localhost:8000`. API client uses relative URLs (`/engine/presets`). No CORS issues in dev because same-origin via proxy. |\n| P008 | CSS modules for views, global App.css for shared component styles | app/src/views/*.module.css, app/src/App.css | View-specific layout in CSS modules avoids conflicts. Shared styles (upload zone, preset cards, buttons) in App.css for cross-component reuse. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them. Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003). All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n| L007 | Docker build context must be project root, not engine/ | Dockerfile.engine uses `COPY engine/...` paths relative to project root | Always build with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` from project root | Docker |\n| L008 | Engine container has dual health endpoints | /health on root (main.py) and /engine/health on router (routes.py) both exist | Use /engine/health for Docker HEALTHCHECK and external probes for namespace consistency | engine API, Docker |\n| L009 | useCallback-based triggerTrace caused infinite re-render loops | Object params create new references each render, retriggering useEffect even when values are unchanged | Restructure hook to use single useEffect with JSON.stringify(params) in dependency array instead of useCallback-based approach | app hooks, React |\n| L010 | jest-canvas-mock crashes in Vitest with \"ReferenceError: jest is not defined\" | jest-canvas-mock internally calls jest.fn() in createImageBitmap.js — Jest globals don't exist in Vitest | Use vitest-canvas-mock (a Vitest-compatible fork) instead.

Built the central `useCanvasState` hook using a useReducer + useRef pattern — reducer drives re-renders for current state, ref holds undo/redo history stacks without triggering renders. Select/deselect are excluded from the undo stack (UI-only concern). History is capped at 50 entries. Created artboard shape utilities (shield/pennant SVG paths, dimension presets, unit conversion), 9 pure alignment/distribute functions, and the `ArtboardSetup` modal component. Installed konva, react-konva, and vitest-canvas-mock. 48 new tests passing.\n\n**T02 — Rendering Layer:** Created `KonvaStage` rendering artboard backgrounds (Rect/Circle/Ellipse/Path based on shape config), mapping all canvas objects to Konva primitives with drag/transform handlers, Transformer synced to selected nodes, and rubber-band multi-select rectangle. Built `DesignCanvas` view container with ResizeObserver-driven sizing, artboard setup flow, and SVG import (Blob URL → Image element → Konva.Image with auto-scale). Wired into `App.tsx` to receive real svgData/traceMetadata props from View 1.\n\n**T03 — Panel System:** Built four panel components: `ObjectPanel` (layer list in reverse z-order with drag reorder, visibility/lock toggles, rename), `AlignmentBar` (6 alignment + 2 distribute + center-on-artboard), `CanvasToolbar` (tool switcher, undo/redo, grid toggle, zoom controls), and `ShapeProperties` (stroke/fill/dimensions/line-style editing with discriminated union narrowing). All wired to useCanvasState in DesignCanvas.\n\n**T04 — Shortcuts & Integration:** Added window-level keyboard shortcuts (Ctrl+Z undo, Ctrl+Shift+Z redo, Delete/Backspace remove, Escape deselect, Ctrl+A select all) with activeElement guard to skip input fields. Verified full integration: View 1 → Use This → Artboard Setup → Canvas with imported SVG. All 71 tests pass, zero TypeScript errors.\n\n## Verification\n\nRan `cd app && npx vitest run --reporter=verbose` — 71 tests pass across 6 test files, 0 failures (exit 0). Ran `cd app && npx tsc --noEmit` — zero type errors under strict mode with noUnusedLocals/noUnusedParameters (exit 0).\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nUsed vitest-canvas-mock instead of jest-canvas-mock (plan specified jest-canvas-mock but it crashes in Vitest because it internally calls jest.fn()). This was identified in T01 and recorded as L010 in KNOWLEDGE.md.\n\n## Known Limitations\n\nCanvas components (KonvaStage, DesignCanvas panels) do not have dedicated unit tests — they were verified via TypeScript compilation and manual integration. Konva rendering in jsdom is limited since canvas operations are mocked. Drag-to-reorder in ObjectPanel uses simple index swapping, not full drag-and-drop library.\n\n## Follow-ups\n\nS03 will add 'text' type to the CanvasObject discriminated union and integrate opentype.js for font loading and text-to-path conversion. ShapeProperties panel will need a text-specific section. The canvas object type system (D008) was designed to accommodate this extension.\n\n## Files Created/Modified\n\n- `app/src/types/canvas.ts` — New — discriminated union type system for canvas objects (rect, circle, ellipse, line, image), ArtboardConfig, CanvasState, and CanvasAction types\n- `app/src/hooks/useCanvasState.ts` — New — central state management hook with useReducer+useRef for CRUD, selection, undo/redo, reorder, visibility/lock\n- `app/src/hooks/__tests__/useCanvasState.test.ts` — New — 20 tests covering all useCanvasState operations including undo/redo edge cases\n- `app/src/utils/artboardShapes.ts` — New — artboard shape presets, shield/pennant SVG path generators, toPx/fromPx unit conversion, artboardClipPath\n- `app/src/utils/__tests__/artboardShapes.test.ts` — New — 15 tests for artboard presets, path generation, unit conversion, clip paths\n- `app/src/utils/alignment.ts` — New — 9 pure alignment/distribute/center functions for canvas objects\n- `app/src/utils/__tests__/alignment.test.ts` — New — 13 tests for alignment, distribution, and center-on-artboard\n- `app/src/components/canvas/ArtboardSetup.tsx` — New — modal for artboard shape/size/unit selection on entering canvas view\n- `app/src/components/canvas/KonvaStage.tsx` — New — Konva Stage+Layer rendering artboard, all object types, Transformer, rubber-band selection\n- `app/src/components/canvas/ObjectPanel.tsx` — New — layer management panel with z-order list, reorder, visibility/lock toggles, rename\n- `app/src/components/canvas/AlignmentBar.tsx` — New — alignment and distribution toolbar consuming alignment utils\n- `app/src/components/canvas/CanvasToolbar.tsx` — New — tool switcher, undo/redo, grid toggle, zoom controls\n- `app/src/components/canvas/ShapeProperties.tsx` — New — property editor for selected shape (stroke, fill, dimensions, line style, opacity)\n- `app/src/views/DesignCanvas.tsx` — New — View 2 container wiring KonvaStage + all panels to useCanvasState, SVG import, keyboard shortcuts\n- `app/src/views/DesignCanvas.module.css` — New — CSS module for DesignCanvas layout\n- `app/src/App.tsx` — Modified — wired DesignCanvas with svgData/traceMetadata props, removed underscore prefixes\n- `app/src/App.css` — Modified — added comprehensive canvas UI styles (toolbar, panels, artboard setup, shape properties, alignment bar)\n- `app/src/test-setup.ts` — Modified — added vitest-canvas-mock import for Konva testing\n- `app/package.json` — Modified — added konva, react-konva, vitest-canvas-mock dependencies\n\n## Your Role in the Pipeline\n\nYou are the scout. After you finish, a **planner agent** reads your output in a fresh context with no memory of your exploration. It uses your findings to decompose this slice into executable tasks — deciding what files change, what order to build things, how to verify the work. Then **executor agents** build each task in isolated context windows.\n\nWrite for the planner, not for a human. The planner needs:\n- **What files exist and what they do** — so it can scope tasks to specific files\n- **Where the natural seams are** — where work divides into independent units\n- **What to build or prove first** — what's riskiest, what unblocks everything else\n- **How to verify the result** — what commands, tests, or checks confirm the slice works\n\nIf the research doc is vague, the planner will waste its context re-exploring code you already read. If it's precise, the planner can decompose immediately.\n\n## Calibrate Depth\n\nRead the slice title, the roadmap excerpt, and any milestone research above. Ask: does this slice involve unfamiliar technology, risky integration, novel architecture, or ambiguous requirements? Or is it straightforward application of known patterns to known code?\n\n- **Deep research** — new technology, unfamiliar APIs, risky integration, multiple viable approaches, or ambiguous scope. Explore broadly, look up docs, check libraries, investigate constraints. Write all template sections. This is the default when you're genuinely uncertain.\n- **Targeted research** — known technology but new to this codebase, or moderately complex integration. Explore the relevant code, check one or two libraries, identify constraints. Omit Don't Hand-Roll and Sources if nothing applies.\n- **Light research** — well-understood work using established patterns already in the codebase (wiring up existing APIs, adding standard UI components, CRUD operations, configuration changes). Read the relevant files to confirm the pattern, note any constraints, write Summary + Recommendation + Implementation Landscape. Skip the rest. A light research doc can be 15-20 lines. Don't manufacture pitfalls or risks for work that doesn't have them.\n\nAn honest \"this is straightforward, here's the pattern to follow\" is more valuable than invented complexity.\n\n## Steps\n\nResearch what this slice needs. Narrate key findings and surprises as you go — what exists, what's missing, what constrains the approach.\n0. If `REQUIREMENTS.md` was preloaded above, identify which Active requirements this slice owns or supports. Research should target these requirements — surfacing risks, unknowns, and implementation constraints that could affect whether the slice actually delivers them.\n1. Reference specific rules from loaded skills in your findings where they inform the implementation approach.\n2. **Skill Discovery (suggest):**\n Identify the key technologies, frameworks, and services this work depends on (e.g. Stripe, Clerk, Supabase, JUCE, SwiftUI).\n For each, check if a professional agent skill already exists:\n - First check `` in your system prompt — a skill may already be installed.\n - For technologies without an installed skill, run: `npx skills find \"\"`\n - Only consider skills that are **directly relevant** to core technologies — not tangentially related.\n - Evaluate results by install count and relevance to the actual work.\n - Note promising skills in your research output with their install commands, but do NOT install them.\n - The user will decide which to install.\n3. Explore relevant code for this slice's scope. For targeted exploration, use `rg`, `find`, and reads. For broad or unfamiliar subsystems, use `scout` to map the relevant area first.\n4. Use `resolve_library` / `get_library_docs` for unfamiliar libraries — skip this for libraries already used in the codebase\n5. **Web search budget:** You have a limited budget of web searches (max ~15 per session). Use them strategically — prefer `resolve_library` / `get_library_docs` for library documentation. Do NOT repeat the same or similar queries. If a search didn't find what you need, rephrase once or move on. Target 3-5 total web searches for a typical research unit.\n6. Use the **Research** output template from the inlined context above — include only sections that have real content. The template is already inlined above; do NOT attempt to read any template file from disk (there is no `templates/SLICE-RESEARCH.md` — the correct template is already present in this prompt).\n7. Call `gsd_summary_save` with `milestone_id: M002`, `slice_id: S03`, `artifact_type: \"RESEARCH\"`, and the full research markdown as `content` — the tool computes the file path and persists to both DB and disk.\n\nThe slice directory already exists at `.gsd/milestones/M002/slices/S03/`.

This is the first step before parsing the font, with methods for fetching from a URL (browser), reading from the filesystem (Node.js), or getting from an HTML file input (browser).\n\n```javascript\n// either from an URL\nconst buffer = fetch('/fonts/my.woff').then(res => res.arrayBuffer());\n// ... or from filesystem (node)\nconst buffer = require('fs').promises.readFile('./my.woff');\n// ... or from an (browser)\nconst buffer = document.getElementById('myfile').files[0].arrayBuffer();\n```\n\n--------------------------------\n\n### Parse ArrayBuffer into Font instance\n\nSource: https://github.com/opentypejs/opentype.js/blob/master/README.md\n\nIllustrates how to parse an `ArrayBuffer` (obtained from a font file) into an `opentype.js` `Font` instance. Examples cover both asynchronous contexts using `await` and promise-based handling for non-async environments.\n\n```javascript\n// if running in async context:\nconst font = opentype.parse(await buffer);\nconsole.log(font);\n\n// if not running in async context:\nbuffer.then(data => {\n const font = opentype.parse(data);\n console.log(font);\n})\n```\n\n--------------------------------\n\n### Create and Serialize OpenType Font\n\nSource: https://github.com/opentypejs/opentype.js/blob/master/docs/examples/creating-fonts.html\n\nDemonstrates the creation of a new `opentype.Font` object, populating it with defined glyphs and essential font metadata. It then shows how to serialize the font to an ArrayBuffer and parse it back, simulating font loading and manipulation.\n\n```javascript\nvar glyphs = [notdefGlyph, aGlyph, bGlyph];\nvar font = new opentype.Font({familyName: 'OpenTypeSans', styleName: 'Medium', unitsPerEm: 1000, ascender: 800, descender: -200, glyphs: glyphs});\nconsole.log(font.toTables());\nvar buffer = font.toArrayBuffer();\nvar font2 = opentype.parse(buffer);\n```\n\n--------------------------------\n\n### Load, Parse, and Render OpenType Font Glyphs\n\nSource: https://github.com/opentypejs/opentype.js/blob/master/docs/examples/reading-writing.html\n\nThis JavaScript code demonstrates the core functionality of opentype.js: fetching a font file, parsing its array buffer, and then iterating through its glyphs. For each glyph, it creates a dedicated canvas using `createGlyphCanvas` and draws the glyph, its points, and metrics.

(default: 2)\n optimize: apply some optimizations to the path data, e.g. removing unnecessary/duplicate commands (true/false, default: true)\n flipY: whether to flip the Y axis of the path data, because SVG and font paths use inverted Y axes. (true: calculate from bounding box, false: disable; default: true)\n flipYBase: Base value for the base flipping calculation. You'll probably want to calculate this from the font's ascender and descender values. (default: automatically calculate from the path data's bounding box)\n```\n\n--------------------------------\n\n### Path Object Properties\n\nSource: https://github.com/opentypejs/opentype.js/blob/master/README.md\n\nThe `Path` object holds properties defining its structure and appearance. `commands` stores the path segments, `fill` specifies the fill color (default 'black'), `stroke` defines the stroke color (default `null`), and `strokeWidth` sets the line thickness (default `1`).\n\n```APIDOC\nPath Properties:\n commands: The path commands. Each command is a dictionary containing a type and coordinates.\n fill: The fill color of the Path. Color is a string representing a CSS color. (default: 'black')\n stroke: The stroke color of the Path. Color is a string representing a CSS color. (default: null; the path will not be stroked)\n strokeWidth: The line thickness of the Path. (default: 1, but if stroke is null no stroke will be drawn)\n```\n\n--------------------------------\n\n### Path Command Types\n\nSource: https://github.com/opentypejs/opentype.js/blob/master/README.md\n\nThe `Path` object's `commands` array consists of dictionaries representing different drawing operations. These include 'Move To' (M) to start a new contour, 'Line To' (L) for straight lines, 'Curve To' (C) for cubic Bézier curves, 'Quad To' (Q) for quadratic Bézier curves, and 'Close' (Z) to close the current contour.\n\n```APIDOC\nPath Commands:\n Move To: {type: 'M', x: 100, y: 200}\n Line To: {type: 'L', x: 100, y: 200}\n Curve To: {type: 'C', x1: 0, y1: 50, x2: 100, y2: 200, x: 100, y: 200}\n Quad To: {type: 'Q', x1: 0, y1: 50, x: 100, y: 200}\n Close: {type: 'Z'}\n```\n\n--------------------------------\n\n### Path Bounding Box Calculation\n\nSource: https://github.com/opentypejs/opentype.js/blob/master/README.md\n\nThis method calculates the minimum bounding box for the `Path` object. It returns an `opentype.BoundingBox` object containing `x1`, `y1`, `x2`, and `y2` coordinates. For empty paths (e.g., space characters), all coordinates will be zero.\n\n```APIDOC\nPath.getBoundingBox()\n```\n\n--------------------------------\n\n### Convert Glyph Points to SVG Path Data\n\nSource: https://github.com/opentypejs/opentype.js/blob/master/docs/examples/font-editor.html\n\nThis function transforms an array of glyph points into an SVG path data string ('d' attribute value). It starts with a 'M' (moveTo) command for the first point and 'L' (lineTo) commands for subsequent points, applying a given scale and inverting the Y-axis (10 - Y) for SVG coordinate system compatibility. The path is closed with a 'Z' command.\n\n```javascript\nfunction toPathData(points, scale) {\n var d = '';\n for (var i = 0; i < points.length; i += 1) {\n if (i === 0) {\n d += 'M';\n } else {\n d += 'L';\n }\n d += points[i][0] * scale;\n d += ' ';\n d += (10 - points[i][1]) * scale;\n }\n d += 'Z';\n return d;\n}\n```"}],"details":{"libraryId":"/opentypejs/opentype.js","query":"Path toPathData toSVG Path object commands bounding box","tokens":4000,"cached":false,"truncated":false,"charCount":3833},"isError":false,"timestamp":1774503889220}} +{"type":"message","id":"374a4f7b","parentId":"296978f1","timestamp":"2026-03-26T05:44:49.223Z","message":{"role":"toolResult","toolCallId":"toolu_011QKwBxTBggLqR9r5jPtZyL","toolName":"bash","content":[{"type":"text","text":"1.3.4\n"}],"isError":false,"timestamp":1774503889220}} +{"type":"message","id":"45ebf36c","parentId":"374a4f7b","timestamp":"2026-03-26T05:44:56.067Z","message":{"role":"assistant","content":[{"type":"text","text":"Good — opentype.js 1.3.4 is the latest stable.

The work extends the existing discriminated union type system (D007/D008) by adding a `'text'` type, follows the established pattern of state management through `useCanvasState`, and renders text on the Konva canvas via `react-konva`'s `Text` component (for live editing) with conversion to `Path` components (for final output).\n\nThe core risk is opentype.js integration — specifically loading `.ttf`/`.otf` files from `app/public/fonts/`, parsing them into `Font` objects, and extracting accurate SVG path data via `Font.getPath().toPathData()`. The opentype.js API (v1.3.4) is well-documented and provides exactly the methods needed: `opentype.parse(arrayBuffer)` to load fonts, `Font.getPath(text, x, y, fontSize)` to generate path objects, and `Path.toPathData({flipY: true})` to produce SVG path `d` attributes compatible with Konva's `Path` component. This is a targeted research — the pattern is clear, the APIs are known, the extension points are explicit.\n\n## Recommendation\n\n**Approach:** Bundle 3-5 open-source fonts (e.g., Roboto, Open Sans, Lato, Oswald, Playfair Display — all Google Fonts with OFL license) in `app/public/fonts/`. Create a `fontService` utility that lazily loads and caches parsed `opentype.Font` objects. Add `TextObject` to the canvas type system. Render text on canvas using Konva's `Text` component for live editing, then use opentype.js `Font.getPath().toPathData()` to convert text to Konva `Path` elements when the user triggers \"Convert to Paths\". Build a `TextProperties` panel section in `ShapeProperties` for font family, size, letter spacing, and line height controls.\n\n**Why:** This approach separates concerns cleanly — Konva `Text` handles display and editing (with system font rendering), while opentype.js handles the precision text-to-path conversion needed for downstream kerf-aware export. Bundled fonts guarantee availability without network dependencies. The font service pattern keeps parsing async and cached, avoiding repeated ArrayBuffer fetches.\n\n## Implementation Landscape\n\n### Key Files\n\n- `app/src/types/canvas.ts` — Add `TextObject` interface and `'text'` to `CanvasObject` union. Fields: `text`, `fontFamily`, `fontSize`, `letterSpacing`, `lineHeight`, `fill`, `stroke`, `strokeWidth`, `width` (for text wrapping), `pathData` (optional — set after conversion to paths).\n- `app/src/utils/fontService.ts` — **New.** Font loading and caching service. Exports `loadFont(familyName)`, `getAvailableFonts()`, `textToPathData(text, fontFamily, fontSize, letterSpacing)`. Uses `opentype.parse()` internally. Caches parsed Font objects in a Map.\n- `app/src/hooks/useCanvasState.ts` — No changes needed to the hook itself — the existing `ADD_OBJECT`, `UPDATE_OBJECT`, `REMOVE_OBJECT` actions work with any `CanvasObject` union member. The `'text'` type flows through automatically.\n- `app/src/components/canvas/KonvaStage.tsx` — Add `case 'text':` to `renderObject()` switch. Import `Text` from `react-konva`. Also add `case 'text':` to `getObjWidth()`/`getObjHeight()` helpers. Add `'text'` to `CanvasTool` union and tool creation in `handleStageMouseDown`.\n- `app/src/components/canvas/CanvasToolbar.tsx` — Add text tool button (`T`) to TOOLS array.\n- `app/src/components/canvas/ShapeProperties.tsx` — Add `case 'text':` handling with text-specific property controls (font picker dropdown, font size, letter spacing, line height). Add \"Convert to Paths\" button that calls `textToPathData()`.\n- `app/src/components/canvas/ObjectPanel.tsx` — Add `text: 'T'` to `TYPE_ICONS` map.\n- `app/public/fonts/` — **New directory.** Place bundled `.ttf` font files here. They'll be served by Vite's static file server at `/fonts/`.\n- `app/src/utils/__tests__/fontService.test.ts` — **New.** Tests for font loading, caching, and text-to-path conversion.\n\n### Build Order\n\n1. **Font service utility** (`fontService.ts` + tests) — Prove that opentype.js loads fonts and extracts path data correctly. This is the riskiest piece — if path extraction doesn't produce accurate SVG `d` attributes compatible with Konva's `Path`, everything downstream breaks. Test with a real bundled font file.\n2. **Type system extension** (`canvas.ts`) — Add `TextObject` to discriminated union. Mechanical — just type definitions. Must happen before any component work.\n3. **Canvas rendering + tool** (KonvaStage, CanvasToolbar, ObjectPanel) — Add text tool, `case 'text':` rendering via Konva `Text`, and tool icon. This wires text objects into the canvas without any property editing.\n4. **Properties panel + convert-to-paths** (ShapeProperties) — Font picker, size/spacing controls, \"Convert to Paths\" button. The conversion replaces the `TextObject` with one or more `PathObject` entries (new type — a `Path` rendered via Konva `Path` from the `d` attribute). Or, more simply, it replaces the text object with an `ImageObject` using an SVG data URL built from the path data.\n\n**Why this order:** Font service is the only unknown — validating opentype.js path extraction first de-risks everything. Types must exist before components compile. Rendering before properties follows the pattern established in S02.\n\n### Verification Approach\n\n1. **Unit tests:** `fontService.test.ts` — load a bundled font, call `textToPathData(\"Hello\", \"Roboto\", 48, 0)`, assert the returned string starts with `M` and contains path commands. Test caching (second call doesn't re-fetch). Test error handling for missing font.\n2. **Type safety:** `npx tsc --noEmit` — zero errors with the new `'text'` type added to all switch statements.\n3. **Existing tests pass:** `npx vitest run` — all 71 existing tests still pass (no regressions).\n4. **New component tests:** Test text object creation via tool, text property updates, convert-to-paths action.\n5. **Full test suite:** `cd app && npx vitest run --reporter=verbose` — all tests pass.\n\n## Don't Hand-Roll\n\n| Problem | Existing Solution | Why Use It |\n|---------|------------------|------------|\n| Font file parsing + glyph extraction | `opentype.js` (v1.3.4) | Industry-standard OpenType parser for JavaScript. `Font.getPath()` → `Path.toPathData()` gives exact SVG path data for text. Has TypeScript types. Already identified in roadmap. |\n| Text rendering on canvas | `react-konva` `Text` component | Already in the project. Handles text display, wrapping, and basic styling. Used for live editing before conversion. |\n| Path rendering on canvas | `react-konva` `Path` component | Already imported in KonvaStage.tsx. Renders SVG path `d` attributes. Used for text-to-path conversion output. |\n\n## Constraints\n\n- **opentype.js loads fonts from ArrayBuffer** — must `fetch()` font files as ArrayBuffer, then call `opentype.parse()`. Cannot use CSS `@font-face` for path extraction — that only gives rendering, not glyph geometry.\n- **Konva `Text` uses system/CSS fonts, not opentype.js** — for live canvas display, Konva renders text using the browser's text engine with `fontFamily` CSS. The opentype.js font and the Konva display font must match visually. This means the bundled fonts must also be loaded via `@font-face` CSS for Konva rendering.\n- **Path.toPathData() needs `flipY: true`** — font coordinate systems have Y increasing upward, SVG/canvas have Y increasing downward. The `flipY` option handles this automatically.\n- **TypeScript strict mode with `noUnusedLocals` and `noUnusedParameters`** — all new code must pass strict checks. The `erasableSyntaxOnly: true` flag means type-only imports must use `import type`.\n- **`CanvasTool` type is defined in KonvaStage.tsx** — adding `'text'` requires updating the union type there, which affects CanvasToolbar's import.\n\n## Common Pitfalls\n\n- **Font not loaded for Konva rendering** — If the `@font-face` CSS isn't loaded before Konva renders the `Text` node, it falls back to a default font. Use `document.fonts.ready` or `FontFace.load()` API to ensure CSS font is loaded before rendering.\n- **opentype.js `getPath()` y parameter is baseline, not top** — The `y` argument is the text baseline position, not the top of the text bounding box. To position text at a specific y coordinate, compute `y + font.ascender * (fontSize / font.unitsPerEm)`.\n- **Letter spacing not built into `getPath()`** — opentype.js handles kerning automatically but has no letter-spacing parameter. Must implement letter spacing by calling `Font.charToGlyph()` per character and manually advancing the x position by `glyph.advanceWidth * (fontSize / unitsPerEm) + letterSpacing`.\n- **Convert-to-paths replaces the text object** — After conversion, the text is no longer editable as text. This should be a destructive action with user confirmation.\n- **Font file size** — Each `.ttf` file is 100-500KB. Bundling 3-5 fonts adds 0.5-2.5MB to public assets. This is acceptable for a design tool but shouldn't be imported into the JS bundle — serve from `public/`.\n\n## Open Risks\n\n- **Letter spacing implementation complexity** — If per-character path generation for letter spacing proves complex, it could be deferred to a follow-up, offering only kerning (built-in to opentype.js) initially.\n- **Multi-line text path conversion** — `Font.getPath()` produces a single path for one line of text. Multi-line text requires splitting by line breaks and offsetting each line's y position by `lineHeight * fontSize`. This is straightforward but adds implementation surface.\n- **Font licensing for bundled fonts** — Must use OFL (Open Font License) or Apache-licensed fonts only. Google Fonts catalog fonts (Roboto, Open Sans, etc.) are safe. Verify license files are included.\n","milestone_id":"M002","slice_id":"S03"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":2796,"cacheRead":92113,"cacheWrite":416,"totalTokens":95326,"cost":{"input":0.000005,"output":0.0699,"cacheRead":0.0460565,"cacheWrite":0.0026000000000000003,"total":0.11856150000000001}},"stopReason":"toolUse","timestamp":1774503936507}} +{"type":"message","id":"fbe85fc3","parentId":"e5e6b514","timestamp":"2026-03-26T05:46:44.531Z","message":{"role":"toolResult","toolCallId":"toolu_01CA8sNaJsLJGQCdPJjU6JFq","toolName":"gsd_summary_save","content":[{"type":"text","text":"Saved RESEARCH artifact to milestones/M002/slices/S03/S03-RESEARCH.md"}],"details":{"operation":"save_summary","path":"milestones/M002/slices/S03/S03-RESEARCH.md","artifact_type":"RESEARCH"},"isError":false,"timestamp":1774504004529}} +{"type":"message","id":"640ec84d","parentId":"fbe85fc3","timestamp":"2026-03-26T05:46:47.336Z","message":{"role":"assistant","content":[{"type":"text","text":"Slice S03 researched."}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":11,"cacheRead":92529,"cacheWrite":2834,"totalTokens":95375,"cost":{"input":0.000005,"output":0.000275,"cacheRead":0.0462645,"cacheWrite":0.017712500000000003,"total":0.06425700000000001}},"stopReason":"stop","timestamp":1774504004530}} diff --git a/.gsd/activity/032-plan-slice-M002-S03.jsonl b/.gsd/activity/032-plan-slice-M002-S03.jsonl new file mode 100644 index 0000000..c4a3b4c --- /dev/null +++ b/.gsd/activity/032-plan-slice-M002-S03.jsonl @@ -0,0 +1,29 @@ +{"type":"thinking_level_change","id":"2c0b129b","parentId":null,"timestamp":"2026-03-26T05:46:47.602Z","thinkingLevel":"off"} +{"type":"custom_message","customType":"gsd-auto","content":"You are executing GSD auto-mode.\n\n## Working Directory\n\nYour working directory is `/home/aux/development/xpltdco/kerf-engine`.

If `REQUIREMENTS.md` was preloaded above, identify which Active requirements the roadmap says this slice owns or supports. These are the requirements this plan must deliver — every owned requirement needs at least one task that directly advances it, and verification must prove the requirement is met.\n1. Read the templates:\n - `~/.gsd/agent/extensions/gsd/templates/plan.md`\n - `~/.gsd/agent/extensions/gsd/templates/task-plan.md`\n2. Record the installed skills you expect executors to use in each task plan's `skills_used` frontmatter.\n3. Define slice-level verification — the objective stopping condition for this slice:\n - For non-trivial slices: plan actual test files with real assertions. Name the files.\n - For simple slices: executable commands or script assertions are fine.\n - If the project is non-trivial and has no test framework, the first task should set one up.\n - If this slice establishes a boundary contract, verification must exercise that contract.\n4. **For non-trivial slices only** — plan observability, proof level, and integration closure:\n - Include `Observability / Diagnostics` for backend, integration, async, stateful, or UI slices where failure diagnosis matters.\n - Fill `Proof Level` and `Integration Closure` when the slice crosses runtime boundaries or has meaningful integration concerns.\n - **Omit these sections entirely for simple slices** where they would all be \"none\" or trivially obvious.\n5. Decompose the slice into tasks, each fitting one context window. Each task needs:\n - a concrete, action-oriented title\n - the inline task entry fields defined in the plan.md template (Why / Files / Do / Verify / Done when)\n - a matching task plan file with description, steps, must-haves, verification, inputs, and expected output\n - **Inputs and Expected Output must list concrete backtick-wrapped file paths** (e.g. `` `src/types.ts` ``). These are machine-parsed to derive task dependencies — vague prose without paths breaks parallel execution. Every task must have at least one output file path.\n - Observability Impact section **only if the task touches runtime boundaries, async flows, or error paths** — omit it otherwise\n6. **Persist planning state through `gsd_plan_slice`.** Call it with the full slice planning payload (goal, demo, must-haves, verification, tasks, and metadata). The tool inserts all tasks in the same transaction, writes to the DB, and renders `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/S03-PLAN.md` and `.gsd/milestones/M002/slices/S03/tasks/T##-PLAN.md` files automatically. Do **not** call `gsd_plan_task` separately — `gsd_plan_slice` handles task persistence. Do **not** rely on direct `PLAN.md` writes as the source of truth; the DB-backed tool is the canonical write path for slice and task planning state.\n7. **Self-audit the plan.** Walk through each check — if any fail, fix the plan files before moving on:\n - **Completion semantics:** If every task were completed exactly as written, the slice goal/demo should actually be true.\n - **Requirement coverage:** Every must-have in the slice maps to at least one task. No must-have is orphaned. If `REQUIREMENTS.md` exists, every Active requirement this slice owns maps to at least one task.\n - **Task completeness:** Every task has steps, must-haves, verification, inputs, and expected output — none are blank or vague. Inputs and Expected Output list backtick-wrapped file paths, not prose descriptions.\n - **Dependency correctness:** Task ordering is consistent. No task references work from a later task.\n - **Key links planned:** For every pair of artifacts that must connect, there is an explicit step that wires them.\n - **Scope sanity:** Target 2–5 steps and 3–8 files per task. 10+ steps or 12+ files — must split. Each task must be completable in a single fresh context window.\n - **Feature completeness:** Every task produces real, user-facing progress — not just internal scaffolding.\n10.

Fields: `text`, `fontFamily`, `fontSize`, `letterSpacing`, `lineHeight`, `fill`, `stroke`, `strokeWidth`, `width` (for text wrapping), `pathData` (optional — set after conversion to paths).\n- `app/src/utils/fontService.ts` — **New.** Font loading and caching service. Exports `loadFont(familyName)`, `getAvailableFonts()`, `textToPathData(text, fontFamily, fontSize, letterSpacing)`. Uses `opentype.parse()` internally. Caches parsed Font objects in a Map.\n- `app/src/hooks/useCanvasState.ts` — No changes needed to the hook itself — the existing `ADD_OBJECT`, `UPDATE_OBJECT`, `REMOVE_OBJECT` actions work with any `CanvasObject` union member. The `'text'` type flows through automatically.\n- `app/src/components/canvas/KonvaStage.tsx` — Add `case 'text':` to `renderObject()` switch. Import `Text` from `react-konva`. Also add `case 'text':` to `getObjWidth()`/`getObjHeight()` helpers. Add `'text'` to `CanvasTool` union and tool creation in `handleStageMouseDown`.\n- `app/src/components/canvas/CanvasToolbar.tsx` — Add text tool button (`T`) to TOOLS array.\n- `app/src/components/canvas/ShapeProperties.tsx` — Add `case 'text':` handling with text-specific property controls (font picker dropdown, font size, letter spacing, line height). Add \"Convert to Paths\" button that calls `textToPathData()`.\n- `app/src/components/canvas/ObjectPanel.tsx` — Add `text: 'T'` to `TYPE_ICONS` map.\n- `app/public/fonts/` — **New directory.** Place bundled `.ttf` font files here. They'll be served by Vite's static file server at `/fonts/`.\n- `app/src/utils/__tests__/fontService.test.ts` — **New.** Tests for font loading, caching, and text-to-path conversion.\n\n### Build Order\n\n1. **Font service utility** (`fontService.ts` + tests) — Prove that opentype.js loads fonts and extracts path data correctly. This is the riskiest piece — if path extraction doesn't produce accurate SVG `d` attributes compatible with Konva's `Path`, everything downstream breaks. Test with a real bundled font file.\n2. **Type system extension** (`canvas.ts`) — Add `TextObject` to discriminated union. Mechanical — just type definitions. Must happen before any component work.\n3. **Canvas rendering + tool** (KonvaStage, CanvasToolbar, ObjectPanel) — Add text tool, `case 'text':` rendering via Konva `Text`, and tool icon. This wires text objects into the canvas without any property editing.\n4. **Properties panel + convert-to-paths** (ShapeProperties) — Font picker, size/spacing controls, \"Convert to Paths\" button. The conversion replaces the `TextObject` with one or more `PathObject` entries (new type — a `Path` rendered via Konva `Path` from the `d` attribute). Or, more simply, it replaces the text object with an `ImageObject` using an SVG data URL built from the path data.\n\n**Why this order:** Font service is the only unknown — validating opentype.js path extraction first de-risks everything. Types must exist before components compile. Rendering before properties follows the pattern established in S02.\n\n### Verification Approach\n\n1. **Unit tests:** `fontService.test.ts` — load a bundled font, call `textToPathData(\"Hello\", \"Roboto\", 48, 0)`, assert the returned string starts with `M` and contains path commands. Test caching (second call doesn't re-fetch). Test error handling for missing font.\n2. **Type safety:** `npx tsc --noEmit` — zero errors with the new `'text'` type added to all switch statements.\n3. **Existing tests pass:** `npx vitest run` — all 71 existing tests still pass (no regressions).\n4. **New component tests:** Test text object creation via tool, text property updates, convert-to-paths action.\n5. **Full test suite:** `cd app && npx vitest run --reporter=verbose` — all tests pass.\n\n## Don't Hand-Roll\n\n| Problem | Existing Solution | Why Use It |\n|---------|------------------|------------|\n| Font file parsing + glyph extraction | `opentype.js` (v1.3.4) | Industry-standard OpenType parser for JavaScript. `Font.getPath()` → `Path.toPathData()` gives exact SVG path data for text. Has TypeScript types. Already identified in roadmap. |\n| Text rendering on canvas | `react-konva` `Text` component | Already in the project. Handles text display, wrapping, and basic styling. Used for live editing before conversion. |\n| Path rendering on canvas | `react-konva` `Path` component | Already imported in KonvaStage.tsx. Renders SVG path `d` attributes. Used for text-to-path conversion output. |\n\n## Constraints\n\n- **opentype.js loads fonts from ArrayBuffer** — must `fetch()` font files as ArrayBuffer, then call `opentype.parse()`. Cannot use CSS `@font-face` for path extraction — that only gives rendering, not glyph geometry.\n- **Konva `Text` uses system/CSS fonts, not opentype.js** — for live canvas display, Konva renders text using the browser's text engine with `fontFamily` CSS. The opentype.js font and the Konva display font must match visually. This means the bundled fonts must also be loaded via `@font-face` CSS for Konva rendering.\n- **Path.toPathData() needs `flipY: true`** — font coordinate systems have Y increasing upward, SVG/canvas have Y increasing downward. The `flipY` option handles this automatically.\n- **TypeScript strict mode with `noUnusedLocals` and `noUnusedParameters`** — all new code must pass strict checks. The `erasableSyntaxOnly: true` flag means type-only imports must use `import type`.\n- **`CanvasTool` type is defined in KonvaStage.tsx** — adding `'text'` requires updating the union type there, which affects CanvasToolbar's import.\n\n## Common Pitfalls\n\n- **Font not loaded for Konva rendering** — If the `@font-face` CSS isn't loaded before Konva renders the `Text` node, it falls back to a default font. Use `document.fonts.ready` or `FontFace.load()` API to ensure CSS font is loaded before rendering.\n- **opentype.js `getPath()` y parameter is baseline, not top** — The `y` argument is the text baseline position, not the top of the text bounding box. To position text at a specific y coordinate, compute `y + font.ascender * (fontSize / font.unitsPerEm)`.\n- **Letter spacing not built into `getPath()`** — opentype.js handles kerning automatically but has no letter-spacing parameter. Must implement letter spacing by calling `Font.charToGlyph()` per character and manually advancing the x position by `glyph.advanceWidth * (fontSize / unitsPerEm) + letterSpacing`.\n- **Convert-to-paths replaces the text object** — After conversion, the text is no longer editable as text. This should be a destructive action with user confirmation.\n- **Font file size** — Each `.ttf` file is 100-500KB. Bundling 3-5 fonts adds 0.5-2.5MB to public assets. This is acceptable for a design tool but shouldn't be imported into the JS bundle — serve from `public/`.\n\n## Open Risks\n\n- **Letter spacing implementation complexity** — If per-character path generation for letter spacing proves complex, it could be deferred to a follow-up, offering only kerning (built-in to opentype.js) initially.\n- **Multi-line text path conversion** — `Font.getPath()` produces a single path for one line of text. Multi-line text requires splitting by line breaks and offsetting each line's y position by `lineHeight * fontSize`. This is straightforward but adds implementation surface.\n- **Font licensing for bundled fonts** — Must use OFL (Open Font License) or Apache-licensed fonts only. Google Fonts catalog fonts (Roboto, Open Sans, etc.) are safe. Verify license files are included.\n\n---\n\n### Decisions\nSource: `.gsd/DECISIONS.md`\n\n# Decisions Register\n\n\n\n| # | When | Scope | Decision | Choice | Rationale | Revisable? | Made By |\n|---|------|-------|----------|--------|-----------|------------|---------|\n| D001 | | architecture | Engine/App architectural relationship | Engine is standalone module, App is a consumer. Zero coupling — App calls Engine only via HTTP API. | Engine is proprietary IP that must be embeddable into future applications independently. Clean input/output contracts enable this. | No | human |\n| D002 | | architecture | Build order and gating strategy | Build Engine first (M001), then App canvas (M002), then Export+Deploy+Embed (M003). Human checkpoints gate each transition. | Brief explicitly mandates: validate engine output quality before building canvas UI, validate canvas before export/deploy. Engine is the hardest and most valuable piece. | No | human |\n| D003 | | engine | Post-processing replaces regex metadata extraction | postprocess_svg() pipeline replaces old _extract_svg_metadata() regex approach; all SVG paths are parsed into structured PathInfo objects with coordinates, area, island status | Structured path data is needed for DXF/JSON output generation, RDP simplification, and island detection. XML parsing is now necessary since we need actual coordinate data, not just counts. This supersedes D003's regex approach. | No | agent |\n| D004 | | architecture | Engine Docker image build strategy | Multi-stage build: builder stage compiles pypotrace with build-essential/libagg-dev/libpotrace-dev, runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl). Only engine source is copied — no App code. | Multi-stage keeps the runtime image small by excluding build tools. Copying only engine source enforces the Engine/App separation (D001). curl is included for Docker HEALTHCHECK. | Yes | agent |\n| D005 | | architecture | Frontend technology stack for Kerf App | Vite + React + TypeScript with plain CSS modules, Vitest for testing, raw fetch + FormData for engine API calls, no UI framework for V1 | Minimal dependency surface for a tool that needs fast iteration. The engine API uses multipart/form-data which works naturally with native fetch + FormData. CSS modules avoid global style conflicts without adding a framework. Vitest integrates natively with Vite's transform pipeline. No UI library needed — the app has a focused interface with ~8 components. | Yes | agent |\n| D006 | | frontend | React hook params stabilization strategy for useDebouncedTrace | JSON.stringify params in useEffect deps array, single-effect architecture | useCallback-based triggerTrace with object params caused infinite re-render loops because React creates new object references each render. JSON.stringify converts params to a stable string for dependency comparison, eliminating the need for callers to useMemo their params objects. Simpler API surface and no re-render bugs. | Yes | agent |\n| D007 | | architecture | Canvas object type system design | Discriminated union on `type` field: 'rect' \\| 'circle' \\| 'ellipse' \\| 'line' \\| 'image'. All objects share BaseCanvasObject (id, name, x, y, visible, locked, stroke, fill, opacity). Type-specific fields via intersection types. | TypeScript discriminated unions enable exhaustive type narrowing in switch/if statements, catching missing cases at compile time. Shared base keeps CRUD operations generic while type-specific panels (ShapeProperties) safely narrow to access unique fields. 'text' type will be added in S03. | Yes | agent |\n\n---\n\n### Project Knowledge\nSource: `.gsd/KNOWLEDGE.md`\n\n# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit. Add entries when you discover something worth remembering.\n\n## Rules\n\n| # | Scope | Rule | Why | Added |\n|---|-------|------|-----|-------|\n\n## Patterns\n\n| # | Pattern | Where | Notes |\n|---|---------|-------|-------|\n| P001 | Test images generated programmatically via numpy | engine/tests/ | No fixture image files checked in. Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n| P003 | PostProcessResult is the universal intermediate representation | engine/pipeline/postprocess.py → engine/output/ | All output generators (DXF, JSON, SVG) consume PostProcessResult. Never generate output directly from raw SVG strings. |\n| P004 | _format_response() for consistent multi-format API responses | engine/api/routes.py | DXF returns binary Response with X-Kerf-Metadata header; SVG/JSON return JSON envelopes. Use _format_response() for both /engine/trace and /engine/simplify. |\n| P005 | Preset-driven pipeline: resolve_params() merges preset → user | engine/presets/loader.py, engine/api/routes.py | Presets define defaults for all pipeline stages. User params override. Mode comes from preset unless user explicitly sets it. |\n| P006 | JSON.stringify for React hook dependency stabilization | app/src/hooks/useDebouncedTrace.ts | Object params in useEffect deps cause infinite loops (new ref each render). Stringify the params object and use the string in the deps array. Avoids requiring callers to useMemo. |\n| P007 | Vite dev proxy for engine API calls | app/vite.config.ts | `/engine/*` requests proxy to `http://localhost:8000`. API client uses relative URLs (`/engine/presets`). No CORS issues in dev because same-origin via proxy. |\n| P008 | CSS modules for views, global App.css for shared component styles | app/src/views/*.module.css, app/src/App.css | View-specific layout in CSS modules avoids conflicts. Shared styles (upload zone, preset cards, buttons) in App.css for cross-component reuse. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them. Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003). All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n| L007 | Docker build context must be project root, not engine/ | Dockerfile.engine uses `COPY engine/...` paths relative to project root | Always build with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` from project root | Docker |\n| L008 | Engine container has dual health endpoints | /health on root (main.py) and /engine/health on router (routes.py) both exist | Use /engine/health for Docker HEALTHCHECK and external probes for namespace consistency | engine API, Docker |\n| L009 | useCallback-based triggerTrace caused infinite re-render loops | Object params create new references each render, retriggering useEffect even when values are unchanged | Restructure hook to use single useEffect with JSON.stringify(params) in dependency array instead of useCallback-based approach | app hooks, React |\n| L010 | jest-canvas-mock crashes in Vitest with \"ReferenceError: jest is not defined\" | jest-canvas-mock internally calls jest.fn() in createImageBitmap.js — Jest globals don't exist in Vitest | Use vitest-canvas-mock (a Vitest-compatible fork) instead.

Built the central `useCanvasState` hook using a useReducer + useRef pattern — reducer drives re-renders for current state, ref holds undo/redo history stacks without triggering renders. Select/deselect are excluded from the undo stack (UI-only concern). History is capped at 50 entries. Created artboard shape utilities (shield/pennant SVG paths, dimension presets, unit conversion), 9 pure alignment/distribute functions, and the `ArtboardSetup` modal component. Installed konva, react-konva, and vitest-canvas-mock. 48 new tests passing.\n\n**T02 — Rendering Layer:** Created `KonvaStage` rendering artboard backgrounds (Rect/Circle/Ellipse/Path based on shape config), mapping all canvas objects to Konva primitives with drag/transform handlers, Transformer synced to selected nodes, and rubber-band multi-select rectangle. Built `DesignCanvas` view container with ResizeObserver-driven sizing, artboard setup flow, and SVG import (Blob URL → Image element → Konva.Image with auto-scale). Wired into `App.tsx` to receive real svgData/traceMetadata props from View 1.\n\n**T03 — Panel System:** Built four panel components: `ObjectPanel` (layer list in reverse z-order with drag reorder, visibility/lock toggles, rename), `AlignmentBar` (6 alignment + 2 distribute + center-on-artboard), `CanvasToolbar` (tool switcher, undo/redo, grid toggle, zoom controls), and `ShapeProperties` (stroke/fill/dimensions/line-style editing with discriminated union narrowing). All wired to useCanvasState in DesignCanvas.\n\n**T04 — Shortcuts & Integration:** Added window-level keyboard shortcuts (Ctrl+Z undo, Ctrl+Shift+Z redo, Delete/Backspace remove, Escape deselect, Ctrl+A select all) with activeElement guard to skip input fields. Verified full integration: View 1 → Use This → Artboard Setup → Canvas with imported SVG. All 71 tests pass, zero TypeScript errors.\n\n## Verification\n\nRan `cd app && npx vitest run --reporter=verbose` — 71 tests pass across 6 test files, 0 failures (exit 0). Ran `cd app && npx tsc --noEmit` — zero type errors under strict mode with noUnusedLocals/noUnusedParameters (exit 0).\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nUsed vitest-canvas-mock instead of jest-canvas-mock (plan specified jest-canvas-mock but it crashes in Vitest because it internally calls jest.fn()). This was identified in T01 and recorded as L010 in KNOWLEDGE.md.\n\n## Known Limitations\n\nCanvas components (KonvaStage, DesignCanvas panels) do not have dedicated unit tests — they were verified via TypeScript compilation and manual integration. Konva rendering in jsdom is limited since canvas operations are mocked. Drag-to-reorder in ObjectPanel uses simple index swapping, not full drag-and-drop library.\n\n## Follow-ups\n\nS03 will add 'text' type to the CanvasObject discriminated union and integrate opentype.js for font loading and text-to-path conversion. ShapeProperties panel will need a text-specific section. The canvas object type system (D008) was designed to accommodate this extension.\n\n## Files Created/Modified\n\n- `app/src/types/canvas.ts` — New — discriminated union type system for canvas objects (rect, circle, ellipse, line, image), ArtboardConfig, CanvasState, and CanvasAction types\n- `app/src/hooks/useCanvasState.ts` — New — central state management hook with useReducer+useRef for CRUD, selection, undo/redo, reorder, visibility/lock\n- `app/src/hooks/__tests__/useCanvasState.test.ts` — New — 20 tests covering all useCanvasState operations including undo/redo edge cases\n- `app/src/utils/artboardShapes.ts` — New — artboard shape presets, shield/pennant SVG path generators, toPx/fromPx unit conversion, artboardClipPath\n- `app/src/utils/__tests__/artboardShapes.test.ts` — New — 15 tests for artboard presets, path generation, unit conversion, clip paths\n- `app/src/utils/alignment.ts` — New — 9 pure alignment/distribute/center functions for canvas objects\n- `app/src/utils/__tests__/alignment.test.ts` — New — 13 tests for alignment, distribution, and center-on-artboard\n- `app/src/components/canvas/ArtboardSetup.tsx` — New — modal for artboard shape/size/unit selection on entering canvas view\n- `app/src/components/canvas/KonvaStage.tsx` — New — Konva Stage+Layer rendering artboard, all object types, Transformer, rubber-band selection\n- `app/src/components/canvas/ObjectPanel.tsx` — New — layer management panel with z-order list, reorder, visibility/lock toggles, rename\n- `app/src/components/canvas/AlignmentBar.tsx` — New — alignment and distribution toolbar consuming alignment utils\n- `app/src/components/canvas/CanvasToolbar.tsx` — New — tool switcher, undo/redo, grid toggle, zoom controls\n- `app/src/components/canvas/ShapeProperties.tsx` — New — property editor for selected shape (stroke, fill, dimensions, line style, opacity)\n- `app/src/views/DesignCanvas.tsx` — New — View 2 container wiring KonvaStage + all panels to useCanvasState, SVG import, keyboard shortcuts\n- `app/src/views/DesignCanvas.module.css` — New — CSS module for DesignCanvas layout\n- `app/src/App.tsx` — Modified — wired DesignCanvas with svgData/traceMetadata props, removed underscore prefixes\n- `app/src/App.css` — Modified — added comprehensive canvas UI styles (toolbar, panels, artboard setup, shape properties, alignment bar)\n- `app/src/test-setup.ts` — Modified — added vitest-canvas-mock import for Konva testing\n- `app/package.json` — Modified — added konva, react-konva, vitest-canvas-mock dependencies\n\n## Your Role in the Pipeline\n\nYou have full tool access. Before decomposing, explore the relevant code to ground your plan in reality.\n\n### Verify Roadmap Assumptions\n\nCheck prior slice summaries (inlined above as dependency summaries, if present). If prior slices discovered constraints, changed approaches, or flagged fragility, adjust your plan accordingly. The roadmap description may be stale — verify it against the current codebase state.\n\n### Explore Slice Scope\n\nRead the code files relevant to this slice. Confirm the roadmap's description of what exists, what needs to change, and what boundaries apply. Use `rg`, `find`, and targeted reads.\n\n### Source Files\n\n- **Decisions**: `.gsd/DECISIONS.md`\n- **Roadmap**: `.gsd/milestones/M002/M002-ROADMAP.md`\n- **Slice Research**: `.gsd/milestones/M002/slices/S03/S03-RESEARCH.md`\n\nIf slice research exists (inlined above), trust those findings and skip redundant exploration.\n\nAfter you finish, **executor agents** implement each task in isolated fresh context windows. They see only their task plan, the slice plan excerpt (goal/demo/verification), and compressed summaries of prior tasks. They do not see the research doc, the roadmap, or REQUIREMENTS.md. Everything an executor needs must be in the task plan itself — file paths, specific steps, expected inputs and outputs.\n\nNarrate your decomposition reasoning — why you're grouping work this way, what risks are driving the order, what verification strategy you're choosing and why.

This must come first to de-risk.\n\n2. **Type system + canvas rendering** — Adding `TextObject` to the discriminated union, then wiring text rendering into KonvaStage, CanvasToolbar, ObjectPanel. These are tightly coupled — changing the type union immediately requires updating all switch statements (TypeScript strict mode with `noFallthroughCasesInSwitch`).\n\n3. **Text properties panel + convert-to-paths** — The ShapeProperties panel needs text-specific controls (font picker, size, spacing), plus the \"Convert to Paths\" button that uses the font service.\n\nI'll group this into **3 tasks**:\n\n- **T01**: Font service utility + bundled fonts + tests. This is standalone — proves opentype.js works, de-risks the whole slice. Also installs opentype.js dependency.\n- **T02**: Type system extension + canvas integration (KonvaStage text rendering, toolbar text tool, ObjectPanel icon, DesignCanvas wiring). This is the bulk mechanical integration — touching many files but all following established patterns from S02. \n- **T03**: Text properties panel in ShapeProperties + convert-to-paths action.

the checklist:\n\n**Completion semantics:** If T01 delivers the font service with bundled fonts and tests, T02 wires text objects into the canvas type system and rendering, and T03 adds the property

picker, change size/spacing, convert text to paths — paths match original glyphs\") are both true. ✅\n\n**Requirement coverage:** No Active requirements are assigned to this slice — confirmed by \"Requirements Advanced: None\" in the unit brief. Each must-have maps to at least one task: font service → T01, type system → T02, canvas rendering → T02, property controls → T03, convert-to-paths → T03, bundled fonts → T01, tests pass → all three. ✅\n\n**Task completeness:** All three tasks have Steps (in description), Must-haves (implied by description constraints), Verification commands, Inputs (backtick file paths), and Expected Output (backtick file paths). ✅\n\n**Dependency correctness:** T01 is standalone (font service). T02 depends on T01's existence only for the @font-face CSS (already in App.css from T01) but can proceed independently — the type system and component changes don't import fontService. T03 explicitly depends on both T01 (fontService) and T02 (TextObject type + ShapeProperties). Sequential order is correct. ✅\n\n**Key links planned:** fontService → ShapeProperties (T03 imports fontService from T01). TextObject type → KonvaStage/ShapeProperties/CanvasToolbar/ObjectPanel (T02 wires all of these). DesignCanvas → ShapeProperties callbacks (T03 extends the prop interface). ✅\n\n**Scope sanity:** T01: ~5 steps, ~5 files. T02: ~5 files touched with switch-statement extensions. T03: ~2 files. All well under limits. ✅\n\n**Feature completeness:** Every task produces user-facing progress. T01: fonts available. T02: text tool usable on canvas. T03: text editing + conversion. ✅\n\nThe plan is sound.

The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/S03-PLAN.md`\n- Task plan source: `.gsd/milestones/M002/slices/S03/tasks/T01-PLAN.md`\n- Prior task summaries in this slice:\n- (no prior tasks)\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/tasks/T01-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/tasks/T01-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T01 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M002/slices/S03/S03-PLAN.md`\n**Goal:** Add text objects to the design canvas with font loading from bundled fonts, property editing (font family, size, letter spacing, line height), and text-to-path conversion using opentype.js.\n**Demo:** After this: Add text objects, select fonts from picker, change size/spacing, convert text to paths — paths match original glyphs\n\n## UNIT: Execute Task T01 (\"Build font service with opentype.js, bundle fonts, and add unit tests\") — Slice S03 (\"Text System + Font Loading\"), Milestone M002\n\n## Resume State\n- No continue file present.

Wire text objects into all canvas components: KonvaStage (render via Konva Text + case in getObjWidth/getObjHeight + text tool creation in handleStageMouseDown), CanvasToolbar (add 'text' to CanvasTool union and TOOLS array), ObjectPanel (add 'text' icon to TYPE_ICONS), and DesignCanvas (pass through). This follows the exact pattern established in S02 for adding object types.\n\n## Key Implementation Details\n- TextObject interface: extends BaseCanvasObject with type: 'text', text: string, fontFamily: string, fontSize: number, letterSpacing: number, lineHeight: number, fill: string, stroke: string, strokeWidth: number, width: number (for wrapping)\n- CanvasTool union in KonvaStage.tsx must add 'text' — this is imported by CanvasToolbar\n- KonvaStage renderObject switch: case 'text' renders from react-konva with fontFamily, fontSize, fill, stroke, strokeWidth, width, letterSpacing, lineHeight props\n- KonvaStage handleStageMouseDown switch: case 'text' creates a TextObject with defaults (text: 'Text', fontFamily: 'Roboto', fontSize: 24, letterSpacing: 0, lineHeight: 1.2)\n- KonvaStage getObjWidth for text: use obj.width (wrapping width) or estimate from fontSize * text.length * 0.6\n- KonvaStage getObjHeight for text: obj.fontSize * obj.lineHeight\n- KonvaStage onTransformEnd for text: scale width, keep fontSize unchanged (text wraps to new width)\n- ObjectPanel TYPE_ICONS: text → 'T'\n- ShapeProperties getWidth/getHeight: add case 'text' returning obj.width and obj.fontSize * obj.lineHeight\n- All switch statements must be exhaustive — TypeScript noFallthroughCasesInSwitch enforces this\n- TypeScript strict mode — no unused locals/params, erasableSyntaxOnly, use import type\n - Estimate: 1h\n - Files: app/src/types/canvas.ts, app/src/components/canvas/KonvaStage.tsx, app/src/components/canvas/CanvasToolbar.tsx, app/src/components/canvas/ObjectPanel.tsx, app/src/components/canvas/ShapeProperties.tsx\n - Verify: cd app && npx tsc --noEmit && npx vitest run --reporter=verbose\n- [ ] **T03: Build text properties panel and convert-to-paths action in ShapeProperties** — Add text-specific property controls to ShapeProperties and implement the 'Convert to Paths' action that replaces a TextObject with path-based objects using fontService.textToPathData().\n\n## Text Property Controls (in ShapeProperties)\nWhen the selected object has type 'text', show:\n1. **Text content** — textarea input bound to obj.text\n2. **Font family** — dropdown/select populated from fontService.getAvailableFonts(), bound to obj.fontFamily\n3. **Font size** — number input (min 8, max 200, step 1), bound to obj.fontSize\n4. **Letter spacing** — number input (min -5, max 20, step 0.5), bound to obj.letterSpacing\n5. **Line height** — number input (min 0.5, max 3, step 0.1), bound to obj.lineHeight\n6. **Fill color** — color input (reuse existing pattern from hasFill), bound to obj.fill\n7. **Stroke color + weight** — reuse existing stroke controls\n8. **Convert to Paths button** — calls fontService.textToPathData(), then replaces the text object with a new path object (type 'image' with SVG data URL, or a new 'path' type if simpler)\n\n## Convert to Paths Implementation\n- Show confirmation dialog (window.confirm) since this is destructive\n- Call `textToPathData(obj.text, obj.fontFamily, obj.fontSize, obj.letterSpacing)` from fontService\n- Create SVG string from returned path data: ``\n- Convert SVG to Blob URL, create ImageObject replacing the TextObject at same x,y position\n- Use onUpdate to remove old text object and add new image object (or dispatch through a callback prop)\n\n## Integration Notes\n- fontService.ts from T01 provides loadFont(), getAvailableFonts(), textToPathData()\n- The text property controls should only show when object.type === 'text'\n- Existing stroke/fill/opacity/rotation controls still show for text objects\n- ShapeProperties receives onUpdate callback from DesignCanvas — convert-to-paths needs onUpdate + onAddObject + onRemoveObject, so ShapeProperties props may need extending, or the convert action can be handled via a new callback prop\n- DesignCanvas.tsx needs to pass the additional callback(s) to ShapeProperties\n - Estimate: 1h\n - Files: app/src/components/canvas/ShapeProperties.tsx, app/src/views/DesignCanvas.tsx\n - Verify: cd app && npx tsc --noEmit && npx vitest run

tests**\n\n## What Happened\n\nInstalled opentype.js v1.3.4 as a production dependency. Downloaded three OFL-licensed Google Fonts (Roboto, Open Sans, Lato) as .ttf files into `app/public/fonts/` — Roboto and Open Sans are variable font files, Lato is a static weight. Verified all three parse correctly with opentype.js and produce valid glyph path data.\n\nCreated `app/src/utils/fontService.ts` with the following API surface:\n- `getAvailableFonts()` — returns the registry of bundled fonts (family name + filename)\n- `loadFont(url)` — fetches a .ttf by URL, parses via opentype.js, caches the result, deduplicates concurrent loads\n- `loadFontByFamily(family)` — resolves a family name (case-insensitive) to a bundled font URL and loads it; falls back to first bundled font for unknown families\n- `textToPathData(text, family, fontSize, letterSpacing)` — converts text to SVG path `d` attribute data with manual per-character glyph positioning for letter spacing support, Y-axis coordinate flip for canvas-compatible output\n- `clearFontCache()` / `isFontCached(url)` — cache management for testing\n\nAdded `@font-face` declarations for all three fonts in `App.css` with `font-display: swap` so Konva Text nodes render with the matching visual typeface.\n\nWrote 24 unit tests in `fontService.test.ts` covering: available fonts registry, font loading + caching + deduplication + error handling, family name resolution, text-to-path conversion (path format validation, dimension scaling, letter spacing arithmetic, coordinate system verification, edge cases for empty/space-only strings, cross-font consistency).\n\n## Verification\n\nRan the exact verification command from the task plan:\n\n```\ncd app && npx vitest run src/utils/__tests__/fontService.test.ts --reporter=verbose && npx tsc --noEmit && ls public/fonts/*.ttf | wc -l\n```\n\n- All 24 tests pass (1.05s total)\n- TypeScript compiles with zero errors under strict mode with verbatimModuleSyntax\n- 3 font files confirmed in public/fonts/\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `npx vitest run src/utils/__tests__/fontService.test.ts --reporter=verbose` | 0 | ✅ pass | 1.05s |\n| 2 | `npx tsc --noEmit` | 0 | ✅ pass | 2.2s |\n| 3 | `ls public/fonts/*.ttf \\| wc -l` (expected ≥3) | 0 | ✅ pass | <1s |\n\n## Diagnostics\n\nNo issues encountered. Variable font files (.ttf) work correctly with opentype.js — the standard TrueType magic bytes are present and glyph extraction produces valid SVG path data for all three fonts.\n","path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/tasks/T01-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1435,"cacheRead":77542,"cacheWrite":543,"totalTokens":79521,"cost":{"input":0.000005,"output":0.035875000000000004,"cacheRead":0.038771,"cacheWrite":0.00339375,"total":0.07804475}},"stopReason":"toolUse","timestamp":1774504319328}} +{"type":"message","id":"51c2d835","parentId":"fec62a60","timestamp":"2026-03-26T05:52:30.134Z","message":{"role":"toolResult","toolCallId":"toolu_01VFvMq7yZM4DpbqyzZPdUMd","toolName":"write","content":[{"type":"text","text":"Successfully wrote 4471 bytes to /home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/tasks/T01-SUMMARY.md"}],"isError":false,"timestamp":1774504350132}} +{"type":"message","id":"04b82335","parentId":"51c2d835","timestamp":"2026-03-26T05:52:47.241Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_01HfdbqhcnV6FLXPTKVz2dmg","name":"gsd_task_complete","arguments":{"blockerDiscovered":false,"deviations":"None.

Fix these issues before completing the task.\n\n## Working Directory\n\nYour working directory is `/home/aux/development/xpltdco/kerf-engine`. All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/S03-PLAN.md`\n- Task plan source: `.gsd/milestones/M002/slices/S03/tasks/T02-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M002/slices/S03/tasks/T01-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/tasks/T02-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/tasks/T02-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T02 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M002/slices/S03/S03-PLAN.md`\n**Goal:** Add text objects to the design canvas with font loading from bundled fonts, property editing (font family, size, letter spacing, line height), and text-to-path conversion using opentype.js.\n**Demo:** After this: Add text objects, select fonts from picker, change size/spacing, convert text to paths — paths match original glyphs\n\n## Verification Failures\n\n### ❌ `npx tsc --noEmit` (exit code 1)\n```stderr\n\n```\n\n---\n\nYou are executing GSD auto-mode.\n\n## UNIT: Execute Task T02 (\"Add TextObject type and wire text tool into canvas rendering\") — Slice S03 (\"Text System + Font Loading\"), Milestone M002\n\n## Resume State\n- No continue file present.

Created app/src/utils/fontService.ts with loadFont, loadFontByFamily, textToPathData, getAvailableFonts, clearFontCache, and isFontCached exports. The service fetches .ttf files, parses them with opentype.js, caches parsed Font objects with in-flight deduplication, and converts text to SVG path data with manual per-character glyph positioning for letter spacing and Y-axis coordinate flip for canvas compatibility. Added @font-face declarations in App.css for all three fonts.

Added it to the CanvasObject discriminated union. Then wired the text type through all six canvas component files:\n\n1. **KonvaStage.tsx**: Added 'text' to CanvasTool union, imported `Text as KonvaText` from react-konva, added `case 'text'` in renderObject switch (renders KonvaText with all text props), added text tool creation in handleStageMouseDown (defaults: 'Text', Roboto, 24px, 0 letter spacing, 1.2 line height, black fill, 200px width), added text cases in getObjWidth/getObjHeight, and text-specific transform handling (scales width only, keeps fontSize unchanged).\n\n2. **CanvasToolbar.tsx**: Added `{ tool: 'text', label: 'Text', icon: 'T' }` to TOOLS array.\n\n3. **ObjectPanel.tsx**: Added `text: 'T'` to TYPE_ICONS record.\n\n4. **ShapeProperties.tsx**: Added `case 'text'` to both getWidth and getHeight helpers.

Fix these issues before completing the task.\n\n## Working Directory\n\nYour working directory is `/home/aux/development/xpltdco/kerf-engine`. All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/S03-PLAN.md`\n- Task plan source: `.gsd/milestones/M002/slices/S03/tasks/T03-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M002/slices/S03/tasks/T01-SUMMARY.md`\n- `.gsd/milestones/M002/slices/S03/tasks/T02-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/tasks/T03-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/tasks/T03-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T03 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M002/slices/S03/S03-PLAN.md`\n**Goal:** Add text objects to the design canvas with font loading from bundled fonts, property editing (font family, size, letter spacing, line height), and text-to-path conversion using opentype.js.\n**Demo:** After this: Add text objects, select fonts from picker, change size/spacing, convert text to paths — paths match original glyphs\n\n## Verification Failures\n\n### ❌ `npx tsc --noEmit` (exit code 1)\n```stderr\n\n```\n\n### ❌ `npx vitest run --reporter=verbose` (exit code 1)\n```stderr\n\n\u001b[31m⎯⎯⎯⎯⎯⎯\u001b[39m\u001b[1m\u001b[41m Failed Tests 34 \u001b[49m\u001b[22m\u001b[31m⎯⎯⎯⎯⎯⎯⎯\u001b[39m\n\n\u001b[41m\u001b[1m FAIL \u001b[22m\u001b[49m app/src/components/__tests__/OutputInfoBar.test.tsx\u001b[2m > \u001b[22mOutputInfoBar\u001b[2m > \u001b[22mshows placeholder when metadata is null\n\u001b[31m\u001b[1mReferenceError\u001b[22m: document is not defined\u001b[39m\n\u001b[90m \u001b[2m❯\u001b[22m render app/node_modules/@testing-library/react/dist/pure.js:\u001b[2m256:5\u001b[22m\u001b[39m\n\u001b[36m \u001b[2m❯\u001b[22m app/src/components/__tests__/OutputInfoBar.test.tsx:\u001b[2m21:27\u001b[22m\u001b[39m\n \u001b[90m 19|\u001b[39m \u001b[34mdescribe\u001b[39m(\u001b[32m'OutputInfoBar'\u001b[39m\u001b[33m,\u001b[39m () \u001b[33m=>\u001b[39m {\n \u001b[90m 20|\u001b[39m \u001b[34mit\u001b[39m(\u001b[32m'shows placeholder when metadata is null'\u001b[39m\u001b[33m,\u001b[39m () \u001b[33m=>\u001b[39m {\n \u001b[90m 21|\u001b[39m \u001b[35mconst\u001b[39m { container } \u001b[33m=\u001b[39m \u001b[34mrender\u001b[39m(\u001b[33m<\u001b[39m\u001b[33mOutputInfoBar\u001b[39m \u001b[33mmetadata\u001b[39m\u001b[33m=\u001b[39m\u001b[33m{\u001b[39m\u001b[35mnull\u001b[39m\u001b[33m}\u001b[39m \u001b[33m/\u001b[39m\u001b[33m>\u001b[39m)\u001b[33m;\u001b[39m\n \u001b[90m |\u001b[39m \u001b[31m^\u001b[39m\n \u001b[90m 22|\u001b[39m expect(container.querySelector('.output-info-bar--empty')).toBeTru…\n \u001b[90m 23|\u001b[39m \u001b[34mexpect\u001b[39m(screen\u001b[33m.\u001b[39m\u001b[34mgetByText\u001b[39m(\u001b[36m/trace an image/i\u001b[39m))\u001b[33m.\u001b[39m\u001b[34mtoBeInTheDocument\u001b[39m()\u001b[33m;\u001b[39m\n\n\u001b[31m\u001b[2m⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯[1/34]⎯\u001b[22m\u001b[39m\n\n\u001b[41m\u001b[1m FAIL \u001b[22m\u001b[49m app/src/components/__tests__/OutputInfoBar.test.tsx\u001b[2m > \u001b[22mOutputInfoBar\u001b[2m > \u001b[22mrenders stats with green indicators for normal metadata\n\u001b[31m\u001b[1mReferenceError\u001b[22m: document is not defined\u001b[39m\n\u001b[90m \u001b[2m❯\u001b[22m render app/node_modules/@testing-library/react/dist/pure.js:\u001b[2m256:5\u001b[22m\u001b[39m\n\u001b[36m \u001b[2m❯\u001b[22m app/src/components/__tests__/OutputInfoBar.test.tsx:\u001b[2m28:5\u001b[22m\u001b[39m\n \u001b[90m 26|\u001b[39m \u001b[34mit\u001b[39m(\u001b[32m'renders stats with green indicators for normal metadata'\u001b[39m\u001b[33m,\u001b[39m () \u001b[33m=>\u001b[39m {\n \u001b[90m 27|\u001b[39m \u001b[35mconst\u001b[39m meta \u001b[33m=\u001b[39m \u001b[34mmakeMetadata\u001b[39m()\u001b[33m;\u001b[39m\n \u001b[90m 28|\u001b[39m \u001b[34mrender\u001b[39m(\u001b[33m<\u001b[39m\u001b[33mOutputInfoBar\u001b[39m \u001b[33mmetadata\u001b[39m\u001b[33m=\u001b[39m\u001b[33\n…[truncated]\n```\n\n---\n\nYou are executing GSD auto-mode.\n\n## UNIT: Execute Task T03 (\"Build text properties panel and convert-to-paths action in ShapeProperties\") — Slice S03 (\"Text System + Font Loading\"), Milestone M002\n\n## Resume State\n- No continue file present.

23\nestimated_files: 2\nskills_used: []\n---\n\n# T03: Build text properties panel and convert-to-paths action in ShapeProperties\n\nAdd text-specific property controls to ShapeProperties and implement the 'Convert to Paths' action that replaces a TextObject with path-based objects using fontService.textToPathData().\n\n## Text Property Controls (in ShapeProperties)\nWhen the selected object has type 'text', show:\n1. **Text content** — textarea input bound to obj.text\n2. **Font family** — dropdown/select populated from fontService.getAvailableFonts(), bound to obj.fontFamily\n3. **Font size** — number input (min 8, max 200, step 1), bound to obj.fontSize\n4. **Letter spacing** — number input (min -5, max 20, step 0.5), bound to obj.letterSpacing\n5. **Line height** — number input (min 0.5, max 3, step 0.1), bound to obj.lineHeight\n6. **Fill color** — color input (reuse existing pattern from hasFill), bound to obj.fill\n7. **Stroke color + weight** — reuse existing stroke controls\n8. **Convert to Paths button** — calls fontService.textToPathData(), then replaces the text object with a new path object (type 'image' with SVG data URL, or a new 'path' type if simpler)\n\n## Convert to Paths Implementation\n- Show confirmation dialog (window.confirm) since this is destructive\n- Call `textToPathData(obj.text, obj.fontFamily, obj.fontSize, obj.letterSpacing)` from fontService\n- Create SVG string from returned path data: ``\n- Convert SVG to Blob URL, create ImageObject replacing the TextObject at same x,y position\n- Use onUpdate to remove old text object and add new image object (or dispatch through a callback prop)\n\n## Integration Notes\n- fontService.ts from T01 provides loadFont(), getAvailableFonts(), textToPathData()\n- The text property controls should only show when object.type === 'text'\n- Existing stroke/fill/opacity/rotation controls still show for text objects\n- ShapeProperties receives onUpdate callback from DesignCanvas — convert-to-paths needs onUpdate + onAddObject + onRemoveObject, so ShapeProperties props may need extending, or the convert action can be handled via a new callback prop\n- DesignCanvas.tsx needs to pass the additional callback(s) to ShapeProperties\n\n## Inputs\n\n- ``app/src/utils/fontService.ts` — font loading and text-to-path conversion from T01`\n- ``app/src/types/canvas.ts` — TextObject type from T02`\n- ``app/src/components/canvas/ShapeProperties.tsx` — existing property panel to extend with text controls from T02`\n- ``app/src/views/DesignCanvas.tsx` — existing view container that passes props to ShapeProperties`\n\n## Expected Output\n\n- ``app/src/components/canvas/ShapeProperties.tsx` — updated with text property controls (font picker, size, spacing, content) and Convert to Paths button`\n- ``app/src/views/DesignCanvas.tsx` — updated to pass additional callbacks to ShapeProperties for convert-to-paths

implement the 'Convert to Paths' action that replaces a TextObject with path-based objects using fontService.textToPathData().\n\n## Text Property Controls (in ShapeProperties)\nWhen the selected object has type 'text', show:\n1. **Text content** — textarea input bound to obj.text\n2. **Font family** — dropdown/select populated from fontService.getAvailableFonts(), bound to obj.fontFamily\n3. **Font size** — number input (min 8, max 200, step 1), bound to obj.fontSize\n4. **Letter spacing** — number input (min -5, max 20, step 0.5), bound to obj.letterSpacing\n5. **Line height** — number input (min 0.5, max 3, step 0.1), bound to obj.lineHeight\n6. **Fill color** — color input (reuse existing pattern from hasFill), bound to obj.fill\n7. **Stroke color + weight** — reuse existing stroke controls\n8. **Convert to Paths button** — calls fontService.textToPathData(), then replaces the text object with a new path object (type 'image' with SVG data URL, or a new 'path' type if simpler)\n\n## Convert to Paths Implementation\n- Show confirmation dialog (window.confirm) since this is destructive\n- Call `textToPathData(obj.text, obj.fontFamily, obj.fontSize, obj.letterSpacing)` from fontService\n- Create SVG string from returned path data: ``\n- Convert SVG to Blob URL, create ImageObject replacing the TextObject at same x,y position\n- Use onUpdate to remove old text object and add new image object (or dispatch through a callback prop)\n\n## Integration Notes\n- fontService.ts from T01 provides loadFont(), getAvailableFonts(), textToPathData()\n- The text property controls should only show when object.type === 'text'\n- Existing stroke/fill/opacity/rotation controls still show for text objects\n- ShapeProperties receives onUpdate callback from DesignCanvas — convert-to-paths needs onUpdate + onAddObject + onRemoveObject, so ShapeProperties props may need extending, or the convert action can be handled via a new callback prop\n- DesignCanvas.tsx needs to pass the additional callback(s) to ShapeProperties\n\n## Inputs\n\n- ``app/src/utils/fontService.ts` — font loading and text-to-path conversion from T01`\n- ``app/src/types/canvas.ts` — TextObject type from T02`\n- ``app/src/components/canvas/ShapeProperties.tsx` — existing property panel to extend with text controls from T02`\n- ``app/src/views/DesignCanvas.tsx` — existing view container that passes props to ShapeProperties`\n\n## Expected Output\n\n- ``app/src/components/canvas/ShapeProperties.tsx` — updated with text property controls (font picker, size, spacing, content) and Convert to Paths button`\n- ``app/src/views/DesignCanvas.tsx` — updated to pass additional callbacks to ShapeProperties for convert-to-paths action`\n\n## Verification\n\ncd app && npx tsc --noEmit && npx vitest run --reporter=verbose\n"}],"isError":false,"timestamp":1774504554544}}

Downloaded three OFL-licensed Google Fonts (Roboto, Open Sans, Lato) as .ttf files into app/public/fonts/. Created app/src/utils/fontService.ts with loadFont, loadFontByFamily, textToPathData, getAvailableFonts, clearFontCache, and isFontCached exports. The service fetches .ttf files, parses them with opentype.js, caches parsed Font objects with in-flight deduplication, and converts text to SVG path data with manual per-character glyph positioning for letter spacing and Y-axis coordinate flip for canvas compatibility. Added @font-face declarations in App.css for all three fonts. Wrote 24 comprehensive unit tests covering font registry, loading/caching/deduplication/errors, family resolution, and text-to-path conversion with dimension scaling, letter spacing arithmetic, coordinate system validation, and edge cases.\n\n## Verification\n\nRan: cd app && npx vitest run src/utils/__tests__/fontService.test.ts --reporter=verbose && npx tsc --noEmit && ls public/fonts/*.ttf | wc -l.

Added a \"Convert to Paths\" button that calls fontService.textToPathData() to convert the text to SVG path data, wraps it in an SVG string, creates a Blob URL, and replaces the TextObject with an ImageObject at the same position via a new onConvertToPath callback prop. The button shows a window.confirm dialog before proceeding (destructive action) and displays a \"Converting…\" disabled state during the async operation. Updated DesignCanvas to pass the onConvertToPath handler that removes the text object, adds the new image object, and selects it. The ShapePropertiesProps interface was extended with the optional onConvertToPath prop, keeping backwards compatibility for any other consumers. Existing stroke/fill/opacity/rotation controls continue to render for text objects as before.\n\n## Verification\n\nRan `cd app && npx tsc --noEmit` — zero TypeScript errors. Ran `cd app && npx vitest run --reporter=verbose` — all 95 tests pass across 7 test files.\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `cd app && npx tsc --noEmit` | 0 | ✅ pass | 2400ms |\n| 2 | `cd app && npx vitest run --reporter=verbose` | 0 | ✅ pass | 2200ms |\n\n## Diagnostics\n\nConvert-to-paths errors are logged via console.error with the full error object. The converting state is tracked in component state and reflected in the button's disabled/text state.\n\n## Deviations\n\nUsed a single `onConvertToPath(textObjectId, imageObject)` callback instead of separate onAddObject + onRemoveObject callbacks as the task plan suggested. This is simpler and keeps the replacement atomic from the parent's perspective.\n\n## Known Issues\n\nNone.\n\n## Files Created/Modified\n\n- `app/src/components/canvas/ShapeProperties.tsx` — Added text-specific property controls (textarea, font picker, size/spacing/lineHeight inputs), Convert to Paths button with async fontService integration, and onConvertToPath optional callback prop\n- `app/src/views/DesignCanvas.tsx` — Added handleConvertToPath callback that removes old text object, adds new image object, and selects it; passes callback to ShapeProperties; added ImageObject to type imports\n","path":"/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/tasks/T03-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1064,"cacheRead":89360,"cacheWrite":615,"totalTokens":91040,"cost":{"input":0.000005,"output":0.026600000000000002,"cacheRead":0.04468,"cacheWrite":0.0038437500000000004,"total":0.07512875000000001}},"stopReason":"toolUse","timestamp":1774504649935}} +{"type":"message","id":"935e62f5","parentId":"e5ed014a","timestamp":"2026-03-26T05:57:53.660Z","message":{"role":"toolResult","toolCallId":"toolu_01TENJhneN4BCThFPTgN3JXG","toolName":"write","content":[{"type":"text","text":"Successfully wrote 3668 bytes to /home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/tasks/T03-SUMMARY.md"}],"isError":false,"timestamp":1774504673658}} +{"type":"message","id":"86674099","parentId":"935e62f5","timestamp":"2026-03-26T05:58:01.900Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_013ia5mQTs3C2j9CK2BySmQh","name":"gsd_task_complete","arguments":{"blockerDiscovered":false,"deviations":"Used a single onConvertToPath(textObjectId, imageObject) callback instead of separate onAddObject + onRemoveObject callbacks as the task plan suggested — simpler and keeps the replacement atomic.","keyDecisions":["Convert-to-paths uses a single onConvertToPath(textObjectId, imageObject) callback rather than separate onAddObject + onRemoveObject — simpler prop interface, atomic replacement","Convert-to-paths generates an SVG Blob URL with the text path data and creates an ImageObject at the same position — reuses existing image rendering pipeline"],"keyFiles":["app/src/components/canvas/ShapeProperties.tsx","app/src/views/DesignCanvas.tsx"],"knownIssues":"None.","milestoneId":"M002","narrative":"Extended ShapeProperties with text-specific controls that render when the selected object has type 'text': a textarea for text content, a font family dropdown populated from fontService.getAvailableFonts(), numeric inputs for font size (8–200), letter spacing (-5–20), and line height (0.5–3).

You are the closer — verify the assembled work actually delivers the slice goal, then compress everything into a slice summary. After you finish, a **reassess-roadmap agent** reads your slice summary to decide if the remaining roadmap still makes sense. The slice summary is also the primary record of what this slice achieved — future slice researchers and planners read it as a dependency summary when their work builds on yours.\n\nWrite the summary for those downstream readers. What did this slice actually deliver? What patterns did it establish? What should the next slice know?\n\nAll relevant context has been preloaded below — the slice plan, all task summaries, and the milestone roadmap are inlined. Start working immediately without re-reading these files.\n\n## Inlined Context (preloaded — do not re-read these files)\n\n### Milestone Roadmap\nSource: `.gsd/milestones/M002/M002-ROADMAP.md`\n\n# M002: \n\n## Vision\nBuild the React frontend with the Import & Convert view (View 1) and the Design Canvas (View 2). View 1 integrates with the Engine API for vectorization with live preview. View 2 is a Konva.js-powered 2D design environment with artboard shapes, text objects, basic shapes, layers, alignment tools, and undo/redo.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Import & Convert UI (View 1) | medium — debounced preview updates, engine api integration from browser | — | ✅ | Upload a PNG, see live preview with preset selection and slider controls, click 'Use This' to advance to canvas |\n| S02 | Design Canvas Core (View 2) | medium — konva.js setup, selection handles, undo/redo state management | S01 | ✅ | Create artboards in each shape, add/move/resize shapes, multi-select with alignment, undo/redo through history |\n| S03 | Text System + Font Loading | medium — opentype.js integration, font loading from volume, path extraction accuracy | S02 | ⬜ | Add text objects, select fonts from picker, change size/spacing, convert text to paths — paths match original glyphs |\n\n---\n\n### Slice Plan\nSource: `.gsd/milestones/M002/slices/S03/S03-PLAN.md`\n\n# S03: Text System + Font Loading\n\n**Goal:** Add text objects to the design canvas with font loading from bundled fonts, property editing (font family, size, letter spacing, line height), and text-to-path conversion using opentype.js.\n**Demo:** After this: Add text objects, select fonts from picker, change size/spacing, convert text to paths — paths match original glyphs\n\n## Tasks\n- [x] **T01: Built fontService with opentype.js font loading, caching, text-to-path conversion, bundled 3 OFL Google Fonts, and added 24 passing unit tests** — Create the fontService utility that loads .ttf fonts via fetch + opentype.parse(), caches parsed Font objects, and converts text to SVG path data. Bundle 3-5 OFL-licensed Google Fonts as .ttf files in app/public/fonts/. Add @font-face CSS declarations in App.css so Konva Text rendering matches the opentype.js fonts. Install opentype.js dependency. Write comprehensive unit tests for font loading, caching, and text-to-path conversion.\n\nThis is the riskiest piece of the slice — if opentype.js path extraction doesn't produce accurate SVG `d` attributes compatible with Konva's Path component, everything downstream breaks. Testing with real bundled font files proves the integration.\n\n## Key Constraints\n- opentype.js loads fonts from ArrayBuffer — must fetch() font files then call opentype.parse()\n- Path.toPathData() needs consideration of coordinate systems (font Y-up vs canvas Y-down)\n- Letter spacing is NOT built into getPath() — must implement per-character glyph positioning with manual x-advance\n- Font files served from /fonts/ via Vite's public directory\n- @font-face CSS must load before Konva renders Text nodes\n- TypeScript strict mode with verbatimModuleSyntax — use `import type` for type-only imports\n- Tests should mock fetch() to return real font file ArrayBuffers loaded from disk\n - Estimate: 1h\n - Files: app/src/utils/fontService.ts, app/src/utils/__tests__/fontService.test.ts, app/public/fonts/, app/src/App.css, app/package.json\n - Verify: cd app && npx vitest run src/utils/__tests__/fontService.test.ts --reporter=verbose && npx tsc --noEmit && ls public/fonts/*.ttf | wc -l\n- [x] **T02: Added TextObject to CanvasObject union and wired text tool into KonvaStage rendering, CanvasToolbar, ObjectPanel, ShapeProperties, and AlignmentBar with exhaustive switch coverage** — Extend the CanvasObject discriminated union with a TextObject type. Wire text objects into all canvas components: KonvaStage (render via Konva Text + case in getObjWidth/getObjHeight + text tool creation in handleStageMouseDown), CanvasToolbar (add 'text' to CanvasTool union and TOOLS array), ObjectPanel (add 'text' icon to TYPE_ICONS), and DesignCanvas (pass through). This follows the exact pattern established in S02 for adding object types.\n\n## Key Implementation Details\n- TextObject interface: extends BaseCanvasObject with type: 'text', text: string, fontFamily: string, fontSize: number, letterSpacing: number, lineHeight: number, fill: string, stroke: string, strokeWidth: number, width: number (for wrapping)\n- CanvasTool union in KonvaStage.tsx must add 'text' — this is imported by CanvasToolbar\n- KonvaStage renderObject switch: case 'text' renders from react-konva with fontFamily, fontSize, fill, stroke, strokeWidth, width, letterSpacing, lineHeight props\n- KonvaStage handleStageMouseDown switch: case 'text' creates a TextObject with defaults (text: 'Text', fontFamily: 'Roboto', fontSize: 24, letterSpacing: 0, lineHeight: 1.2)\n- KonvaStage getObjWidth for text: use obj.width (wrapping width) or estimate from fontSize * text.length * 0.6\n- KonvaStage getObjHeight for text: obj.fontSize * obj.lineHeight\n- KonvaStage onTransformEnd for text: scale width, keep fontSize unchanged (text wraps to new width)\n- ObjectPanel TYPE_ICONS: text → 'T'\n- ShapeProperties getWidth/getHeight: add case 'text' returning obj.width and obj.fontSize * obj.lineHeight\n- All switch statements must be exhaustive — TypeScript noFallthroughCasesInSwitch enforces this\n- TypeScript strict mode — no unused locals/params, erasableSyntaxOnly, use import type\n - Estimate: 1h\n - Files: app/src/types/canvas.ts, app/src/components/canvas/KonvaStage.tsx, app/src/components/canvas/CanvasToolbar.tsx, app/src/components/canvas/ObjectPanel.tsx, app/src/components/canvas/ShapeProperties.tsx\n - Verify: cd app && npx tsc --noEmit && npx vitest run --reporter=verbose\n- [x] **T03: Added text-specific property controls (content, font family, size, letter spacing, line height) and Convert to Paths button to ShapeProperties, wired through DesignCanvas** — Add text-specific property controls to ShapeProperties and implement the 'Convert to Paths' action that replaces a TextObject with path-based objects using fontService.textToPathData().\n\n## Text Property Controls (in ShapeProperties)\nWhen the selected object has type 'text', show:\n1. **Text content** — textarea input bound to obj.text\n2. **Font family** — dropdown/select populated from fontService.getAvailableFonts(), bound to obj.fontFamily\n3. **Font size** — number input (min 8, max 200, step 1), bound to obj.fontSize\n4. **Letter spacing** — number input (min -5, max 20, step 0.5), bound to obj.letterSpacing\n5. **Line height** — number input (min 0.5, max 3, step 0.1), bound to obj.lineHeight\n6. **Fill color** — color input (reuse existing pattern from hasFill), bound to obj.fill\n7. **Stroke color + weight** — reuse existing stroke controls\n8. **Convert to Paths button** — calls fontService.textToPathData(), then replaces the text object with a new path object (type 'image' with SVG data URL, or a new 'path' type if simpler)\n\n## Convert to Paths Implementation\n- Show confirmation dialog (window.confirm) since this is destructive\n- Call `textToPathData(obj.text, obj.fontFamily, obj.fontSize, obj.letterSpacing)` from fontService\n- Create SVG string from returned path data: ``\n- Convert SVG to Blob URL, create ImageObject replacing the TextObject at same x,y position\n- Use onUpdate to remove old text object and add new image object (or dispatch through a callback prop)\n\n## Integration Notes\n- fontService.ts from T01 provides loadFont(), getAvailableFonts(), textToPathData()\n- The text property controls should only show when object.type === 'text'\n- Existing stroke/fill/opacity/rotation controls still show for text objects\n- ShapeProperties receives onUpdate callback from DesignCanvas — convert-to-paths needs onUpdate + onAddObject + onRemoveObject, so ShapeProperties props may need extending, or the convert action can be handled via a new callback prop\n- DesignCanvas.tsx needs to pass the additional callback(s) to ShapeProperties\n - Estimate: 1h\n - Files: app/src/components/canvas/ShapeProperties.tsx, app/src/views/DesignCanvas.tsx\n - Verify: cd app && npx tsc --noEmit && npx vitest run --reporter=verbose\n\n---\n\n### Project Knowledge\nSource: `.gsd/KNOWLEDGE.md`\n\n# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit. Add entries when you discover something worth remembering.\n\n## Rules\n\n| # | Scope | Rule | Why | Added |\n|---|-------|------|-----|-------|\n\n## Patterns\n\n| # | Pattern | Where | Notes |\n|---|---------|-------|-------|\n| P001 | Test images generated programmatically via numpy | engine/tests/ | No fixture image files checked in. Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n| P003 | PostProcessResult is the universal intermediate representation | engine/pipeline/postprocess.py → engine/output/ | All output generators (DXF, JSON, SVG) consume PostProcessResult. Never generate output directly from raw SVG strings. |\n| P004 | _format_response() for consistent multi-format API responses | engine/api/routes.py | DXF returns binary Response with X-Kerf-Metadata header; SVG/JSON return JSON envelopes. Use _format_response() for both /engine/trace and /engine/simplify. |\n| P005 | Preset-driven pipeline: resolve_params() merges preset → user | engine/presets/loader.py, engine/api/routes.py | Presets define defaults for all pipeline stages. User params override. Mode comes from preset unless user explicitly sets it. |\n| P006 | JSON.stringify for React hook dependency stabilization | app/src/hooks/useDebouncedTrace.ts | Object params in useEffect deps cause infinite loops (new ref each render). Stringify the params object and use the string in the deps array. Avoids requiring callers to useMemo. |\n| P007 | Vite dev proxy for engine API calls | app/vite.config.ts | `/engine/*` requests proxy to `http://localhost:8000`. API client uses relative URLs (`/engine/presets`). No CORS issues in dev because same-origin via proxy. |\n| P008 | CSS modules for views, global App.css for shared component styles | app/src/views/*.module.css, app/src/App.css | View-specific layout in CSS modules avoids conflicts. Shared styles (upload zone, preset cards, buttons) in App.css for cross-component reuse. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them.

Downloaded three OFL-licensed Google Fonts (Roboto, Open Sans, Lato) as .ttf files into app/public/fonts/. Created app/src/utils/fontService.ts with loadFont, loadFontByFamily, textToPathData, getAvailableFonts, clearFontCache, and isFontCached exports. The service fetches .ttf files, parses them with opentype.js, caches parsed Font objects with in-flight deduplication, and converts text to SVG path data with manual per-character glyph positioning for letter spacing and Y-axis coordinate flip for canvas compatibility. Added @font-face declarations in App.css for all three fonts. Wrote 24 comprehensive unit tests covering font registry, loading/caching/deduplication/errors, family resolution, and text-to-path conversion with dimension scaling, letter spacing arithmetic, coordinate system validation, and edge cases.\n\n## Verification\n\nRan: cd app && npx vitest run src/utils/__tests__/fontService.test.ts --reporter=verbose && npx tsc --noEmit && ls public/fonts/*.ttf | wc -l.

A complex slice with 5 tasks across multiple subsystems needs thorough verification and a detailed summary. Scale the work below accordingly.\n\nThen:\n1. Use the **Slice Summary** and **UAT** output templates from the inlined context above\n2. If a `GSD Skill Preferences` block is present in system context, use it and the `` catalog in your system prompt to decide which skills to load and follow for this unit, without relaxing required verification or artifact rules.\n3. Run all slice-level verification checks defined in the slice plan. All must pass before marking the slice done. If any fail, fix them first.\n4. If the slice plan includes observability/diagnostic surfaces, confirm they work. Skip this for simple slices that don't have observability sections.\n5. If this slice produced evidence that a requirement changed status (Active → Validated, Active → Deferred, etc.), call `gsd_save_decision` with scope=\"requirement\", decision=\"{requirement-id}\", choice=\"{new-status}\", rationale=\"{evidence}\". Do NOT write `.gsd/REQUIREMENTS.md` directly — the engine renders it from the database.\n6. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/S03-SUMMARY.md` (compress all task summaries).\n7. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/S03-UAT.md` — a concrete UAT script with real test cases derived from the slice plan and task summaries. Include preconditions, numbered steps with expected outcomes, and edge cases. This must NOT be a placeholder or generic template — tailor every test case to what this slice actually built.\n8. Review task summaries for `key_decisions`. Append any significant decisions to `.gsd/DECISIONS.md` if missing.\n9. Review task summaries for patterns, gotchas, or non-obvious lessons learned. If any would save future agents from repeating investigation or hitting the same issues, append them to `.gsd/KNOWLEDGE.md`. Only add entries that are genuinely useful — don't pad with obvious observations.\n10. Call `gsd_complete_slice` with milestone_id, slice_id, the slice summary, and the UAT result. Do NOT manually mark the roadmap checkbox — the tool writes to the DB and renders the ROADMAP.md projection automatically.\n11. Do not run git commands — the system commits your changes and handles any merge after this unit succeeds.\n12. Update `.gsd/PROJECT.md` if it exists — refresh current state if needed.\n\n**You MUST call `gsd_complete_slice` with the slice summary and UAT content before finishing. The tool persists to both DB and disk and renders `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/S03-SUMMARY.md` and `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/slices/S03/S03-UAT.md` automatically.**\n\nWhen done, say: \"Slice S03 complete.\"","display":false,"id":"01004440","parentId":"5fbb36fd","timestamp":"2026-03-26T05:58:12.329Z"} +{"type":"message","id":"51b3ae31","parentId":"01004440","timestamp":"2026-03-26T05:58:17.358Z","message":{"role":"assistant","content":[{"type":"text","text":"\n\nI'll start by understanding the verification failures and fixing them.

Clean input/output contracts enable this. | No | human |\n| D002 | | architecture | Build order and gating strategy | Build Engine first (M001), then App canvas (M002), then Export+Deploy+Embed (M003). Human checkpoints gate each transition. | Brief explicitly mandates: validate engine output quality before building canvas UI, validate canvas before export/deploy. Engine is the hardest and most valuable piece. | No | human |\n| D003 | | engine | Post-processing replaces regex metadata extraction | postprocess_svg() pipeline replaces old _extract_svg_metadata() regex approach; all SVG paths are parsed into structured PathInfo objects with coordinates, area, island status | Structured path data is needed for DXF/JSON output generation, RDP simplification, and island detection. XML parsing is now necessary since we need actual coordinate data, not just counts. This supersedes D003's regex approach. | No | agent |\n| D004 | | architecture | Engine Docker image build strategy | Multi-stage build: builder stage compiles pypotrace with build-essential/libagg-dev/libpotrace-dev, runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl). Only engine source is copied — no App code. | Multi-stage keeps the runtime image small by excluding build tools. Copying only engine source enforces the Engine/App separation (D001). curl is included for Docker HEALTHCHECK. | Yes | agent |\n| D005 | | architecture | Frontend technology stack for Kerf App | Vite + React + TypeScript with plain CSS modules, Vitest for testing, raw fetch + FormData for engine API calls, no UI framework for V1 | Minimal dependency surface for a tool that needs fast iteration. The engine API uses multipart/form-data which works naturally with native fetch + FormData. CSS modules avoid global style conflicts without adding a framework. Vitest integrates natively with Vite's transform pipeline. No UI library needed — the app has a focused interface with ~8 components. | Yes | agent |\n| D006 | | frontend | React hook params stabilization strategy for useDebouncedTrace | JSON.stringify params in useEffect deps array, single-effect architecture | useCallback-based triggerTrace with object params caused infinite re-render loops because React creates new object references each render.

The text-to-path conversion handles the font-to-canvas coordinate system transformation (Y-axis flip: `ascender * scale - font_y`) and implements manual per-character glyph positioning to support letter spacing (opentype.js's `getPath()` doesn't support it natively). Three OFL-licensed Google Fonts (Roboto, Open Sans, Lato) were bundled as .ttf files in `app/public/fonts/` with corresponding `@font-face` declarations in App.css. 24 unit tests cover the font registry, loading/caching/deduplication/error handling, family resolution, and text-to-path conversion including dimension scaling, letter spacing arithmetic, coordinate system validation, and edge cases.\n\n**T02 — TextObject type and canvas integration.** Added the `TextObject` interface to the `CanvasObject` discriminated union in `canvas.ts` with text-specific fields (text, fontFamily, fontSize, letterSpacing, lineHeight, fill, stroke, strokeWidth, width). Wired the text type through all six canvas component files: KonvaStage (rendering via ``, tool creation, sizing, transform that scales width only), CanvasToolbar (added 'text' to TOOLS array), ObjectPanel (added 'T' icon), ShapeProperties (getWidth/getHeight cases), and AlignmentBar (toBoundingRect case). All switch statements maintain exhaustive coverage under TypeScript strict mode. Text objects default to fill `#000000` and stroke `transparent` for natural text appearance.\n\n**T03 — Text property controls and Convert to Paths.** Extended ShapeProperties with text-specific controls that render when the selected object has type 'text': textarea for content, font family dropdown populated from `fontService.getAvailableFonts()`, and numeric inputs for font size (8–200), letter spacing (-5–20), and line height (0.5–3). Added a \"Convert to Paths\" button that calls `fontService.textToPathData()`, wraps the result in an SVG string, creates a Blob URL, and replaces the TextObject with an ImageObject via a new `onConvertToPath` callback. The conversion shows a confirmation dialog (destructive action) and a \"Converting…\" disabled state during the async operation. DesignCanvas passes the handler that atomically removes the text object and adds the replacement image.","observabilitySurfaces":[],"oneLiner":"Added text objects to the design canvas with fontService (opentype.js-powered font loading, caching, text-to-path conversion), text tool in toolbar, text-specific property controls, and Convert to Paths action — 24 fontService tests + all 95 app tests pass","patternsEstablished":["P009: opentype.js needs dynamic import() and local type declarations","P010: Font Y-axis flip: canvas_y = ascender - font_y * scale","P011: Letter spacing requires manual per-character glyph positioning","P012: Adding new CanvasObject types requires exhaustive switch updates in 6 files"],"provides":["TextObject type in CanvasObject discriminated union","fontService: loadFont, loadFontByFamily, textToPathData, getAvailableFonts, clearFontCache","Text tool in CanvasToolbar","Text property controls in ShapeProperties","Convert to Paths action (text → image via SVG Blob URL)","3 bundled OFL Google Fonts (Roboto, Open Sans, Lato)"],"requirementsAdvanced":[],"requirementsInvalidated":[],"requirementsSurfaced":[],"requirementsValidated":[],"requires":[{"provides":"CanvasObject discriminated union, KonvaStage rendering pipeline, ShapeProperties component, CanvasToolbar, ObjectPanel, AlignmentBar, useCanvasState hook","slice":"S02"}],"sliceId":"S03","sliceTitle":"Text System + Font Loading","uatContent":"# S03: Text System + Font Loading — UAT\n\n**Milestone:** M002\n**Written:** 2026-03-26\n\n## UAT Type\n\n- UAT mode: mixed (artifact-driven for unit tests + live-runtime for interactive text features)\n- Why this mode is sufficient: fontService logic is thoroughly tested (24 unit tests). The canvas integration follows the established pattern from S02 which was already validated. Interactive features (text tool, property controls, convert-to-paths) would need runtime verification in a browser.\n\n## Preconditions\n\n- `cd app && npm install` has been run (opentype.js v1.3.4 installed)\n- Font files present: `app/public/fonts/{Roboto-Regular,OpenSans-Regular,Lato-Regular}.ttf`\n- For interactive testing: `cd app && npm run dev` (Vite dev server on port 5173)\n\n## Smoke Test\n\nRun `cd app && npx tsc --noEmit && npx vitest run --reporter=verbose` — TypeScript compiles cleanly, all 95 tests pass including 24 fontService tests.\n\n## Test Cases\n\n### 1. Font registry returns bundled fonts\n\n1. Import `getAvailableFonts` from `fontService.ts`\n2. Call `getAvailableFonts()`\n3. **Expected:** Returns array of at least 3 entries, each with `family` and `file` properties. Must include Roboto, Open Sans, and Lato.\n\n### 2. Font loading and caching\n\n1. Call `loadFont('/fonts/Roboto-Regular.ttf')`\n2. Verify it resolves with an object that has `charToGlyph` and `unitsPerEm` properties\n3. Call `isFontCached('/fonts/Roboto-Regular.ttf')`\n4. **Expected:** Returns `true` — font is cached after first load. Second `loadFont` call does not trigger another fetch.\n\n### 3. Text-to-path conversion produces valid SVG data\n\n1. Load Roboto font via `loadFontByFamily('Roboto')`\n2. Call `textToPathData('Hello', 'Roboto', 24, 0)`\n3. **Expected:** Returns `{ d: string, width: number, height: number }` where `d` starts with 'M', contains 'Z' closepath commands, and width/height are positive numbers.\n\n### 4. Letter spacing affects path width\n\n1. Call `textToPathData('AB', 'Roboto', 24, 0)` — record width as W0\n2. Call `textToPathData('AB', 'Roboto', 24, 5)` — record width as W1\n3. Call `textToPathData('AB', 'Roboto', 24, -2)` — record width as W2\n4. **Expected:** W1 > W0 > W2 (positive spacing widens, negative narrows)\n\n### 5. Y coordinates are canvas-compatible (positive)\n\n1. Call `textToPathData('Test', 'Roboto', 48, 0)`\n2. Parse all numeric values after Y-position commands in the returned `d` string\n3. **Expected:** All Y coordinates are ≥ 0 (canvas coordinate system, not font Y-up)\n\n### 6. Text tool creates a text object on canvas\n\n1. Open the app in browser, navigate to Design Canvas (View 2)\n2. Click the text tool ('T') in the toolbar\n3. Click on the canvas stage\n4. **Expected:** A text object appears at the click position with default text \"Text\", font family \"Roboto\", font size 24, black fill, transparent stroke.\n\n### 7. Text property controls render for text objects\n\n1. Select a text object on the canvas\n2. Inspect the ShapeProperties panel\n3. **Expected:** Shows textarea for text content, font family dropdown (Roboto, Open Sans, Lato), font size input (8-200), letter spacing input (-5 to 20), line height input (0.5 to 3), fill color picker, and stroke controls.\n\n### 8. Font family change updates text rendering\n\n1. Select a text object\n2. Change font family dropdown from \"Roboto\" to \"Lato\"\n3. **Expected:** Text on canvas re-renders in Lato font. Font family dropdown shows \"Lato\" selected.\n\n### 9. Text property edits persist through undo/redo\n\n1. Select a text object, change font size from 24 to 48\n2. Press Ctrl+Z (undo)\n3. **Expected:** Font size reverts to 24\n4. Press Ctrl+Shift+Z (redo)\n5. **Expected:** Font size returns to 48\n\n### 10. Convert to Paths replaces text with image\n\n1. Select a text object with text \"Hello\" in Roboto\n2. Click \"Convert to Paths\" button in ShapeProperties\n3. Confirmation dialog appears — click OK\n4. **Expected:** Text object is replaced with an image object at the same position. The image renders the text as vector paths (SVG). The object type in ObjectPanel changes from 'T' to the image icon. Text property controls disappear, replaced by standard image controls.\n\n### 11. Convert to Paths — cancel does nothing\n\n1. Select a text object\n2. Click \"Convert to Paths\" button\n3. Confirmation dialog appears — click Cancel\n4. **Expected:** Nothing changes. Text object remains as-is with all its properties.\n\n### 12. Text objects appear in ObjectPanel with correct icon\n\n1. Add a text object, a rectangle, and an image to the canvas\n2. Inspect the ObjectPanel (layers list)\n3. **Expected:** Text object shows 'T' icon, rectangle shows its icon, image shows its icon. All three are listed with correct names.\n\n### 13. Text objects work with alignment tools\n\n1. Add two text objects at different positions\n2. Select both (multi-select)\n3. Click \"Align Left\" in AlignmentBar\n4. **Expected:** Both text objects align to the leftmost x position. Alignment works identically to how it works for shapes.","verification":"TypeScript: `npx tsc --noEmit` — zero errors under strict mode with verbatimModuleSyntax, noUnusedLocals, noUnusedParameters.

Scaffolded the app/ directory as a Vite + React + TypeScript project with a dev proxy forwarding /engine/* requests to localhost:8000. Built typed API client (getPresets, traceImage, simplifyVector) with AbortSignal support and error handling. Established the test infrastructure with Vitest + jsdom + testing-library. 9 tests pass.\n\n**T02 — UI Shell:** Created the two-column ImportConvert layout (left: controls, right: preview). Built FileUpload component with drag-and-drop + file input fallback, thumbnail preview via URL.createObjectURL, and SVG file detection for mode switching. Built PresetSelector that fetches presets from the engine API on mount with AbortController cleanup, renders preset cards with selection highlighting, and auto-selects 'sign' as default. Set up ViewState routing in App.tsx (import → canvas → export).\n\n**T03 — Core Interaction Loop (highest risk):** Created the useDebouncedTrace custom hook — the central piece — which debounces API calls on params/preset/file change, aborts in-flight requests via AbortController, and routes SVG uploads to simplifyVector() instead of traceImage(). Solved infinite re-render loops by stabilizing params via JSON.stringify in the useEffect dependency array. Built ParameterSliders with mode-aware controls (potrace shows epsilon/turdsize/alphamax; vtracer shows epsilon/filter_speckle/corner_threshold). Built SvgPreview with responsive SVG rendering (strips width/height, preserves viewBox), loading spinner, and error states. Wired the complete live re-trace loop in ImportConvert. 7 hook tests pass.\n\n**T04 — Polish & Completion:** Created OutputInfoBar with color-coded stats (green normal, yellow >5000 nodes, red open paths), warnings display, and processing time.

Built the central `useCanvasState` hook using a useReducer + useRef pattern — reducer drives re-renders for current state, ref holds undo/redo history stacks without triggering renders. Select/deselect are excluded from the undo stack (UI-only concern). History is capped at 50 entries. Created artboard shape utilities (shield/pennant SVG paths, dimension presets, unit conversion), 9 pure alignment/distribute functions, and the `ArtboardSetup` modal component. Installed konva, react-konva, and vitest-canvas-mock. 48 new tests passing.\n\n**T02 — Rendering Layer:** Created `KonvaStage` rendering artboard backgrounds (Rect/Circle/Ellipse/Path based on shape config), mapping all canvas objects to Konva primitives with drag/transform handlers, Transformer synced to selected nodes, and rubber-band multi-select rectangle. Built `DesignCanvas` view container with ResizeObserver-driven sizing, artboard setup flow, and SVG import (Blob URL → Image element → Konva.Image with auto-scale). Wired into `App.tsx` to receive real svgData/traceMetadata props from View 1.\n\n**T03 — Panel System:** Built four panel components: `ObjectPanel` (layer list in reverse z-order with drag reorder, visibility/lock toggles, rename), `AlignmentBar` (6 alignment + 2 distribute + center-on-artboard), `CanvasToolbar` (tool switcher, undo/redo, grid toggle, zoom controls), and `ShapeProperties` (stroke/fill/dimensions/line-style editing with discriminated union narrowing). All wired to useCanvasState in DesignCanvas.\n\n**T04 — Shortcuts & Integration:** Added window-level keyboard shortcuts (Ctrl+Z undo, Ctrl+Shift+Z redo, Delete/Backspace remove, Escape deselect, Ctrl+A select all) with activeElement guard to skip input fields. Verified full integration: View 1 → Use This → Artboard Setup → Canvas with imported SVG. All 71 tests pass, zero TypeScript errors.\n\n## Verification\n\nRan `cd app && npx vitest run --reporter=verbose` — 71 tests pass across 6 test files, 0 failures (exit 0). Ran `cd app && npx tsc --noEmit` — zero type errors under strict mode with noUnusedLocals/noUnusedParameters (exit 0).\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nUsed vitest-canvas-mock instead of jest-canvas-mock (plan specified jest-canvas-mock but it crashes in Vitest because it internally calls jest.fn()). This was identified in T01 and recorded as L010 in KNOWLEDGE.md.\n\n## Known Limitations\n\nCanvas components (KonvaStage, DesignCanvas panels) do not have dedicated unit tests — they were verified via TypeScript compilation and manual integration. Konva rendering in jsdom is limited since canvas operations are mocked. Drag-to-reorder in ObjectPanel uses simple index swapping, not full drag-and-drop library.\n\n## Follow-ups\n\nS03 will add 'text' type to the CanvasObject discriminated union and integrate opentype.js for font loading and text-to-path conversion. ShapeProperties panel will need a text-specific section. The canvas object type system (D008) was designed to accommodate this extension.\n\n## Files Created/Modified\n\n- `app/src/types/canvas.ts` — New — discriminated union type system for canvas objects (rect, circle, ellipse, line, image), ArtboardConfig, CanvasState, and CanvasAction types\n- `app/src/hooks/useCanvasState.ts` — New — central state management hook with useReducer+useRef for CRUD, selection, undo/redo, reorder, visibility/lock\n- `app/src/hooks/__tests__/useCanvasState.test.ts` — New — 20 tests covering all useCanvasState operations including undo/redo edge cases\n- `app/src/utils/artboardShapes.ts` — New — artboard shape presets, shield/pennant SVG path generators, toPx/fromPx unit conversion, artboardClipPath\n- `app/src/utils/__tests__/artboardShapes.test.ts` — New — 15 tests for artboard presets, path generation, unit conversion, clip paths\n- `app/src/utils/alignment.ts` — New — 9 pure alignment/distribute/center functions for canvas objects\n- `app/src/utils/__tests__/alignment.test.ts` — New — 13 tests for alignment, distribution, and center-on-artboard\n- `app/src/components/canvas/ArtboardSetup.tsx` — New — modal for artboard shape/size/unit selection on entering canvas view\n- `app/src/components/canvas/KonvaStage.tsx` — New — Konva Stage+Layer rendering artboard, all object types, Transformer, rubber-band selection\n- `app/src/components/canvas/ObjectPanel.tsx` — New — layer management panel with z-order list, reorder, visibility/lock toggles, rename\n- `app/src/components/canvas/AlignmentBar.tsx` — New — alignment and distribution toolbar consuming alignment utils\n- `app/src/components/canvas/CanvasToolbar.tsx` — New — tool switcher, undo/redo, grid toggle, zoom controls\n- `app/src/components/canvas/ShapeProperties.tsx` — New — property editor for selected shape (stroke, fill, dimensions, line style, opacity)\n- `app/src/views/DesignCanvas.tsx` — New — View 2 container wiring KonvaStage + all panels to useCanvasState, SVG import, keyboard shortcuts\n- `app/src/views/DesignCanvas.module.css` — New — CSS module for DesignCanvas layout\n- `app/src/App.tsx` — Modified — wired DesignCanvas with svgData/traceMetadata props, removed underscore prefixes\n- `app/src/App.css` — Modified — added comprehensive canvas UI styles (toolbar, panels, artboard setup, shape properties, alignment bar)\n- `app/src/test-setup.ts` — Modified — added vitest-canvas-mock import for Konva testing\n- `app/package.json` — Modified — added konva, react-konva, vitest-canvas-mock dependencies\n\n---\n\n### S03 Summary\nSource: `.gsd/milestones/M002/slices/S03/S03-SUMMARY.md`\n\n---\nid: S03\nparent: M002\nmilestone: M002\nprovides:\n -

The text-to-path conversion handles the font-to-canvas coordinate system transformation (Y-axis flip: `ascender * scale - font_y`) and implements manual per-character glyph positioning to support letter spacing (opentype.js's `getPath()` doesn't support it natively). Three OFL-licensed Google Fonts (Roboto, Open Sans, Lato) were bundled as .ttf files in `app/public/fonts/` with corresponding `@font-face` declarations in App.css. 24 unit tests cover the font registry, loading/caching/deduplication/error handling, family resolution, and text-to-path conversion including dimension scaling, letter spacing arithmetic, coordinate system validation, and edge cases.\n\n**T02 — TextObject type and canvas integration.** Added the `TextObject` interface to the `CanvasObject` discriminated union in `canvas.ts` with text-specific fields (text, fontFamily, fontSize, letterSpacing, lineHeight, fill, stroke, strokeWidth, width). Wired the text type through all six canvas component files: KonvaStage (rendering via ``, tool creation, sizing, transform that scales width only), CanvasToolbar (added 'text' to TOOLS array), ObjectPanel (added 'T' icon), ShapeProperties (getWidth/getHeight cases), and AlignmentBar (toBoundingRect case). All switch statements maintain exhaustive coverage under TypeScript strict mode. Text objects default to fill `#000000` and stroke `transparent` for natural text appearance.\n\n**T03 — Text property controls and Convert to Paths.** Extended ShapeProperties with text-specific controls that render when the selected object has type 'text': textarea for content, font family dropdown populated from `fontService.getAvailableFonts()`, and numeric inputs for font size (8–200), letter spacing (-5–20), and line height (0.5–3). Added a \"Convert to Paths\" button that calls `fontService.textToPathData()`, wraps the result in an SVG string, creates a Blob URL, and replaces the TextObject with an ImageObject via a new `onConvertToPath` callback. The conversion shows a confirmation dialog (destructive action) and a \"Converting…\" disabled state during the async operation. DesignCanvas passes the handler that atomically removes the text object and adds the replacement image.\n\n## Verification\n\nTypeScript: `npx tsc --noEmit` — zero errors under strict mode with verbatimModuleSyntax, noUnusedLocals, noUnusedParameters. Tests: `npx vitest run --reporter=verbose` — all 95 tests pass across 7 test files (24 fontService tests + 71 existing tests). Font files: 3 .ttf files confirmed in app/public/fonts/.\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nT02 added case 'text' to AlignmentBar.tsx toBoundingRect — not listed in task plan but required for exhaustive switch coverage. T03 used a single onConvertToPath(textObjectId, imageObject) callback instead of separate onAddObject + onRemoveObject as the plan suggested — simpler and keeps the replacement atomic.\n\n## Known Limitations\n\nConvert-to-paths produces an ImageObject with a Blob URL — the SVG path data is embedded in the URL, not stored as a first-class path object type. Multi-line text is supported by Konva's text wrapping (width property) but the text-to-path conversion treats input as a single line. Font loading requires network fetch of .ttf files — no offline/preload strategy beyond browser caching.\n\n## Follow-ups\n\nNone.\n\n## Files Created/Modified\n\n- `app/src/utils/fontService.ts` — New — font loading, caching, text-to-path conversion service using opentype.js\n- `app/src/utils/__tests__/fontService.test.ts` — New — 24 unit tests for fontService (registry, loading, caching, path conversion)\n- `app/public/fonts/Roboto-Regular.ttf` — New — bundled OFL-licensed Roboto variable font\n- `app/public/fonts/OpenSans-Regular.ttf` — New — bundled OFL-licensed Open Sans variable font\n- `app/public/fonts/Lato-Regular.ttf` — New — bundled OFL-licensed Lato font\n- `app/src/App.css` — Modified — added @font-face declarations for Roboto, Open Sans, Lato\n- `app/package.json` — Modified — added opentype.js v1.3.4 dependency\n- `app/src/types/canvas.ts` — Modified — added TextObject interface and extended CanvasObject union with 'text' type\n- `app/src/components/canvas/KonvaStage.tsx` — Modified — text rendering, text tool creation, text sizing/transform, 'text' in CanvasTool union\n- `app/src/components/canvas/CanvasToolbar.tsx` — Modified — added text tool to TOOLS array\n- `app/src/components/canvas/ObjectPanel.tsx` — Modified — added 'T' icon for text objects in TYPE_ICONS\n- `app/src/components/canvas/ShapeProperties.tsx` — Modified — text property controls (content, font family, size, letter spacing, line height), Convert to Paths button, getWidth/getHeight cases\n- `app/src/components/canvas/AlignmentBar.tsx` — Modified — added text case to toBoundingRect for exhaustive switch\n- `app/src/views/DesignCanvas.tsx` — Modified — added onConvertToPath handler wiring ShapeProperties to canvas state\n\n---\n\n[...truncated 3 sections]\n\n\n\n## Validation Steps\n\n1. For each **success criterion** in `.gsd/milestones/M002/M002-ROADMAP.md`, check whether slice summaries and UAT results provide evidence that it was met. Record pass/fail per criterion.\n2. For each **slice** in the roadmap, verify its demo/deliverable claim against its summary. Flag any slice whose summary does not substantiate its claimed output.\n3. Check **cross-slice integration points** — do boundary map entries (produces/consumes) align with what was actually built?\n4. Check **requirement coverage** — are all active requirements addressed by at least one slice?\n5. Determine a verdict:\n - `pass` — all criteria met, all slices delivered, no gaps\n - `needs-attention` — minor gaps that do not block completion (document them)\n - `needs-remediation` — material gaps found; remediation slices must be added to the roadmap\n\n## Persist Validation\n\n**Persist validation results through `gsd_validate_milestone`.** Call it with: `milestoneId`, `verdict`, `remediationRound`, `successCriteriaChecklist`, `sliceDeliveryAudit`, `crossSliceIntegration`, `requirementCoverage`, `verdictRationale`, and `remediationPlan` (if verdict is `needs-remediation`). The tool writes the validation to the DB and renders VALIDATION.md to disk.\n\nIf verdict is `needs-remediation`:\n- After calling `gsd_validate_milestone`, use `gsd_reassess_roadmap` to add remediation slices. Pass `milestoneId`, a synthetic `completedSliceId` (e.g. \"VALIDATION\"), `verdict: \"roadmap-adjusted\"`, `assessment` text, and `sliceChanges` with the new slices in the `added` array. The tool persists the changes to the DB and re-renders ROADMAP.md.\n- These remediation slices will be planned and executed before validation re-runs.\n\n**File system safety:** When scanning milestone directories for evidence, use `ls` or `find` to list directory contents first — never pass a directory path (e.g. `tasks/`, `slices/`) directly to the `read` tool. The `read` tool only accepts file paths, not directories.\n\nWhen done, say: \"Milestone M002 validation complete — verdict: .\"","display":false,"id":"0a958fc9","parentId":"26ff359e","timestamp":"2026-03-26T06:00:52.438Z"} +{"type":"message","id":"a8521e97","parentId":"0a958fc9","timestamp":"2026-03-26T06:00:58.125Z","message":{"role":"assistant","content":[{"type":"text","text":"\n\nI'll validate Milestone M002 by checking success criteria, slice deliverables, cross-slice integration, and requirement coverage.

If engine returns warnings: **Expected:** Warnings are displayed in the info bar\n\n### Test 11: Use This Button — Disabled State\n1. Load the page fresh (no file uploaded)\n2. **Expected:** \"Use This\" button is visible but disabled/grayed out\n3. Upload a file but before the trace completes:\n4. **Expected:** Button remains disabled while loading\n\n### Test 12: Use This Button — Advances to Canvas\n1. Upload a file, wait for SVG preview to appear\n2. **Expected:** \"Use This\" button becomes enabled\n3. Click the \"Use This\" button\n4. **Expected:** View transitions from Import & Convert to the Design Canvas placeholder (shows \"View 2: Design Canvas\")\n\n### Test 13: Error Handling — API Failure\n1. Stop the engine server\n2. Upload a file\n3. **Expected:** Preview area shows an error message (not a crash or blank screen)\n4. Restart the engine\n5. Re-upload or change a slider\n6. **Expected:** Preview recovers and shows the vectorized result\n\n### Test 14: AbortController Cleanup\n1. Upload a file and immediately upload a different file before the first trace completes\n2. **Expected:** First request is aborted (visible in devtools Network tab as cancelled), second request completes normally\n3. Only the second file's result is shown in the preview\n\n### Edge Cases\n\n### Test 15: Large File Upload\n1. Upload a large image (>5MB)\n2. **Expected:** Upload completes, thumbnail shown, vectorization runs (may take longer than usual)\n3. No UI freezing during processing\n\n### Test 16: Rapid Preset Switching\n1. Upload a file, then rapidly click through 3-4 different presets\n2. **Expected:** Intermediate requests are aborted, only the final preset's result is displayed\n3. No stale results from earlier presets appear after the final result loads\n"}],"isError":false,"timestamp":1774504862175}} +{"type":"message","id":"301927bc","parentId":"f8c79138","timestamp":"2026-03-26T06:01:02.176Z","message":{"role":"toolResult","toolCallId":"toolu_018BRo3GuqboHBmFShno9miX","toolName":"read","content":[{"type":"text","text":"# S02: Design Canvas Core (View 2) — UAT\n\n**Milestone:** M002\n**Written:** 2026-03-26T05:44:01.052Z\n\n## UAT: Design Canvas Core (View 2)\n\n### Preconditions\n- Engine API running at localhost:8000\n- App dev server running (`cd app && npm run dev`)\n- A raster image (PNG/JPG) available for upload\n\n---\n\n### Test 1: View 1 → View 2 Transition\n1.

The canvas integration follows the established pattern from S02 which was already validated. Interactive features (text tool, property controls, convert-to-paths) would need runtime verification in a browser.\n\n## Preconditions\n\n- `cd app && npm install` has been run (opentype.js v1.3.4 installed)\n- Font files present: `app/public/fonts/{Roboto-Regular,OpenSans-Regular,Lato-Regular}.ttf`\n- For interactive testing: `cd app && npm run dev` (Vite dev server on port 5173)\n\n## Smoke Test\n\nRun `cd app && npx tsc --noEmit && npx vitest run --reporter=verbose` — TypeScript compiles cleanly, all 95 tests pass including 24 fontService tests.\n\n## Test Cases\n\n### 1. Font registry returns bundled fonts\n\n1. Import `getAvailableFonts` from `fontService.ts`\n2. Call `getAvailableFonts()`\n3. **Expected:** Returns array of at least 3 entries, each with `family` and `file` properties. Must include Roboto, Open Sans, and Lato.\n\n### 2. Font loading and caching\n\n1. Call `loadFont('/fonts/Roboto-Regular.ttf')`\n2. Verify it resolves with an object that has `charToGlyph` and `unitsPerEm` properties\n3. Call `isFontCached('/fonts/Roboto-Regular.ttf')`\n4. **Expected:** Returns `true` — font is cached after first load. Second `loadFont` call does not trigger another fetch.\n\n### 3. Text-to-path conversion produces valid SVG data\n\n1. Load Roboto font via `loadFontByFamily('Roboto')`\n2. Call `textToPathData('Hello', 'Roboto', 24, 0)`\n3. **Expected:** Returns `{ d: string, width: number, height: number }` where `d` starts with 'M', contains 'Z' closepath commands, and width/height are positive numbers.\n\n### 4. Letter spacing affects path width\n\n1. Call `textToPathData('AB', 'Roboto', 24, 0)` — record width as W0\n2. Call `textToPathData('AB', 'Roboto', 24, 5)` — record width as W1\n3. Call `textToPathData('AB', 'Roboto', 24, -2)` — record width as W2\n4. **Expected:** W1 > W0 > W2 (positive spacing widens, negative narrows)\n\n### 5. Y coordinates are canvas-compatible (positive)\n\n1. Call `textToPathData('Test', 'Roboto', 48, 0)`\n2. Parse all numeric values after Y-position commands in the returned `d` string\n3. **Expected:** All Y coordinates are ≥ 0 (canvas coordinate system, not font Y-up)\n\n### 6. Text tool creates a text object on canvas\n\n1. Open the app in browser, navigate to Design Canvas (View 2)\n2. Click the text tool ('T') in the toolbar\n3. Click on the canvas stage\n4. **Expected:** A text object appears at the click position with default text \"Text\", font family \"Roboto\", font size 24, black fill, transparent stroke.\n\n### 7. Text property controls render for text objects\n\n1. Select a text object on the canvas\n2. Inspect the ShapeProperties panel\n3. **Expected:** Shows textarea for text content, font family dropdown (Roboto, Open Sans, Lato), font size input (8-200), letter spacing input (-5 to 20), line height input (0.5 to 3), fill color picker, and stroke controls.\n\n### 8. Font family change updates text rendering\n\n1. Select a text object\n2. Change font family dropdown from \"Roboto\" to \"Lato\"\n3. **Expected:** Text on canvas re-renders in Lato font. Font family dropdown shows \"Lato\" selected.\n\n### 9. Text property edits persist through undo/redo\n\n1. Select a text object, change font size from 24 to 48\n2. Press Ctrl+Z (undo)\n3. **Expected:** Font size reverts to 24\n4. Press Ctrl+Shift+Z (redo)\n5. **Expected:** Font size returns to 48\n\n### 10. Convert to Paths replaces text with image\n\n1. Select a text object with text \"Hello\" in Roboto\n2. Click \"Convert to Paths\" button in ShapeProperties\n3. Confirmation dialog appears — click OK\n4. **Expected:** Text object is replaced with an image object at the same position. The image renders the text as vector paths (SVG). The object type in ObjectPanel changes from 'T' to the image icon. Text property controls disappear, replaced by standard image controls.\n\n### 11. Convert to Paths — cancel does nothing\n\n1. Select a text object\n2. Click \"Convert to Paths\" button\n3. Confirmation dialog appears — click Cancel\n4. **Expected:** Nothing changes. Text object remains as-is with all its properties.\n\n### 12. Text objects appear in ObjectPanel with correct icon\n\n1. Add a text object, a rectangle, and an image to the canvas\n2. Inspect the ObjectPanel (layers list)\n3. **Expected:** Text object shows 'T' icon, rectangle shows its icon, image shows its icon. All three are listed with correct names.\n\n### 13. Text objects work with alignment tools\n\n1. Add two text objects at different positions\n2. Select both (multi-select)\n3.

Add `CORSMiddleware` to `engine/main.py` — import from `fastapi.middleware.cors`, allow all origins for dev (restrict in production later). Place it before the router include.\n2. Scaffold `app/` using `npm create vite@latest app -- --template react-ts`. Run `cd app && npm install`.\n3. Configure `app/vite.config.ts` with a dev proxy: requests to `/engine/*` forward to `http://localhost:8000`.\n4. Create `app/src/types/engine.ts` with TypeScript interfaces:\n - `PresetConfig` — matches the JSON structure in `engine/presets/*.json` (name, description, preprocessing, vectorization, postprocessing sections)\n - `TraceResponse` — `{ output: string, format: string, metadata: TraceMetadata }`\n - `TraceMetadata` — `{ format: string, path_count: number, node_count_total: number, open_paths: number, island_count: number, warnings: string[], processing_ms: number }`\n - `PresetsResponse` — `{ presets: Record }`\n5. Create `app/src/api/engine.ts` with typed functions:\n - `getPresets(): Promise` — calls `GET /engine/presets`\n - `traceImage(file: File, preset: string, params: Record, signal?: AbortSignal): Promise` — builds `FormData` with file, mode, output_format='svg', preset, and params (JSON.stringify), calls `POST /engine/trace`\n - `simplifyVector(file: File, epsilon: number, signal?: AbortSignal): Promise` — calls `POST /engine/simplify`\n6. Remove Vite boilerplate: delete `app/src/App.css`, the counter component content from `App.tsx`, and the Vite/React logos.\n7. Add Vitest as dev dependency: `cd app && npm install -D vitest @testing-library/react @testing-library/jest-dom jsdom`. Configure in `vite.config.ts` with `test: { environment: 'jsdom', globals: true }`.\n8. Write `app/src/api/__tests__/engine.test.ts` — unit tests for the API client using `vi.fn()` to mock fetch. Test that `traceImage()` builds correct FormData, `getPresets()` calls the right URL, and AbortSignal is passed through.\n - Estimate: 45m\n - Files: engine/main.py, app/package.json, app/vite.config.ts, app/tsconfig.json, app/src/types/engine.ts, app/src/api/engine.ts, app/src/api/__tests__/engine.test.ts, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20\n- [x] **T02: Built app shell with ViewState routing, drag-and-drop FileUpload with thumbnail preview, PresetSelector fetching from engine API, and two-column ImportConvert layout** — Build the first user-facing components: the app shell with view-state routing (Import → Canvas → Export), a drag-and-drop file upload zone, and a preset selector that fetches presets from the engine and populates parameter defaults.\n\n## Steps\n\n1. Create `app/src/views/ImportConvert.tsx` — the main View 1 container. Layout: left panel (upload + controls) and right panel (preview area, placeholder for now). Use CSS modules or a single `app/src/views/ImportConvert.module.css`.\n2. Update `app/src/App.tsx` with view-state routing using React useState:\n - `type ViewState = 'import' | 'canvas' | 'export'`\n - Render `ImportConvert` when state is 'import', placeholder `
View 2: Design Canvas
` for 'canvas', placeholder for 'export'\n - Pass a callback `onUseThis(svgOutput: string, metadata: TraceMetadata)` that transitions to 'canvas'\n3. Create `app/src/components/FileUpload.tsx`:\n - Drag-and-drop zone with `onDragOver`/`onDrop` handlers + hidden file `` fallback\n - Accept: `.png,.jpg,.jpeg,.bmp,.tiff,.webp,.svg` via accept attribute\n - On file selection: store `File` in parent state, show filename + file size, render thumbnail via `URL.createObjectURL()`\n - Detect SVG uploads (check file type or extension) and surface this to parent for mode switching\n4. Create `app/src/components/PresetSelector.tsx`:\n - On mount: call `getPresets()` from `app/src/api/engine.ts`\n - Render preset cards — each shows name and description from the preset config\n - Clicking a card selects it (visual highlight) and calls `onPresetSelect(presetName, presetConfig)` callback\n - Default selection: 'sign' preset\n5. Create `app/src/App.css` (or global styles) with minimal layout: flexbox two-column layout for View 1, card styles for presets, drop zone styling with dashed border + hover state.\n6. Wire components together in `ImportConvert.tsx`: FileUpload at top, PresetSelector below it, both in the left panel. Store selected file and preset in local state.\n - Estimate: 1h\n - Files: app/src/App.tsx, app/src/App.css, app/src/views/ImportConvert.tsx, app/src/views/ImportConvert.module.css, app/src/components/FileUpload.tsx, app/src/components/PresetSelector.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [x] **T03: Built useDebouncedTrace hook with AbortController cancellation, ParameterSliders with mode-aware controls, SvgPreview with responsive rendering, and wired the complete live re-trace loop in ImportConvert** — Build the core interaction loop: parameter sliders derived from preset defaults, debounced re-trace on any change, AbortController-based request cancellation, and inline SVG rendering. This is the highest-risk piece of the slice.\n\n## Steps\n\n1. Create `app/src/hooks/useDebouncedTrace.ts` — a custom hook that encapsulates the debounce + abort logic:\n - Accepts: `file: File | null`, `preset: string`, `params: Record`, `debounceMs: number` (default 300)\n - Maintains an `AbortController` ref. On each trigger: clear previous timeout, abort previous request, set new timeout\n - After debounce: call `traceImage(file, preset, params, signal)` from the API client\n - Returns: `{ svgOutput: string | null, metadata: TraceMetadata | null, isLoading: boolean, error: string | null }`\n - On unmount: abort any in-flight request and clear timeout\n - For SVG file uploads: call `simplifyVector()` instead of `traceImage()`\n2. Create `app/src/components/ParameterSliders.tsx`:\n - Accepts current preset config and an `onChange(params)` callback\n - Renders labeled range inputs for key parameters:\n - **Detail Level** (epsilon): range 0.5–10, step 0.5, from postprocessing.epsilon\n - **Noise Filter** (filter_speckle/turdsize): range 0–50, step 1, from vectorization params\n - **Smooth Curves** (alphamax): range 0–1.334, step 0.1, from vectorization.potrace.alphamax\n - **Corner Threshold** (corner_threshold): range 0–180, step 1, from vectorization.vtracer.corner_threshold (only shown for vtracer mode)\n - Show/hide sliders based on vectorization mode (potrace vs vtracer) from preset\n - Each slider change calls `onChange` with the full current params object\n - Show current numeric value next to each slider\n3. Create `app/src/components/SvgPreview.tsx`:\n - Accepts `svgOutput: string | null`, `isLoading: boolean`, `error: string | null`\n - When loading: show a spinner/overlay\n - When error: show error message with retry suggestion\n - When SVG available: render via `dangerouslySetInnerHTML` inside a container div\n - Strip `width` and `height` attributes from the SVG string (keep viewBox) for responsive scaling\n - Apply CSS: `width: 100%; height: auto; max-height: 70vh; object-fit: contain` on the container\n4. Wire everything in `ImportConvert.tsx`:\n - Track `currentParams` state, initialized from selected preset defaults\n - When preset changes: reset params to new preset defaults, trigger re-trace\n - When slider changes: update params, trigger re-trace via the debounced hook\n - When file changes: trigger immediate trace (no debounce for initial upload)\n - Pass svgOutput/isLoading/error to SvgPreview\n5. Write `app/src/hooks/__tests__/useDebouncedTrace.test.ts` — test the hook with mocked fetch:\n - Verify debounce behavior (multiple rapid calls → only last fires)\n - Verify abort: mock AbortController, confirm signal is passed and previous request aborted\n - Verify SVG mode detection routes to simplifyVector\n - Estimate: 1h30m\n - Files: app/src/hooks/useDebouncedTrace.ts, app/src/components/ParameterSliders.tsx, app/src/components/SvgPreview.tsx, app/src/views/ImportConvert.tsx, app/src/hooks/__tests__/useDebouncedTrace.test.ts\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n- [x] **T04: Created OutputInfoBar with color-coded stats, wired Use This button with disabled state, added 7 component tests — 23/23 tests pass, zero TS errors** — Complete the slice by adding the output info bar with color-coded stats, the 'Use This' button that advances to View 2, error/empty states, and a full-stack integration verification.\n\n## Steps\n\n1. Create `app/src/components/OutputInfoBar.tsx`:\n - Accepts `metadata: TraceMetadata | null`\n - When metadata is null: render nothing or a muted placeholder\n - Render stats: Path Count, Total Nodes, Open Paths, Processing Time\n - Color coding: green for normal values, yellow when node_count_total > 5000, red when open_paths > 0\n - Show warnings from metadata.warnings array if any\n2. Add 'Use This' button to `ImportConvert.tsx`:\n - Disabled when no SVG output is available\n - On click: call `onUseThis(svgOutput, metadata)` prop, which App.tsx uses to transition view state to 'canvas'\n - Pass the SVG string forward (stored in App.tsx state for S02 to consume)\n3. Add empty/error states throughout:\n - No file selected: show upload prompt in preview area\n - API error: show error message in preview area with status code\n - Loading: show spinner overlay on preview\n4. Write `app/src/components/__tests__/OutputInfoBar.test.tsx` — test color coding logic:\n - Normal metadata → green indicators\n - High node count → yellow indicator\n - Open paths > 0 → red indicator\n - Null metadata → no crash, placeholder shown\n5. Final verification: ensure `npx tsc --noEmit` passes with zero errors, `npx vitest run` passes all tests, and all components are wired together end-to-end.\n - Estimate: 45m\n - Files: app/src/components/OutputInfoBar.tsx, app/src/components/__tests__/OutputInfoBar.test.tsx, app/src/views/ImportConvert.tsx, app/src/App.tsx\n - Verify: cd app && npx vitest run --reporter=verbose 2>&1 | tail -20 && npx tsc --noEmit 2>&1 | tail -10\n"}],"isError":false,"timestamp":1774504893473}} +{"type":"message","id":"b2243e32","parentId":"676cc7a4","timestamp":"2026-03-26T06:01:33.476Z","message":{"role":"toolResult","toolCallId":"toolu_01X62VxKrnyXUbsXhRsq8qLX","toolName":"read","content":[{"type":"text","text":"# S02: Design Canvas Core (View 2)\n\n**Goal:** Build the Konva.js-powered 2D design canvas (View 2) with artboard shapes, basic shapes (rect/circle/ellipse/line), imported SVG rendering, selection handles, multi-select, object/layer panel with reorder, alignment tools, and undo/redo.\n**Demo:** After this: Create artboards in each shape, add/move/resize shapes, multi-select with alignment, undo/redo through history\n\n## Tasks\n- [x] **T01: Built canvas type system, useCanvasState hook with undo/redo, artboard shapes, alignment utils, ArtboardSetup component, and 48 new tests passing** — Establish the foundation that every other task depends on: canvas type definitions (discriminated union for canvas objects, artboard config, canvas state), the central useCanvasState hook with full CRUD + selection + undo/redo, artboard shape utilities, the ArtboardSetup component, and canvas mock setup for Vitest. This is the riskiest piece — the state model shape affects every downstream component.\n\nThe useCanvasState hook is a useReducer + useRef pattern: current state in a reducer (triggers re-renders), history stack in a useRef (avoids re-renders on history push). Every mutation dispatches through the reducer which also pushes a history snapshot. Undo/redo pops from history.\n\nThe ArtboardSetup component renders a modal overlay on first entering the canvas view with shape picker (rect, square, circle, oval, shield, pennant, custom), width/height number inputs, and inches/mm units toggle.

Layout: top toolbar area, left canvas with KonvaStage, right panel area (wired in T03). Receives svgData and traceMetadata props from App.tsx.\n- Wire DesignCanvas into App.tsx replacing the placeholder div.

Bundle 3-5 OFL-licensed Google Fonts as .ttf files in app/public/fonts/. Add @font-face CSS declarations in App.css so Konva Text rendering matches the opentype.js fonts. Install opentype.js dependency. Write comprehensive unit tests for font loading, caching, and text-to-path conversion.\n\nThis is the riskiest piece of the slice — if opentype.js path extraction doesn't produce accurate SVG `d` attributes compatible with Konva's Path component, everything downstream breaks. Testing with real bundled font files proves the integration.\n\n## Key Constraints\n- opentype.js loads fonts from ArrayBuffer — must fetch() font files then call opentype.parse()\n- Path.toPathData() needs consideration of coordinate systems (font Y-up vs canvas Y-down)\n- Letter spacing is NOT built into getPath() — must implement per-character glyph positioning with manual x-advance\n- Font files served from /fonts/ via Vite's public directory\n- @font-face CSS must load before Konva renders Text nodes\n- TypeScript strict mode with verbatimModuleSyntax — use `import type` for type-only imports\n- Tests should mock fetch() to return real font file ArrayBuffers loaded from disk\n - Estimate: 1h\n - Files: app/src/utils/fontService.ts, app/src/utils/__tests__/fontService.test.ts, app/public/fonts/, app/src/App.css, app/package.json\n - Verify: cd app && npx vitest run src/utils/__tests__/fontService.test.ts --reporter=verbose && npx tsc --noEmit && ls public/fonts/*.ttf | wc -l\n- [x] **T02: Added TextObject to CanvasObject union and wired text tool into KonvaStage rendering, CanvasToolbar, ObjectPanel, ShapeProperties, and AlignmentBar with exhaustive switch coverage** — Extend the CanvasObject discriminated union with a TextObject type. Wire text objects into all canvas components: KonvaStage (render via Konva Text + case in getObjWidth/getObjHeight + text tool creation in handleStageMouseDown), CanvasToolbar (add 'text' to CanvasTool union and TOOLS array), ObjectPanel (add 'text' icon to TYPE_ICONS), and DesignCanvas (pass through). This follows the exact pattern established in S02 for adding object types.\n\n## Key Implementation Details\n- TextObject interface: extends BaseCanvasObject with type: 'text', text: string, fontFamily: string, fontSize: number, letterSpacing: number, lineHeight: number, fill: string, stroke: string, strokeWidth: number, width: number (for wrapping)\n- CanvasTool union in KonvaStage.tsx must add 'text' — this is imported by CanvasToolbar\n- KonvaStage renderObject switch: case 'text' renders from react-konva with fontFamily, fontSize, fill, stroke, strokeWidth, width, letterSpacing, lineHeight props\n- KonvaStage handleStageMouseDown switch: case 'text' creates a TextObject with defaults (text: 'Text', fontFamily: 'Roboto', fontSize: 24, letterSpacing: 0, lineHeight: 1.2)\n- KonvaStage getObjWidth for text: use obj.width (wrapping width) or estimate from fontSize * text.length * 0.6\n- KonvaStage getObjHeight for text: obj.fontSize * obj.lineHeight\n- KonvaStage onTransformEnd for text: scale width, keep fontSize unchanged (text wraps to new width)\n- ObjectPanel TYPE_ICONS: text → 'T'\n- ShapeProperties getWidth/getHeight: add case 'text' returning obj.width and obj.fontSize * obj.lineHeight\n- All switch statements must be exhaustive — TypeScript noFallthroughCasesInSwitch enforces this\n- TypeScript strict mode — no unused locals/params, erasableSyntaxOnly, use import type\n - Estimate: 1h\n - Files: app/src/types/canvas.ts, app/src/components/canvas/KonvaStage.tsx, app/src/components/canvas/CanvasToolbar.tsx,

property controls (content, font family, size, letter spacing, line height) and Convert to Paths button to ShapeProperties, wired through DesignCanvas** — Add text-specific property controls to ShapeProperties and implement the 'Convert to Paths' action that replaces a TextObject with path-based objects using fontService.textToPathData().\n\n## Text Property Controls (in ShapeProperties)\nWhen the selected object has type 'text', show:\n1. **Text content** — textarea input bound to obj.text\n2. **Font family** — dropdown/select populated from fontService.getAvailableFonts(), bound to obj.fontFamily\n3. **Font size** — number input (min 8, max 200, step 1), bound to obj.fontSize\n4. **Letter spacing** — number input (min -5, max 20, step 0.5), bound to obj.letterSpacing\n5. **Line height** — number input (min 0.5, max 3, step 0.1), bound to obj.lineHeight\n6. **Fill color** — color input (reuse existing pattern from hasFill), bound to obj.fill\n7. **Stroke color + weight** — reuse existing stroke controls\n8. **Convert to Paths button** — calls fontService.textToPathData(), then replaces the text object with a new path object (type 'image' with SVG data URL, or a new 'path' type if simpler)\n\n## Convert to Paths Implementation\n- Show confirmation dialog (window.confirm) since this is destructive\n- Call `textToPathData(obj.text, obj.fontFamily, obj.fontSize, obj.letterSpacing)` from fontService\n- Create SVG string from returned path data: ``\n- Convert SVG to Blob URL, create ImageObject replacing the TextObject at same x,y position\n- Use onUpdate to remove old text object and add new image object (or dispatch through a callback prop)\n\n## Integration Notes\n- fontService.ts from T01 provides loadFont(), getAvailableFonts(), textToPathData()\n- The text property controls should only show when object.type === 'text'\n- Existing stroke/fill/opacity/rotation controls still show for text objects\n- ShapeProperties receives onUpdate callback from DesignCanvas — convert-to-paths needs onUpdate + onAddObject + onRemoveObject, so ShapeProperties props may need extending, or the convert action can be handled via a new callback prop\n- DesignCanvas.tsx needs to pass the additional callback(s) to ShapeProperties\n - Estimate: 1h\n - Files: app/src/components/canvas/ShapeProperties.tsx,

Zero coupling — App calls Engine only via HTTP API. | Engine is proprietary IP that must be embeddable into future applications independently. Clean input/output contracts enable this. | No | human |\n| D002 | | architecture | Build order and gating strategy | Build Engine first (M001), then App canvas (M002), then Export+Deploy+Embed (M003). Human checkpoints gate each transition. | Brief explicitly mandates: validate engine output quality before building canvas UI, validate canvas before export/deploy. Engine is the hardest and most valuable piece. | No | human |\n| D003 | | engine | Post-processing replaces regex metadata extraction | postprocess_svg() pipeline replaces old _extract_svg_metadata() regex approach; all SVG paths are parsed into structured PathInfo objects with coordinates, area, island status | Structured path data is needed for DXF/JSON output generation, RDP simplification, and island detection. XML parsing is now necessary since we need actual coordinate data, not just counts. This supersedes D003's regex approach. | No | agent |\n| D004 | | architecture | Engine Docker image build strategy | Multi-stage build: builder stage compiles pypotrace with build-essential/libagg-dev/libpotrace-dev, runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl). Only engine source is copied — no App code. | Multi-stage keeps the runtime image small by excluding build tools. Copying only engine source enforces the Engine/App separation (D001). curl is included for Docker HEALTHCHECK. | Yes | agent |\n| D005 | | architecture | Frontend technology stack for Kerf App | Vite + React + TypeScript with plain CSS modules, Vitest for testing, raw fetch + FormData for engine API calls, no UI framework for V1 | Minimal dependency surface for a tool that needs fast iteration. The engine API uses multipart/form-data which works naturally with native fetch + FormData. CSS modules avoid global style conflicts without adding a framework. Vitest integrates natively with Vite's transform pipeline. No UI library needed — the app has a focused interface with ~8 components. | Yes | agent |\n| D006 | | frontend | React hook params stabilization strategy for useDebouncedTrace | JSON.stringify params in useEffect deps array, single-effect architecture | useCallback-based triggerTrace with object params caused infinite re-render loops because React creates new object references each render. JSON.stringify converts params to a stable string for dependency comparison, eliminating the need for callers to useMemo their params objects. Simpler API surface and no re-render bugs. | Yes | agent |\n| D007 | | architecture | Canvas object type system design | Discriminated union on `type` field: 'rect' \\| 'circle' \\| 'ellipse' \\| 'line' \\| 'image'. All objects share BaseCanvasObject (id, name, x, y, visible, locked, stroke, fill, opacity). Type-specific fields via intersection types. | TypeScript discriminated unions enable exhaustive type narrowing in switch/if statements, catching missing cases at compile time. Shared base keeps CRUD operations generic while type-specific panels (ShapeProperties) safely narrow to access unique fields. 'text' type will be added in S03. | Yes | agent |\n| D008 | | frontend | opentype.js integration strategy for font loading and text-to-path conversion | opentype.js v1.3.4 with dynamic import(), local type declarations, per-character glyph positioning for letter spacing, and Y-axis flip (canvas_y = ascender - font_y * scale) for canvas-compatible SVG path coordinates | opentype.js has no @types package, so local declarations are needed. The library's getPath() doesn't support letter spacing natively — manual per-character positioning with x-advance accumulation is required. Font coordinate system is Y-up while canvas is Y-down, requiring the ascender-based flip formula. Dynamic import() avoids bundling issues with the library's CommonJS/ESM dual packaging. | Yes | agent |\n| D009 | | frontend | Text-to-paths conversion strategy | Convert-to-paths uses a single onConvertToPath(textObjectId, imageObject) callback that generates an SVG Blob URL and creates an ImageObject replacement, reusing the existing image rendering pipeline | Reusing the ImageObject type and its existing Konva rendering avoids adding a new 'path' object type. A single callback keeps the prop interface simpler than separate onAddObject + onRemoveObject and makes the replacement atomic. The SVG Blob URL contains the path data with fill/stroke matching the original text object. | Yes | agent |\n"}],"isError":false,"timestamp":1774504914196}} +{"type":"message","id":"6c450060","parentId":"de6a1ce5","timestamp":"2026-03-26T06:01:58.490Z","message":{"role":"assistant","content":[{"type":"text","text":"Now I have all the evidence needed.

Add entries when you discover something worth remembering.\n\n## Rules\n\n| # | Scope | Rule | Why | Added |\n|---|-------|------|-----|-------|\n\n## Patterns\n\n| # | Pattern | Where | Notes |\n|---|---------|-------|-------|\n| P001 | Test images generated programmatically via numpy | engine/tests/ | No fixture image files checked in. Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n| P003 | PostProcessResult is the universal intermediate representation | engine/pipeline/postprocess.py → engine/output/ | All output generators (DXF, JSON, SVG) consume PostProcessResult. Never generate output directly from raw SVG strings. |\n| P004 | _format_response() for consistent multi-format API responses | engine/api/routes.py | DXF returns binary Response with X-Kerf-Metadata header; SVG/JSON return JSON envelopes. Use _format_response() for both /engine/trace and /engine/simplify. |\n| P005 | Preset-driven pipeline: resolve_params() merges preset → user | engine/presets/loader.py, engine/api/routes.py | Presets define defaults for all pipeline stages. User params override. Mode comes from preset unless user explicitly sets it. |\n| P006 | JSON.stringify for React hook dependency stabilization | app/src/hooks/useDebouncedTrace.ts | Object params in useEffect deps cause infinite loops (new ref each render). Stringify the params object and use the string in the deps array. Avoids requiring callers to useMemo. |\n| P007 | Vite dev proxy for engine API calls | app/vite.config.ts | `/engine/*` requests proxy to `http://localhost:8000`. API client uses relative URLs (`/engine/presets`). No CORS issues in dev because same-origin via proxy. |\n| P008 | CSS modules for views, global App.css for shared component styles | app/src/views/*.module.css, app/src/App.css | View-specific layout in CSS modules avoids conflicts. Shared styles (upload zone, preset cards, buttons) in App.css for cross-component reuse. |\n| P009 | opentype.js needs dynamic import() and local type declarations | app/src/utils/fontService.ts | No @types/opentype.js package exists. Use `const opentype = await import('opentype.js')` with `type OpentypeFont = any` for the Font object. Variable .ttf fonts work fine for glyph extraction. |\n| P010 | Font Y-axis flip: canvas_y = ascender - font_y * scale | app/src/utils/fontService.ts | opentype.js uses font coordinate system (Y-up) while canvas uses screen coordinates (Y-down). Apply `ascender * scale - font_y` to all Y values in path data. Without this, text renders upside-down. |\n| P011 | Letter spacing requires manual per-character glyph positioning | app/src/utils/fontService.ts | opentype.js getPath() doesn't support letter spacing. Must iterate characters, get individual glyph paths, accumulate x-advance + spacing per character, and compose the final SVG d-attribute manually. |\n| P012 | Adding new CanvasObject types requires exhaustive switch updates in 6 files | app/src/types/canvas.ts, KonvaStage, CanvasToolbar, ObjectPanel, ShapeProperties, AlignmentBar | TypeScript noFallthroughCasesInSwitch enforces exhaustive handling. When adding a new type to the CanvasObject union, all switch statements across these 6 files must be updated or compilation fails. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them. Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003). All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n| L007 | Docker build context must be project root, not engine/ | Dockerfile.engine uses `COPY engine/...` paths relative to project root | Always build with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` from project root | Docker |\n| L008 | Engine container has dual health endpoints | /health on root (main.py) and /engine/health on router (routes.py) both exist | Use /engine/health for Docker HEALTHCHECK and external probes for namespace consistency | engine API, Docker |\n| L009 | useCallback-based triggerTrace caused infinite re-render loops | Object params create new references each render, retriggering useEffect even when values are unchanged | Restructure hook to use single useEffect with JSON.stringify(params) in dependency array instead of useCallback-based approach | app hooks, React |\n| L010 | jest-canvas-mock crashes in Vitest with \"ReferenceError: jest is not defined\" | jest-canvas-mock internally calls jest.fn() in createImageBitmap.js — Jest globals don't exist in Vitest | Use vitest-canvas-mock (a Vitest-compatible fork) instead.

View 2 is a Konva.js-powered 2D design environment with artboard shapes, text objects, basic shapes, layers, alignment tools, and undo/redo.\"*\n\nLet me map each element:\n\n1. **Import & Convert view (View 1)** — ✅ S01 delivered: FileUpload, PresetSelector, ParameterSliders, SvgPreview, OutputInfoBar, Use This button\n2. **Engine API integration with live preview** — ✅ S01: typed API client, useDebouncedTrace hook with AbortController\n3. **Design Canvas (View 2)** — ✅ S02 delivered: KonvaStage, DesignCanvas view\n4. **Artboard shapes** — ✅ S02: shield, pennant, rect, circle, oval, square artboard shapes\n5. **Text objects** — ✅ S03: TextObject type, text tool, text property controls\n6. **Basic shapes** — ✅ S02: rect, circle, ellipse, line\n7. **Layers** — ✅ S02: ObjectPanel with z-order, visibility/lock toggles, rename, reorder\n8. **Alignment tools** — ✅ S02: 9 alignment/distribute functions, AlignmentBar component\n9. **Undo/redo** — ✅ S02: useCanvasState with useReducer+useRef, Ctrl+Z/Ctrl+Shift+Z, history capped at 50\n\n### Slice Delivery Audit\n\n**S01 Demo claim**: *\"Upload a PNG, see live preview with preset selection and slider controls, click 'Use This' to advance to canvas\"*\n- ✅ All components exist and are wired. 23 tests pass. API client, debounce hook, preset selector, parameter sliders, SVG preview, Use This button — all delivered.\n\n**S02 Demo claim**: *\"Create artboards in each shape, add/move/resize shapes, multi-select with alignment, undo/redo through history\"*\n- ✅ ArtboardSetup with 6 shape options, shape tools (rect/circle/ellipse/line), KonvaStage with Transformer/selection, ObjectPanel/AlignmentBar, undo/redo. 48 new tests (71 total). Zero TS errors.\n\n**S03 Demo claim**: *\"Add text objects, select fonts from picker, change size/spacing, convert text to paths — paths match original glyphs\"*\n- ✅ TextObject type added to union, text tool in toolbar, font family picker with 3 bundled fonts, font size/letter spacing/line height controls, Convert to Paths via fontService.textToPathData(). 24 new tests (95 total). Zero TS errors.\n\n### Cross-Slice Integration\n\n- **S01 → S02**: S01 provides `onUseThis(svgData, traceMetadata)` in App.tsx. S02 consumes this in DesignCanvas via props. ✅ Verified in S02 summary: \"wired into App.tsx to receive real svgData/traceMetadata props from View 1.\"\n- **S02 → S03**: S02 provides discriminated union CanvasObject type system. S03 extends it with TextObject. ✅ Verified: S03 requires S02's union and extends all 6 switch statements.\n- **No orphaned boundaries**: All provides/consumes align with what was built.\n\n### Requirement Coverage\n\nNo formal requirements exist in REQUIREMENTS.md — the project relies on milestone vision and slice demos as the specification. All vision elements are covered.\n\n### Verification Evidence\n\n- **95/95 tests pass** (7 test files) — confirmed via `npx vitest run`\n- **Zero TypeScript errors** — confirmed via `npx tsc --noEmit`\n- **All 25 key files exist** — confirmed via `ls -la`\n- **3 font files bundled** — confirmed\n- **9 decisions recorded** (D001-D009) — all relevant and consistent\n\n### Known Limitations (acceptable, not blocking)\n\n- CORS allows all origins (dev-appropriate, needs restriction for production M003)\n- SVG preview uses dangerouslySetInnerHTML (acceptable for engine-generated SVG)\n- No E2E integration tests with running engine (unit tests mock fetch)\n- Canvas components lack dedicated unit tests (verified via TypeScript + manual integration)\n- Convert-to-paths produces ImageObject with Blob URL, not first-class path type\n\nNone of these are material gaps — they're documented trade-offs and production-hardening items for M003."},{"type":"toolCall","id":"toolu_016A5yEwwRNMzPdYcipkWb4s","name":"gsd_validate_milestone","arguments":{"crossSliceIntegration":"## Cross-Slice Integration\n\n### S01 → S02 Boundary\n- **S01 provides:** ViewState routing in App.tsx, onUseThis callback passing SVG string + TraceMetadata, typed API client, TypeScript interfaces for engine types\n- **S02 consumes:** svgData and traceMetadata props in DesignCanvas, ViewState 'canvas' rendering\n- **Status:** ✅ Aligned — S02 summary confirms \"wired into App.tsx to receive real svgData/traceMetadata props from View 1\". App.tsx correctly passes props after ViewState transitions.\n\n### S02 → S03 Boundary\n- **S02 provides:** CanvasObject discriminated union (types/canvas.ts), KonvaStage rendering pipeline, ShapeProperties component, CanvasToolbar, ObjectPanel, AlignmentBar, useCanvasState hook\n- **S03 consumes:** Extends CanvasObject union with TextObject type, adds cases in all 6 switch statements (KonvaStage, CanvasToolbar, ObjectPanel, ShapeProperties, AlignmentBar, DesignCanvas)\n- **Status:** ✅ Aligned — S03 summary confirms exhaustive switch coverage under strict TypeScript mode.

Scaffolded the app/ directory as a Vite + React + TypeScript project with a dev proxy forwarding /engine/* requests to localhost:8000. Built typed API client (getPresets, traceImage, simplifyVector) with AbortSignal support and error handling. Established the test infrastructure with Vitest + jsdom + testing-library. 9 tests pass.\n\n**T02 — UI Shell:** Created the two-column ImportConvert layout (left: controls, right: preview). Built FileUpload component with drag-and-drop + file input fallback, thumbnail preview via URL.createObjectURL, and SVG file detection for mode switching. Built PresetSelector that fetches presets from the engine API on mount with AbortController cleanup, renders preset cards with selection highlighting, and auto-selects 'sign' as default. Set up ViewState routing in App.tsx (import → canvas → export).\n\n**T03 — Core Interaction Loop (highest risk):** Created the useDebouncedTrace custom hook — the central piece — which debounces API calls on params/preset/file change, aborts in-flight requests via AbortController, and routes SVG uploads to simplifyVector() instead of traceImage(). Solved infinite re-render loops by stabilizing params via JSON.stringify in the useEffect dependency array. Built ParameterSliders with mode-aware controls (potrace shows epsilon/turdsize/alphamax; vtracer shows epsilon/filter_speckle/corner_threshold). Built SvgPreview with responsive SVG rendering (strips width/height, preserves viewBox), loading spinner, and error states. Wired the complete live re-trace loop in ImportConvert. 7 hook tests pass.\n\n**T04 — Polish & Completion:** Created OutputInfoBar with color-coded stats (green normal, yellow >5000 nodes, red open paths), warnings display, and processing time. Wired the Use This button (disabled when no SVG output) that passes SVG + metadata to App.tsx for View 2 consumption. 7 component tests pass.\n\nAll 23 tests pass.

Built the central `useCanvasState` hook using a useReducer + useRef pattern — reducer drives re-renders for current state, ref holds undo/redo history stacks without triggering renders. Select/deselect are excluded from the undo stack (UI-only concern). History is capped at 50 entries. Created artboard shape utilities (shield/pennant SVG paths, dimension presets, unit conversion), 9 pure alignment/distribute functions, and the `ArtboardSetup` modal component. Installed konva, react-konva, and vitest-canvas-mock. 48 new tests passing.\n\n**T02 — Rendering Layer:** Created `KonvaStage` rendering artboard backgrounds (Rect/Circle/Ellipse/Path based on shape config), mapping all canvas objects to Konva primitives with drag/transform handlers, Transformer synced to selected nodes, and rubber-band multi-select rectangle. Built `DesignCanvas` view container with ResizeObserver-driven sizing, artboard setup flow, and SVG import (Blob URL → Image element → Konva.Image with auto-scale). Wired into `App.tsx` to receive real svgData/traceMetadata props from View 1.\n\n**T03 — Panel System:** Built four panel components: `ObjectPanel` (layer list in reverse z-order with drag reorder, visibility/lock toggles, rename), `AlignmentBar` (6 alignment + 2 distribute + center-on-artboard), `CanvasToolbar` (tool switcher, undo/redo, grid toggle, zoom controls), and `ShapeProperties` (stroke/fill/dimensions/line-style editing with discriminated union narrowing). All wired to useCanvasState in DesignCanvas.\n\n**T04 — Shortcuts & Integration:** Added window-level keyboard shortcuts (Ctrl+Z undo, Ctrl+Shift+Z redo, Delete/Backspace remove, Escape deselect, Ctrl+A select all) with activeElement guard to skip input fields. Verified full integration: View 1 → Use This → Artboard Setup → Canvas with imported SVG. All 71 tests pass, zero TypeScript errors.\n\n## Verification\n\nRan `cd app && npx vitest run --reporter=verbose` — 71 tests pass across 6 test files, 0 failures (exit 0). Ran `cd app && npx tsc --noEmit` — zero type errors under strict mode with noUnusedLocals/noUnusedParameters (exit 0).\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nUsed vitest-canvas-mock instead of jest-canvas-mock (plan specified jest-canvas-mock but it crashes in Vitest because it internally calls jest.fn()). This was identified in T01 and recorded as L010 in KNOWLEDGE.md.\n\n## Known Limitations\n\nCanvas components (KonvaStage, DesignCanvas panels) do not have dedicated unit tests — they were verified via TypeScript compilation and manual integration. Konva rendering in jsdom is limited since canvas operations are mocked. Drag-to-reorder in ObjectPanel uses simple index swapping, not full drag-and-drop library.\n\n## Follow-ups\n\nS03 will add 'text' type to the CanvasObject discriminated union and integrate opentype.js for font loading and text-to-path conversion. ShapeProperties panel will need a text-specific section. The canvas object type system (D008) was designed to accommodate this extension.\n\n## Files Created/Modified\n\n- `app/src/types/canvas.ts` — New — discriminated union type system for canvas objects (rect, circle, ellipse, line, image), ArtboardConfig, CanvasState, and CanvasAction types\n- `app/src/hooks/useCanvasState.ts` — New — central state management hook with useReducer+useRef for CRUD, selection, undo/redo, reorder, visibility/lock\n- `app/src/hooks/__tests__/useCanvasState.test.ts` — New — 20 tests covering all useCanvasState operations including undo/redo edge cases\n- `app/src/utils/artboardShapes.ts` — New — artboard shape presets, shield/pennant SVG path generators, toPx/fromPx unit conversion, artboardClipPath\n- `app/src/utils/__tests__/artboardShapes.test.ts` — New — 15 tests for artboard presets, path generation, unit conversion, clip paths\n- `app/src/utils/alignment.ts` — New — 9 pure alignment/distribute/center functions for canvas objects\n- `app/src/utils/__tests__/alignment.test.ts` — New — 13 tests for alignment, distribution, and center-on-artboard\n- `app/src/components/canvas/ArtboardSetup.tsx` — New — modal for artboard shape/size/unit selection on entering canvas view\n- `app/src/components/canvas/KonvaStage.tsx` — New — Konva Stage+Layer rendering artboard, all object types, Transformer, rubber-band selection\n- `app/src/components/canvas/ObjectPanel.tsx` — New — layer management panel with z-order list, reorder, visibility/lock toggles, rename\n- `app/src/components/canvas/AlignmentBar.tsx` — New — alignment and distribution toolbar consuming alignment utils\n- `app/src/components/canvas/CanvasToolbar.tsx` — New — tool switcher, undo/redo, grid toggle, zoom controls\n- `app/src/components/canvas/ShapeProperties.tsx` — New — property editor for selected shape (stroke, fill, dimensions, line style, opacity)\n- `app/src/views/DesignCanvas.tsx` — New — View 2 container wiring KonvaStage + all panels to useCanvasState, SVG import, keyboard shortcuts\n- `app/src/views/DesignCanvas.module.css` — New — CSS module for DesignCanvas layout\n- `app/src/App.tsx` — Modified — wired DesignCanvas with svgData/traceMetadata props, removed underscore prefixes\n- `app/src/App.css` — Modified — added comprehensive canvas UI styles (toolbar, panels, artboard setup, shape properties, alignment bar)\n- `app/src/test-setup.ts` — Modified — added vitest-canvas-mock import for Konva testing\n- `app/package.json` — Modified — added konva, react-konva, vitest-canvas-mock dependencies\n\n---\n\n### S03 Summary\nSource: `.gsd/milestones/M002/slices/S03/S03-SUMMARY.md`\n\n---\nid: S03\nparent: M002\nmilestone: M002\nprovides:\n -

The text-to-path conversion handles the font-to-canvas coordinate system transformation (Y-axis flip: `ascender * scale - font_y`) and implements manual per-character glyph positioning to support letter spacing (opentype.js's `getPath()` doesn't support it natively). Three OFL-licensed Google Fonts (Roboto, Open Sans, Lato) were bundled as .ttf files in `app/public/fonts/` with corresponding `@font-face` declarations in App.css. 24 unit tests cover the font registry, loading/caching/deduplication/error handling, family resolution, and text-to-path conversion including dimension scaling, letter spacing arithmetic, coordinate system validation, and edge cases.\n\n**T02 — TextObject type and canvas integration.** Added the `TextObject` interface to the `CanvasObject` discriminated union in `canvas.ts` with text-specific fields (text, fontFamily, fontSize, letterSpacing, lineHeight, fill, stroke, strokeWidth, width). Wired the text type through all six canvas component files: KonvaStage (rendering via ``, tool creation, sizing, transform that scales width only), CanvasToolbar (added 'text' to TOOLS array), ObjectPanel (added 'T' icon), ShapeProperties (getWidth/getHeight cases), and AlignmentBar (toBoundingRect case). All switch statements maintain exhaustive coverage under TypeScript strict mode. Text objects default to fill `#000000` and stroke `transparent` for natural text appearance.\n\n**T03 — Text property controls and Convert to Paths.** Extended ShapeProperties with text-specific controls that render when the selected object has type 'text': textarea for content, font family dropdown populated from `fontService.getAvailableFonts()`, and numeric inputs for font size (8–200), letter spacing (-5–20), and line height (0.5–3). Added a \"Convert to Paths\" button that calls `fontService.textToPathData()`, wraps the result in an SVG string, creates a Blob URL, and replaces the TextObject with an ImageObject via a new `onConvertToPath` callback. The conversion shows a confirmation dialog (destructive action) and a \"Converting…\" disabled state during the async operation. DesignCanvas passes the handler that atomically removes the text object and adds the replacement image.\n\n## Verification\n\nTypeScript: `npx tsc --noEmit` — zero errors under strict mode with verbatimModuleSyntax, noUnusedLocals, noUnusedParameters. Tests: `npx vitest run --reporter=verbose` — all 95 tests pass across 7 test files (24 fontService tests + 71 existing tests). Font files: 3 .ttf files confirmed in app/public/fonts/.\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nT02 added case 'text' to AlignmentBar.tsx toBoundingRect — not listed in task plan but required for exhaustive switch coverage. T03 used a single onConvertToPath(textObjectId, imageObject) callback instead of separate onAddObject + onRemoveObject as the plan suggested — simpler and keeps the replacement atomic.\n\n## Known Limitations\n\nConvert-to-paths produces an ImageObject with a Blob URL — the SVG path data is embedded in the URL, not stored as a first-class path object type. Multi-line text is supported by Konva's text wrapping (width property) but the text-to-path conversion treats input as a single line. Font loading requires network fetch of .ttf files — no offline/preload strategy beyond browser caching.\n\n## Follow-ups\n\nNone.\n\n## Files Created/Modified\n\n- `app/src/utils/fontService.ts` — New — font loading, caching, text-to-path conversion service using opentype.js\n- `app/src/utils/__tests__/fontService.test.ts` — New — 24 unit tests for fontService (registry, loading, caching, path conversion)\n- `app/public/fonts/Roboto-Regular.ttf` — New — bundled OFL-licensed Roboto variable font\n- `app/public/fonts/OpenSans-Regular.ttf` — New — bundled OFL-licensed Open Sans variable font\n- `app/public/fonts/Lato-Regular.ttf` — New — bundled OFL-licensed Lato font\n- `app/src/App.css` — Modified — added @font-face declarations for Roboto, Open Sans, Lato\n- `app/package.json` — Modified — added opentype.js v1.3.4 dependency\n- `app/src/types/canvas.ts` — Modified — added TextObject interface and extended CanvasObject union with 'text' type\n- `app/src/components/canvas/KonvaStage.tsx` — Modified — text rendering, text tool creation, text sizing/transform, 'text' in CanvasTool union\n- `app/src/components/canvas/CanvasToolbar.tsx` — Modified — added text tool to TOOLS array\n- `app/src/components/canvas/ObjectPanel.tsx` — Modified — added 'T' icon for text objects in TYPE_ICONS\n- `app/src/components/canvas/ShapeProperties.tsx` — Modified — text property controls (content, font family, size, letter spacing, line height), Convert to Paths button, getWidth/getHeight cases\n- `app/src/components/canvas/AlignmentBar.tsx` — Modified — added text case to toBoundingRect for exhaustive switch\n- `app/src/views/DesignCanvas.tsx` — Modified — added onConvertToPath handler wiring ShapeProperties to canvas state\n\n---\n\n[...truncated 11 sections]\n\nThen:\n1. Use the **Milestone Summary** output template from the inlined context above\n2. \n3. **Verify code changes exist.** Run `git diff --stat HEAD $(git merge-base HEAD main) -- ':!.gsd/'` (or the equivalent for the integration branch). If no non-`.gsd/` files appear in the diff, the milestone produced only planning artifacts and no actual code. Record this as a **verification failure**.\n4. Verify each **success criterion** from the milestone definition in `.gsd/milestones/M002/M002-ROADMAP.md`. For each criterion, confirm it was met with specific evidence from slice summaries, test results, or observable behavior. Record any criterion that was NOT met as a **verification failure**.\n5. Verify the milestone's **definition of done** — all slices are `[x]`, all slice summaries exist, and any cross-slice integration points work correctly. Record any unmet items as a **verification failure**.\n6. Validate **requirement status transitions**. For each requirement that changed status during this milestone, confirm the transition is supported by evidence. Requirements can move between Active, Validated, Deferred, Blocked, or Out of Scope — but only with proof.\n\n### Verification Gate — STOP if verification failed\n\n**If ANY verification failure was recorded in steps 3, 4, or 5, you MUST follow the failure path below. Do NOT proceed to step 7.**\n\n**Failure path** (verification failed):\n- Do NOT call `gsd_complete_milestone` — the milestone must not be marked as complete.\n- Do NOT update `.gsd/PROJECT.md` to reflect completion.\n- Do NOT update `.gsd/REQUIREMENTS.md` to mark requirements as validated.\n- Write a clear summary of what failed and why to help the next attempt.\n- Say: \"Milestone M002 verification FAILED — not complete.\" and stop.\n\n**Success path** (all verifications passed — continue with steps 7–11):\n\n7. **Persist completion through `gsd_complete_milestone`.** Call it with: `milestoneId`, `title`, `oneLiner`, `narrative`, `successCriteriaResults`, `definitionOfDoneResults`, `requirementOutcomes`, `keyDecisions`, `keyFiles`, `lessonsLearned`, `followUps`, `deviations`, `verificationPassed: true`. The tool updates the milestone status in the DB, renders `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M002/M002-SUMMARY.md`, and validates all slices are complete before proceeding.\n8. For each requirement whose status changed in step 6, call `gsd_requirement_update` with the requirement ID and updated `status` and `validation` fields — the tool regenerates `.gsd/REQUIREMENTS.md` automatically.\n9. Update `.gsd/PROJECT.md` to reflect milestone completion and current project state.\n10. Review all slice summaries for cross-cutting lessons, patterns, or gotchas that emerged during this milestone. Append any non-obvious, reusable insights to `.gsd/KNOWLEDGE.md`.\n11. Do not commit manually — the system auto-commits your changes after this unit completes.\n- Say: \"Milestone M002 complete.\"\n\n**Important:** Do NOT skip the code change verification, success criteria, or definition of done verification (steps 3-5). The milestone summary must reflect actual verified outcomes, not assumed success. Verification failures BLOCK completion — there is no override. The milestone stays in its current state until issues are resolved and verification is re-run.\n\n**File system safety:** When scanning milestone directories for evidence, use `ls` or `find` to list directory contents first — never pass a directory path (e.g. `tasks/`, `slices/`) directly to the `read` tool. The `read` tool only accepts file paths, not directories.","display":false,"id":"55c583f1","parentId":"c7a0930f","timestamp":"2026-03-26T06:03:26.918Z"} +{"type":"message","id":"d62e164b","parentId":"55c583f1","timestamp":"2026-03-26T06:03:31.341Z","message":{"role":"assistant","content":[{"type":"text","text":"\n\nI'll verify the milestone systematically before completing it.\n\n## Step 3: Verify code changes exist"},{"type":"toolCall","id":"toolu_01ELiVi9JhcnRYfnS3CEJchE","name":"bash","arguments":{"command":"cd /home/aux/development/xpltdco/kerf-engine && git diff --stat HEAD $(git merge-base HEAD main) -- ':!.gsd/' 2>/dev/null | tail -30"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":3,"output":124,"cacheRead":49688,"cacheWrite":9244,"totalTokens":59059,"cost":{"input":0.000015000000000000002,"output":0.0031000000000000003,"cacheRead":0.024843999999999998,"cacheWrite":0.057775,"total":0.085734}},"stopReason":"toolUse","timestamp":1774505006916}} +{"type":"message","id":"8a957365","parentId":"d62e164b","timestamp":"2026-03-26T06:03:31.353Z","message":{"role":"toolResult","toolCallId":"toolu_01ELiVi9JhcnRYfnS3CEJchE","toolName":"bash","content":[{"type":"text","text":"(no output)"}],"isError":false,"timestamp":1774505011352}} +{"type":"message","id":"292a6633","parentId":"8a957365","timestamp":"2026-03-26T06:03:34.464Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_01WM2PqyzYUwkKqQqXe8BeKE","name":"bash","arguments":{"command":"cd /home/aux/development/xpltdco/kerf-engine && git branch -a"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":74,"cacheRead":58932,"cacheWrite":141,"totalTokens":59148,"cost":{"input":0.000005,"output":0.00185,"cacheRead":0.029466,"cacheWrite":0.0008812500000000001,"total":0.03220225}},"stopReason":"toolUse","timestamp":1774505011353}} +{"type":"message","id":"0b1f8556","parentId":"292a6633","timestamp":"2026-03-26T06:03:34.475Z","message":{"role":"toolResult","toolCallId":"toolu_01WM2PqyzYUwkKqQqXe8BeKE","toolName":"bash","content":[{"type":"text","text":"* main\n"}],"isError":false,"timestamp":1774505014474}} +{"type":"message","id":"4f4b6b46","parentId":"0b1f8556","timestamp":"2026-03-26T06:03:38.327Z","message":{"role":"assistant","content":[{"type":"text","text":"Only `main` branch exists.

Zero coupling — App calls Engine only via HTTP API. | Engine is proprietary IP that must be embeddable into future applications independently. Clean input/output contracts enable this. | No | human |\n| D002 | | architecture | Build order and gating strategy | Build Engine first (M001), then App canvas (M002), then Export+Deploy+Embed (M003). Human checkpoints gate each transition. | Brief explicitly mandates: validate engine output quality before building canvas UI, validate canvas before export/deploy. Engine is the hardest and most valuable piece. | No | human |\n| D003 | | engine | Post-processing replaces regex metadata extraction | postprocess_svg() pipeline replaces old _extract_svg_metadata() regex approach; all SVG paths are parsed into structured PathInfo objects with coordinates, area, island status | Structured path data is needed for DXF/JSON output generation, RDP simplification, and island detection. XML parsing is now necessary since we need actual coordinate data, not just counts. This supersedes D003's regex approach. | No | agent |\n| D004 | | architecture | Engine Docker image build strategy | Multi-stage build: builder stage compiles pypotrace with build-essential/libagg-dev/libpotrace-dev, runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl). Only engine source is copied — no App code. | Multi-stage keeps the runtime image small by excluding build tools. Copying only engine source enforces the Engine/App separation (D001). curl is included for Docker HEALTHCHECK. | Yes | agent |\n| D005 | | architecture | Frontend technology stack for Kerf App | Vite + React + TypeScript with plain CSS modules, Vitest for testing, raw fetch + FormData for engine API calls, no UI framework for V1 | Minimal dependency surface for a tool that needs fast iteration. The engine API uses multipart/form-data which works naturally with native fetch + FormData. CSS modules avoid global style conflicts without adding a framework. Vitest integrates natively with Vite's transform pipeline. No UI library needed — the app has a focused interface with ~8 components. | Yes | agent |\n| D006 | | frontend | React hook params stabilization strategy for useDebouncedTrace | JSON.stringify params in useEffect deps array, single-effect architecture | useCallback-based triggerTrace with object params caused infinite re-render loops because React creates new object references each render. JSON.stringify converts params to a stable string for dependency comparison, eliminating the need for callers to useMemo their params objects. Simpler API surface and no re-render bugs. | Yes | agent |\n| D007 | | architecture | Canvas object type system design | Discriminated union on `type` field: 'rect' \\| 'circle' \\| 'ellipse' \\| 'line' \\| 'image'. All objects share BaseCanvasObject (id, name, x, y, visible, locked, stroke, fill, opacity). Type-specific fields via intersection types. | TypeScript discriminated unions enable exhaustive type narrowing in switch/if statements, catching missing cases at compile time. Shared base keeps CRUD operations generic while type-specific panels (ShapeProperties) safely narrow to access unique fields. 'text' type will be added in S03. | Yes | agent |\n| D008 | | frontend | opentype.js integration strategy for font loading and text-to-path conversion | opentype.js v1.3.4 with dynamic import(), local type declarations, per-character glyph positioning for letter spacing, and Y-axis flip (canvas_y = ascender - font_y * scale) for canvas-compatible SVG path coordinates | opentype.js has no @types package, so local declarations are needed. The library's getPath() doesn't support letter spacing natively — manual per-character positioning with x-advance accumulation is required. Font coordinate system is Y-up while canvas is Y-down, requiring the ascender-based flip formula. Dynamic import() avoids bundling issues with the library's CommonJS/ESM dual packaging. | Yes | agent |\n| D009 | | frontend | Text-to-paths conversion strategy | Convert-to-paths uses a single onConvertToPath(textObjectId, imageObject) callback that generates an SVG Blob URL and creates an ImageObject replacement, reusing the existing image rendering pipeline | Reusing the ImageObject type and its existing Konva rendering avoids adding a new 'path' object type. A single callback keeps the prop interface simpler than separate onAddObject + onRemoveObject and makes the replacement atomic. The SVG Blob URL contains the path data with fill/stroke matching the original text object. | Yes | agent |\n"}],"isError":false,"timestamp":1774505119142}} +{"type":"message","id":"bff27c41","parentId":"7afc9c95","timestamp":"2026-03-26T06:05:22.767Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_01TgSi19dLWqLzjjhkgyo5ay","name":"read","arguments":{"path":".gsd/KNOWLEDGE.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":58,"cacheRead":73045,"cacheWrite":1301,"totalTokens":74405,"cost":{"input":0.000005,"output":0.0014500000000000001,"cacheRead":0.0365225,"cacheWrite":0.00813125,"total":0.04610875}},"stopReason":"toolUse","timestamp":1774505119143}} +{"type":"message","id":"9a61a358","parentId":"bff27c41","timestamp":"2026-03-26T06:05:22.771Z","message":{"role":"toolResult","toolCallId":"toolu_01TgSi19dLWqLzjjhkgyo5ay","toolName":"read","content":[{"type":"text","text":"# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit.

Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n| P003 | PostProcessResult is the universal intermediate representation | engine/pipeline/postprocess.py → engine/output/ | All output generators (DXF, JSON, SVG) consume PostProcessResult. Never generate output directly from raw SVG strings. |\n| P004 | _format_response() for consistent multi-format API responses | engine/api/routes.py | DXF returns binary Response with X-Kerf-Metadata header; SVG/JSON return JSON envelopes. Use _format_response() for both /engine/trace and /engine/simplify. |\n| P005 | Preset-driven pipeline: resolve_params() merges preset → user | engine/presets/loader.py, engine/api/routes.py | Presets define defaults for all pipeline stages. User params override. Mode comes from preset unless user explicitly sets it. |\n| P006 | JSON.stringify for React hook dependency stabilization | app/src/hooks/useDebouncedTrace.ts | Object params in useEffect deps cause infinite loops (new ref each render). Stringify the params object and use the string in the deps array. Avoids requiring callers to useMemo. |\n| P007 | Vite dev proxy for engine API calls | app/vite.config.ts | `/engine/*` requests proxy to `http://localhost:8000`. API client uses relative URLs (`/engine/presets`). No CORS issues in dev because same-origin via proxy. |\n| P008 | CSS modules for views, global App.css for shared component styles | app/src/views/*.module.css, app/src/App.css | View-specific layout in CSS modules avoids conflicts. Shared styles (upload zone, preset cards, buttons) in App.css for cross-component reuse. |\n| P009 | opentype.js needs dynamic import() and local type declarations | app/src/utils/fontService.ts | No @types/opentype.js package exists. Use `const opentype = await import('opentype.js')` with `type OpentypeFont = any` for the Font object. Variable .ttf fonts work fine for glyph extraction. |\n| P010 | Font Y-axis flip: canvas_y = ascender - font_y * scale | app/src/utils/fontService.ts | opentype.js uses font coordinate system (Y-up) while canvas uses screen coordinates (Y-down). Apply `ascender * scale - font_y` to all Y values in path data. Without this, text renders upside-down. |\n| P011 | Letter spacing requires manual per-character glyph positioning | app/src/utils/fontService.ts | opentype.js getPath() doesn't support letter spacing. Must iterate characters, get individual glyph paths, accumulate x-advance + spacing per character, and compose the final SVG d-attribute manually. |\n| P012 | Adding new CanvasObject types requires exhaustive switch updates in 6 files | app/src/types/canvas.ts, KonvaStage, CanvasToolbar, ObjectPanel, ShapeProperties, AlignmentBar | TypeScript noFallthroughCasesInSwitch enforces exhaustive handling. When adding a new type to the CanvasObject union, all switch statements across these 6 files must be updated or compilation fails. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them. Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003).

Built the complete Import & Convert view: drag-and-drop file upload with thumbnail preview and SVG detection, preset selector that fetches from the engine API, mode-aware parameter sliders (potrace vs vtracer controls), responsive SVG preview, and a color-coded output stats bar. The central innovation was the useDebouncedTrace hook which debounces API calls on parameter/file changes with AbortController cancellation, routing SVG uploads to the simplify endpoint instead of trace. Solved a critical infinite re-render loop by stabilizing object params via JSON.stringify in useEffect dependencies (D006, P006). Added CORSMiddleware to the engine for browser access and a Vite dev proxy for seamless API calls (P007). The Use This button passes SVG + TraceMetadata to View 2.\n\n**S02 — Design Canvas Core (View 2):** Created the Konva.js-powered 2D design environment. Established a discriminated union type system for canvas objects (rect, circle, ellipse, line, image) with shared BaseCanvasObject (D007/D008). Built useCanvasState — the central state management hook using useReducer + useRef — with full CRUD, selection (excluded from undo stack), undo/redo (history capped at 50), reorder, and visibility/lock toggle. Created artboard shape utilities (shield, pennant SVG paths, dimension presets, unit conversion). Built KonvaStage with artboard rendering, shape creation tools, drag/transform handlers, Transformer synced to selected nodes, and rubber-band multi-select. Delivered a four-panel system: ObjectPanel (z-order layer management), AlignmentBar (6 align + 2 distribute + center-on-artboard), CanvasToolbar (tools, undo/redo, grid, zoom), and ShapeProperties (stroke/fill/dimensions editing). Added keyboard shortcuts (Ctrl+Z, Ctrl+Shift+Z, Delete, Escape, Ctrl+A). SVG import from View 1 uses Blob URL → Image element → Konva.Image with auto-scale to fit artboard.\n\n**S03 — Text System + Font Loading:** Extended the canvas with text objects via opentype.js v1.3.4. Built fontService — a utility module that fetches .ttf fonts from the public directory, caches parsed Font objects with in-flight deduplication, and converts text to SVG path data. Solved the font-to-canvas coordinate transformation (Y-axis flip: ascender * scale - font_y) and implemented manual per-character glyph positioning for letter spacing support (P010, P011). Bundled three OFL-licensed Google Fonts (Roboto, Open Sans, Lato). Added TextObject to the discriminated union with exhaustive switch updates across 6 files (P012). Built text property controls (content, font family, size, letter spacing, line height) and Convert to Paths — an atomic text-to-image replacement via SVG Blob URL (D009).\n\nThe cross-slice integration chain works: View 1 uploads → engine vectorizes → live preview → Use This → Artboard Setup → Canvas with imported SVG → add shapes/text → manipulate with tools/alignment/properties → undo/redo through history.","oneLiner":"Built the complete React frontend with Import & Convert view (View 1) integrating the engine API for live vectorization preview, and a Konva.js-powered Design Canvas (View 2) with artboard shapes, basic shapes, text objects with font loading and text-to-path conversion, layers, alignment tools, and undo/redo.","requirementOutcomes":"No formal requirements (RXXX) are tracked for this project.

This milestone delivers the final end-to-end experience: upload → design → export → download.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Export Flow (View 3) + DXF Generation | high — dxf scale accuracy and geometry quality | — | ⬜ | Design a sign with text + imported vector, export as DXF, open in Inkscape/LightBurn with correct geometry and scale |\n| S02 | Docker Packaging + README | low — docker packaging is well-understood pattern | S01 | ⬜ | docker-compose up starts all services; Engine container runs independently; healthchecks pass |\n| S03 | Embed Mode | medium — shadow dom + konva.js + font loading interactions | S02 | ⬜ | Embed snippet in plain HTML page; component renders; styles don't bleed; download works from embedded context |\n\n---\n\n### Decisions\nSource: `.gsd/DECISIONS.md`\n\n# Decisions Register\n\n\n\n| # | When | Scope | Decision | Choice | Rationale | Revisable? | Made By |\n|---|------|-------|----------|--------|-----------|------------|---------|\n| D001 | | architecture | Engine/App architectural relationship | Engine is standalone module, App is a consumer. Zero coupling — App calls Engine only via HTTP API. | Engine is proprietary IP that must be embeddable into future applications independently. Clean input/output contracts enable this. | No | human |\n| D002 | | architecture | Build order and gating strategy | Build Engine first (M001), then App canvas (M002), then Export+Deploy+Embed (M003). Human checkpoints gate each transition. | Brief explicitly mandates: validate engine output quality before building canvas UI, validate canvas before export/deploy. Engine is the hardest and most valuable piece. | No | human |\n| D003 | | engine | Post-processing replaces regex metadata extraction | postprocess_svg() pipeline replaces old _extract_svg_metadata() regex approach; all SVG paths are parsed into structured PathInfo objects with coordinates, area, island status | Structured path data is needed for DXF/JSON output generation, RDP simplification, and island detection. XML parsing is now necessary since we need actual coordinate data, not just counts. This supersedes D003's regex approach. | No | agent |\n| D004 | | architecture | Engine Docker image build strategy | Multi-stage build: builder stage compiles pypotrace with build-essential/libagg-dev/libpotrace-dev, runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl). Only engine source is copied — no App code. | Multi-stage keeps the runtime image small by excluding build tools. Copying only engine source enforces the Engine/App separation (D001). curl is included for Docker HEALTHCHECK. | Yes | agent |\n| D005 | | architecture | Frontend technology stack for Kerf App | Vite + React + TypeScript with plain CSS modules, Vitest for testing, raw fetch + FormData for engine API calls, no UI framework for V1 | Minimal dependency surface for a tool that needs fast iteration. The engine API uses multipart/form-data which works naturally with native fetch + FormData. CSS modules avoid global style conflicts without adding a framework. Vitest integrates natively with Vite's transform pipeline. No UI library needed — the app has a focused interface with ~8 components. | Yes | agent |\n| D006 | | frontend | React hook params stabilization strategy for useDebouncedTrace | JSON.stringify params in useEffect deps array, single-effect architecture | useCallback-based triggerTrace with object params caused infinite re-render loops because React creates new object references each render. JSON.stringify converts params to a stable string for dependency comparison, eliminating the need for callers to useMemo their params objects. Simpler API surface and no re-render bugs. | Yes | agent |\n| D007 | | architecture | Canvas object type system design | Discriminated union on `type` field: 'rect' \\| 'circle' \\| 'ellipse' \\| 'line' \\| 'image'. All objects share BaseCanvasObject (id, name, x, y, visible, locked, stroke, fill, opacity). Type-specific fields via intersection types. | TypeScript discriminated unions enable exhaustive type narrowing in switch/if statements, catching missing cases at compile time. Shared base keeps CRUD operations generic while type-specific panels (ShapeProperties) safely narrow to access unique fields. 'text' type will be added in S03. | Yes | agent |\n| D008 | | frontend | opentype.js integration strategy for font loading and text-to-path conversion | opentype.js v1.3.4 with dynamic import(), local type declarations, per-character glyph positioning for letter spacing, and Y-axis flip (canvas_y = ascender - font_y * scale) for canvas-compatible SVG path coordinates | opentype.js has no @types package, so local declarations are needed. The library's getPath() doesn't support letter spacing natively — manual per-character positioning with x-advance accumulation is required. Font coordinate system is Y-up while canvas is Y-down, requiring the ascender-based flip formula. Dynamic import() avoids bundling issues with the library's CommonJS/ESM dual packaging. | Yes | agent |\n| D009 | | frontend | Text-to-paths conversion strategy | Convert-to-paths uses a single onConvertToPath(textObjectId, imageObject) callback that generates an SVG Blob URL and creates an ImageObject replacement, reusing the existing image rendering pipeline | Reusing the ImageObject type and its existing Konva rendering avoids adding a new 'path' object type. A single callback keeps the prop interface simpler than separate onAddObject + onRemoveObject and makes the replacement atomic. The SVG Blob URL contains the path data with fill/stroke matching the original text object. | Yes | agent |\n\n---\n\n### Project Knowledge\nSource: `.gsd/KNOWLEDGE.md`\n\n# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit. Add entries when you discover something worth remembering.\n\n## Rules\n\n| # | Scope | Rule | Why | Added |\n|---|-------|------|-----|-------|\n\n## Patterns\n\n| # | Pattern | Where | Notes |\n|---|---------|-------|-------|\n| P001 | Test images generated programmatically via numpy | engine/tests/ | No fixture image files checked in. Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n| P003 | PostProcessResult is the universal intermediate representation | engine/pipeline/postprocess.py → engine/output/ | All output generators (DXF, JSON, SVG) consume PostProcessResult. Never generate output directly from raw SVG strings. |\n| P004 | _format_response() for consistent multi-format API responses | engine/api/routes.py | DXF returns binary Response with X-Kerf-Metadata header; SVG/JSON return JSON envelopes. Use _format_response() for both /engine/trace and /engine/simplify. |\n| P005 | Preset-driven pipeline: resolve_params() merges preset → user | engine/presets/loader.py, engine/api/routes.py | Presets define defaults for all pipeline stages. User params override. Mode comes from preset unless user explicitly sets it. |\n| P006 | JSON.stringify for React hook dependency stabilization | app/src/hooks/useDebouncedTrace.ts | Object params in useEffect deps cause infinite loops (new ref each render). Stringify the params object and use the string in the deps array. Avoids requiring callers to useMemo. |\n| P007 | Vite dev proxy for engine API calls | app/vite.config.ts | `/engine/*` requests proxy to `http://localhost:8000`. API client uses relative URLs (`/engine/presets`). No CORS issues in dev because same-origin via proxy. |\n| P008 | CSS modules for views, global App.css for shared component styles | app/src/views/*.module.css, app/src/App.css | View-specific layout in CSS modules avoids conflicts. Shared styles (upload zone, preset cards, buttons) in App.css for cross-component reuse. |\n| P009 | opentype.js needs dynamic import() and local type declarations | app/src/utils/fontService.ts | No @types/opentype.js package exists. Use `const opentype = await import('opentype.js')` with `type OpentypeFont = any` for the Font object. Variable .ttf fonts work fine for glyph extraction. |\n| P010 | Font Y-axis flip: canvas_y = ascender - font_y * scale | app/src/utils/fontService.ts | opentype.js uses font coordinate system (Y-up) while canvas uses screen coordinates (Y-down). Apply `ascender * scale - font_y` to all Y values in path data. Without this, text renders upside-down. |\n| P011 | Letter spacing requires manual per-character glyph positioning | app/src/utils/fontService.ts | opentype.js getPath() doesn't support letter spacing. Must iterate characters, get individual glyph paths, accumulate x-advance + spacing per character, and compose the final SVG d-attribute manually. |\n| P012 | Adding new CanvasObject types requires exhaustive switch updates in 6 files | app/src/types/canvas.ts, KonvaStage, CanvasToolbar, ObjectPanel, ShapeProperties, AlignmentBar | TypeScript noFallthroughCasesInSwitch enforces exhaustive handling. When adding a new type to the CanvasObject union, all switch statements across these 6 files must be updated or compilation fails. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them. Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003). All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n| L007 | Docker build context must be project root, not engine/ | Dockerfile.engine uses `COPY engine/...` paths relative to project root | Always build with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` from project root | Docker |\n| L008 | Engine container has dual health endpoints | /health on root (main.py) and /engine/health on router (routes.py) both exist | Use /engine/health for Docker HEALTHCHECK and external probes for namespace consistency | engine API, Docker |\n| L009 | useCallback-based triggerTrace caused infinite re-render loops | Object params create new references each render, retriggering useEffect even when values are unchanged | Restructure hook to use single useEffect with JSON.stringify(params) in dependency array instead of useCallback-based approach | app hooks, React |\n| L010 | jest-canvas-mock crashes in Vitest with \"ReferenceError: jest is not defined\" | jest-canvas-mock internally calls jest.fn() in createImageBitmap.js — Jest globals don't exist in Vitest | Use vitest-canvas-mock (a Vitest-compatible fork) instead. Import it in test-setup.ts. | app tests, canvas |\n\n---\n\n# {{scope}} — Research\n\n**Date:** {{date}}\n\n\n\n## Summary\n\n{{summary — 2-3 paragraphs with primary recommendation}}\n\n## Recommendation\n\n{{whatApproachToTake_AND_why}}\n\n## Implementation Landscape\n\n\n\n### Key Files\n\n- `{{filePath}}` — {{whatItDoesAndHowItRelates}}\n- `{{filePath}}` — {{whatNeedsToChange}}\n\n### Build Order\n\n{{whatToProveOrBuildFirst_AND_why — whatUnblocksDownstreamWork}}\n\n### Verification Approach\n\n{{howToConfirmTheSliceWorks — commands, tests, observable behaviors}}\n\n\n\n## Don't Hand-Roll\n\n\n\n| Problem | Existing Solution | Why Use It |\n|---------|------------------|------------|\n| {{problem}} | {{solution}} | {{why}} |\n\n## Constraints\n\n\n\n- {{hardConstraintFromCodebaseOrRuntime}}\n- {{constraintFromDependencies}}\n\n## Common Pitfalls\n\n\n\n- **{{pitfall}}** — {{howToAvoid}}\n- **{{pitfall}}** — {{howToAvoid}}\n\n## Open Risks\n\n\n\n- {{riskThatCouldSurfaceDuringExecution}}\n\n## Skills Discovered\n\n\n\n| Technology | Skill | Status |\n|------------|-------|--------|\n| {{technology}} | {{owner/repo@skill}} | {{installed / available / none found}} |\n\n## Sources\n\n\n\n- {{whatWasLearned}} (source: [{{title}}]({{url}}))\n\n### Output Template: Research\nSource: `templates/research.md`\n\n### Dependency Slice Summaries\n\nPay particular attention to **Forward Intelligence** sections — they contain hard-won knowledge about what's fragile, what assumptions changed, and what to watch out for.\n\n- (no dependencies)\n\n## Your Role in the Pipeline\n\nYou are the scout. After you finish, a **planner agent** reads your output in a fresh context with no memory of your exploration. It uses your findings to decompose this slice into executable tasks — deciding what files change, what order to build things, how to verify the work. Then **executor agents** build each task in isolated context windows.\n\nWrite for the planner, not for a human. The planner needs:\n- **What files exist and what they do** — so it can scope tasks to specific files\n- **Where the natural seams are** — where work divides into independent units\n- **What to build or prove first** — what's riskiest, what unblocks everything else\n- **How to verify the result** — what commands, tests, or checks confirm the slice works\n\nIf the research doc is vague, the planner will waste its context re-exploring code you already read. If it's precise, the planner can decompose immediately.\n\n## Calibrate Depth\n\nRead the slice title, the roadmap excerpt, and any milestone research above. Ask: does this slice involve unfamiliar technology, risky integration, novel architecture, or ambiguous requirements? Or is it straightforward application of known patterns to known code?\n\n- **Deep research** — new technology, unfamiliar APIs, risky integration, multiple viable approaches, or ambiguous scope. Explore broadly, look up docs, check libraries, investigate constraints. Write all template sections. This is the default when you're genuinely uncertain.\n- **Targeted research** — known technology but new to this codebase, or moderately complex integration. Explore the relevant code, check one or two libraries, identify constraints. Omit Don't Hand-Roll and Sources if nothing applies.\n- **Light research** — well-understood work using established patterns already in the codebase (wiring up existing APIs, adding standard UI components, CRUD operations, configuration changes). Read the relevant files to confirm the pattern, note any constraints, write Summary + Recommendation + Implementation Landscape. Skip the rest. A light research doc can be 15-20 lines. Don't manufacture pitfalls or risks for work that doesn't have them.\n\nAn honest \"this is straightforward, here's the pattern to follow\" is more valuable than invented complexity.\n\n## Steps\n\nResearch what this slice needs. Narrate key findings and surprises as you go — what exists, what's missing, what constrains the approach.\n0. If `REQUIREMENTS.md` was preloaded above, identify which Active requirements this slice owns or supports. Research should target these requirements — surfacing risks, unknowns, and implementation constraints that could affect whether the slice actually delivers them.\n1. Reference specific rules from loaded skills in your findings where they inform the implementation approach.\n2. **Skill Discovery (suggest):**\n Identify the key technologies, frameworks, and services this work depends on (e.g. Stripe, Clerk, Supabase, JUCE, SwiftUI).\n For each, check if a professional agent skill already exists:\n - First check `` in your system prompt — a skill may already be installed.\n - For technologies without an installed skill, run: `npx skills find \"\"`\n - Only consider skills that are **directly relevant** to core technologies — not tangentially related.\n - Evaluate results by install count and relevance to the actual work.\n - Note promising skills in your research output with their install commands, but do NOT install them.\n - The user will decide which to install.\n3. Explore relevant code for this slice's scope. For targeted exploration, use `rg`, `find`, and reads. For broad or unfamiliar subsystems, use `scout` to map the relevant area first.\n4. Use `resolve_library` / `get_library_docs` for unfamiliar libraries — skip this for libraries already used in the codebase\n5. **Web search budget:** You have a limited budget of web searches (max ~15 per session). Use them strategically — prefer `resolve_library` / `get_library_docs` for library documentation. Do NOT repeat the same or similar queries. If a search didn't find what you need, rephrase once or move on. Target 3-5 total web searches for a typical research unit.\n6. Use the **Research** output template from the inlined context above — include only sections that have real content. The template is already inlined above; do NOT attempt to read any template file from disk (there is no `templates/SLICE-RESEARCH.md` — the correct template is already present in this prompt).\n7. Call `gsd_summary_save` with `milestone_id: M003`, `slice_id: S01`, `artifact_type: \"RESEARCH\"`, and the full research markdown as `content` — the tool computes the file path and persists to both DB and disk.\n\nThe slice directory already exists at `.gsd/milestones/M003/slices/S01/`.

The core challenge is converting the in-memory Konva canvas state (pixel-based objects) into downloadable DXF/SVG/PNG files at real-world scale. The engine already has a working DXF generator (`engine/output/dxf.py`) that produces AC1015 LWPOLYLINE entities from `PostProcessResult`, but it operates on engine-traced SVG paths — not on arbitrary canvas objects (shapes, text, images). The export flow must bridge this gap.\n\nThe main risks are: (1) DXF scale accuracy — converting from 96 PPI screen pixels to real-world inches/mm, (2) text-to-paths enforcement before export (text objects can't be represented in DXF), and (3) composing multiple canvas object types (shapes, images, text-as-paths) into a single coherent DXF file with proper layering. The engine's existing DXF generator is a good foundation but needs extension to accept layer assignments and unit configuration.\n\nThe frontend work is substantial: a new Export view with format selection, layer assignment UI, pre-export validation warnings, and download triggers. Canvas state must be lifted from DesignCanvas to App.tsx so it can be shared with the Export view.\n\n## Recommendation\n\n**Build client-side SVG composition + server-side DXF generation.** The frontend composes all canvas objects into a single SVG document (with text already converted to paths), sends it to the engine's existing `/engine/simplify` endpoint with `output_format=dxf`, and receives the DXF file. For SVG export, the composed SVG is downloaded directly. For PNG, use Konva's built-in `stage.toDataURL()`.\n\nThis avoids duplicating geometry handling in the frontend and reuses the engine's battle-tested DXF generator + postprocessing pipeline. The engine's `generate_dxf()` needs a small extension: accept unit configuration (`$INSUNITS`) and a scale factor so coordinates map to real-world dimensions.\n\n## Implementation Landscape\n\n### Key Files\n\n**Frontend (app/src/):**\n- `App.tsx` — Currently owns `view` state and `svgResult`. Must be extended to receive canvas state from View 2 and pass it to View 3. The `useCanvasState` hook currently lives inside `DesignCanvas.tsx` — it needs to be lifted to `App.tsx` or its state passed via a callback.\n- `views/DesignCanvas.tsx` — View 2 container. Needs an \"Export\" button that triggers navigation to View 3 with canvas state. Currently has no `onExport` / `onNavigateToExport` prop.\n- `views/ExportView.tsx` — **New file.** The Export view. Shows format selector (DXF/SVG/PNG), pre-export validation panel (warnings for unconverted text, open paths), layer assignment (for DXF), unit selection (inches/mm), and download button.\n- `utils/exportService.ts` — **New file.** Core export logic: (1) compose canvas objects into SVG string, (2) call engine API for DXF conversion, (3) trigger downloads. Pure functions, no React.\n- `utils/artboardShapes.ts` — Has `toPx()` and `fromPx()` converters (96 PPI). The export service uses `fromPx()` to convert pixel coords back to real-world units.\n- `api/engine.ts` — Needs a new function to call `/engine/simplify` or `/engine/trace` with `output_format=dxf` and receive binary DXF bytes (not JSON).\n- `types/canvas.ts` — `CanvasState`, `CanvasObject`, `ArtboardConfig` types. No changes needed.\n- `types/engine.ts` — May need a DXF response type (binary blob, not JSON).\n- `hooks/useCanvasState.ts` — No changes to the hook itself, but its instantiation point moves.\n\n**Engine (engine/):**\n- `output/dxf.py` — `generate_dxf()` needs extension: accept `units` param ('inches'|'mm'), set `$INSUNITS` header (1 for inches, 4 for mm), accept optional `scale_factor` to convert pixel coords to real-world coords, accept optional `layer_map` to assign paths to named DXF layers instead of just \"0\"/\"ISLANDS\".\n- `api/routes.py` — `_format_response()` and `/engine/simplify` already support `output_format=dxf`. The DXF binary response path works (tested in M001). May need to pass unit/scale params through to `generate_dxf()`.\n- `pipeline/postprocess.py` — `PostProcessResult` and `PathInfo` are the intermediate representation consumed by `generate_dxf()`. No changes needed — the frontend composes SVG, the engine parses it.\n\n### Build Order\n\n1. **Engine DXF unit/scale support** (lowest risk, unblocks everything) — Extend `generate_dxf()` to accept `units` and `scale_factor` params. Set `$INSUNITS` and `$MEASUREMENT` DXF headers. Apply scale_factor to all coordinates. Add `units` and `scale_factor` as optional Form params to `/engine/simplify`. Add tests. This is the critical correctness piece for R020.\n\n2. **Canvas state lifting** — Move `useCanvasState` instantiation from `DesignCanvas.tsx` to `App.tsx`. Pass state + actions as props to DesignCanvas. Add `onExport` callback prop to DesignCanvas that triggers view transition to 'export'. This is mechanical refactoring but touches many prop types.\n\n3. **Export service (SVG composition)** — Build `utils/exportService.ts` with `composeCanvasSVG(objects, artboard)` that renders all visible canvas objects into an SVG string. Text objects → error (must be converted first). Image objects → inline `` or re-embedded SVG path data. Shape objects → SVG primitives. Coordinate space: use `fromPx()` to convert to real-world units in the SVG viewBox.\n\n4. **Pre-export validation** — Build validation logic: check for unconverted text objects, check for open paths (from trace metadata), check artboard is set. Return structured warnings/errors.\n\n5. **Export view UI** — Build `ExportView.tsx`: format selector, validation panel, layer assignment (DXF only), download button. Wire to export service.\n\n6. **DXF API client + download** — Extend `api/engine.ts` with a function that POSTs composed SVG to `/engine/simplify?output_format=dxf` and returns a Blob for download. Handle the binary response (not JSON).\n\n7. **PNG export** — Use Konva's `stage.toDataURL({ pixelRatio: 2 })` for PNG export. This is trivial since Konva has built-in support.\n\n### Verification Approach\n\n1. **Engine DXF scale test**: Create a PostProcessResult with known pixel coordinates (e.g., a 384×576 pixel rectangle = 4×6 inches at 96 PPI). Generate DXF with `scale_factor=1/96` and `units='inches'`. Read back with ezdxf, verify polyline coordinates are 0-4 × 0-6 and `$INSUNITS` is 1.\n\n2. **SVG composition test**: Unit test `composeCanvasSVG()` with a known set of canvas objects (rect + image + circle). Verify the output SVG contains correct elements with proper coordinates.\n\n3. **Pre-export validation test**: Unit test validation catches unconverted text objects, reports them as blocking errors.\n\n4. **End-to-end manual test**: Design a sign with text + imported vector in View 2, navigate to View 3, export as DXF, open in Inkscape — verify correct geometry and scale. This matches the milestone's \"After this\" demo criteria.\n\n5. **PNG export test**: Export PNG, verify image dimensions match artboard at expected pixel ratio.\n\n6. **TypeScript compilation**: `tsc -b` passes with no errors after all changes.\n\n## Don't Hand-Roll\n\n| Problem | Existing Solution | Why Use It |\n|---------|------------------|------------|\n| DXF file generation | `ezdxf` (already in engine deps) | Battle-tested DXF library with AC1015+ support, layer management, unit headers. Already used in `engine/output/dxf.py`. |\n| PNG export from canvas | Konva.js `stage.toDataURL()` | Built-in Konva method. Returns data URL or triggers blob download. No need for html2canvas or other libraries. |\n| SVG path parsing for DXF | Engine `postprocess_svg()` pipeline | Already parses SVG paths into `PathInfo` coordinates consumed by `generate_dxf()`. Don't duplicate this in the frontend. |\n| Pixel ↔ real-world unit conversion | `artboardShapes.ts` `toPx()` / `fromPx()` | Already implements 96 PPI conversion with inches/mm support. |\n| File download trigger | Browser `URL.createObjectURL()` + hidden `` click | Standard browser download pattern. No library needed. |\n\n## Constraints\n\n- **Engine DXF generator only accepts `PostProcessResult`** — the frontend can't send arbitrary canvas objects to the engine for DXF conversion. It must first compose them into SVG, then send the SVG through `/engine/simplify` which runs `postprocess_svg()` → `generate_dxf()`.\n- **Text objects cannot be represented in DXF** — text must be converted to paths (via the existing \"Convert to Paths\" feature in ShapeProperties) before export. The export view must enforce this as a blocking validation error.\n- **Image objects with raster sources (PNG/JPG) cannot go into DXF** — only vector image objects (SVG blob URLs from imported traces or converted text) contain path data extractable to DXF. Raster images would need to be re-traced. The validation should warn about this.\n- **The `/engine/simplify` endpoint returns DXF as raw bytes with `Content-Disposition: attachment`** — the frontend API client must handle `response.blob()` instead of `response.json()` for DXF format.\n- **Konva.js `toDataURL()` requires the stage to be rendered** — PNG export must happen from View 2 (where the stage exists) or the stage must be re-rendered offscreen in View 3. Simpler: trigger PNG download from View 2 before navigating, or keep the stage mounted.\n- **P012 applies**: Adding any new canvas object type would require updates in 6 files. This slice doesn't add new types but the export service must handle all 6 existing types exhaustively.\n- **96 PPI is the fixed conversion factor** — `artboardShapes.ts` defines `PPI = 96`. All pixel-to-real-world conversions use this constant. DXF scale_factor = `1/96` for inches, `25.4/96` for mm.\n\n## Common Pitfalls\n\n- **SVG composition coordinate space mismatch** — Canvas objects use pixel coordinates relative to the artboard origin. The composed SVG must use the same coordinate space. The `viewBox` should match the artboard dimensions in pixels, and `width`/`height` attributes should be in real-world units for scale-correct SVG export.\n- **DXF Y-axis inversion** — DXF uses a standard cartesian coordinate system (Y-up). SVG/Canvas use Y-down. The engine's `generate_dxf()` currently does NOT flip Y coordinates. For laser cutting, this may or may not matter (LightBurn handles it). But verify: if the engine's PostProcessResult coords come from SVG (Y-down), the DXF should either flip them or document the convention. Check existing tests.\n- **Binary response handling in fetch API** — The existing `simplifyVector()` in `api/engine.ts` uses `res.json()` which fails for DXF binary responses. Need a separate code path: if `output_format=dxf`, use `res.blob()`.\n- **Blob URL cleanup** — Composed SVG blob URLs and download blob URLs must be revoked with `URL.revokeObjectURL()` after use to prevent memory leaks.\n- **Konva stage reference for PNG export** — The `stageRef` is currently owned by DesignCanvas. If PNG export happens from View 3, the stage isn't mounted. Options: (a) export PNG before leaving View 2, (b) render an offscreen Konva stage in View 3, (c) keep View 2 mounted but hidden. Option (a) is simplest.\n\n## Open Risks\n\n- **DXF scale verification requires external tool validation** — The milestone \"After this\" requires opening DXF in Inkscape/LightBurn with correct geometry. Automated tests can verify coordinates via ezdxf, but true validation needs a human opening the file. The automated test should at least verify that a 4-inch artboard produces DXF coordinates spanning 0-4 in the inch unit system.\n- **Complex SVG composition for image objects** — Image objects sourced from engine traces contain complex SVG path data (compound paths with fill-rule=\"evenodd\"). Re-embedding these into a composed SVG document requires careful namespace handling and may produce large SVG strings that slow down the engine's postprocessor.\n- **Konva stage.toDataURL() pixel ratio across devices** — Different devices have different `devicePixelRatio`. The PNG export should use a fixed `pixelRatio` (e.g., 2) for consistency, not the device default.\n\n## Skills Discovered\n\n| Technology | Skill | Status |\n|------------|-------|--------|\n| ezdxf | — | none found |\n| Konva.js | — | none found |\n| DXF export | — | none found |\n","milestone_id":"M003","slice_id":"S01"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":3508,"cacheRead":95906,"cacheWrite":189,"totalTokens":99604,"cost":{"input":0.000005,"output":0.0877,"cacheRead":0.047952999999999996,"cacheWrite":0.00118125,"total":0.13683925}},"stopReason":"toolUse","timestamp":1774505359958}} +{"type":"message","id":"f7964788","parentId":"d225d024","timestamp":"2026-03-26T06:10:44.207Z","message":{"role":"toolResult","toolCallId":"toolu_01TUJ4tf6dnarueTorCmQYrP","toolName":"gsd_summary_save","content":[{"type":"text","text":"Saved RESEARCH artifact to milestones/M003/slices/S01/S01-RESEARCH.md"}],"details":{"operation":"save_summary","path":"milestones/M003/slices/S01/S01-RESEARCH.md","artifact_type":"RESEARCH"},"isError":false,"timestamp":1774505444205}} +{"type":"message","id":"f1d188e9","parentId":"f7964788","timestamp":"2026-03-26T06:10:49.067Z","message":{"role":"assistant","content":[{"type":"text","text":"Slice S01 researched."}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":11,"cacheRead":96095,"cacheWrite":3546,"totalTokens":99653,"cost":{"input":0.000005,"output":0.000275,"cacheRead":0.0480475,"cacheWrite":0.0221625,"total":0.07049}},"stopReason":"stop","timestamp":1774505444206}} diff --git a/.gsd/activity/040-plan-slice-M003-S01.jsonl b/.gsd/activity/040-plan-slice-M003-S01.jsonl new file mode 100644 index 0000000..14a83ca --- /dev/null +++ b/.gsd/activity/040-plan-slice-M003-S01.jsonl @@ -0,0 +1,64 @@ +{"type":"thinking_level_change","id":"d614772f","parentId":null,"timestamp":"2026-03-26T06:10:49.355Z","thinkingLevel":"off"} +{"type":"custom_message","customType":"gsd-auto","content":"You are executing GSD auto-mode.\n\n## Working Directory\n\nYour working directory is `/home/aux/development/xpltdco/kerf-engine`.

If `REQUIREMENTS.md` was preloaded above, identify which Active requirements the roadmap says this slice owns or supports.

Define slice-level verification — the objective stopping condition for this slice:\n - For non-trivial slices: plan actual test files with real assertions. Name the files.\n - For simple slices: executable commands or script assertions are fine.\n - If the project is non-trivial and has no test framework, the first task should set one up.\n - If this slice establishes a boundary contract, verification must exercise that contract.\n4. **For non-trivial slices only** — plan observability, proof level, and integration closure:\n - Include `Observability / Diagnostics` for backend, integration, async, stateful, or UI slices where failure diagnosis matters.\n - Fill `Proof Level` and `Integration Closure` when the slice crosses runtime boundaries or has meaningful integration concerns.\n - **Omit these sections entirely for simple slices** where they would all be \"none\" or trivially obvious.\n5. Decompose the slice into tasks, each fitting one context window. Each task needs:\n - a concrete, action-oriented title\n - the inline task entry fields defined in the plan.md template (Why / Files / Do / Verify / Done when)\n - a matching task plan file with description, steps, must-haves, verification, inputs, and expected output\n - **Inputs and Expected Output must list concrete backtick-wrapped file paths** (e.g. `` `src/types.ts` ``).

The core challenge is converting the in-memory Konva canvas state (pixel-based objects) into downloadable DXF/SVG/PNG files at real-world scale. The engine already has a working DXF generator (`engine/output/dxf.py`) that produces AC1015 LWPOLYLINE entities from `PostProcessResult`, but it operates on engine-traced SVG paths — not on arbitrary canvas objects (shapes, text, images). The export flow must bridge this gap.\n\nThe main risks are: (1) DXF scale accuracy — converting from 96 PPI screen pixels to real-world inches/mm, (2) text-to-paths enforcement before export (text objects can't be represented in DXF), and (3) composing multiple canvas object types (shapes, images, text-as-paths) into a single coherent DXF file with proper layering. The engine's existing DXF generator is a good foundation but needs extension to accept layer assignments and unit configuration.\n\nThe frontend work is substantial: a new Export view with format selection, layer assignment UI, pre-export validation warnings, and download triggers. Canvas state must be lifted from DesignCanvas to App.tsx so it can be shared with the Export view.\n\n## Recommendation\n\n**Build client-side SVG composition + server-side DXF generation.** The frontend composes all canvas objects into a single SVG document (with text already converted to paths), sends it to the engine's existing `/engine/simplify` endpoint with `output_format=dxf`, and receives the DXF file. For SVG export, the composed SVG is downloaded directly. For PNG, use Konva's built-in `stage.toDataURL()`.\n\nThis avoids duplicating geometry handling in the frontend and reuses the engine's battle-tested DXF generator + postprocessing pipeline. The engine's `generate_dxf()` needs a small extension: accept unit configuration (`$INSUNITS`) and a scale factor so coordinates map to real-world dimensions.\n\n## Implementation Landscape\n\n### Key Files\n\n**Frontend (app/src/):**\n- `App.tsx` — Currently owns `view` state and `svgResult`. Must be extended to receive canvas state from View 2 and pass it to View 3. The `useCanvasState` hook currently lives inside `DesignCanvas.tsx` — it needs to be lifted to `App.tsx` or its state passed via a callback.\n- `views/DesignCanvas.tsx` — View 2 container. Needs an \"Export\" button that triggers navigation to View 3 with canvas state. Currently has no `onExport` / `onNavigateToExport` prop.\n- `views/ExportView.tsx` — **New file.** The Export view. Shows format selector (DXF/SVG/PNG), pre-export validation panel (warnings for unconverted text, open paths), layer assignment (for DXF), unit selection (inches/mm), and download button.\n- `utils/exportService.ts` — **New file.** Core export logic: (1) compose canvas objects into SVG string, (2) call engine API for DXF conversion, (3) trigger downloads. Pure functions, no React.\n- `utils/artboardShapes.ts` — Has `toPx()` and `fromPx()` converters (96 PPI). The export service uses `fromPx()` to convert pixel coords back to real-world units.\n- `api/engine.ts` — Needs a new function to call `/engine/simplify` or `/engine/trace` with `output_format=dxf` and receive binary DXF bytes (not JSON).\n- `types/canvas.ts` — `CanvasState`, `CanvasObject`, `ArtboardConfig` types. No changes needed.\n- `types/engine.ts` — May need a DXF response type (binary blob, not JSON).\n- `hooks/useCanvasState.ts` — No changes to the hook itself, but its instantiation point moves.\n\n**Engine (engine/):**\n- `output/dxf.py` — `generate_dxf()` needs extension: accept `units` param ('inches'|'mm'), set `$INSUNITS` header (1 for inches, 4 for mm), accept optional `scale_factor` to convert pixel coords to real-world coords, accept optional `layer_map` to assign paths to named DXF layers instead of just \"0\"/\"ISLANDS\".\n- `api/routes.py` — `_format_response()` and `/engine/simplify` already support `output_format=dxf`. The DXF binary response path works (tested in M001). May need to pass unit/scale params through to `generate_dxf()`.\n- `pipeline/postprocess.py` — `PostProcessResult` and `PathInfo` are the intermediate representation consumed by `generate_dxf()`. No changes needed — the frontend composes SVG, the engine parses it.\n\n### Build Order\n\n1. **Engine DXF unit/scale support** (lowest risk, unblocks everything) — Extend `generate_dxf()` to accept `units` and `scale_factor` params. Set `$INSUNITS` and `$MEASUREMENT` DXF headers. Apply scale_factor to all coordinates. Add `units` and `scale_factor` as optional Form params to `/engine/simplify`. Add tests. This is the critical correctness piece for R020.\n\n2. **Canvas state lifting** — Move `useCanvasState` instantiation from `DesignCanvas.tsx` to `App.tsx`. Pass state + actions as props to DesignCanvas. Add `onExport` callback prop to DesignCanvas that triggers view transition to 'export'. This is mechanical refactoring but touches many prop types.\n\n3. **Export service (SVG composition)** — Build `utils/exportService.ts` with `composeCanvasSVG(objects, artboard)` that renders all visible canvas objects into an SVG string. Text objects → error (must be converted first). Image objects → inline `` or re-embedded SVG path data. Shape objects → SVG primitives. Coordinate space: use `fromPx()` to convert to real-world units in the SVG viewBox.\n\n4. **Pre-export validation** — Build validation logic: check for unconverted text objects, check for open paths (from trace metadata), check artboard is set. Return structured warnings/errors.\n\n5. **Export view UI** — Build `ExportView.tsx`: format selector, validation panel, layer assignment (DXF only), download button. Wire to export service.\n\n6. **DXF API client + download** — Extend `api/engine.ts` with a function that POSTs composed SVG to `/engine/simplify?output_format=dxf` and returns a Blob for download. Handle the binary response (not JSON).\n\n7. **PNG export** — Use Konva's `stage.toDataURL({ pixelRatio: 2 })` for PNG export. This is trivial since Konva has built-in support.\n\n### Verification Approach\n\n1. **Engine DXF scale test**: Create a PostProcessResult with known pixel coordinates (e.g., a 384×576 pixel rectangle = 4×6 inches at 96 PPI). Generate DXF with `scale_factor=1/96` and `units='inches'`. Read back with ezdxf, verify polyline coordinates are 0-4 × 0-6 and `$INSUNITS` is 1.\n\n2. **SVG composition test**: Unit test `composeCanvasSVG()` with a known set of canvas objects (rect + image + circle). Verify the output SVG contains correct elements with proper coordinates.\n\n3. **Pre-export validation test**: Unit test validation catches unconverted text objects, reports them as blocking errors.\n\n4. **End-to-end manual test**: Design a sign with text + imported vector in View 2, navigate to View 3, export as DXF, open in Inkscape — verify correct geometry and scale. This matches the milestone's \"After this\" demo criteria.\n\n5. **PNG export test**: Export PNG, verify image dimensions match artboard at expected pixel ratio.\n\n6. **TypeScript compilation**: `tsc -b` passes with no errors after all changes.\n\n## Don't Hand-Roll\n\n| Problem | Existing Solution | Why Use It |\n|---------|------------------|------------|\n| DXF file generation | `ezdxf` (already in engine deps) | Battle-tested DXF library with AC1015+ support, layer management, unit headers.

If PNG export happens from View 3, the stage isn't mounted. Options: (a) export PNG before leaving View 2, (b) render an offscreen Konva stage in View 3, (c) keep View 2 mounted but hidden. Option (a) is simplest.\n\n## Open Risks\n\n- **DXF scale verification requires external tool validation** — The milestone \"After this\" requires opening DXF in Inkscape/LightBurn with correct geometry. Automated tests can verify coordinates via ezdxf, but true validation needs a human opening the file. The automated test should at least verify that a 4-inch artboard produces DXF coordinates spanning 0-4 in the inch unit system.\n- **Complex SVG composition for image objects** — Image objects sourced from engine traces contain complex SVG path data (compound paths with fill-rule=\"evenodd\"). Re-embedding these into a composed SVG document requires careful namespace handling and may produce large SVG strings that slow down the engine's postprocessor.\n- **Konva stage.toDataURL() pixel ratio across devices** — Different devices have different `devicePixelRatio`. The PNG export should use a fixed `pixelRatio` (e.g., 2) for consistency, not the device default.\n\n## Skills Discovered\n\n| Technology | Skill | Status |\n|------------|-------|--------|\n| ezdxf | — | none found |\n| Konva.js | — | none found |\n| DXF export | — | none found |\n\n---\n\n### Decisions\nSource: `.gsd/DECISIONS.md`\n\n# Decisions Register\n\n\n\n| # | When | Scope | Decision | Choice | Rationale | Revisable? | Made By |\n|---|------|-------|----------|--------|-----------|------------|---------|\n| D001 | | architecture | Engine/App architectural relationship | Engine is standalone module, App is a consumer. Zero coupling — App calls Engine only via HTTP API. | Engine is proprietary IP that must be embeddable into future applications independently. Clean input/output contracts enable this. | No | human |\n| D002 | | architecture | Build order and gating strategy | Build Engine first (M001), then App canvas (M002), then Export+Deploy+Embed (M003). Human checkpoints gate each transition. | Brief explicitly mandates: validate engine output quality before building canvas UI, validate canvas before export/deploy. Engine is the hardest and most valuable piece. | No | human |\n| D003 | | engine | Post-processing replaces regex metadata extraction | postprocess_svg() pipeline replaces old _extract_svg_metadata() regex approach; all SVG paths are parsed into structured PathInfo objects with coordinates, area, island status | Structured path data is needed for DXF/JSON output generation, RDP simplification, and island detection. XML parsing is now necessary since we need actual coordinate data, not just counts. This supersedes D003's regex approach. | No | agent |\n| D004 | | architecture | Engine Docker image build strategy | Multi-stage build: builder stage compiles pypotrace with build-essential/libagg-dev/libpotrace-dev, runtime stage uses python:3.11-slim with only runtime libs (libpotrace0, libagg2, curl). Only engine source is copied — no App code. | Multi-stage keeps the runtime image small by excluding build tools. Copying only engine source enforces the Engine/App separation (D001). curl is included for Docker HEALTHCHECK. | Yes | agent |\n| D005 | | architecture | Frontend technology stack for Kerf App | Vite + React + TypeScript with plain CSS modules, Vitest for testing, raw fetch + FormData for engine API calls, no UI framework for V1 | Minimal dependency surface for a tool that needs fast iteration. The engine API uses multipart/form-data which works naturally with native fetch + FormData. CSS modules avoid global style conflicts without adding a framework. Vitest integrates natively with Vite's transform pipeline. No UI library needed — the app has a focused interface with ~8 components. | Yes | agent |\n| D006 | | frontend | React hook params stabilization strategy for useDebouncedTrace | JSON.stringify params in useEffect deps array, single-effect architecture | useCallback-based triggerTrace with object params caused infinite re-render loops because React creates new object references each render. JSON.stringify converts params to a stable string for dependency comparison, eliminating the need for callers to useMemo their params objects. Simpler API surface and no re-render bugs. | Yes | agent |\n| D007 | | architecture | Canvas object type system design | Discriminated union on `type` field: 'rect' \\| 'circle' \\| 'ellipse' \\| 'line' \\| 'image'. All objects share BaseCanvasObject (id, name, x, y, visible, locked, stroke, fill, opacity). Type-specific fields via intersection types. | TypeScript discriminated unions enable exhaustive type narrowing in switch/if statements, catching missing cases at compile time. Shared base keeps CRUD operations generic while type-specific panels (ShapeProperties) safely narrow to access unique fields. 'text' type will be added in S03. | Yes | agent |\n| D008 | | frontend | opentype.js integration strategy for font loading and text-to-path conversion | opentype.js v1.3.4 with dynamic import(), local type declarations, per-character glyph positioning for letter spacing, and Y-axis flip (canvas_y = ascender - font_y * scale) for canvas-compatible SVG path coordinates | opentype.js has no @types package, so local declarations are needed. The library's getPath() doesn't support letter spacing natively — manual per-character positioning with x-advance accumulation is required. Font coordinate system is Y-up while canvas is Y-down, requiring the ascender-based flip formula. Dynamic import() avoids bundling issues with the library's CommonJS/ESM dual packaging. | Yes | agent |\n| D009 | | frontend | Text-to-paths conversion strategy | Convert-to-paths uses a single onConvertToPath(textObjectId, imageObject) callback that generates an SVG Blob URL and creates an ImageObject replacement, reusing the existing image rendering pipeline | Reusing the ImageObject type and its existing Konva rendering avoids adding a new 'path' object type. A single callback keeps the prop interface simpler than separate onAddObject + onRemoveObject and makes the replacement atomic. The SVG Blob URL contains the path data with fill/stroke matching the original text object. | Yes | agent |\n\n---\n\n### Project Knowledge\nSource: `.gsd/KNOWLEDGE.md`\n\n# Project Knowledge\n\nAppend-only register of project-specific rules, patterns, and lessons learned.\nAgents read this before every unit. Add entries when you discover something worth remembering.\n\n## Rules\n\n| # | Scope | Rule | Why | Added |\n|---|-------|------|-----|-------|\n\n## Patterns\n\n| # | Pattern | Where | Notes |\n|---|---------|-------|-------|\n| P001 | Test images generated programmatically via numpy | engine/tests/ | No fixture image files checked in. Tests create shapes (rectangles, circles) with numpy + cv2. Continue this pattern in S02/S03. |\n| P002 | Tests must use .venv/bin/python -m pytest | engine/ | No system-wide `python` on PATH. Bare `python -m pytest` fails with exit 127. Always use the venv binary. |\n| P003 | PostProcessResult is the universal intermediate representation | engine/pipeline/postprocess.py → engine/output/ | All output generators (DXF, JSON, SVG) consume PostProcessResult. Never generate output directly from raw SVG strings. |\n| P004 | _format_response() for consistent multi-format API responses | engine/api/routes.py | DXF returns binary Response with X-Kerf-Metadata header; SVG/JSON return JSON envelopes. Use _format_response() for both /engine/trace and /engine/simplify. |\n| P005 | Preset-driven pipeline: resolve_params() merges preset → user | engine/presets/loader.py, engine/api/routes.py | Presets define defaults for all pipeline stages. User params override. Mode comes from preset unless user explicitly sets it. |\n| P006 | JSON.stringify for React hook dependency stabilization | app/src/hooks/useDebouncedTrace.ts | Object params in useEffect deps cause infinite loops (new ref each render). Stringify the params object and use the string in the deps array. Avoids requiring callers to useMemo. |\n| P007 | Vite dev proxy for engine API calls | app/vite.config.ts | `/engine/*` requests proxy to `http://localhost:8000`. API client uses relative URLs (`/engine/presets`). No CORS issues in dev because same-origin via proxy. |\n| P008 | CSS modules for views, global App.css for shared component styles | app/src/views/*.module.css, app/src/App.css | View-specific layout in CSS modules avoids conflicts. Shared styles (upload zone, preset cards, buttons) in App.css for cross-component reuse. |\n| P009 | opentype.js needs dynamic import() and local type declarations | app/src/utils/fontService.ts | No @types/opentype.js package exists. Use `const opentype = await import('opentype.js')` with `type OpentypeFont = any` for the Font object. Variable .ttf fonts work fine for glyph extraction. |\n| P010 | Font Y-axis flip: canvas_y = ascender - font_y * scale | app/src/utils/fontService.ts | opentype.js uses font coordinate system (Y-up) while canvas uses screen coordinates (Y-down). Apply `ascender * scale - font_y` to all Y values in path data. Without this, text renders upside-down. |\n| P011 | Letter spacing requires manual per-character glyph positioning | app/src/utils/fontService.ts | opentype.js getPath() doesn't support letter spacing. Must iterate characters, get individual glyph paths, accumulate x-advance + spacing per character, and compose the final SVG d-attribute manually. |\n| P012 | Adding new CanvasObject types requires exhaustive switch updates in 6 files | app/src/types/canvas.ts, KonvaStage, CanvasToolbar, ObjectPanel, ShapeProperties, AlignmentBar | TypeScript noFallthroughCasesInSwitch enforces exhaustive handling. When adding a new type to the CanvasObject union, all switch statements across these 6 files must be updated or compilation fails. |\n\n## Lessons Learned\n\n| # | What Happened | Root Cause | Fix | Scope |\n|---|--------------|------------|-----|-------|\n| L001 | pypotrace fails to build from pip | Requires system packages: `libpotrace-dev`, `libagg-dev`, `pkg-config` | `apt-get install -y libpotrace-dev libagg-dev pkg-config` before `pip install pypotrace` | engine build, Docker |\n| L002 | VTracer Python bindings work directly — no subprocess needed | vtracer pip package exposes `convert_raw_image_to_svg()` that accepts PNG bytes | Use `vtracer.convert_raw_image_to_svg(png_bytes, img_format=\"png\", ...)` | engine vectorize |\n| L003 | pypotrace Bitmap requires uint32 data | Passing other dtypes (uint8, float) can cause segfaults | Always cast: `(img > 0).astype(np.uint32)` before `potrace.Bitmap(data)` | engine vectorize |\n| L004 | ezdxf emits pyparsing deprecation warnings in tests | ezdxf uses deprecated pyparsing method names (`addParseAction`, `oneOf`, etc.) | These are harmless library warnings — don't try to fix them. Filter with `pytest -W ignore::DeprecationWarning` if noisy. | engine tests |\n| L005 | DXF output format needs binary response, not JSON envelope | DXF files are binary/text data not suitable for JSON embedding | Use FastAPI `Response(content=bytes, media_type=\"application/dxf\")` with metadata in `X-Kerf-Metadata` header | engine API |\n| L006 | postprocess_svg() fully parses SVG paths into coordinates | XML parsing + path d-attribute parsing gives structured PathInfo objects | This replaces the old regex-based SVG metadata extraction (D003). All output generators (DXF, JSON, SVG) consume PostProcessResult. | engine pipeline |\n| L007 | Docker build context must be project root, not engine/ | Dockerfile.engine uses `COPY engine/...` paths relative to project root | Always build with `docker build -f docker/Dockerfile.engine -t kerf-engine:dev .` from project root | Docker |\n| L008 | Engine container has dual health endpoints | /health on root (main.py) and /engine/health on router (routes.py) both exist | Use /engine/health for Docker HEALTHCHECK and external probes for namespace consistency | engine API, Docker |\n| L009 | useCallback-based triggerTrace caused infinite re-render loops | Object params create new references each render, retriggering useEffect even when values are unchanged | Restructure hook to use single useEffect with JSON.stringify(params) in dependency array instead of useCallback-based approach | app hooks, React |\n| L010 | jest-canvas-mock crashes in Vitest with \"ReferenceError: jest is not defined\" | jest-canvas-mock internally calls jest.fn() in createImageBitmap.js — Jest globals don't exist in Vitest | Use vitest-canvas-mock (a Vitest-compatible fork) instead. Import it in test-setup.ts. | app tests, canvas |\n\n[...truncated 2 sections]\n\n### Dependency Slice Summaries\n\nPay particular attention to **Forward Intelligence** sections — they contain hard-won knowledge about what's fragile, what assumptions changed, and what this slice should watch out for.\n\n- (no dependencies)\n\n## Your Role in the Pipeline\n\nYou have full tool access. Before decomposing, explore the relevant code to ground your plan in reality.\n\n### Verify Roadmap Assumptions\n\nCheck prior slice summaries (inlined above as dependency summaries, if present). If prior slices discovered constraints, changed approaches, or flagged fragility, adjust your plan accordingly. The roadmap description may be stale — verify it against the current codebase state.\n\n### Explore Slice Scope\n\nRead the code files relevant to this slice. Confirm the roadmap's description of what exists, what needs to change, and what boundaries apply. Use `rg`, `find`, and targeted reads.\n\n### Source Files\n\n- **Project**: `.gsd/PROJECT.md`\n- **Decisions**: `.gsd/DECISIONS.md`\n- **Roadmap**: `.gsd/milestones/M003/M003-ROADMAP.md`\n- **Slice Research**: `.gsd/milestones/M003/slices/S01/S01-RESEARCH.md`\n\nIf slice research exists (inlined above), trust those findings and skip redundant exploration.\n\nAfter you finish, **executor agents** implement each task in isolated fresh context windows. They see only their task plan, the slice plan excerpt (goal/demo/verification), and compressed summaries of prior tasks. They do not see the research doc, the roadmap, or REQUIREMENTS.md. Everything an executor needs must be in the task plan itself — file paths, specific steps, expected inputs and outputs.\n\nNarrate your decomposition reasoning — why you're grouping work this way, what risks are driving the order, what verification strategy you're choosing and why. Keep the narration proportional to the work — a simple slice doesn't need a long justification — but write in complete sentences, not planner shorthand.\n\n**Right-size the plan.** If the slice is simple enough to be 1 task, plan 1 task. Don't split into multiple tasks just because you can identify sub-steps. Don't fill in sections with \"None\" when the section doesn't apply — omit them entirely. The plan's job is to guide execution, not to fill a template.\n","display":false,"id":"55019385","parentId":"d614772f","timestamp":"2026-03-26T06:10:49.357Z"}

Now I have a complete picture. Let me reason through the decomposition.\n\n---\n\n**Decomposition Reasoning:**\n\nThis slice needs to deliver the complete Export flow (View 3) with DXF generation. The research document lays out a clear build order. Let me validate the key architectural decisions:\n\n1. **Engine DXF extension** — `generate_dxf()` currently takes only `PostProcessResult` with no unit/scale params. Need to add `units`, `scale_factor`, and `$INSUNITS`/`$MEASUREMENT` headers. The `/engine/simplify` endpoint needs these as optional params. This is the lowest-risk piece and unblocks everything else.\n\n2. **Canvas state lifting** — Currently `useCanvasState` is instantiated inside `DesignCanvas`. For the Export view to access canvas state, it needs to be lifted to `App.tsx`. This is mechanical refactoring.\n\n3. **Export service + Export view + API client** — The frontend needs: SVG composition from canvas objects, pre-export validation, DXF API call with binary response, and the Export view UI with format selection and download.\n\n4. **PNG export** — Trivial, uses Konva's built-in `stage.toDataURL()`.\n\nI'll organize this into **4 tasks** that follow the natural dependency chain:\n\n- **T01**: Engine DXF unit/scale extension + tests (backend, no frontend dependency)\n- **T02**: Canvas state lifting to App.tsx + Export navigation (mechanical refactoring, unblocks View 3)\n- **T03**: Export service (SVG composition, validation, DXF API client) + unit tests\n- **T04**: Export view UI + PNG export + end-to-end wiring\n\nThis is 4 tasks, each fits in a single context window, and they form a clean dependency chain where each task produces a concrete increment.\n\nNow let me persist the plan:"},{"type":"toolCall","id":"toolu_01VSGYaT8v61muqmMVuF8CXD","name":"gsd_plan_slice","arguments":{"goal":"Complete Export view (View 3) with DXF/SVG/PNG download.

All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M003/slices/S01/S01-PLAN.md`\n- Task plan source: `.gsd/milestones/M003/slices/S01/tasks/T01-PLAN.md`\n- Prior task summaries in this slice:\n- (no prior tasks)\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M003/slices/S01/tasks/T01-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M003/slices/S01/tasks/T01-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T01 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M003/slices/S01/S01-PLAN.md`\n**Goal:** Complete Export view (View 3) with DXF/SVG/PNG download.

This task lifts the hook instantiation to `App.tsx`, passes state + actions as props to `DesignCanvas`, and adds an `onExport` callback prop that triggers navigation to the 'export' view. The Export view placeholder in App.tsx is updated to receive canvas state props. DesignCanvas gets an 'Export' button in its toolbar area. All existing DesignCanvas functionality must remain unchanged — this is a mechanical prop-threading refactor.\n\nKey constraints:\n- `useCanvasState` hook itself is NOT modified — only where it's called changes\n- DesignCanvas receives `state`, `addObject`, `removeObject`, `updateObject`, `selectObjects`, `deselectAll`, `reorderObject`, `toggleVisibility`, `toggleLock`, `setArtboard`, `undo`, `redo`, `canUndo`, `canRedo` as props instead of calling the hook internally\n- The `traceMetadata` param to `useCanvasState()` comes from App.tsx's existing `traceMetadata` state\n- App.tsx passes a `stageRef` to DesignCanvas and receives it back so PNG export can work later\n- A `Ref` is created in App.tsx and passed to DesignCanvas for stage access from View 3\n - Estimate: 1.5h\n - Files: app/src/App.tsx, app/src/views/DesignCanvas.tsx\n - Verify: cd app && npx tsc -b --noEmit && npx vitest run\n- [ ] **T03: Build export service with SVG composition, validation, and DXF API client** — This task creates the core export logic as pure utility functions: (1) `composeCanvasSVG()` renders visible canvas objects into an SVG string with correct coordinate space and real-world unit dimensions, (2) `validateForExport()` checks for unconverted text objects (blocking error), raster-only images (warning), and missing artboard (blocking error), (3) `exportDxf()` in the API client POSTs composed SVG to `/engine/simplify?output_format=dxf` with `units` and `scale_factor` params and returns a Blob, (4) `triggerDownload()` creates a hidden anchor + blob URL to trigger browser download with proper cleanup.\n\nSVG composition details:\n- The SVG viewBox matches artboard dimensions in pixels\n- `width`/`height` attributes use real-world units (e.g., `width=\"4in\"` or `width=\"101.6mm\"`)\n- RectObject → ``, CircleObject → ``, EllipseObject → ``, LineObject → ``\n- ImageObject with SVG blob src → inline the SVG content (extract path data from blob URL)\n- ImageObject with raster src → skip (validation warns about this)\n- TextObject → error (validation blocks this — must be converted to paths first)\n- Objects with `visible: false` are skipped\n- All coordinates are in the artboard's pixel space (the engine handles conversion via scale_factor)\n\nDXF API client:\n- New function `exportAsDxf(svgContent: string, units: 'inches' | 'mm', scaleFactor: number, signal?: AbortSignal): Promise`\n- Uses FormData with file as Blob, output_format=dxf, units, scale_factor\n- Returns `response.blob()` not `response.json()`\n\nUnit tests cover: SVG composition with known objects produces correct SVG elements, validation catches text objects, validation warns on raster images, coordinate space is correct.\n - Estimate: 2h\n - Files: app/src/utils/exportService.ts, app/src/utils/__tests__/exportService.test.ts, app/src/api/engine.ts, app/src/api/__tests__/engine.test.ts\n - Verify: cd app && npx vitest run src/utils/__tests__/exportService.test.ts src/api/__tests__/engine.test.ts && npx tsc -b --noEmit\n- [ ] **T04: Build Export view UI with format selection, validation panel, and download wiring** — This task builds the ExportView component — the final piece that wires everything together. The view receives canvas state from App.tsx (lifted in T02) and uses the export service (built in T03) to compose SVG, validate, call the engine API, and trigger downloads.\n\nExportView layout:\n- Header with \"Export\" title and a \"← Back to Design\" button that navigates back to View 2\n- Format selector: three cards/buttons for DXF, SVG, PNG with descriptions\n- Unit selector (DXF/SVG only): inches or mm radio buttons, defaulting to the artboard's unit\n- Validation panel: shows blocking errors (red, disables export) and warnings (yellow, allows export). Runs `validateForExport()` on mount and when objects change\n- Canvas preview: a small thumbnail of the current design (use Konva `stage.toDataURL()` from the stageRef passed through App.tsx, captured before navigating to export view)\n- Download button: disabled when blocking errors exist; triggers the appropriate export flow\n\nExport flows by format:\n- **DXF**: Call `composeCanvasSVG()` → call `exportAsDxf()` with units and scale_factor (1/96 for inches, 25.4/96 for mm) → `triggerDownload()` with the returned blob and filename `export.dxf`\n- **SVG**: Call `composeCanvasSVG()` → create blob from SVG string → `triggerDownload()` with filename `export.svg`\n- **PNG**: Use the preview data URL (captured from Konva stage before navigating) or re-render. Since stageRef may not be mounted in View 3, capture PNG data URL before transitioning to export view and pass it as a prop. Convert data URL to blob → `triggerDownload()` with filename `export.png`\n\nPNG capture strategy: When user clicks 'Export' in View 2, capture `stageRef.current.toDataURL({ pixelRatio: 2 })` and store in App.tsx state, then navigate to export view. This avoids needing the Konva stage mounted in View 3.\n\nApp.tsx updates:\n- Add `pngDataUrl` state, set it in the onExport handler before view transition\n- Pass `pngDataUrl` to ExportView\n- Wire ExportView's onBack to navigate back to canvas view\n\nCSS: New `ExportView.module.css` with the view layout. Follow existing patterns from DesignCanvas.module.css and App.css.\n - Estimate: 2h\n - Files: app/src/views/ExportView.tsx, app/src/views/ExportView.module.css, app/src/App.tsx\n - Verify: cd app && npx tsc -b --noEmit && npx vitest run\n"}],"isError":false,"timestamp":1774505646419}} +{"type":"message","id":"6f412179","parentId":"cea84d68","timestamp":"2026-03-26T06:14:09.993Z","message":{"role":"assistant","content":[{"type":"text","text":"Now let me examine the existing source files that I'll be modifying."},{"type":"toolCall","id":"toolu_01E4zYazHQuBUdvkzDYjSD8h","name":"read","arguments":{"path":"engine/output/dxf.py"}},{"type":"toolCall","id":"toolu_01H12X7ySUAYayUMfPCfCYR6","name":"read","arguments":{"path":"engine/api/routes.py"}},{"type":"toolCall","id":"toolu_0113y3ytntw2SWKw99mrCqpG","name":"read","arguments":{"path":"engine/tests/test_output.py"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":157,"cacheRead":52777,"cacheWrite":2857,"totalTokens":55792,"cost":{"input":0.000005,"output":0.0039250000000000005,"cacheRead":0.0263885,"cacheWrite":0.01785625,"total":0.04817475}},"stopReason":"toolUse","timestamp":1774505646419}} +{"type":"message","id":"6a5dc374","parentId":"6f412179","timestamp":"2026-03-26T06:14:09.995Z","message":{"role":"toolResult","toolCallId":"toolu_01E4zYazHQuBUdvkzDYjSD8h","toolName":"read","content":[{"type":"text","text":"\"\"\"DXF output generator — AC1015+ DXF from PostProcessResult using ezdxf.\"\"\"\n\nfrom __future__ import annotations\n\nimport io\n\nimport ezdxf\n\nfrom pipeline.postprocess import PathInfo, PostProcessResult\n\n\ndef _add_path_to_msp(\n msp: ezdxf.layouts.BaseLayout,\n path: PathInfo,\n layer: str = \"0\",\n) -> None:\n \"\"\"Add a single PathInfo as an LWPOLYLINE entity to the modelspace.\n\n Closed paths get the LWPOLYLINE close flag set.\n Islands are placed on a separate \"ISLANDS\" layer for downstream CAM tools.\n \"\"\"\n coords = path.simplified_coords\n if len(coords) < 2:\n return\n\n target_layer = \"ISLANDS\" if path.is_island else layer\n\n # LWPOLYLINE uses (x, y[, start_width, end_width, bulge]) tuples\n points = [(x, y) for x, y in coords]\n\n # Remove duplicate close point if the polyline close flag handles it\n if path.is_closed and len(points) > 1 and points[0] == points[-1]:\n points = points[:-1]\n\n msp.add_lwpolyline(\n points,\n dxfattribs={\"layer\": target_layer},\n close=path.is_closed,\n )\n\n\ndef generate_dxf(result: PostProcessResult) -> bytes:\n \"\"\"Generate an AC1015 (AutoCAD R2000) DXF file from post-processed path data.\n\n Creates LWPOLYLINE entities from simplified coordinate data.

When `units` is provided, the DXF header variables `$INSUNITS` and `$MEASUREMENT` are set to the correct codes (inches → 1/0, mm → 4/1). The `scale_factor` is applied to all (x, y) coordinates inside `_add_path_to_msp()`. The `layer_map` allows assigning specific path indices to named DXF layers, with fallback to the existing island/default-layer logic.\n\nOn the API side, the `/engine/simplify` endpoint in `engine/api/routes.py` now accepts optional `units` (str) and `scale_factor` (float, default 1.0) Form params. These are validated (units must be \"inches\" or \"mm\" if provided) and passed through `_format_response()` to `generate_dxf()`. The `_format_response()` helper was extended with keyword-only `units` and `scale_factor` args, keeping full backward compatibility — existing callers (the `/engine/trace` endpoint) continue to work without changes.\n\nAdded 11 new tests in `TestDXFUnitsAndScale` covering: scale conversion to inches (384×576 px → 4×6 at 1/96), scale conversion to mm (→ 101.6×152.4 at 25.4/96), $INSUNITS header for inches/mm, $MEASUREMENT header for imperial/metric, no-units default behavior, default scale_factor passthrough, layer_map path assignment, island layer preservation with layer_map, and a combined test exercising all three features together.\n\n## Verification\n\nRan the task-level verification command. All 36 tests in test_output.py pass (25 existing + 11 new). Also ran the full engine test suite (207 tests) — all pass.\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `cd engine && .venv/bin/python -m pytest tests/test_output.py -v -W ignore::DeprecationWarning` | 0 | ✅ pass | 0.39s |\n| 2 | `cd engine && .venv/bin/python -m pytest tests/ -v -W ignore::DeprecationWarning` | 0 | ✅ pass | 1.06s |\n\n## Diagnostics\n\nNo runtime observability surfaces added — this is a stateless function extension. Inspect DXF output by reading the generated bytes through `ezdxf.read()` and checking `doc.header[\"$INSUNITS\"]`, polyline coordinates, and layer assignments.\n\n## Deviations\n\nThe test for \"no units omits $INSUNITS header\" was adjusted: ezdxf's R2000 template sets `$INSUNITS` to 6 (meters) by default, not 0 (unitless) as the plan assumed. The test was corrected to assert the actual ezdxf default of 6.\n\n## Known Issues\n\nNone.\n\n## Files Created/Modified\n\n- `engine/output/dxf.py` — Extended `generate_dxf()` with `units`, `scale_factor`, `layer_map` keyword args; added `_INSUNITS_MAP` and `_MEASUREMENT_MAP` constants; `_add_path_to_msp()` now accepts and applies `scale_factor`\n- `engine/api/routes.py` — Added `units` and `scale_factor` Form params to `/engine/simplify`; extended `_format_response()` to forward them to `generate_dxf()`; added `VALID_UNITS` constant and validation\n- `engine/tests/test_output.py` — Added `TestDXFUnitsAndScale` class with 11 tests covering scale conversion, DXF headers, layer mapping, and combined feature usage\n","path":".gsd/milestones/M003/slices/S01/tasks/T01-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1491,"cacheRead":75464,"cacheWrite":606,"totalTokens":77562,"cost":{"input":0.000005,"output":0.037275,"cacheRead":0.037732,"cacheWrite":0.0037875,"total":0.0787995}},"stopReason":"toolUse","timestamp":1774505774186}} +{"type":"message","id":"1fdde22e","parentId":"19cb44f3","timestamp":"2026-03-26T06:16:45.289Z","message":{"role":"toolResult","toolCallId":"toolu_0133bLvywJnAzhaXc2MEGDGJ","toolName":"write","content":[{"type":"text","text":"Successfully wrote 4519 bytes to .gsd/milestones/M003/slices/S01/tasks/T01-SUMMARY.md"}],"isError":false,"timestamp":1774505805288}} +{"type":"message","id":"75268b96","parentId":"1fdde22e","timestamp":"2026-03-26T06:16:59.175Z","message":{"role":"assistant","content":[{"type":"toolCall","id":"toolu_012oe1m6nKjZmSqDmamyfGPX","name":"gsd_task_complete","arguments":{"blockerDiscovered":false,"deviations":"Adjusted test_no_units_omits_insunits_header: ezdxf R2000 defaults $INSUNITS to 6 (meters) not 0 (unitless) as plan assumed.","keyDecisions":["DXF $INSUNITS codes: inches=1, mm=4; $MEASUREMENT: inches=0, mm=1","layer_map is index-based (dict[int, str]) with island auto-layer fallback","scale_factor applied uniformly to all (x, y) coords; caller computes the value"],"keyFiles":["engine/output/dxf.py","engine/api/routes.py","engine/tests/test_output.py"],"knownIssues":"None.","milestoneId":"M003","narrative":"Extended generate_dxf() with three keyword-only args (units, scale_factor, layer_map), set $INSUNITS/$MEASUREMENT DXF headers for inches/mm, applied scale_factor to all polyline coordinates, added layer_map for custom DXF layer assignment.

Fix these issues before completing the task.\n\n## Working Directory\n\nYour working directory is `/home/aux/development/xpltdco/kerf-engine`. All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M003/slices/S01/S01-PLAN.md`\n- Task plan source: `.gsd/milestones/M003/slices/S01/tasks/T02-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M003/slices/S01/tasks/T01-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M003/slices/S01/tasks/T02-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M003/slices/S01/tasks/T02-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T02 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M003/slices/S01/S01-PLAN.md`\n**Goal:** Complete Export view (View 3) with DXF/SVG/PNG download.

Runs `validateForExport()` on mount and when objects change\n- Canvas preview: a small thumbnail of the current design (use Konva `stage.toDataURL()` from the stageRef passed through App.tsx, captured before navigating to export view)\n- Download button: disabled when blocking errors exist; triggers the appropriate export flow\n\nExport flows by format:\n- **DXF**: Call `composeCanvasSVG()` → call `exportAsDxf()` with units and scale_factor (1/96 for inches, 25.4/96 for mm) → `triggerDownload()` with the returned blob and filename `export.dxf`\n- **SVG**: Call `composeCanvasSVG()` → create blob from SVG string → `triggerDownload()` with filename `export.svg`\n- **PNG**: Use the preview data URL (captured from Konva stage before navigating) or re-render. Since stageRef may not be mounted in View 3, capture PNG data URL before transitioning to export view and pass it as a prop. Convert data URL to blob → `triggerDownload()` with filename `export.png`\n\nPNG capture strategy: When user clicks 'Export' in View 2, capture `stageRef.current.toDataURL({ pixelRatio: 2 })` and store in App.tsx state, then navigate to export view. This avoids needing the Konva stage mounted in View 3.\n\nApp.tsx updates:\n- Add `pngDataUrl` state, set it in the onExport handler before view transition\n- Pass `pngDataUrl` to ExportView\n- Wire ExportView's onBack to navigate back to canvas view\n\nCSS: New `ExportView.module.css` with the view layout.

Fix these issues before completing the task.\n\n## Working Directory\n\nYour working directory is `/home/aux/development/xpltdco/kerf-engine`. All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M003/slices/S01/S01-PLAN.md`\n- Task plan source: `.gsd/milestones/M003/slices/S01/tasks/T03-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M003/slices/S01/tasks/T01-SUMMARY.md`\n- `.gsd/milestones/M003/slices/S01/tasks/T02-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1. Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n7. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n8. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n9. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n - exercise the real flow in the browser\n - prefer `browser_batch` when the next few actions are obvious and sequential\n - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n - use `browser_diff` when an action's effect is ambiguous\n - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n - record verification in terms of explicit checks passed/failed, not only prose interpretation\n10. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n11. **If execution is running long or verification fails:**\n\n **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n11. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n12. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n13. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n14. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n15. Write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M003/slices/S01/tasks/T03-SUMMARY.md`\n16. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n17. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/development/xpltdco/kerf-engine`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/development/xpltdco/kerf-engine/.gsd/milestones/M003/slices/S01/tasks/T03-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T03 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M003/slices/S01/S01-PLAN.md`\n**Goal:** Complete Export view (View 3) with DXF/SVG/PNG download.

service with SVG composition, validation, and DXF API client\n\nThis task creates the core export logic as pure utility functions: (1) `composeCanvasSVG()` renders visible canvas objects into an SVG string with correct coordinate space and real-world unit dimensions, (2) `validateForExport()` checks for unconverted text objects (blocking error), raster-only images (warning), and missing artboard (blocking error), (3) `exportDxf()` in the API client POSTs composed SVG to `/engine/simplify?output_format=dxf` with `units` and `scale_factor` params and returns a Blob, (4) `triggerDownload()` creates a hidden anchor + blob URL to trigger browser download with proper cleanup.\n\nSVG composition details:\n- The SVG viewBox matches artboard dimensions in pixels\n- `width`/`height` attributes use real-world units (e.g., `width=\"4in\"` or `width=\"101.6mm\"`)\n- RectObject → ``, CircleObject → ``, EllipseObject → ``, LineObject → ``\n- ImageObject with SVG blob src → inline the SVG content (extract path data from blob URL)\n- ImageObject with raster src → skip (validation warns about this)\n- TextObject → error (validation blocks this — must be converted to paths first)\n- Objects with `visible: false` are skipped\n- All coordinates are in the artboard's pixel space (the engine handles conversion via scale_factor)\n\nDXF API client:\n- New function `exportAsDxf(svgContent: string, units: 'inches' | 'mm', scaleFactor: number, signal?: AbortSignal): Promise`\n- Uses FormData with file as Blob, output_format=dxf, units, scale_factor\n- Returns `response.blob()` not `response.json()`\n\nUnit tests cover: SVG composition with known objects produces correct SVG elements, validation catches text objects, validation warns on raster images, coordinate space is correct.\n\n## Inputs\n\n- ``app/src/types/canvas.ts` — CanvasObject union type (rect, circle, ellipse, line, image, text), ArtboardConfig`\n- ``app/src/utils/artboardShapes.ts` — toPx(), fromPx(), PPI constant (96)`\n- ``app/src/api/engine.ts` — existing API client with traceImage() and simplifyVector() patterns`\n- ``app/src/App.tsx` — updated in T02 with lifted canvas state (provides the

An Export button was added to DesignCanvas's toolbar area. The `handleExport` callback in App.tsx captures a 2x PNG data URL from the Konva stage before navigating to the export view, storing it in `pngDataUrl` state for later use by ExportView (T04).
