{"type":"custom_message","customType":"gsd-auto","content":"You are executing GSD auto-mode.\n\n## Working Directory\n\nYour working directory is `/home/aux/projects/content-to-kb-automator`. All file reads, writes, and shell commands MUST operate relative to this directory. 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. **Quality gates** — for non-trivial slices, fill the Threat Surface (Q3) and Requirement Impact (Q4) sections in the slice plan:\n   - **Threat Surface:** Identify abuse scenarios, data exposure risks, and input trust boundaries. Required when the slice handles user input, authentication, authorization, or sensitive data. Omit entirely for internal refactoring or simple changes.\n   - **Requirement Impact:** List which existing requirements this slice touches, what must be re-verified after shipping, and which prior decisions should be reconsidered. Omit entirely if no existing requirements are affected.\n   - For each task in a non-trivial slice, fill Failure Modes (Q5), Load Profile (Q6), and Negative Tests (Q7) in the task plan when the task has external dependencies, shared resources, or non-trivial input handling. Omit for simple tasks.\n6. 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\n7. **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/projects/content-to-kb-automator/.gsd/milestones/M005/slices/S03/S03-PLAN.md` and `.gsd/milestones/M005/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.\n8. **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.\n    - **Quality gate coverage:** For non-trivial slices, Threat Surface and Requirement Impact sections are present and specific (not placeholder text). For non-trivial tasks, Failure Modes, Load Profile, and Negative Tests are addressed in the task plan.\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/projects/content-to-kb-automator`.\n\n**You MUST call `gsd_plan_slice` to persist the planning state before finishing.**\n\nWhen done, say: \"Slice S03 planned.\"\n## Requirements Advanced\n\n- R006 — Technique page now has structured 2-column layout separating prose from reference material, improving readability and navigation\n\n## Requirements Validated\n\nNone.\n\n## Requirements Invalidated or Re-scoped\n\nNone.\n\n## UNIT: Plan Slice S03 (\"Key Moment Card Redesign\") — Milestone M005\n\n## Inlined Context (preloaded — do not re-read these files)\n\n### Milestone Roadmap\nSource: `.gsd/milestones/M005/M005-ROADMAP.md`\n\n# M005: \n\n## Vision\nAdd a pipeline management dashboard under admin (trigger, pause, monitor, view logs/token usage/JSON responses), redesign technique pages with a 2-column layout (prose left, moments/chains/plugins right), and clean up key moment card presentation for consistent readability.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Pipeline Admin Dashboard | high | — | ✅ | Admin page at /admin/pipeline shows video list with status, retrigger button, and log viewer with token counts and expandable JSON responses |\n| S02 | Technique Page 2-Column Layout | medium | — | ✅ | Technique page shows prose content on left, plugins/moments/chains on right at desktop widths. Single column on mobile. |\n| S03 | Key Moment Card Redesign | low | S02 | ⬜ | Key moment cards show title prominently on its own line, with source file, timestamp, and type badge on a clean secondary row |\n\n---\n\n### Slice Research\nSource: `.gsd/milestones/M005/slices/S03/S03-RESEARCH.md`\n\n# S03: Key Moment Card Redesign — Research\n\n**Date:** 2026-03-30\n\n## Summary\n\nThe key moment cards in the technique page sidebar need a layout adjustment: move the title to its own prominent line, then show source filename, timestamp, and content type badge on a clean secondary metadata row. This is a straightforward CSS + minor JSX restructure within a single component file and one CSS file. No API changes, no new data fields, no new dependencies.\n\nThe cards currently render inside a 22rem sidebar (established by S02). The `.technique-moment__header` is a flex row with `flex-wrap: wrap` containing title, source, timestamp, and badge all inline. At 22rem width this wraps unpredictably. The fix is to split the header into two explicit rows: a title row and a metadata row.\n\n## Recommendation\n\nRestructure the card JSX to separate the title from the metadata. The title becomes a standalone element outside the metadata row. The metadata row (source filename, timestamp, content type badge) becomes its own flex container. This gives the title full width and visual prominence, while metadata items stay compact on a single secondary line.\n\nNo need for new CSS custom properties — the existing `--color-text-secondary`, `--color-text-muted`, and badge variables cover everything. The summary paragraph below the header remains unchanged.\n\n## Implementation Landscape\n\n### Key Files\n\n- `frontend/src/pages/TechniquePage.tsx` (lines 413–430) — Key moment card JSX. Currently renders a single `.technique-moment__header` div with title, source, timestamp, and badge as siblings. Needs restructuring: title pulled out of header, header renamed/repurposed to metadata row.\n- `frontend/src/App.css` (lines 1337–1380) — Key moment card styles. `.technique-moment__header` is `display: flex; align-items: center; gap: 0.5rem; flex-wrap: wrap`. Needs: title gets its own block-level style, header becomes a metadata-only flex row with smaller gap.\n- `frontend/src/api/public-client.ts` (line 29) — `KeyMomentSummary` interface. No changes needed — all required fields (`title`, `video_filename`, `start_time`, `end_time`, `content_type`) already exist.\n\n### Current Card Structure (JSX)\n```\n<li className=\"technique-moment\">\n  <div className=\"technique-moment__header\">     ← single flex row\n    <span className=\"technique-moment__title\">   ← title inline with metadata\n    <span className=\"technique-moment__source\">  ← source filename\n    <span className=\"technique-moment__time\">    ← timestamp range\n    <span className=\"badge badge--content-type\"> ← type badge\n  </div>\n  <p className=\"technique-moment__summary\">      ← summary text\n</li>\n```\n\n### Target Card Structure (JSX)\n```\n<li className=\"technique-moment\">\n  <h3 className=\"technique-moment__title\">       ← title on its own line, prominent\n  <div className=\"technique-moment__meta\">        ← metadata row\n    <span className=\"technique-moment__source\">   ← source filename\n    <span className=\"technique-moment__time\">     ← timestamp range\n    <span className=\"badge badge--content-type\">  ← type badge\n  </div>\n  <p className=\"technique-moment__summary\">       ← summary text (unchanged)\n</li>\n```\n\n### Build Order\n\n1. Restructure JSX in TechniquePage.tsx — pull title out of header div, rename header to `__meta`, change title from `<span>` to block-level element\n2. Update CSS in App.css — adjust `.technique-moment__title` to block display with bottom margin, add `.technique-moment__meta` as the flex row (inheriting current `__header` styles with adjustments), remove or redirect `__header` styles\n3. Verify at desktop (22rem sidebar) and mobile (single column) widths\n\nSingle task — the JSX and CSS changes are tightly coupled and should be done together.\n\n### Verification Approach\n\n- `npx tsc --noEmit` — TypeScript compiles cleanly\n- `npm run build` — production build succeeds\n- Visual check at desktop width: title is on its own line, metadata items (source, timestamp, badge) are on a secondary row\n- Visual check at mobile width (≤768px): card still renders cleanly in single-column layout\n- No hardcoded colors in new/modified CSS rules (all use existing custom properties)\n\n## Constraints\n\n- Sidebar width is fixed at 22rem (D019). Card must look good within this constraint.\n- Existing badge classes (`.badge`, `.badge--content-type`) must not be modified — they're shared across the app.\n- No new CSS custom properties needed — existing color tokens cover the design.\n- The `<ol>` list wrapper and `<li>` card container structure should be preserved for semantic correctness.\n\n---\n\n### Decisions\nSource: `.gsd/DECISIONS.md`\n\n# Decisions (compact)\nFields: id | when | scope | decision | choice | rationale | revisable | made_by\n\nD019 | M005/S02 | frontend-layout | Technique page layout structure | CSS grid 2-column layout: 1fr main + 22rem sticky sidebar, collapsing to single column at 768px. Page max-width widened from 48rem to 64rem. | 22rem sidebar provides enough room for moment cards and plugin lists without cramming. 64rem total width accommodates both columns comfortably on standard desktop displays.

This causes `relationship(...)` calls below it to fail with \"MappedColumn object is not callable\".\n\n**Fix:** Import with an alias: `from sqlalchemy.orm import relationship as sa_relationship` and use `sa_relationship(...)` throughout. Alternatively, rename the database column, but the spec defines `relationship` as the column name so we preserved it.\n\n## Docker Compose variable interpolation and `:?` syntax\n\n**Context:** `${VAR:?error message}` in docker-compose.yml makes `docker compose config` fail when the variable is unset, even if `env_file: required: false` is used. The `required: false` only controls whether the `.env` file must exist — it does NOT provide defaults for variables referenced with `:?`.\n\n**Fix:** Use `${VAR:-default}` for variables that need a fallback, or ensure the variable is always set in the environment.\n\n## Host port 8000 conflict with kerf-engine\n\n**Context:** The kerf-engine Docker container (`kerf-engine-kerf-engine-1`) binds to `0.0.0.0:8000`. When testing the Chrysopedia API locally (outside Docker), curl requests to `localhost:8000` hit the kerf-engine container instead of the local uvicorn process, even when uvicorn binds to `127.0.0.1:8000`.\n\n**Fix:** Use an alternate port (e.g., 8001) for local testing. In Docker Compose, chrysopedia-api maps `127.0.0.1:8000:8000` which is fine because it goes through Docker's port forwarding, but will conflict with kerf-engine if both stacks run simultaneously. Consider changing one project's external port mapping.\n\n## asyncpg rejects timezone-aware datetimes for TIMESTAMP WITHOUT TIME ZONE columns\n\n**Context:** SQLAlchemy models using `default=datetime.now(timezone.utc)` produce timezone-aware Python datetimes. When the PostgreSQL column type is `TIMESTAMP WITHOUT TIME ZONE` (the default), asyncpg raises `DataError: can't subtract offset-naive and offset-aware datetimes`. This only surfaces when running against a real PostgreSQL database — SQLite-based tests won't catch it.\n\n**Fix:** Use `datetime.now(timezone.utc).replace(tzinfo=None)` in the `_now()` helper, or change the column type to `TIMESTAMP WITH TIME ZONE`. We chose the former since the existing schema uses naive timestamps.\n\n## asyncpg NullPool required for pytest-asyncio integration tests\n\n**Context:** When using a session-scoped SQLAlchemy async engine with asyncpg in pytest-asyncio tests, the connection pool reuses connections across fixtures and test functions. This causes `InterfaceError: cannot perform operation: another operation is in progress` because the ASGI test client's session holds a connection while cleanup/verification fixtures try to use the same pool.\n\n**Fix:** Use `poolclass=NullPool` when creating the test engine. Each connection is created fresh and immediately closed, eliminating contention. Performance cost is negligible for test suites.\n\n## Testing Celery tasks that use sync SQLAlchemy: patch module-level globals\n\n**Context:** Pipeline stages in `pipeline/stages.py` create their own sync SQLAlchemy engine/session via module-level `_engine` and `_SessionLocal` globals (because Celery is sync, not async). Tests need to redirect these to the test database, but the engine is created lazily at module scope.\n\n**Fix:** Patch the module globals directly: `unittest.mock.patch.object(stages, '_engine', test_engine)` and `unittest.mock.patch.object(stages, '_SessionLocal', test_session_factory)`. This redirects all DB access in stage functions to the test database without modifying production code.\n\n## Lazy imports in FastAPI handlers defeat simple mock patching\n\n**Context:** When a FastAPI handler imports a function lazily (inside the function body) like `from pipeline.stages import run_pipeline`, patching `routers.ingest.run_pipeline` has no effect because the name is re-bound on every call from the source module.\n\n**Fix:** Patch at the source module: `unittest.mock.patch('pipeline.stages.run_pipeline')`. The lazy import will pick up the mock from the source module. This applies to any handler that uses lazy imports to avoid circular dependencies at module load time.\n\n## Separate async/sync clients for FastAPI vs Celery\n\n**Context:** The Chrysopedia backend has both sync Celery tasks (pipeline stages using `openai.OpenAI`, `QdrantClient`, sync SQLAlchemy) and async FastAPI handlers. Reusing sync clients in async handlers blocks the event loop; reusing async clients in Celery risks nested event loop errors.\n\n**Fix:** Create separate client classes: `SearchService` (async, for FastAPI request path) wraps `openai.AsyncOpenAI` and `AsyncQdrantClient`. The pipeline's `EmbeddingClient` and `QdrantManager` (sync, for Celery) remain untouched. This doubles the client code surface but eliminates the async/sync mismatch class of bugs entirely.\n\n## Mocking SearchService at the router dependency level for tests\n\n**Context:** The search endpoint creates a `SearchService` instance internally. Testing search results with real embedding API and Qdrant is fragile (external dependencies). Mocking individual `openai.AsyncOpenAI` or `AsyncQdrantClient` is complex.\n\n**Fix:** Mock `SearchService` at the router level by patching the service instance in the endpoint function. This gives full control over search results in tests without complex async mock setup. Used in `test_search.py` — mock returns canned `SearchResponse` dicts.\n\n## Frontend detail page without a single-resource GET endpoint\n\n**Context:** The review queue backend has `GET /review/queue` (list, paginated) but no `GET /review/moments/{id}` for fetching a single moment. The MomentDetail page needs to display one specific moment by ID from the URL params.\n\n**Fix:** MomentDetail fetches the full queue with `limit=500` and filters client-side by ID. This works for a single-admin tool with small datasets but would not scale. If the moment count grows significantly, add a dedicated `GET /review/moments/{id}` endpoint to the review router.\n\n**Update (M004/S01):** Fixed properly — added `GET /review/moments/{id}` endpoint. Always add single-resource GET endpoints alongside list endpoints.\n\n## CSS custom property count estimation\n\n**Context:** When planning a full color abstraction pass (replacing all hardcoded hex/rgba with CSS custom properties), initial estimates based on counting unique colors will significantly undercount the required tokens.\n\n**Rule:** Plan for 2-3x the obvious color count. Reasons: hover/focus/active state variants, badge/status color pairs (background + text), subtle vs strong accent variants, shadow colors, overlay backgrounds, and distinct semantic contexts (surface vs input vs card). M004/S02 planned ~30, needed 77.\n\n## Chained selectinload for cross-relation field population\n\n**Context:** When an API response needs a field from a joined relation (e.g., `key_moment.source_video.filename`), Pydantic's `from_attributes` auto-mapping can't traverse the join. The field appears as a flat attribute on the response schema but comes from a different table.\n\n**Fix:** Chain `.selectinload()` in the query (e.g., `.selectinload(TechniquePage.key_moments).selectinload(KeyMoment.source_video)`), then post-process in a loop to copy the joined value into the schema field. This keeps the query efficient (two SELECTs) and the response schema flat.\n\n## Pre-overwrite snapshot pattern for article versioning\n\n**Context:** Need to track content versions without complex CDC (change data capture) infrastructure. The content lives in a single mutable row that gets overwritten on each pipeline run.\n\n**Pattern:** Before mutating the row, SELECT its current state, serialize relevant fields to JSONB (`content_snapshot`), attach pipeline metadata (prompt file hashes, model config) as a second JSONB column, and INSERT into a versions table. Use best-effort error handling — snapshot failure logs ERROR but doesn't block the primary write. Composite unique index on (entity_id, version_number) enforces ordering at DB level.\n\n## Stage 4 classification data stored in Redis (not DB columns)\n\n**Context:** The KeyMoment SQLAlchemy model doesn't have `topic_tags` or `topic_category` columns. Stage 4 classification needs somewhere to store per-moment tag assignments that stage 5 can read.\n\n**Fix:** Store classification results in Redis under key `chrysopedia:classification:{video_id}` with a 24-hour TTL. Stage 5 reads from Redis. This avoids schema migrations during initial pipeline development. The data is ephemeral — if Redis loses it, re-running stage 4 regenerates it.\n\n## QdrantManager uses random UUIDs for point IDs\n\n**Context:** `QdrantManager.upsert_technique_pages()` and `upsert_key_moments()` generate `uuid4()` for each Qdrant point. Re-indexing the same content creates duplicate points rather than updating existing ones.\n\n**Fix (deferred):** Use deterministic UUIDs based on content hash (e.g., `uuid5(NAMESPACE, f\"{technique_slug}:{section}\")`) so re-indexing overwrites the same points. This should be addressed before running the pipeline on production data to avoid index bloat.\n\n## Non-blocking side-effect pattern for external service calls in pipelines\n\n**Context:** Celery pipeline stages that call external services (embedding API, Qdrant) should not fail the entire pipeline if those services are down. Stage 6 (embed_and_index) is valuable but not critical — the pipeline's primary output (technique pages in PostgreSQL) doesn't depend on it.\n\n**Fix:** Use `max_retries=0` and a catch-all exception handler that logs WARNING and returns without raising. The pipeline orchestrator chains stage 6 after stage 5 but a failure there doesn't prevent `processing_status` from reaching its final state. This pattern applies to any \"best-effort enrichment\" stage in a pipeline.\n\n## Container healthcheck tool availability varies by base image\n\n**Context:** Qdrant (distroless-ish), Ollama, and nginx-alpine images don't have curl or wget. Standard healthcheck patterns like `curl -f http://localhost:PORT/health` fail silently inside these containers.\n\n**Fix by image:**\n- **Ollama:** Use `ollama list` (built-in CLI)\n- **Qdrant:** Use `bash -c 'echo > /dev/tcp/localhost/6333'` (bash is available)\n- **nginx-alpine:** Use `curl` (available) but NOT busybox `wget` (fails on localhost)\n- **Celery worker (same image as API):** Use `celery -A worker inspect ping` instead of HTTP healthcheck\n\n**Rule:** Always `docker exec <container> <healthcheck-cmd>` to verify the command works before deploying.\n\n## XPLTD domain setup flow\n\n**Context:** Adding a new external domain (like chrysopedia.com) to the XPLTD infrastructure requires three steps across two machines.\n\n**Flow:**\n1. **AdGuard on ub01 (10.0.0.10):** Add DNS rewrite via API: `POST /control/rewrite/add` with `{domain, answer: \"10.0.0.9\"}`\n2. **nginx on nuc01 (10.0.0.9):** Create server block in `/etc/nginx/sites-enabled/{domain}.conf` with `proxy_pass http://10.0.0.10:{port}`\n3. **Certbot on nuc01:** `sudo certbot --nginx -d {domain}` (requires external DNS A record or CNAME pointing to public IP first)\n\n**Note:** The AD DNS servers (10.0.0.15/.16) may already have CNAME entries for domains. Check `nslookup {domain} 10.0.0.15` before assuming setup is needed. ub01's resolv.conf uses AD DNS, not AdGuard, so `curl {domain}` from ub01 requires the AD DNS chain to resolve.\n\n## Alembic env.py sys.path needs both local and Docker paths\n\n**Context:** Alembic's env.py imports from `database` and `models`, which live in `backend/` locally but at `/app/` (the WORKDIR) inside Docker. The original `sys.path.insert(0, \"../backend\")` works locally but fails in Docker.\n\n**Fix:** Add both paths: `sys.path.insert(0, os.path.join(os.path.dirname(__file__), \"..\", \"backend\"))` AND `sys.path.insert(0, os.path.join(os.path.dirname(__file__), \"..\"))`. The second resolves to `/app/` inside Docker.\n\n## Nginx stale DNS after Docker container rebuild\n\n**Context:** When an API container behind an nginx reverse proxy in Docker Compose is rebuilt (new container ID, new internal IP), the nginx container's DNS resolver cache still points to the old IP. Requests through nginx return 502 Bad Gateway even though the API is healthy on its new IP.\n\n**Fix:** Restart the nginx/web container after rebuilding upstream containers: `docker compose restart chrysopedia-web-8096`. Alternatively, configure nginx with `resolver 127.0.0.11 valid=10s;` in the upstream block to use Docker's embedded DNS with a short TTL, but the restart is simpler for a single-admin deployment.\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#### S02 Summary\nSource: `.gsd/milestones/M005/slices/S02/S02-SUMMARY.md`\n\n---\nid: S02\nparent: M005\nmilestone: M005\nprovides:\n  - 2-column technique page layout with 22rem sidebar containing key moments, signal chains, plugins, and related techniques\nrequires:\n  []\naffects:\n  - S03\nkey_files:\n  - frontend/src/App.css\n  - frontend/src/pages/TechniquePage.tsx\nkey_decisions:\n  - Sidebar fixed at 22rem width with sticky positioning at 1.5rem from top\n  - Page max-width widened from 48rem to 64rem to accommodate sidebar\n  - 768px breakpoint for responsive collapse aligns with existing mobile styles\npatterns_established:\n  - CSS grid 2-column layout pattern: 1fr + fixed sidebar with sticky positioning and responsive collapse\nobservability_surfaces:\n  - none\ndrill_down_paths:\n  - .gsd/milestones/M005/slices/S02/tasks/T01-SUMMARY.md\nduration: \"\"\nverification_result: passed\ncompleted_at: 2026-03-30T08:49:31.884Z\nblocker_discovered: false\n---\n\n# S02: Technique Page 2-Column Layout\n\n**Technique pages now display prose content (summary + study guide) in a left column and sidebar content (key moments, signal chains, plugins, related techniques) in a right column at desktop widths, collapsing to single column on mobile.**\n\n## What Happened\n\nThis slice restructured the technique page from a single-column flow to a 2-column CSS grid layout. The .technique-page max-width was widened from 48rem to 64rem to accommodate the sidebar. A new .technique-columns grid wrapper splits content into a 1fr main column and 22rem sidebar column with 2rem gap. The sidebar uses sticky positioning (top: 1.5rem) so navigation aids remain visible while scrolling long prose. At ≤768px the grid collapses to a single column with static positioning, preserving the existing mobile experience.\n\nIn TechniquePage.tsx, the content below the header/report-modal was wrapped in the grid container. The main column contains the Summary section and Body Sections (study guide prose). The sidebar column contains Key Moments, Signal Chains, Plugins, and Related Techniques. The header and report modal remain above the grid at full width.\n\nAll new CSS uses only structural properties (grid, gap, positioning) with no hardcoded colors, staying consistent with the existing custom property system. TypeScript compilation and production build both pass cleanly. The Docker web container was rebuilt and restarted on ub01.\n\n## Verification\n\nTypeScript compilation (tsc --noEmit) passed with zero errors. Production build (npm run build) succeeded — 46 modules, 658ms. Docker web container (chrysopedia-web-8096) rebuilt, restarted, and healthy. Browser verification confirmed 2-column layout at desktop width and single-column collapse at 375px mobile width. No hardcoded colors in new CSS rules. All plan must-haves satisfied.\n\n## New Requirements Surfaced\n\nNone.\n\n## Deviations\n\nDocker service name is chrysopedia-web not chrysopedia-web-8096 as plan stated (compose service vs container name). Had to run npm install on ub01 before type checking. TechniquePage.tsx was 505 lines not ~310 as estimated — component is larger than plan assumed.\n\n## Known Limitations\n\nNone.\n\n## Follow-ups\n\nS03 (Key Moment Card Redesign) depends on this slice — the sidebar column constrains card width to 22rem which may affect card layout decisions.\n\n## Files Created/Modified\n\n- `frontend/src/App.css` — Widened .technique-page max-width from 48rem to 64rem. Added .technique-columns CSS grid (1fr 22rem), .technique-columns__main, .technique-columns__sidebar with sticky positioning, and @media 768px breakpoint for single-column collapse.\n- `frontend/src/pages/TechniquePage.tsx` — Wrapped content sections in .technique-columns grid. Summary + body sections in __main div. Key moments + signal chains + plugins + related techniques in __sidebar div.\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- **Requirements**: `.gsd/REQUIREMENTS.md`\n- **Decisions**: `.gsd/DECISIONS.md`\n- **Roadmap**: `.gsd/milestones/M005/M005-ROADMAP.md`\n- **Slice Research**: `.gsd/milestones/M005/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. 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":"a788840e","parentId":"5ee29dd2","timestamp":"2026-03-30T08:50:57.955Z"}

Currently the card header is a single flex row with `flex-wrap: wrap` containing title, source, timestamp, and badge as siblings. At 22rem width this wraps unpredictably. The fix splits the header into two explicit rows.\n\n## Steps\n\n1. Read `frontend/src/pages/TechniquePage.tsx` around lines 413–430 to locate the key moment card JSX (the `.technique-moment` list items inside the Key Moments section within `.technique-columns__sidebar`).\n\n2. Restructure the card JSX:\n   - Pull the title `<span className=\"technique-moment__title\">` out of the `__header` div and place it before it as a standalone element. Change from `<span>` to `<h3>` for semantic correctness (it's a sub-heading within the Key Moments `<h2>` section).\n   - Rename the remaining `<div className=\"technique-moment__header\">` to `<div className=\"technique-moment__meta\">` — it now contains only source, timestamp, and badge.\n   - The `<p className=\"technique-moment__summary\">` stays unchanged after the meta div.\n   - Target structure per card:\n     ```\n     <li className=\"technique-moment\">\n       <h3 className=\"technique-moment__title\">{km.title}</h3>\n       <div className=\"technique-moment__meta\">\n         {km.video_filename && <span className=\"technique-moment__source\">...}  \n         <span className=\"technique-moment__time\">...</span>\n         <span className=\"badge badge--content-type\">...</span>\n       </div>\n       <p className=\"technique-moment__summary\">{km.summary}</p>\n     </li>\n     ```\n\n3. Read `frontend/src/App.css` around lines 1337–1380 to locate the key moment card styles.\n\n4. Update CSS:\n   - `.technique-moment__title`: Change to `display: block; margin: 0 0 0.25rem 0; font-size: 0.9375rem; font-weight: 600; line-height: 1.3;` — block display gives it its own line, bottom margin separates from meta row. Reset h3 default margins.\n   - Add `.technique-moment__meta` with the same styles as the current `__header`: `display: flex; align-items: center; gap: 0.5rem; margin-bottom: 0.25rem; flex-wrap: wrap;`\n   - Remove or comment out `.technique-moment__header` (no longer used in JSX). If other code references it, keep it but it should be dead CSS after the JSX change.\n   - All other moment card styles (`.technique-moment__time`, `.technique-moment__source`, `.technique-moment__summary`, `.badge--content-type`) remain unchanged.\n\n5. Verify:\n   - Run `cd frontend && npx tsc --noEmit` — zero errors\n   - Run `cd frontend && npm run build` — succeeds\n   - Grep for any remaining references to `technique-moment__header` in .tsx files to confirm it's fully replaced\n   - Confirm no hardcoded hex/rgba values in new or modified CSS rules\n\n## Constraints\n\n- Sidebar width is fixed at 22rem (D019). Card must look good within this constraint.\n- Do NOT modify `.badge` or `.badge--content-type` classes — they're shared across the app.\n- Preserve the `<ol>` list wrapper and `<li>` card container structure.\n- Use only existing CSS custom properties for any color values.\n- The `<h3>` for the title should not introduce unwanted default browser margins — reset with explicit margin in CSS.","estimate":"20m","expectedOutput":["`frontend/src/pages/TechniquePage.tsx` — restructured card JSX with title as standalone h3, metadata in __meta div","`frontend/src/App.css` — updated styles: __title as block element, new __meta flex row, __header removed or dead"],"files":["frontend/src/pages/TechniquePage.tsx","frontend/src/App.css"],"inputs":["`frontend/src/pages/TechniquePage.tsx` — current key moment card JSX with single-row __header layout","`frontend/src/App.css` — current key moment card styles including __header flex row"],"taskId":"T01","title":"Restructure key moment card layout: title on own line, metadata on secondary row","verify":"cd frontend && npx tsc --noEmit && npm run build && ! grep -q 'technique-moment__header' src/pages/TechniquePage.tsx && echo 'PASS'"}]}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1842,"cacheRead":70829,"cacheWrite":595,"totalTokens":73267,"cost":{"input":0.000005,"output":0.04605,"cacheRead":0.0354145,"cacheWrite":0.0037187500000000003,"total":0.08518825000000001}},"stopReason":"toolUse","timestamp":1774860669518}}
