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/M014/M014-ROADMAP.md`\n\n# M014: \n\n## Vision\nRestructure technique pages to be broader (per-creator+category across videos), deeper (H2/H3 nesting with TOC), multi-source (compose new video content into existing pages), with inline citations linking prose claims to source moments, admin multi-source management, and section-level search with deep linking.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Synthesis Prompt v5 — Nested Sections + Citations | high | — | ✅ | Run test harness with new prompt → output has list-of-objects body_sections with H2/H3 nesting, citation markers on key claims, broader page scope. |\n| S02 | Composition Prompt + Test Harness Compose Mode | high | S01 | ⬜ | Run test harness --compose mode with existing page + new moments → merged output with deduplication, new sections, updated citations. |\n| S03 | Data Model + Migration | low | — | ⬜ | Alembic migration runs clean.

The prompt receives three inputs: existing page JSON, new moments list, and creator name. Must define merge semantics (preserve existing prose, integrate new material into existing sections or create new ones), deduplication rules (enrich rather than repeat), citation re-indexing scheme (existing [0]-[N-1], new [N]-[N+M-1]), and output format (same SynthesisResult/SynthesizedPage v2 schema as synthesis).\n\nSteps:\n1. Read `prompts/stage5_synthesis.txt` to understand voice/tone rules and v2 output format — the compose prompt must reference the same writing standards but NOT duplicate them (the compose prompt is self-contained).\n2. Write `prompts/stage5_compose.txt` with these sections:\n   - Role/context preamble explaining the composition task\n   - Input format: `<existing_page>`, `<existing_moments>`, `<new_moments>`, `<creator>` XML tags\n   - Merge rules: preserve existing prose verbatim where correct; add new sections for genuinely new territory; enrich existing sections with new detail where topics overlap\n   - Deduplication guidance with examples of 'enriching' vs 'duplicating'\n   - Citation re-indexing rules: existing moments keep indices [0]-[N-1], new moments get [N]-[N+M-1], composed output uses the unified index space\n   - Section ordering: maintain workflow-order rule from synthesis\n   - Output format: same SynthesisResult JSON with v2 body_sections (list[BodySection])\n   - Include a concrete JSON example showing composed output with mixed old/new citations\n3. Validate the prompt structurally: check that the JSON example parses as valid SynthesisResult, citation rules section mentions the dual-index scheme, merge rules section is present.\n  - Estimate: 45m\n  - Files: prompts/stage5_compose.txt, prompts/stage5_synthesis.txt\n  - Verify: python3 -c \"\nimport json, pathlib, re\np = pathlib.Path('prompts/stage5_compose.txt')\nassert p.exists(), 'prompt file missing'\ntxt = p.read_text()\nassert len(txt) > 2000, f'prompt too short: {len(txt)} chars'\nfor section in ['existing_page', 'new_moments', 'existing_moments', 'creator', 'Citation', 'dedup', 'Merge']:\n    assert any(s.lower() in txt.lower() for s in [section]), f'missing section: {section}'\n# Check JSON example is valid\njson_match = re.search(r'```json\\n(.*?)```', txt, re.DOTALL)\nassert json_match, 'no JSON example found'\njson.loads(json_match.group(1))\nprint('All structural checks passed')\n\"\n- [x] **T02: Added compose subcommand with build_compose_prompt(), run_compose(), and CLI wiring for offline composition testing** — Add a `compose` subcommand to `backend/pipeline/test_harness.py` that loads an existing page JSON + new moments fixture, builds a compose user prompt, calls the LLM via the compose prompt, and validates the output. Also extract the compose user-prompt builder as a testable function.\n\nSteps:\n1. Read `backend/pipeline/test_harness.py` fully to understand the existing `run` and `promote` subcommand patterns.\n2. Add a `build_compose_prompt()` function that takes:\n   - `existing_page: dict` (SynthesizedPage as dict, from prior synthesis output)\n   - `existing_moments: list[tuple[MockKeyMoment, dict]]` (the original moments the page was built from)\n   - `new_moments: list[tuple[MockKeyMoment, dict]]` (new video's moments to compose in)\n   - `creator_name: str`\n   Returns: the user prompt string with `<existing_page>`, `<existing_moments>`, `<new_moments>`, and `<creator>` XML tags. Existing moments get indices [0]-[N-1], new moments get [N]-[N+M-1]. Uses `build_moments_text()` for formatting moment lists.\n3. Add a `run_compose()` function (parallel to `run_synthesis()`) that:\n   - Loads the existing page JSON and validates as SynthesizedPage\n   - Loads the new fixture via existing `load_fixture()`\n   - Filters new moments by category to match `existing_page.topic_category`\n   - Needs the existing moments for citation context — accept them as a separate fixture or extract from the existing page's moment_indices + a moments fixture\n   - Calls `build_compose_prompt()` to build the user prompt\n   - Calls LLM with compose system prompt\n   - Parses response as SynthesisResult\n   - Runs citation validation with moment_count = len(existing_moments) + len(new_moments)\n   - Logs compose-specific metrics: word count before/after, sections before/after, new sections added\n4. Register `compose` subcommand in the `main()` argparse with args: `--existing-page` (required), `--fixture` (required), `--existing-fixture` (required, original moments fixture for citation context), `--prompt`, `--output`, `--category`, `--model`, `--modality`.\n5. Wire the subcommand handler to call `run_compose()` and write output JSON.\n6. Verify: `cd backend && python -m pipeline.test_harness compose --help` exits 0.\n  - Estimate: 1h\n  - Files: backend/pipeline/test_harness.py\n  - Verify: cd backend && python -m pipeline.test_harness compose --help\n- [x] **T03: 16 unit tests covering compose prompt XML structure, citation offset math, category filtering, and edge cases — all passing** — Write unit tests for the compose harness plumbing — no LLM calls. Tests cover prompt construction, citation re-indexing math, category filtering, word count comparison, and edge cases.\n\nSteps:\n1. Read the updated `backend/pipeline/test_harness.py` (from T02) to understand `build_compose_prompt()` signature and `run_compose()` interface.\n2. Read `backend/pipeline/test_harness_v2_format.py` for test patterns (helper functions, BodySection construction, etc.).\n3. Create `backend/pipeline/test_harness_compose.py` with these test classes:\n   - `TestBuildComposePrompt`: \n     - Existing page + 3 old moments + 2 new moments → prompt contains all XML tags, old moments indexed [0]-[2], new moments indexed [3]-[4]\n     - Creator name appears in `<creator>` tag\n     - Existing page JSON appears in `<existing_page>` tag and is valid JSON\n     - Moment text uses same format as `build_moments_text()`\n   - `TestCitationReindexing`:\n     - 5 old + 3 new moments → valid citation range is [0]-[7]\n     - validate_citations() with moment_count=8 accepts citations in [0]-[7]\n     - validate_citations() with moment_count=8 rejects citation [8]\n   - `TestCategoryFiltering`:\n     - Build fixture with moments in 2 categories → compose with existing page of category A → only category A new moments used\n   - `TestEdgeCases`:\n     - Empty new moments list → prompt still valid, just no new_moments content\n     - Single new moment → prompt has one entry at index [N]\n     - Existing page with no subsections → handled correctly\n4. Run tests: `cd backend && python -m pytest pipeline/test_harness_compose.py -v`\n  - Estimate: 45m\n  - Files: backend/pipeline/test_harness_compose.py\n  - Verify: cd backend && python -m pytest pipeline/test_harness_compose.py -v\n\n---\n\n### Requirements\nSource: `.gsd/REQUIREMENTS.md`\n\n# Requirements\n\n## R001 — Whisper Transcription Pipeline\n**Status:** validated\n**Description:** Desktop Python script that accepts video files (MP4/MKV), extracts audio via ffmpeg, runs Whisper large-v3 on RTX 4090, and outputs timestamped transcript JSON with segment-level timestamps and word-level timing.

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 `<available_skills>` 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 the slice involved runtime behavior, fill the **Operational Readiness** section (Q8) in the slice summary: health signal, failure signal, recovery procedure, and monitoring gaps. Omit entirely for simple slices with no runtime concerns.\n6. 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.\n7. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M014/slices/S02/S02-SUMMARY.md` (compress all task summaries).\n8. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M014/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.\n9. Review task summaries for `key_decisions`. Append any significant decisions to `.gsd/DECISIONS.md` if missing.\n10. 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.\n11. 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.\n12. Do not run git commands — the system commits your changes and handles any merge after this unit succeeds.\n13. 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/projects/content-to-kb-automator/.gsd/milestones/M014/slices/S02/S02-SUMMARY.md` and `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M014/slices/S02/S02-UAT.md` automatically.**\n\nWhen done, say: \"Slice S02 complete.\"","display":false,"id":"1a14060b","parentId":"e429842f","timestamp":"2026-04-03T01:08:42.489Z"}

It defines four XML input tags (`<existing_page>`, `<existing_moments>`, `<new_moments>`, `<creator>`), offset-based citation re-indexing (existing moments keep [0]-[N-1], new moments get [N]-[N+M-1]), merge/enrich/dedup rules with concrete examples, workflow-ordered section placement, and v2 SynthesisResult output format with two validated JSON examples.\n\nT02 added `build_compose_prompt()` and `run_compose()` to the test harness, plus a `compose` CLI subcommand. The prompt builder constructs the XML-tagged user prompt with correct citation index offsets. `run_compose()` loads an existing page JSON + two fixture files (original moments and new moments), filters new moments by category, calls the LLM with the compose system prompt, validates the output as SynthesisResult, and logs compose-specific metrics (word count before/after, sections before/after).\n\nT03 created 16 unit tests in `test_harness_compose.py` covering prompt XML structure (6 tests), citation offset arithmetic (4 tests), category filtering (2 tests), and edge cases (4 tests including empty moments, single moment, no subsections, large offsets).

Open `prompts/stage5_compose.txt`\n2. Verify it contains XML tag references: `<existing_page>`, `<existing_moments>`, `<new_moments>`, `<creator>`\n3. Verify citation re-indexing section explains offset scheme: existing [0]-[N-1], new [N]-[N+M-1]\n4. Verify merge rules section covers: preserve existing prose, enrich vs duplicate, new section creation\n5. Verify at least one JSON example block parses as valid JSON with `pages` key and `body_sections_format: \"v2\"`\n- **Expected:** All checks pass. Prompt is >2000 chars.\n\n### Test 2: Compose CLI subcommand help\n1. Run: `cd backend && python -m pipeline.test_harness compose --help`\n- **Expected:** Exit code 0. Output shows `--existing-page`, `--fixture`, `--existing-fixture` as required args; `--prompt`, `--output`, `--category`, `--model`, `--modality` as optional.\n\n### Test 3: Unit test suite — full run from project root\n1. Run: `python -m pytest pipeline/test_harness_compose.py -v`\n- **Expected:** 16 tests pass. No errors or warnings. Runs in <2s.\n\n### Test 4: Unit test suite — full run from backend directory\n1. Run: `cd backend && python -m pytest pipeline/test_harness_compose.py -v`\n- **Expected:** 16 tests pass. Same results as Test 3.\n\n### Test 5: Prompt XML tag population\n1. In a Python shell, import `build_compose_prompt` from `pipeline.test_harness`\n2. Call with a mock existing page dict, 3 existing moments, 2 new moments, and a creator name\n3. Verify the returned string contains `<existing_page>` with valid JSON inside\n4. Verify `<existing_moments>` section has indices [0], [1], [2]\n5. Verify `<new_moments>` section has indices [3], [4] (offset by 3)\n6. Verify `<creator>` tag contains the creator name\n- **Expected:** All XML tags present with correct content and citation indices.\n\n### Test 6: Category filtering behavior\n1. Create two MockKeyMoment objects with different `topic_category` values (e.g., \"Sound Design\" and \"Mixing\")\n2. Create an existing page dict with `topic_category: \"Sound Design\"`\n3. Call `build_compose_prompt` with both moments as new_moments\n4. Verify only the \"Sound Design\" moment appears in the prompt (filtering happens in run_compose, not build_compose_prompt — verify at run_compose level or in test suite)\n- **Expected:** TestCategoryFiltering tests confirm only matching-category moments are used.\n\n### Edge Cases\n- **Empty new moments:** `build_compose_prompt` with empty new_moments list produces valid prompt with empty `<new_moments>` section\n- **Single new moment:** Index starts at N (offset from existing count)\n- **Large offset:** 50 existing + 10 new moments produces indices [50]-[59] for new moments","verification":"All three verification gates pass:\n1. `python -m pytest pipeline/test_harness_compose.py -v` — 16/16 passed (0.40s) from project root\n2. `cd backend && python -m pipeline.test_harness compose --help` — exits 0, correct arg listing\n3.
