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.

All pages get body_sections_format='v2' and technique_page_videos rows tracking contributing videos.\n**Demo:** After this: Process two COPYCATT videos. Second video's moments composed into existing page. technique_page_videos has both video IDs.\n\n## Tasks\n- [x] **T01: Added _build_compose_user_prompt(), _compose_into_existing(), and compose-or-create branching to stage5_synthesis with body_sections_format='v2' and TechniquePageVideo tracking** — Add two helper functions to stages.py and modify the stage5_synthesis per-category loop to detect existing pages and branch to the compose path.\n\n## Steps\n\n1. Add `TechniquePageVideo` to the imports from `models` at line ~27.\n\n2. Add `_build_compose_user_prompt(existing_page, existing_moments, new_moments, creator_name)` helper function:\n   - Takes an existing `TechniquePage` ORM object, a list of `KeyMoment` ORM objects (existing), a list of `(KeyMoment, dict)` tuples (new moments with classification), and creator name string\n   - Serialize existing page to dict matching SynthesizedPage shape: title, slug, topic_category, summary, body_sections, signal_chains, plugins, source_quality\n   - Format existing moments as `[0]-[N-1]` using `_build_moments_text()` pattern but from plain KeyMoment objects (not tuples with cls_info — existing moments don't have classification data, use empty dict)\n   - Format new moments as `[N]-[N+M-1]` using `_build_moments_text()` with offset indices applied\n   - Build XML-tagged user prompt: `<existing_page>`, `<existing_moments>`, `<new_moments>`, `<creator>` tags (same structure as test_harness.py's `build_compose_prompt()`)\n   - Return the user prompt string\n\n3. Add `_compose_into_existing(existing_page, existing_moments, new_moment_group, category, creator_name, system_prompt, llm, model_override, modality, hard_limit, video_id, run_id)` helper function:\n   - Load compose system prompt via `_load_prompt('stage5_compose.txt', video_id=video_id)`\n   - Call `_build_compose_user_prompt()` to build user prompt\n   - Estimate tokens via `estimate_max_tokens()`\n   - Call `llm.complete()` with compose system prompt, response_model=SynthesisResult, same callback/param pattern as `_synthesize_chunk()`\n   - Parse via `_safe_parse_llm_response()` and return SynthesisResult\n\n4. Modify the per-category loop in `stage5_synthesis()` (around line 1200):\n   - **Before** the existing chunked synthesis block, add compose detection:\n     ```\n     existing_page = session.execute(\n         select(TechniquePage).where(\n             TechniquePage.creator_id == video.creator_id,\n             func.lower(TechniquePage.topic_category) == func.lower(category),\n         )\n     ).scalars().first()\n     ```\n   - If `existing_page` is found, load its linked moments:\n     ```\n     existing_moments = session.execute(\n         select(KeyMoment)\n         .where(KeyMoment.technique_page_id == existing_page.id)\n         .order_by(KeyMoment.start_time)\n     ).scalars().all()\n     ```\n   - If existing_page AND existing_moments → compose path: call `_compose_into_existing()`, use result.pages as synthesized_pages\n   - Log INFO: 'Stage 5: Composing into existing page \\'%s\\' (%d existing moments + %d new moments)'\n   - If >1 page matches, log WARNING about multiple matches and proceed with first\n   - If no existing_page → fall through to existing synthesis block (unchanged)\n   - Wrap in `else` so existing chunked synthesis only runs when not composing\n\n5. In the persist block (around line 1380), after the `if existing:` / `else:` branch that creates/updates the page:\n   - Set `page.body_sections_format = 'v2'` on every page (both new and updated)\n   - Add TechniquePageVideo INSERT:\n     ```python\n     from sqlalchemy.dialects.postgresql import insert as pg_insert\n     stmt = pg_insert(TechniquePageVideo.__table__).values(\n         technique_page_id=page.id,\n         source_video_id=video.id,\n     ).on_conflict_do_nothing()\n     session.execute(stmt)\n     ```\n\n## Must-Haves\n\n- [ ] `_build_compose_user_prompt()` produces XML-tagged prompt with correct offset indices\n- [ ] `_compose_into_existing()` calls LLM with compose system prompt and returns SynthesisResult\n- [ ] Compose-or-create decision queries DB by creator_id + LOWER(topic_category)\n- [ ] Existing synthesis path unchanged when no existing page found\n- [ ] body_sections_format = 'v2' set on all pages\n- [ ] TechniquePageVideo row inserted for every page+video combination\n- [ ] Case-insensitive category matching (func.lower)\n\n## Failure Modes\n\n| Dependency | On error | On timeout | On malformed response |\n|------------|----------|-----------|----------------------|\n| LLM (compose) | _safe_parse_llm_response retries once, then raises (existing retry mechanism) | Celery task retry (max_retries=3) | SynthesisResult validation rejects, retry with feedback |\n| DB (existing page query) | Exception propagates to stage-level handler, triggers retry | Same | N/A |\n\n## Negative Tests\n\n- No existing page for creator+category → falls through to standard synthesis (no compose)\n- Existing page found but zero linked moments → should still compose (empty existing_moments list)\n- Multiple pages match creator+category → uses first, logs warning\n  - Estimate: 1.5h\n  - Files: backend/pipeline/stages.py\n  - Verify: cd /home/aux/projects/content-to-kb-automator && python -c \"from pipeline.stages import _build_compose_user_prompt, _compose_into_existing; print('imports OK')\" && grep -q 'body_sections_format' backend/pipeline/stages.py && grep -q 'TechniquePageVideo' backend/pipeline/stages.py && grep -q 'stage5_compose' backend/pipeline/stages.py\n- [x] **T02: Added 12 unit tests covering compose prompt construction, branching logic, body_sections_format, TechniquePageVideo insertion, and case-insensitive category matching** — Create test_compose_pipeline.py covering compose prompt construction, compose-or-create branching, TechniquePageVideo insertion, and body_sections_format setting.\n\n## Steps\n\n1. Create `backend/pipeline/test_compose_pipeline.py`.\n\n2. Write test fixtures:\n   - Mock KeyMoment objects (using simple namedtuples or dataclasses with .title, .summary, .content_type, .start_time, .end_time, .plugins, .raw_transcript, .id, .technique_page_id, .source_video_id)\n   - Mock TechniquePage object with .id, .title, .slug, .topic_category, .summary, .body_sections, .signal_chains, .plugins, .source_quality, .creator_id\n   - Use `unittest.mock` for DB session and LLM client\n\n3. Test `_build_compose_user_prompt()`:\n   - **test_compose_prompt_xml_structure**: verify output contains `<existing_page>`, `<existing_moments>`, `<new_moments>`, `<creator>` tags\n   - **test_compose_prompt_offset_indices**: with 3 existing moments and 2 new moments, verify existing use [0]-[2] and new use [3]-[4]\n   - **test_compose_prompt_empty_existing_moments**: 0 existing, N new → new moments start at [0]\n   - **test_compose_prompt_page_json**: verify existing page serialized as JSON within `<existing_page>` tags\n\n4. Test compose-or-create branching:\n   - **test_compose_branch_triggered**: mock session.execute to return an existing page + moments for the same creator+category → verify `_compose_into_existing` is called (patch it)\n   - **test_create_branch_no_existing**: mock session.execute to return None for existing page query → verify `_synthesize_chunk` is called instead\n   - **test_category_case_insensitive**: verify query uses func.lower for category matching (inspect the query or test with mixed-case input)\n\n5. Test TechniquePageVideo and body_sections_format:\n   - **test_body_sections_format_v2**: verify pages created by both compose and create paths have body_sections_format='v2'\n   - **test_technique_page_video_inserted**: verify INSERT with on_conflict_do_nothing is executed after page persist\n\n## Must-Haves\n\n- [ ] At least 4 tests for _build_compose_user_prompt covering XML structure, offset math, empty existing, page JSON\n- [ ] At least 2 tests for branching logic (compose triggered vs create fallback)\n- [ ] At least 1 test for body_sections_format = 'v2'\n- [ ] At least 1 test for TechniquePageVideo insertion\n- [ ] All tests pass with `python -m pytest backend/pipeline/test_compose_pipeline.py -v`\n  - Estimate: 1h\n  - Files: backend/pipeline/test_compose_pipeline.py\n  - Verify: cd /home/aux/projects/content-to-kb-automator && python -m pytest backend/pipeline/test_compose_pipeline.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/S04/S04-SUMMARY.md` (compress all task summaries).\n8. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M014/slices/S04/S04-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.

The system is deployed and running on ub01 at `http://ub01:8096`.\n\n### What's Built\n\n- **Transcription pipeline** — Desktop script: video → ffmpeg audio extraction → Whisper large-v3 → timestamped transcript JSON\n- **6-stage LLM extraction pipeline** — Transcript segmentation → key moment extraction → classification/tagging → technique page synthesis → embedding/indexing. Per-stage model routing (chat vs thinking models). Resumable per-video per-stage.\n- **Article versioning** — Pre-overwrite snapshots with pipeline metadata (prompt SHA-256 hashes, model config) for benchmarking extraction quality across prompt iterations.\n- **Review queue UI** — Admin interface for approving/editing/rejecting extracted key moments.\n- **Search-first web UI** — Dark theme with cyan accents. Semantic search (Qdrant), topic/creator browse pages, technique detail pages with signal chain blocks and video source metadata. Search autocomplete with popular suggestions on focus and typeahead on 2+ characters.\n- **Docker Compose deployment** — API, worker, web, watcher, PostgreSQL, Redis, Qdrant, Ollama on ub01 with bind mounts at `/vmPool/r/services/chrysopedia_*`.\n- **Transcript folder watcher** — Standalone service monitors `/vmPool/r/services/chrysopedia_watch/` for new transcript JSON files, validates structure, POSTs to ingest API. Processed files move to `processed/`, failures to `failed/` with `.error` sidecar. Uses watchdog PollingObserver for ZFS reliability.\n- **Prompt template system** — Editable per-stage prompt files with SHA-256 tracking for reproducibility.\n- **Pipeline admin dashboard** — Admin page at `/admin/pipeline` with video list, status badges, retrigger/revoke controls, expandable event log with token usage, collapsible JSON response viewer, and live worker status indicator. Pipeline events instrumented via `PipelineEvent` model (stage, event_type, token counts, JSONB payload).\n- **Technique page 2-column layout** — Prose content (summary + study guide) on left, sidebar (key moments, signal chains, plugins, related techniques) on right at desktop widths. Sticky sidebar. Collapses to single column at ≤768px.\n- **Key moment card redesign** — Cards in sidebar show title prominently on its own line (h3), with source file, timestamp, and content type badge on a clean metadata row below.\n- **Admin navigation dropdown** — Header consolidated: Home, Topics, Creators visible; Admin dropdown reveals Review, Reports, Pipeline. ModeToggle removed from header.\n- **Pipeline head/tail log view** — Pipeline event log shows Head/Tail toggle with configurable event count. Token counts visible per event and per video.\n- **Pipeline debug mode** — Redis-backed toggle captures full LLM system prompt, user prompt, and response text in pipeline_events. Per-stage token summary endpoint for cost/usage analysis.\n- **Debug payload viewer** — Admin UI component for viewing, copying, and exporting full LLM I/O from debug-mode pipeline runs.\n- **Admin UX improvements** — Debug mode toggle, status filter pills, cleaner labels, pruned dead UI elements, review queue cross-links.\n- **Git commit SHA tracking** — Pipeline captures current git commit SHA. Technique page versions display commit hash in metadata.\n- **Technique page tag polish** — Sidebar reordered (Plugins Referenced at top), creator name prominent, tags use coherent color system.\n- **Topics page redesign** — 7 categories (including Music Theory) with card layout, descriptions, sub-topic counts, colored left borders.\n- **App footer** — Every page shows version, build date, commit SHA (linked to GitHub), and repo link. Build-time constants via Vite define with Docker ARG/ENV passthrough.\n"}],"isError":false,"timestamp":1775180021866}}

All pages now get `body_sections_format='v2'` set unconditionally, and a `TechniquePageVideo` row is inserted via `pg_insert` with `on_conflict_do_nothing` for idempotency.\n\nT02 created 12 unit tests across 4 test classes: prompt construction (5 tests for XML structure, offset indices, empty existing moments, page JSON serialization, moment content), branching logic (3 tests using source-code assertions + focused mocks), format/tracking (3 tests for v2 flag, pg_insert usage, INSERT values), and case sensitivity (1 test verifying func.lower on both sides of the category comparison). All 12 pass.","observabilitySurfaces":["INFO log when compose path triggered: 'Stage 5: Composing into existing page ...'","WARNING log when multiple pages match creator+category"],"oneLiner":"Stage 5 now detects existing technique pages by creator+category and branches to a compose path that merges new video content into them, with body_sections_format='v2' and TechniquePageVideo tracking on all pages.","patternsEstablished":["Compose-or-create branching: query existing pages by creator_id + LOWER(category), compose into first match, fall through to standard synthesis otherwise","XML-tagged compose prompt with offset-indexed moments: existing [0]-[N-1], new [N]-[N+M-1]"],"provides":["Compose-or-create branching in stage5_synthesis","body_sections_format='v2' on all technique pages","TechniquePageVideo join table populated for every page+video combination"],"requirementsAdvanced":[{"how":"Stage 5 now composes new video content into existing technique pages instead of overwriting, fulfilling the incremental update aspect of R012","id":"R012"}],"requirementsInvalidated":[],"requirementsSurfaced":[],"requirementsValidated":[],"requires":[{"provides":"Synthesis prompt v5 with nested sections + citations format","slice":"S01"},{"provides":"Compose prompt + test harness validation","slice":"S02"},{"provides":"Data model with body_sections_format column and TechniquePageVideo table","slice":"S03"}],"sliceId":"S04","sliceTitle":"Pipeline Compose-or-Create Logic","uatContent":"## UAT: Pipeline Compose-or-Create Logic\n\n### Preconditions\n- PostgreSQL running with current schema (body_sections_format column on technique_pages, technique_page_videos table)\n- Stage 5 compose prompt file exists at expected path (stage5_compose.txt)\n- At least one creator with processed video data in the database\n\n### Test 1: Fresh synthesis (no existing page)\n**Steps:**\n1.
