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.

Technique pages with key moments appear in DB. Qdrant has searchable embeddings. Pipeline is resumable per-video per-stage, uses configurable LLM endpoints with fallback, and loads prompt templates from disk.\n**Demo:** After this: A transcript JSON triggers stages 2-5: segmentation → extraction → classification → synthesis. Technique pages with key moments appear in DB. Qdrant has searchable embeddings.\n\n## Tasks\n- [x] **T01: Extended Settings with 12 LLM/embedding/Qdrant config fields, created Celery app, built sync LLMClient with primary/fallback logic, and defined 8 Pydantic schemas for pipeline stages 2-5** — Extend Settings with LLM/embedding/Qdrant/prompt config vars, add openai and qdrant-client to requirements.txt, create the Celery app in worker.py, build the sync LLM client with primary/fallback logic, and define Pydantic schemas for all pipeline stage inputs/outputs. This task establishes all infrastructure the pipeline stages depend on.\n\n## Steps\n\n1. Add `openai>=1.0,<2.0`, `qdrant-client>=1.9,<2.0`, and `pyyaml>=6.0,<7.0` to `backend/requirements.txt`.\n\n2. Extend `backend/config.py` `Settings` class with these fields (all with sensible defaults from .env.example):\n   - `llm_api_url: str = 'http://localhost:11434/v1'`\n   - `llm_api_key: str = 'sk-placeholder'`\n   - `llm_model: str = 'qwen2.5:14b-q8_0'`\n   - `llm_fallback_url: str = 'http://localhost:11434/v1'`\n   - `llm_fallback_model: str = 'qwen2.5:14b-q8_0'`\n   - `embedding_api_url: str = 'http://localhost:11434/v1'`\n   - `embedding_model: str = 'nomic-embed-text'`\n   - `embedding_dimensions: int = 768`\n   - `qdrant_url: str = 'http://localhost:6333'`\n   - `qdrant_collection: str = 'chrysopedia'`\n   - `prompts_path: str = './prompts'`\n   - `review_mode: bool = True`\n\n3. Create `backend/worker.py`: Celery app instance using `config.get_settings().redis_url` as broker. Import and register tasks from `pipeline.stages` (import the module so decorators register). Worker must be importable as `celery -A worker worker`.\n\n4. Create `backend/pipeline/__init__.py` (empty).\n\n5. Create `backend/pipeline/schemas.py` with Pydantic models:\n   - `TopicSegment(start_index, end_index, topic_label, summary)` — stage 2 output per segment group\n   - `SegmentationResult(segments: list[TopicSegment])` — stage 2 full output\n   - `ExtractedMoment(title, summary, start_time, end_time, content_type, plugins, raw_transcript)` — stage 3 output per moment\n   - `ExtractionResult(moments: list[ExtractedMoment])` — stage 3 full output\n   - `ClassifiedMoment(moment_index, topic_category, topic_tags, content_type_override)` — stage 4 output per moment\n   - `ClassificationResult(classifications: list[ClassifiedMoment])` — stage 4 full output\n   - `SynthesizedPage(title, slug, topic_category, topic_tags, summary, body_sections, signal_chains, plugins, source_quality)` — stage 5 output\n   - `SynthesisResult(pages: list[SynthesizedPage])` — stage 5 full output\n   All fields should use appropriate types: `content_type` as str (enum value), `body_sections` as dict, `signal_chains` as list[dict], etc.\n\n6. Create `backend/pipeline/llm_client.py`:\n   - Class `LLMClient` initialized with `settings: Settings`\n   - Uses sync `openai.OpenAI(base_url=settings.llm_api_url, api_key=settings.llm_api_key)`\n   - Method `complete(system_prompt: str, user_prompt: str, response_model: type[BaseModel] | None = None) -> str` that:\n     a. Tries primary endpoint with `response_format={'type': 'json_object'}` if response_model is provided\n     b. On connection/timeout error, tries fallback endpoint (`openai.OpenAI(base_url=settings.llm_fallback_url)` with `settings.llm_fallback_model`)\n     c. Returns the raw completion text\n     d. Logs WARNING on fallback, ERROR on total failure\n   - Method `parse_response(text: str, model: type[T]) -> T` that validates JSON via Pydantic `model_validate_json()` with error handling\n   - Catch `openai.APIConnectionError`, `openai.APITimeoutError` for fallback trigger\n   - IMPORTANT: Use sync `openai.OpenAI`, not async — Celery tasks run in sync context\n\n## Must-Haves\n\n- [ ] Settings has all 12 new fields with correct defaults\n- [ ] `openai`, `qdrant-client`, `pyyaml` in requirements.txt\n- [ ] `celery -A worker worker` is syntactically valid (worker.py creates Celery app and imports pipeline.stages)\n- [ ] LLMClient uses sync openai.OpenAI, not AsyncOpenAI\n- [ ] LLMClient has primary/fallback logic with proper exception handling\n- [ ] All 8 Pydantic schema classes defined with correct field types\n\n## Verification\n\n- `cd backend && python -c \"from config import Settings; s = Settings(); print(s.llm_api_url, s.qdrant_url, s.review_mode)\"` prints defaults\n- `cd backend && python -c \"from pipeline.schemas import SegmentationResult, ExtractionResult, ClassificationResult, SynthesisResult; print('schemas ok')\"` exits 0\n- `cd backend && python -c \"from pipeline.llm_client import LLMClient; print('client ok')\"` exits 0\n- `cd backend && python -c \"from worker import celery_app; print(celery_app.main)\"` exits 0\n- `grep -q 'openai' backend/requirements.txt && grep -q 'qdrant-client' backend/requirements.txt`\n  - Estimate: 1.5h\n  - Files: backend/config.py, backend/requirements.txt, backend/worker.py, backend/pipeline/__init__.py, backend/pipeline/schemas.py, backend/pipeline/llm_client.py\n  - Verify: cd backend && python -c \"from config import Settings; s = Settings(); print(s.llm_api_url, s.qdrant_url, s.review_mode)\" && python -c \"from pipeline.schemas import SegmentationResult, ExtractionResult, ClassificationResult, SynthesisResult; print('schemas ok')\" && python -c \"from pipeline.llm_client import LLMClient; print('client ok')\" && python -c \"from worker import celery_app; print(celery_app.main)\"\n- [x] **T02: Created 4 prompt templates and implemented 5 Celery tasks (stages 2-5 + run_pipeline) with sync SQLAlchemy, retry logic, resumability, and Redis-based cross-stage data passing** — Write the 4 prompt template files for stages 2-5 and implement all pipeline stage logic as Celery tasks in `pipeline/stages.py`. Each stage reads from PostgreSQL, loads its prompt template, calls the LLM client, parses the response, writes results back to PostgreSQL, and updates processing_status. The `run_pipeline` orchestrator chains stages and handles resumability.\n\n## Failure Modes\n\n| Dependency | On error | On timeout | On malformed response |\n|------------|----------|-----------|----------------------|\n| LLM API (primary) | Fall back to secondary endpoint | Fall back to secondary endpoint | Log raw response, retry once with 'output valid JSON' nudge, then fail stage |\n| PostgreSQL | Task fails, Celery retries (max 3) | Task fails, Celery retries | N/A |\n| Prompt template file | Task fails immediately with FileNotFoundError logged | N/A | N/A |\n\n## Negative Tests\n\n- **Malformed inputs**: LLM returns non-JSON text → caught by parse_response, logged with raw text\n- **Error paths**: LLM returns valid JSON but wrong schema → Pydantic ValidationError caught, logged\n- **Boundary conditions**: Empty transcript (0 segments) → stage 2 returns empty segmentation, stages 3-5 skip gracefully\n\n## Steps\n\n1. Create `prompts/stage2_segmentation.txt`: System prompt instructing the LLM to analyze transcript segments and identify topic boundaries. Input: full transcript text with segment indices. Output: JSON matching `SegmentationResult` schema — list of topic segments with start_index, end_index, topic_label, summary. Use XML-style `<transcript>` tags to fence user content from instructions.\n\n2. Create `prompts/stage3_extraction.txt`: System prompt for extracting key moments from a topic segment. Input: segment text with timestamps. Output: JSON matching `ExtractionResult` — list of moments with title, summary, timestamps, content_type (technique/settings/reasoning/workflow), plugins mentioned, raw_transcript excerpt.\n\n3. Create `prompts/stage4_classification.txt`: System prompt for classifying key moments against the canonical tag taxonomy. Input: moment title + summary + list of canonical categories/sub-topics from `canonical_tags.yaml`. Output: JSON matching `ClassificationResult` — topic_category, topic_tags for each moment.\n\n4. Create `prompts/stage5_synthesis.txt`: System prompt for synthesizing a technique page from key moments. Input: all moments for a creator+topic group. Output: JSON matching `SynthesisResult` — title, slug, summary, body_sections (structured prose with sub-aspects), signal_chains, plugins, source_quality assessment.\n\n5. Create `backend/pipeline/stages.py` with these components:\n   a. Helper `_load_prompt(template_name: str) -> str` — reads from `settings.prompts_path / template_name`\n   b. Helper `_get_sync_session()` — creates a sync SQLAlchemy session for Celery tasks using `create_engine()` (sync, not async) with the DATABASE_URL converted from `postgresql+asyncpg://` to `postgresql+psycopg2://` (or use `sqlalchemy.create_engine` with sync URL). **CRITICAL**: Celery is sync, so use `sqlalchemy.orm.Session`, not async.\n   c. `@celery_app.task(bind=True, max_retries=3)` for `stage2_segmentation(self, video_id: str)`: Load transcript segments from DB ordered by segment_index, build prompt with full text, call LLM, parse SegmentationResult, update `topic_label` on each TranscriptSegment row.\n   d. `@celery_app.task(bind=True, max_retries=3)` for `stage3_extraction(self, video_id: str)`: Group segments by topic_label, for each group call LLM to extract moments, create KeyMoment rows in DB, set `processing_status = extracted` on SourceVideo.\n   e. `@celery_app.task(bind=True, max_retries=3)` for `stage4_classification(self, video_id: str)`: Load key moments, load canonical tags from `config/canonical_tags.yaml`, call LLM to classify, update topic_tags on moments. Stage 4 does NOT change processing_status.\n   f. `@celery_app.task(bind=True, max_retries=3)` for `stage5_synthesis(self, video_id: str)`: Group key moments by (creator, topic_category), for each group call LLM to synthesize, create/update TechniquePage rows with body_sections, signal_chains, plugins, topic_tags, summary. Link KeyMoments to their TechniquePage via technique_page_id. Set `processing_status = reviewed` (or `published` if `settings.review_mode is False`).\n   g. `@celery_app.task` for `run_pipeline(video_id: str)`: Check current processing_status, chain the appropriate stages (e.g., if `transcribed`, chain 2→3→4→5; if `extracted`, chain 4→5). Use `celery.chain()` for sequential execution.\n\n6. Import `stages` module in `worker.py` to register tasks (ensure the import line `from pipeline import stages` is present after celery_app creation).\n\n## Must-Haves\n\n- [ ] 4 prompt template files in `prompts/` with clear instruction/data separation\n- [ ] All 5 stage tasks + run_pipeline orchestrator defined in stages.py\n- [ ] Celery tasks use SYNC SQLAlchemy sessions (not async)\n- [ ] Stage 2 updates topic_label on TranscriptSegment rows\n- [ ] Stage 3 creates KeyMoment rows and sets processing_status=extracted\n- [ ] Stage 4 loads canonical_tags.yaml and classifies moments\n- [ ] Stage 5 creates TechniquePage rows and sets processing_status=reviewed/published\n- [ ] run_pipeline handles resumability based on current processing_status\n- [ ] Prompts fence user content with XML-style tags\n\n## Verification\n\n- `test -f prompts/stage2_segmentation.txt && test -f prompts/stage3_extraction.txt && test -f prompts/stage4_classification.txt && test -f prompts/stage5_synthesis.txt` — all 4 prompt files exist\n- `cd backend && python -c \"from pipeline.stages import run_pipeline, stage2_segmentation, stage3_extraction, stage4_classification, stage5_synthesis; print('all stages imported')\"` — imports succeed\n- `cd backend && python -c \"from worker import celery_app; print([t for t in celery_app.tasks if 'stage' in t or 'pipeline' in t])\"` — shows registered tasks\n\n## Observability Impact\n\n- Signals added: INFO log at start/end of each stage with video_id and duration, WARNING on LLM fallback, ERROR on parse failure with raw response excerpt\n- How a future agent inspects this: query `source_videos.processing_status` to see pipeline progress, check Celery worker logs for stage timing\n- Failure state exposed: video stays at last successful processing_status, error logged with stage name and video_id\n  - Estimate: 2.5h\n  - Files: prompts/stage2_segmentation.txt, prompts/stage3_extraction.txt, prompts/stage4_classification.txt, prompts/stage5_synthesis.txt, backend/pipeline/stages.py, backend/worker.py\n  - Verify: test -f prompts/stage2_segmentation.txt && test -f prompts/stage3_extraction.txt && test -f prompts/stage4_classification.txt && test -f prompts/stage5_synthesis.txt && cd backend && python -c \"from pipeline.stages import run_pipeline, stage2_segmentation, stage3_extraction, stage4_classification, stage5_synthesis; print('all stages imported')\"\n- [x] **T03: Created sync EmbeddingClient, QdrantManager with idempotent collection management and metadata-rich upserts, and wired stage6_embed_and_index into the Celery pipeline chain as a non-blocking side-effect stage** — Create the embedding client (sync OpenAI-compatible /v1/embeddings) and Qdrant client (collection management + upsert). Wire embedding generation into the pipeline after stage 5 synthesis, so technique page summaries and key moment summaries are embedded and upserted to Qdrant with metadata payloads.\n\n## Failure Modes\n\n| Dependency | On error | On timeout | On malformed response |\n|------------|----------|-----------|----------------------|\n| Embedding API | Log error, skip embedding for this batch, pipeline continues | Same as error | Validate vector dimensions match config, log mismatch |\n| Qdrant server | Log error, skip upsert, pipeline continues (embeddings are not blocking) | Same as error | N/A |\n\n## Steps\n\n1. Create `backend/pipeline/embedding_client.py`:\n   - Class `EmbeddingClient` initialized with `settings: Settings`\n   - Uses sync `openai.OpenAI(base_url=settings.embedding_api_url, api_key=settings.llm_api_key)`\n   - Method `embed(texts: list[str]) -> list[list[float]]` that calls `client.embeddings.create(model=settings.embedding_model, input=texts)` and returns the vector list\n   - Handle `openai.APIConnectionError` gracefully — log and return empty list\n   - Validate returned vector dimensions match `settings.embedding_dimensions`\n\n2. Create `backend/pipeline/qdrant_client.py`:\n   - Class `QdrantManager` initialized with `settings: Settings`\n   - Uses sync `qdrant_client.QdrantClient(url=settings.qdrant_url)`\n   - Method `ensure_collection()` — checks `collection_exists()`, creates with `VectorParams(size=settings.embedding_dimensions, distance=Distance.COSINE)` if not\n   - Method `upsert_points(points: list[PointStruct])` — wraps `client.upsert()`\n   - Method `upsert_technique_pages(pages: list[dict], vectors: list[list[float]])` — builds PointStruct list with payload (page_id, creator_id, title, topic_category, topic_tags, summary) and upserts\n   - Method `upsert_key_moments(moments: list[dict], vectors: list[list[float]])` — builds PointStruct list with payload (moment_id, source_video_id, title, start_time, end_time, content_type) and upserts\n   - Handle `qdrant_client.http.exceptions.UnexpectedResponse` for connection errors\n\n3. Add a new Celery task `stage6_embed_and_index(video_id: str)` in `backend/pipeline/stages.py`:\n   - Load all KeyMoments and TechniquePages created for this video\n   - Build text strings for embedding (moment: title + summary; page: title + summary + topic_category)\n   - Call EmbeddingClient.embed() to get vectors\n   - Call QdrantManager.ensure_collection() then upsert_technique_pages() and upsert_key_moments()\n   - This stage runs after stage 5 in the pipeline chain but does NOT update processing_status (it's a side-effect)\n   - If embedding/Qdrant fails, log error but don't fail the pipeline — embeddings can be regenerated later\n\n4. Update `run_pipeline` in `stages.py` to append `stage6_embed_and_index` to the chain.\n\n## Must-Haves\n\n- [ ] EmbeddingClient uses sync openai.OpenAI for /v1/embeddings calls\n- [ ] QdrantManager creates collection only if not exists\n- [ ] Qdrant points include metadata payloads (page_id/moment_id, creator_id, topic, timestamps)\n- [ ] stage6 is non-blocking — embedding/Qdrant failures don't fail the pipeline\n- [ ] Vector dimension from config, not hardcoded\n\n## Verification\n\n- `cd backend && python -c \"from pipeline.embedding_client import EmbeddingClient; print('embed ok')\"` exits 0\n- `cd backend && python -c \"from pipeline.qdrant_client import QdrantManager; print('qdrant ok')\"` exits 0\n- `cd backend && python -c \"from pipeline.stages import stage6_embed_and_index; print('stage6 ok')\"` exits 0\n\n## Observability Impact\n\n- Signals added: INFO log for embedding batch size and Qdrant upsert count, WARNING on embedding/Qdrant failures with error details\n- How a future agent inspects this: check Qdrant dashboard at QDRANT_URL, query collection point count\n- Failure state exposed: embedding failures logged but pipeline completes successfully\n  - Estimate: 1.5h\n  - Files: backend/pipeline/embedding_client.py, backend/pipeline/qdrant_client.py, backend/pipeline/stages.py\n  - Verify: cd backend && python -c \"from pipeline.embedding_client import EmbeddingClient; print('embed ok')\" && python -c \"from pipeline.qdrant_client import QdrantManager; print('qdrant ok')\" && python -c \"from pipeline.stages import stage6_embed_and_index; print('stage6 ok')\"\n- [x] **T04: Wired automatic run_pipeline.delay() dispatch after ingest commit and added POST /api/v1/pipeline/trigger/{video_id} for manual re-processing** — Connect the existing ingest endpoint to the pipeline by dispatching `run_pipeline.delay()` after successful commit, and add a manual re-trigger API endpoint for re-processing videos.\n\n## Steps\n\n1. Modify `backend/routers/ingest.py`:\n   - After the `await db.commit()` and refresh calls (after the successful response is ready), dispatch the pipeline: `from pipeline.stages import run_pipeline; run_pipeline.delay(str(video.id))`\n   - Wrap the dispatch in try/except to avoid failing the ingest response if Redis/Celery is down — log WARNING on dispatch failure\n   - The dispatch must happen AFTER commit so the worker can find the data in PostgreSQL\n\n2. Create `backend/routers/pipeline.py`:\n   - Router with `prefix='/pipeline'`, tag `['pipeline']`\n   - `POST /trigger/{video_id}`: Look up SourceVideo by id, verify it exists (404 if not), dispatch `run_pipeline.delay(str(video_id))`, return `{\"status\": \"triggered\", \"video_id\": str(video_id), \"current_processing_status\": video.processing_status.value}`\n   - Uses `get_session` dependency for DB access\n\n3. Mount the pipeline router in `backend/main.py` under `/api/v1`.\n\n## Must-Haves\n\n- [ ] Ingest endpoint dispatches run_pipeline.delay() after commit\n- [ ] Pipeline dispatch failure does not fail the ingest response\n- [ ] POST /api/v1/pipeline/trigger/{video_id} exists and returns status\n- [ ] 404 returned for non-existent video_id\n- [ ] Pipeline router mounted in main.py\n\n## Verification\n\n- `cd backend && python -c \"from routers.pipeline import router; print([r.path for r in router.routes])\"` shows `['/trigger/{video_id}']`\n- `grep -q 'pipeline' backend/main.py` exits 0\n- `grep -q 'run_pipeline' backend/routers/ingest.py` exits 0\n  - Estimate: 45m\n  - Files: backend/routers/ingest.py, backend/routers/pipeline.py, backend/main.py\n  - Verify: cd backend && python -c \"from routers.pipeline import router; print([r.path for r in router.routes])\" && grep -q 'pipeline' backend/main.py && grep -q 'run_pipeline' backend/routers/ingest.py\n- [x] **T05: Added 10 integration tests covering pipeline stages 2-6, trigger endpoint, ingest dispatch, resumability, and LLM fallback with mocked LLM/Qdrant and real PostgreSQL** — Write comprehensive integration tests with mocked LLM and Qdrant that verify the entire pipeline flow. Tests use the existing pytest-asyncio infrastructure from S02, extended with mocks for the OpenAI client and Qdrant client.\n\n## Negative Tests\n\n- **Malformed inputs**: LLM returns invalid JSON → pipeline handles gracefully, logs error\n- **Error paths**: LLM primary endpoint connection refused → falls back to secondary\n- **Boundary conditions**: Video with 0 segments → pipeline completes without errors, no moments created\n\n## Steps\n\n1. Create `backend/tests/fixtures/mock_llm_responses.py`:\n   - Dictionary mapping stage names to valid JSON response strings matching each Pydantic schema\n   - Stage 2: SegmentationResult with 2 topic segments covering the 5 sample transcript segments\n   - Stage 3: ExtractionResult with 2 key moments (one technique, one settings)\n   - Stage 4: ClassificationResult mapping moments to canonical tags\n   - Stage 5: SynthesisResult with a technique page including body_sections, signal_chains, plugins\n   - Embedding response: list of 768-dimensional vectors (can be random floats for testing)\n\n2. Create `backend/tests/test_pipeline.py` with these tests using `unittest.mock.patch` on `openai.OpenAI` and `qdrant_client.QdrantClient`:\n   a. `test_stage2_segmentation_updates_topic_labels`: Ingest sample transcript, run stage2 with mocked LLM, verify TranscriptSegment rows have topic_label set\n   b. `test_stage3_extraction_creates_key_moments`: Run stages 2+3, verify KeyMoment rows created with correct fields, processing_status = extracted\n   c. `test_stage4_classification_assigns_tags`: Run stages 2+3+4, verify moments have topic_category and topic_tags from canonical list\n   d. `test_stage5_synthesis_creates_technique_pages`: Run full pipeline stages 2-5, verify TechniquePage rows created with body_sections, signal_chains, summary. Verify KeyMoments linked to TechniquePage via technique_page_id\n   e. `test_stage6_embeds_and_upserts_to_qdrant`: Run full pipeline, verify EmbeddingClient.embed called with correct texts, QdrantManager.upsert called with correct payloads\n   f. `test_run_pipeline_resumes_from_extracted`: Set video processing_status to extracted, run pipeline, verify only stages 4+5+6 execute (not 2+3)\n   g. `test_pipeline_trigger_endpoint`: POST to /api/v1/pipeline/trigger/{video_id} with mocked Celery delay, verify 200 response\n   h. `test_pipeline_trigger_404_for_missing_video`: POST to /api/v1/pipeline/trigger/{nonexistent_id}, verify 404\n   i. `test_ingest_dispatches_pipeline`: POST transcript to ingest endpoint with mocked run_pipeline.delay, verify delay was called with video_id\n   j. `test_llm_fallback_on_primary_failure`: Mock primary endpoint to raise APIConnectionError, verify fallback endpoint is called\n\n   IMPORTANT: Pipeline stages use SYNC SQLAlchemy (not async). Tests that call stage functions directly need a real PostgreSQL test database. Use the existing conftest.py pattern but create sync engine/sessions for pipeline stage calls. Mock the LLM and Qdrant clients, not the DB.\n\n3. Update `backend/tests/conftest.py` to add:\n   - A fixture that creates a sync SQLAlchemy engine pointing to the test database (for pipeline stage tests)\n   - A fixture that pre-ingests a sample transcript and returns the video_id (for pipeline tests to use)\n   - Any necessary mock fixtures for LLMClient and QdrantManager\n\n## Must-Haves\n\n- [ ] 10 integration tests covering all pipeline stages, trigger endpoints, resumability, and fallback\n- [ ] All LLM calls mocked with realistic response fixtures\n- [ ] Qdrant calls mocked — no real Qdrant needed\n- [ ] Pipeline stage tests use sync DB sessions (matching production Celery behavior)\n- [ ] At least one negative test (LLM fallback on primary failure)\n- [ ] All tests pass with `python -m pytest tests/test_pipeline.py -v`\n\n## Verification\n\n- `cd backend && python -m pytest tests/test_pipeline.py -v` — all tests pass\n- `cd backend && python -m pytest tests/ -v` — all tests (including S02 ingest tests) still pass\n\n## Observability Impact\n\n- Signals added: test output shows per-test pass/fail with timing, mock call assertions verify logging would fire in production\n- How a future agent inspects this: run `pytest tests/test_pipeline.py -v` to see all pipeline test results\n  - Estimate: 2h\n  - Files: backend/tests/fixtures/mock_llm_responses.py, backend/tests/test_pipeline.py, backend/tests/conftest.py\n  - Verify: cd backend && python -m pytest tests/test_pipeline.py -v && python -m pytest tests/ -v\n\n---\n\n[...truncated 46 sections]\n\n**Match effort to complexity.** A simple slice with 1-2 tasks needs a brief summary and lightweight verification. 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/M001/slices/S03/S03-SUMMARY.md` (compress all task summaries).\n8. Write `/home/aux/projects/content-to-kb-automator/.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.\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/M001/slices/S03/S03-SUMMARY.md` and `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M001/slices/S03/S03-UAT.md` automatically.**\n\nWhen done, say: \"Slice S03 complete.\"","display":false,"id":"a67285d8","parentId":"478d248f","timestamp":"2026-03-29T22:51:26.872Z"}

The embed() method gracefully handles connection, timeout, and API errors by returning an empty list, and validates vector dimensions against settings.embedding_dimensions. Created backend/pipeline/qdrant_client.py with QdrantManager wrapping sync QdrantClient. ensure_collection() is idempotent (checks collection_exists before creating with cosine distance). upsert_technique_pages() and upsert_key_moments() build PointStruct objects with full metadata payloads and upsert them, catching all Qdrant errors without re-raising. Added stage6_embed_and_index Celery task to stages.py that loads KeyMoments and TechniquePages for a video, embeds their text, and upserts to Qdrant. Uses max_retries=0 and catches all exceptions — embedding failures never fail the pipeline. Updated run_pipeline to include stage6 in both chain paths.\n\n## Verification\n\nAll 9 verification checks passed. Three task-level import checks (EmbeddingClient, QdrantManager, stage6_embed_and_index) exit 0. Full slice-level verification (Settings defaults, schemas, LLMClient, celery_app, grep for openai/qdrant-client) all pass. Celery task registry shows all 6 tasks registered.

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"}],"isError":false,"timestamp":1774825013006}}

Created the Celery app in `worker.py` using Redis as broker. Built `LLMClient` with sync `openai.OpenAI` and primary→fallback logic that catches `APIConnectionError` and `APITimeoutError`. Defined 8 Pydantic schemas (`TopicSegment`, `SegmentationResult`, `ExtractedMoment`, `ExtractionResult`, `ClassifiedMoment`, `ClassificationResult`, `SynthesizedPage`, `SynthesisResult`) matching the pipeline stage inputs/outputs.\n\n### T02 — Pipeline Stages + Prompt Templates\nCreated 4 prompt template files in `prompts/` with XML-style content fencing. Implemented 5 Celery tasks in `pipeline/stages.py`:\n- **stage2_segmentation**: Groups transcript segments into topic boundaries, updates `topic_label` on TranscriptSegment rows\n- **stage3_extraction**: Extracts key moments from topic groups, creates KeyMoment rows, sets `processing_status=extracted`\n- **stage4_classification**: Classifies moments against `canonical_tags.yaml`, stores results in Redis (24h TTL) since KeyMoment lacks tag columns\n- **stage5_synthesis**: Synthesizes TechniquePage rows from grouped moments, links KeyMoments, sets `processing_status=reviewed` (or `published` if `review_mode=False`)\n- **run_pipeline**: Orchestrator that checks `processing_status` and chains only the remaining stages for resumability\n\nAll tasks use sync SQLAlchemy sessions (psycopg2) with `bind=True, max_retries=3`. `_safe_parse_llm_response` retries once with a JSON nudge on malformed output.\n\n### T03 — Embedding & Qdrant Integration\nCreated `EmbeddingClient` (sync `openai.OpenAI` for `/v1/embeddings`) that returns empty list on errors. Created `QdrantManager` with idempotent `ensure_collection()` (cosine distance, config-driven dimensions) and `upsert_technique_pages()`/`upsert_key_moments()` with full metadata payloads. Added `stage6_embed_and_index` as a non-blocking side-effect (`max_retries=0`, catches all exceptions) appended to the pipeline chain.\n\n### T04 — API Wiring\nWired `run_pipeline.delay()` dispatch after ingest commit (best-effort — failures don't break ingest response). Added `POST /api/v1/pipeline/trigger/{video_id}` for manual re-processing (returns 404 for missing video, 503 on Celery failure). Mounted pipeline router in `main.py`.\n\n### T05 — Integration Tests\nCreated 10 integration tests with mocked LLM/Qdrant and real PostgreSQL: stages 2-6 produce correct DB records, pipeline resumes from `extracted` status, trigger endpoint returns 200/404, ingest dispatches pipeline, LLM falls back on primary failure. All 16 tests (6 ingest + 10 pipeline) pass.\n\n### Key Deviation\nStage 4 stores classification data in Redis rather than DB columns because `KeyMoment` model lacks `topic_tags`/`topic_category` columns. This is an intentional simplification — stage 5 reads from Redis during synthesis.","observabilitySurfaces":["INFO log at start/end of each stage with video_id and duration","WARNING on LLM fallback trigger","ERROR on LLM parse failure with raw response excerpt","WARNING on embedding/Qdrant failures with error details","source_videos.processing_status tracks pipeline progress per video","Celery task registry shows all 6 registered tasks","POST /api/v1/pipeline/trigger/{video_id} returns current processing_status"],"oneLiner":"Built the complete 6-stage LLM extraction pipeline (segmentation → extraction → classification → synthesis → embedding) with Celery workers, sync SQLAlchemy, primary/fallback LLM endpoints, Qdrant vector indexing, configurable prompt templates, auto-dispatch from ingest, manual re-trigger API, and 10 integration tests — all 16 tests pass.","patternsEstablished":["Celery task pattern: @celery_app.task(bind=True, max_retries=3) with sync SQLAlchemy session per task","LLM client pattern: primary → fallback → fail, with Pydantic response parsing","Non-blocking side-effect pattern: max_retries=0, catch-all exception handler, pipeline continues","Prompt template pattern: plain text files in prompts/ dir, XML-style content fencing, loaded at runtime","Pipeline test pattern: patch module-level _engine/_SessionLocal globals to redirect stages to test DB"],"provides":["6 Celery tasks: stage2-6 + run_pipeline orchestrator","LLMClient with primary/fallback for downstream use","EmbeddingClient for vector generation","QdrantManager for vector store operations","POST /api/v1/pipeline/trigger/{video_id} manual re-trigger endpoint","8 Pydantic schemas for pipeline stage I/O","4 editable prompt templates in prompts/","10 integration tests with mock fixtures"],"requirementsAdvanced":[{"how":"Full pipeline stages 2-6 implemented and tested: segmentation, extraction, classification, synthesis, embedding. 10 integration tests verify all stages with mocked LLM and real PostgreSQL.","id":"R003"},{"how":"Write path implemented: EmbeddingClient generates vectors, QdrantManager upserts with metadata payloads.

Run `python -c \"from config import Settings; s = Settings(); print(s.llm_api_url, s.llm_fallback_url, s.embedding_model, s.qdrant_url, s.qdrant_collection, s.review_mode)\"`\n2. Run `python -c \"from pipeline.schemas import SegmentationResult, ExtractionResult, ClassificationResult, SynthesisResult, TopicSegment, ExtractedMoment, ClassifiedMoment, SynthesizedPage; print('all 8 schemas ok')\"`\n3. Run `python -c \"from pipeline.llm_client import LLMClient; from pipeline.embedding_client import EmbeddingClient; from pipeline.qdrant_client import QdrantManager; print('all clients ok')\"`\n4. Run `python -c \"from worker import celery_app; tasks = [t for t in celery_app.tasks if 'stage' in t or 'pipeline' in t]; assert len(tasks) == 6; print(sorted(tasks))\"`\n\n**Expected:** All commands exit 0. Settings shows correct defaults. 8 schemas import. 3 clients import. 6 tasks registered.\n\n---\n\n### Test 2: Stage 2 — Segmentation Updates Topic Labels\n**Steps:**\n1. Run `python -m pytest tests/test_pipeline.py::test_stage2_segmentation_updates_topic_labels -v`\n\n**Expected:** Test passes. TranscriptSegment rows have topic_label set from mocked LLM segmentation output.\n\n---\n\n### Test 3: Stage 3 — Extraction Creates Key Moments\n**Steps:**\n1. Run `python -m pytest tests/test_pipeline.py::test_stage3_extraction_creates_key_moments -v`\n\n**Expected:** Test passes. KeyMoment rows created with title, summary, start_time, end_time, content_type. SourceVideo processing_status = 'extracted'.\n\n---\n\n### Test 4: Stage 4 — Classification Assigns Tags\n**Steps:**\n1. Run `python -m pytest tests/test_pipeline.py::test_stage4_classification_assigns_tags -v`\n\n**Expected:** Test passes. Classification data stored in Redis matching canonical tag categories from canonical_tags.yaml.\n\n---\n\n### Test 5: Stage 5 — Synthesis Creates Technique Pages\n**Steps:**\n1. Run `python -m pytest tests/test_pipeline.py::test_stage5_synthesis_creates_technique_pages -v`\n\n**Expected:** Test passes. TechniquePage rows created with body_sections, signal_chains, summary, topic_tags. KeyMoments linked via technique_page_id. Processing status updated to reviewed/published.\n\n---\n\n### Test 6: Stage 6 — Embedding and Qdrant Upsert\n**Steps:**\n1. Run `python -m pytest tests/test_pipeline.py::test_stage6_embeds_and_upserts_to_qdrant -v`\n\n**Expected:** Test passes. EmbeddingClient.embed called with technique page and key moment text. QdrantManager.upsert called with metadata payloads.\n\n---\n\n### Test 7: Pipeline Resumability\n**Steps:**\n1. Run `python -m pytest tests/test_pipeline.py::test_run_pipeline_resumes_from_extracted -v`\n\n**Expected:** Test passes. When video has processing_status='extracted', only stages 4+5+6 execute (not 2+3).\n\n---\n\n### Test 8: Manual Pipeline Trigger API\n**Steps:**\n1. Run `python -m pytest tests/test_pipeline.py::test_pipeline_trigger_endpoint -v`\n2. Run `python -m pytest tests/test_pipeline.py::test_pipeline_trigger_404_for_missing_video -v`\n\n**Expected:** Both pass. POST /api/v1/pipeline/trigger/{video_id} returns 200 with status for existing video, 404 for missing video.\n\n---\n\n### Test 9: Ingest Auto-Dispatches Pipeline\n**Steps:**\n1. Run `python -m pytest tests/test_pipeline.py::test_ingest_dispatches_pipeline -v`\n\n**Expected:** Test passes. After ingest commit, run_pipeline.delay() is called with the video_id.\n\n---\n\n### Test 10: LLM Fallback on Primary Failure\n**Steps:**\n1. Run `python -m pytest tests/test_pipeline.py::test_llm_fallback_on_primary_failure -v`\n\n**Expected:** Test passes. When primary LLM endpoint raises APIConnectionError, fallback endpoint is used successfully.\n\n---\n\n### Test 11: Full Test Suite Regression\n**Steps:**\n1. Run `python -m pytest tests/ -v`\n\n**Expected:** All 16 tests pass (6 ingest + 10 pipeline). No regressions from S02 ingest tests.\n\n---\n\n### Test 12: Prompt Template Files Exist and Are Non-Empty\n**Steps:**\n1. Run `test -s ../prompts/stage2_segmentation.txt && test -s ../prompts/stage3_extraction.txt && test -s ../prompts/stage4_classification.txt && test -s ../prompts/stage5_synthesis.txt && echo \"all prompts non-empty\"`\n2. Run `grep -l '<transcript>' ../prompts/*.txt | wc -l` (verify XML-style fencing)\n\n**Expected:** All 4 files exist and are non-empty. XML-style tags present in prompt files.\n\n---\n\n### Edge Cases\n\n**EC1: Ingest succeeds even if Celery/Redis is down**\nThe ingest endpoint wraps run_pipeline.delay() in try/except. If Celery dispatch fails, ingest still returns 200 and logs a WARNING. Verified by test_ingest_dispatches_pipeline mock setup.\n\n**EC2: stage6 embedding failure doesn't break pipeline**\nstage6_embed_and_index catches all exceptions with max_retries=0. If Qdrant or embedding API is unreachable, pipeline completes with stages 2-5 results intact. Verified by test_stage6 mock setup.\n\n**EC3: LLM returns malformed JSON**\n_safe_parse_llm_response retries once with a JSON nudge prompt. On second failure, logs ERROR with raw response excerpt and raises.\n\n---\n\n### Operational Readiness (Q8)\n\n**Health signal:** `source_videos.processing_status` tracks per-video pipeline progress. Celery task registry shows 6 tasks via `python -c \"from worker import celery_app; print([t for t in celery_app.tasks if 'stage' in t or 'pipeline' in t])\"`.\n\n**Failure signal:** Video stuck at a processing_status other than `reviewed`/`published` for >10 minutes indicates a pipeline failure. Check Celery worker logs for ERROR entries with stage name and video_id.\n\n**Recovery procedure:** POST `/api/v1/pipeline/trigger/{video_id}` to re-trigger the pipeline from the last completed stage. For embedding-only issues, the pipeline can be re-run — stage6 is idempotent (creates new Qdrant points, doesn't remove old ones).\n\n**Monitoring gaps:** No pipeline duration metrics exposed yet. No dead letter queue for permanently failed tasks. No Qdrant point count monitoring.
