Woody ef10b937cf feat: Sub-Phase 8.0 — config & enums for Q&A-pair chunking strategy 
Backend:
- Add 6 Q&A chunking config fields to Settings (default_chunking_strategy,
  qa_vision_enabled, qa_max_chunk_tokens, qa_structure_model,
  qa_include_internal_refs, qa_cache_vision_results)
- Define ChunkingStrategyType Literal + VALID_CHUNKING_STRATEGIES frozenset
- Add strategy field to IngestResponse (default token, non-breaking)
- Add IngestRequest model with strategy param
- Update .env.example with new env vars

Frontend:
- Add ChunkingStrategy type ('token' | 'question')
- Extend IngestResponse, DocumentInfo, ChunkInfo with Q&A fields

Tests:
- test_qa_chunking_config_defaults — all defaults verified
- test_qa_chunking_config_from_env — env var overrides verified

Plan fix: renamed qa_verification_model → qa_structure_model to match
LLM-first architecture

Woody 284028bb1f feat: Phase 3.1 + 3.2 — YouTube config infra and URL extraction 
Phase 3.1 — Configuration & Infrastructure:
- Add youtube_proxy_enabled, yt_dlp_timeout, yt_dlp_cache_ttl config fields
- Add yt-dlp and hls.js dependencies
- Create models/youtube.py (request/response schemas)
- Create service stubs (youtube_service, hls_proxy)
- Create router stub and register in main.py
- 11 config tests

Phase 3.2 — YouTube URL Extraction:
- yt-dlp wrapper with async extraction (run_in_executor)
- Format selection: ≤480p video-only + highest-bitrate audio (VOD)
- Combined format fallback: same URL for live streams
- In-memory URL cache: 5min TTL live, 30min VOD
- lru_cache singleton service for cache persistence
- Error handling: DownloadError → 200 with error field
- 18 extract tests, 82/82 total pass (zero regressions)

Real-URL verified: VOD (5bF3tkO5jAA) 24 formats, Live (fN9uYWCjQaw) 6 HLS

Woody f4b404f27d feat(db): Phase 3.1 — SQLite infrastructure (prompts.db + history.db) 
- Add sqlite_db.py with dual-DB connection factories (WAL mode, foreign keys)
- init_prompts_db() creates system_prompt_profiles + system_prompts tables
- init_history_db() creates query_history table + created_at index
- seed_default_profiles() inserts 3 profiles (A/B/C) x 3 steps each
- All 3 profiles start with identical seed templates; Profile A active
- Add prompts_db_path + history_db_path to config (./data/ default)
- Startup init in main.py creates data/ dir, inits both DBs, seeds profiles
- Add PROMPTS_DB_PATH + HISTORY_DB_PATH to .env.example
- Add data/ to .gitignore
- 17 new tests in test_phase3_sqlite_db.py (all passing)
