feat: Phase 3.7 — Polish, PO token handling, docs, deployment verification
...
- PO token handling: _is_po_token_error() detects YouTube bot-detection errors,
invalidates cache on detection, logs warning for retry guidance (2 new tests)
- README: YouTube Live Stream Proxy section with architecture, usage, config, limits
- development_plan: Phase 3 complete, timeline updated, status → Phase 1-3 Complete
- Dockerfile/compose: verified OK (ffmpeg + yt-dlp already present, no new volumes)
- npm build: 1403 modules, production build clean

feat: Phase 3.6 — integration + acceptance tests for YouTube proxy
...
- test_integration_phase3.py: 6 tests
Extract→proxy flow (VOD manifest, VOD segment, live manifest),
cache hit bypasses yt-dlp, upstream 404→502, extract disabled→503
Mocked yt-dlp, real FastAPI TestClient + HLSProxyService
- test_acceptance_phase3_youtube.py: 3 tests
Real YouTube VOD extraction, manifest proxy, segment proxy
Follows master→variant→segment chain, verifies MPEG-TS sync byte
- test_acceptance_phase3_live.py: 3 tests
Real live stream extraction, no #EXT-X-ENDLIST assertion,
cache refresh verification, graceful skip when offline
- 201/201 CI pass (234 backend Phase 1-3, zero Phase 3 regressions)
- Updated plan: 3.6 Complete, 6/7 sub-phases done

feat: Phase 3.5 — YouTube → ASR integration with source toggle
...
- useYouTubeASR.ts: adapted from useVideoASR, captures audio from HTMLAudioElement
(hls.js → <audio> → AudioContext.createMediaElementSource → ScriptProcessorNode → WebSocket)
Play/pause events on videoElement; same return shape as useVideoASR
- LTTPage.tsx: Source toggle (Upload/YouTube tabs), YouTubeInput + YouTubeVideoPlayer
wired with handleExtractSuccess → handleAudioReady → useYouTubeASR
Full Transcript button hidden for YouTube source; unified asr variable
- QueryInput.tsx: no changes needed (already supports partialText/value from any source)
- Tests: 18 new (11 useYouTubeASR, 7 LTTPage integration)
- 189/189 total pass (zero regressions)
- Updated plan: 3.5 marked Complete, 5/7 sub-phases done

feat: Phase 3.4 — YouTube Input + Video Player frontend components
...
- YouTubeInput.tsx: URL input with validation (youtube.com/watch, youtu.be, /live/, /shorts/),
loading/error states, Load Stream button, uses useYouTubeExtract mutation
- YouTubeVideoPlayer.tsx: dual hls.js (video + hidden audio), forwardRef,
thumbnail placeholder until play, LIVE badge, quality capped ≤480p,
onAudioReady callback for ASR hook exposure, dynamic import('hls.js')
- Types: YouTubeFormat, YouTubeStreamResponse interfaces
- API: extractYouTubeStream() — POST /youtube/extract
- Query: useYouTubeExtract() TanStack Query mutation hook
- Tests: 16 new (7 YouTubeInput, 9 YouTubeVideoPlayer)
- 171/171 total pass (zero regressions)
- Updated plan: 3.4 marked Complete, 4/7 sub-phases done

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
