 Gaps between STREAMING.md contract and playlist.go/main.ts implementation:
 
-- [ ] **Continuous R2 sync during playout (HIGH)**: `syncLatestToR2()` runs only after FFmpeg exits. Needs per-segment upload via filesystem watch or FFmpeg progress pipe.
-- [ ] **Globally unique segment naming (HIGH)**: Add run/session UUID + monotonic sequence. Currently `strftime` only — collisions possible.
-- [ ] **Atomic manifest publication (MEDIUM)**: Upload to temp key then atomically replace `live/playlist.m3u8`.
-- [ ] **Manifest Cache-Control alignment (LOW)**: Add `must-revalidate` and `s-maxage`/`max-age` split.
-- [ ] **CORS headers on HLS responses (MEDIUM)**: Add `Access-Control-Allow-Origin` to Worker or R2 custom domain.
-- [ ] **Player error recovery (MEDIUM)**: Add `hls.on(Hls.Events.ERROR, ...)` with retries, drift, reconnecting state.
-- [ ] **Health endpoint detail (LOW)**: Add active item, playlist revision, run ID, segment info, R2 pub timestamp.
+- [x] **Continuous R2 sync during playout (HIGH)**: fsnotify watcher uploads segments in real-time (~7s delay)
+- [x] **Globally unique segment naming (HIGH)**: `r-{ISOTIME}/seg-{seq}.m4s` via run ID + monotonic sequence
+- [x] **Atomic manifest publication (MEDIUM)**: Upload to `.tmp`, then `CopyObject` to final key
+- [x] **Manifest Cache-Control alignment (LOW)**: `public, max-age=1, s-maxage=2, must-revalidate`
+- [ ] **CORS headers on HLS responses (MEDIUM)**: Needs Cloudflare R2 CORS config (infrastructure, not code)
+- [x] **Player error recovery (MEDIUM)**: `hls.on(ERROR)` handler with 5x retries, exponential backoff (2s→32s), reconnecting overlay
+- [x] **Health endpoint detail (LOW)**: Added run_id, active_item, playlist_revision, last_segment_seq, last_r2_pub, consecutive_failures, unhealthy detection
 - [x] Source media contract + validation — implemented
