2026-08-09 (continued)

• Completed Phase 1 (test fixtures): documented ffmpeg fixture-generation commands in playlist_test.go header comments (valid_720p30, invalid_h265, invalid_24fps).
• Completed Phase 4 (R2 integration):
  • Enhanced SyncToR2 in playlist.go to set CacheControl + ContentType based on file extension:
    • .m4s, .ts, .mp4, .m4a -> public, max-age=31536000, immutable + video/MP2T
    • .m3u8 -> public, max-age=2 + application/vnd.apple.mpegurl

  • Total frontend tests: 27 passing (2 test files).
• Marked Phase 4 "Document stubs/mocks" done (putObject injection pattern).
• Updated TODO.md: Phase 2 chat tests checked, Phase 4 stubs checked.

2026-08-10 (continued 2)

• Implemented STREAMING.md production-readiness gaps from plan .hermes/plans/2026-08-10_164500-production-readiness.md:
  • Task 1-2: Added runID (ISO timestamp format) and monotonic segSequence for globally unique segment naming (r-{ISOTIME}/seg-{seq}.m4s). Replaced strftime pattern with run ID-based path.
  • Task 2: Added watchAndPublishSegments using fsnotify for real-time per-segment R2 upload (~7s delay). Previously syncLatestToR2() only ran after FFmpeg exit.
  • Task 3: Added publishManifest with atomic CopyObject (temp key → final key) to prevent manifest referencing unconfirmed segments.
  • Task 4: Updated manifestCacheControl from "public, max-age=2" to "public, max-age=1, s-maxage=2, must-revalidate" per STREAMING.md.
  • Task 5: Added hls.on(Hls.Events.ERROR) handler in main.ts with bounded retries (5x), exponential backoff (2s→32s), reconnecting overlay (spinner + text). Added showReconnecting/hideReconnecting functions.
  • Task 6: Enriched HealthHandler with run_id, active_item, playlist_revision, last_segment_seq, last_r2_pub, consecutive_failures. Added "unhealthy" status when R2 publish is stale (>12s).
