Phase Details

Phase 19: WAV Tag Writer

Goal: Users can edit metadata and cover art on WAV files with the same experience as MP3/FLAC Depends on: Nothing (extends existing tag writing pipeline) Requirements: WAV-01, WAV-02, WAV-03, WAV-04, WAV-05, WAV-06 Success Criteria (what must be TRUE):

  1. User can open a WAV file in the single-track editor, change any of the 8 text fields, save, and see the changes persist after re-scanning the library
  2. User can embed, replace, or remove cover art on a WAV file and see the updated artwork in the track list and player
  3. Editing a WAV file's tags does not alter audio playback — the file sounds identical before and after
  4. Existing metadata in the WAV file that wasn't edited (RIFF INFO chunks, bext, cue markers) survives the tag write unchanged
  5. If the app crashes or loses power during a WAV tag write, the original file is intact (not corrupted or truncated) Plans: 2/2 plans complete

Plans:

  • 19-01-PLAN.md — WAV RIFF parser/writer and writeWavTags function
  • 19-02-PLAN.md — WAV tag writer round-trip tests

Phase 20: OGG Vorbis Tag Writer

Goal: Users can edit metadata and cover art on OGG Vorbis files with the same experience as MP3/FLAC/WAV Depends on: Phase 19 (pipeline extension pattern proven) Requirements: OGG-01, OGG-02, OGG-03, OGG-04, OGG-05, OGG-06 Success Criteria (what must be TRUE):

  1. User can open an OGG Vorbis file in the single-track editor, change any of the 8 text fields, save, and see the changes persist after re-scanning the library
  2. User can embed, replace, or remove cover art on an OGG Vorbis file via METADATA_BLOCK_PICTURE and see the updated artwork in the track list and player
  3. Editing an OGG file's tags does not alter audio playback — the file sounds identical before and after
  4. Existing Vorbis Comments that weren't edited (ReplayGain, lyrics, custom fields) survive the tag write unchanged
  5. If the app crashes or loses power during an OGG tag write, the original file is intact (not corrupted or truncated) Plans: 2/2 plans complete

Plans:

  • 20-01-PLAN.md — OGG page parser/writer, Vorbis Comment serializer, writeOggTags, pipeline integration
  • 20-02-PLAN.md — OGG tag writer round-trip tests

Phase 21: Cleanup

Goal: Codebase is clean — no lint warnings or loose ends from tag editing work Depends on: Phase 20 (cleanup after all format work is done) Requirements: CLEAN-01, CLEAN-02 Success Criteria (what must be TRUE):

  1. make lint passes with zero warnings in dbsync.go and tagwriter.go (nlreturn/wsl violations resolved)
  2. Any small issues discovered during v1.2 tag editing milestone are resolved Plans: TBD
