- Custom RIFF parser for WAV: lenient-read/strict-write, ID3v2 chunk at end of file
- WAV writer reuses MP3's applyTextChanges/applyCoverArtChanges for ID3v2 tag manipulation
- WAV test read-back uses bogem/id3v2.ParseReader (dhowden/tag ReadFrom does not support WAV)
- Custom OGG CRC32 with precomputed lookup table (hash/crc32 uses incompatible reflected bit ordering)
- Raw byte preservation for Vorbis Comment entries — [][]byte instead of []string for non-UTF-8 safety
- METADATA_BLOCK_PICTURE + legacy COVERART/COVERARTMIME stripping on all OGG cover art operations

### Last Session
**Date:** 2026-03-19
**What happened:** Executed 19-02-PLAN.md — WAV tag writer tests. Created 7 round-trip tests verifying all WAV requirements (WAV-01 through WAV-06). Used bogem/id3v2 ParseReader for read-back.
**Where we stopped:** Completed 19-02-PLAN.md — Phase 19 complete
**Next action:** `/gsd-plan-phase` for next phase (OGG Vorbis or next milestone phase)
**What happened:** Executed 20-01-PLAN.md — OGG Vorbis tag writer implementation. Created custom OGG page parser/writer with MSB-first CRC32, Vorbis Comment packet serializer with METADATA_BLOCK_PICTURE cover art, and pipeline integration.
**Where we stopped:** Completed 20-01-PLAN.md
