All 5 success criteria from ROADMAP.md are verified. All 8 requirements (WRITE-01, WRITE-02, WRITE-04, WRITE-06, SYNC-01, SYNC-02, SYNC-03, SYNC-04) are satisfied with code evidence and passing tests. + +**Minor note:** The cover art DB sync (updating `cover_art` table, `release_group.cover_art_id`, and thumbnail regeneration after a write) is deferred — the file-level embedding works for both MP3 and FLAC, but the database `cover_art` record is not updated post-write. This is acceptable within the phase goal since WRITE-04 specifically requires file embedding. The DB-level cover art sync can be added when the UI sends cover art data (Phase 17). + +**Test results:** All 17 tests pass (5 MP3, 7 FLAC, 5 pipeline integration).
