| Inlined migration 8 SQL rather than calling DB struct methods | `runMigrations` receives raw `*sql.DB`, not `*DB` — cannot call receiver methods |
| Deterministic `.yj-tmp` suffix for temp files | Enables reliable orphan cleanup without directory scanning |
| `*slog.Logger` as first param for AtomicWrite | Matches codebase convention — all packages accept logger as first arg |
| go-flac `WriteTo(io.Writer)` for AtomicWrite integration | Pipes directly into temp file callback; avoids `Save(path)` file path conflicts |
| `replaceVorbisComment` as filter+add pattern | flacvorbis has no Set/Replace — must remove existing entries then Add new value |

### Research Flags
- **Phase 16:** go-flac libraries (44 stars) — verify round-trip with edge-case FLAC files early
- ~~**Phase 16:** go-flac libraries (44 stars) — verify round-trip with edge-case FLAC files early~~ — **RESOLVED: 16-02 completed** — 7 round-trip tests pass, dhowden/tag reads what go-flac writes
- **Phase 19:** Custom OGG page rewriter — prototype before committing; consider dropping if too complex
- **Phase 16:** Album artist storage — not currently a separate entity; resolve during planning
