| `*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 |
| id3v2 WriteTo + manual audio copy for AtomicWrite | `tag.Save()` writes to original file; use `WriteTo(tmp)` + seek past tag + `io.Copy` audio data |
| Snapshot tag size before `id3v2.Open()` | `originalSize` is unexported; read 10-byte ID3v2 header and decode synchsafe size ourselves |
