Implements the §6.2 enrichment pipeline: embedded tags → Chromaprint
fingerprint → AcoustID lookup. Well-tagged files get correct
artist/album/title offline; the rest are identified via AcoustID
(which also yields a MusicBrainz recording id in one call).
- domain: AudioTags/Fingerprint/RecordingMatch value objects; ports
AudioTagReader, AudioFingerprinter, AcoustIdClient; TrackRepository
.apply_enrichment (gap-fill, never erases) + AlbumRepository.get_or_create
- infrastructure/metadata: MutagenTagReader, FpcalcFingerprinter,
AcoustIdHttpClient (rich meta=recordings+releasegroups, throttled)
- application: MetadataEnrichmentService — tags preferred, AcoustID fills
gaps; resolves artist/album; status enriched/failed; skips manual;
every external step wrapped (graceful degradation)
- workers: enrich_task registered; enqueue_enrich is best-effort and
deferred so the caller's txn commits before the worker reads the row
- wiring: upload enqueues after add; import returns imported_ids and
enqueues post-commit (mid-scan would race the worker); manual
POST /tracks/{id}/metadata/enrich endpoint
- deps: add mutagen (fpcalc/ffmpeg already in the image)
Tests: metadata service orchestration, AcoustID parser, tag helpers.
125 passed; mypy strict + ruff clean.
