- All 9 enrichment workers: stop auto-retrying 'error' status items (was infinite loop)
Only 'not_found' items retry after configured days; errors require manual full refresh
- Cover art dedup: check both 'pending' AND 'resolved' findings to prevent recreation
- Cover art scanner: top-level Spotify rate limit check skips Spotify entirely when
banned, falls back to iTunes/Deezer only, logs once instead of spamming 429s
Pending count queries included NULL-ID rows that _get_next_item filters
out, so pending stayed > 0 even when no processable items remained.
Workers reported running instead of idle, UI never turned green. Added
AND id IS NOT NULL to _count_pending_items across all 9 workers to
match the _get_next_item filter.
Workers would endlessly match the same track because UPDATE WHERE id =
NULL matches 0 rows in SQL. Added AND id IS NOT NULL to all enrichment
queries (individual, batch EXISTS, and batch fetch) across all 9
workers. Also added process-level guard for belt-and-suspenders safety.
Fix Deezer get_track → get_track_details method name mismatch.
Users can now choose between iTunes/Apple Music and Deezer as their free
metadata source in Settings. Spotify always takes priority when authenticated;
the fallback handles all lookups when it's not.
Core changes:
- DeezerClient: full metadata interface (search, albums, artists, tracks)
matching iTunesClient's API surface with identical dataclass return types
- SpotifyClient: configurable _fallback property switches between iTunes/Deezer
based on live config reads (no restart needed)
- MetadataService, web_server, watchlist_scanner, api/search, repair_worker,
seasonal_discovery, personalized_playlists: all direct iTunesClient imports
replaced with fallback-aware helpers
Database:
- deezer_artist_id on watchlist_artists and similar_artists tables
- deezer_track_id/album_id/artist_id on discovery_pool and discovery_cache
- Full CRUD for Deezer IDs: add, read, update, backfill, metadata enrichment
- Watchlist duplicate detection by artist name prevents re-adding across sources
- SimilarArtist dataclass and all query/insert methods handle Deezer columns
Bug fixes found during review:
- Similar artist backfill was writing Deezer IDs into iTunes columns
- Discover hero was storing resolved Deezer IDs in wrong column
- Status cache not invalidating on settings save (source name lag)
- Watchlist add allowing duplicates when switching metadata sources
Add Deezer as a third metadata enrichment source. Enriches tracks with BPM and explicit flags, albums with
record labels, explicit flags, and type classification (album/single/EP), and backfills artwork and genres across
all entities. Includes background worker with priority queue, rate-limited API client, database migration, server
endpoints, and UI button with purple-themed status tooltip.
