cover_handler.py: - _download_image(): shared helper replaces duplicated download logic - download_back_cover(): fetches back cover from MusicBrainz CAA (/back endpoint), saves as back.jpg; skips if already present - _itunes_cover_url() / download_itunes_cover(): iTunes Search API (no auth), requests 600x600 artwork; fallback after Discogs - _lastfm_cover_url() / download_lastfm_cover(): Last.fm album.getinfo (LASTFM_API_KEY env var); last cover fallback, skips placeholder images - resolve_cover(): extended with iTunes → Last.fm fallback chain metadata_resolver.py: - _discogs_get_tracklist(): fetches full Discogs release via REST API, parses tracklist[] including heading-based disc detection - _lastfm_tracklist(): fetches Last.fm album.getinfo tracks (LASTFM_API_KEY) - resolve(): uses Discogs tracklist → Last.fm tracklist as fallback when MusicBrainz returns no tracks; LASTFM_API_KEY added to env var block music_enricher.py: - process_album(): calls download_back_cover() after execute_album() when MBID known New cover priority: local → MusicBrainz front → Discogs → iTunes → Last.fm New tracklist priority: local → YouTube → MusicBrainz → Discogs → Last.fm → OCR Test suite: 29 → 33 tests (all pass) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
