The taste recompute's tag facet now unions the cached track_tags (MusicBrainz/Last.fm folksonomy tags) alongside raw ID3 genre, so a coarse "Rock" gains "post-punk / shoegaze / melancholic". - taste_profile.sql: ListPlayEngagementInputsForUser + ListLikedTrackTasteInputsForUser now return track_id to key the enriched-tag lookup. - accumulate(): for each play, fold its track's enriched tags weighted by engagement × tag.weight × EnrichedTagScale; for each liked track, by the tag-like bonus × tag.weight × scale. A track with no cached tags contributes genre only (graceful). - New Config.EnrichedTagScale (default 0.5) — enriched tags augment the ID3 signal without swamping it; 0 = genre-only. Flows through recsettings.TasteConfig() (starts from DefaultConfig). Promoting it into the admin tuning lab is a small follow-up. Unit-tested the pure foldEnrichedTags helper (overlap accumulation + scale=0 disable). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
