bvandeusenandClaude Opus 5.5	fcf5b7e5a8	docs: wanted, dbtest, recommendation and playlists comments say what the code does (#6277) ... The same rewrite as d191a282, for four packages whose comments carried the most history: tuning stories, quotes from the operator, single-install measurements in library_scale.go, and 'used to' accounts of bugs. The constraint each story protected stays as a present-tense reason (why tier 3 is reduced not removed, why the randomised arms take an order seed, why the seed artist is eligible in Songs-like). Comments naming system_cron.go and config.RecommendationConfig, neither of which holds what they claimed, now name the scheduler and internal/recsettings. Checked: non-comment tokens identical to HEAD; gofmt clean. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-23 12:19:15 -04:00
bvandeusenandClaude Opus 4.8	f0c08e7326	feat(taste): mood taste facet — #1534 ... Milestone #160 Opt 2b (mood half of the era+mood option). A fourth taste facet alongside artists + genre tags + eras: signed weights over canonical mood buckets (melancholic / energetic / chill / …) derived from a track's enriched folksonomy tags (#1490). - internal/mood: shared vocabulary — Of(tags) maps folksonomy tags to canonical mood buckets (synonyms collapse). Imported by both the taste builder and the scorer so a track's mood is derived identically. - Migration 0047: taste_profile_moods table + taste_tuning.mood_scale (DEFAULT 0.5). - Build side (internal/taste): Config.MoodScale ([0,1] damper, mirrors EraScale); accumulate folds each play/like's mood buckets at base*MoodScale; persist atomic-replaces the mood rows. - Scorer (internal/recommendation): TasteProfile gains a mood term (own tanh scale + additive 0.12 share, so it never weakens the existing signal when a track has no mood tags). Match now takes the candidate's mood buckets; loaded per candidate (ListTrackTagsForTracks → mood.Of) in the primary similarity loader only — the near-whole-library fallback pool passes nil (mood → 0) to avoid a full-library tag scan. - Tuning lab: mood_scale threaded through recsettings + admin API + web card ("Mood weight" row) + Go/web tests. Coverage is partial (grows with tag enrichment; richer once Last.fm is keyed), so mood is a supplement — neutral for tracks with no mood tags.

bvandeusenandClaude Opus 4.8	40384cc05e	feat(taste): era/decade taste facet — #1530 ... Milestone #160 Opt 2 (era half). A third taste facet alongside artists + genre tags: signed weights over decade buckets ("1990s") derived from albums.release_date, rebuilt daily and scored into the taste match. - Migration 0045: taste_profile_eras table (mirrors taste_profile_tags) + taste_tuning.era_scale column (DEFAULT 0.5). - Build side (internal/taste): Config.EraScale ([0,1] damper, mirrors EnrichedTagScale), accumulate folds each play/like's decade at base*EraScale, persist atomic-replaces the era rows. - Scorer (internal/recommendation): TasteProfile gains an era term (own tanh scale + additive 0.15 share so it never weakens the existing artist/tag signal when a track is undated); candidate queries return album release_date; decadeOf mirrors the builder helper. - Tuning lab: era_scale threaded through recsettings + admin API + web card (auto-renders the new row) + Go/web tests. Mood facet deferred to #1534 (partial enrichment coverage + needs candidate-side enriched-tag loading). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-14 09:01:00 -04:00
bvandeusenandClaude Opus 4.8	aff346c731	feat(taste): phase 2a — apply the taste profile via a TasteMatch scoring term (#796) ... The profile built in phase 1 now changes what gets surfaced. Adds a TasteMatch term to the weighted-shuffle score so candidates are re-ranked by their fit to the user's learned taste (positive draws toward it; negative reflects passive avoidance; 0 at cold start). - recommendation/score.go: ScoringInputs.TasteMatchScore ([-1,+1]) + ScoringWeights.TasteWeight + the term in Score. - recommendation/taste.go: LoadTasteProfile reads the taste_profile_* tables; TasteProfile.Match blends the candidate's artist weight (0.7) and avg genre-tag weight (0.3), each tanh-squashed by a fixed scale so one outlier artist can't compress the rest. Unknown artist/tags and empty profiles → 0 (neutral). - candidates.go: both candidate loaders set TasteMatchScore per candidate, so every Score caller (system playlists incl. You-might-like, radio) becomes taste-aware automatically. - weights: systemMixWeights.TasteWeight = 1.5 (daily mixes are the primary taste surface); config.RecommendationConfig gains taste_weight (default 1.0, lighter — radio is seed-directed) wired into the radio handler. - tests: pure (Match curve incl. saturation/clamp/empty-neutral, Score term add+subtract) + DB round-trip (seed taste rows → Match positive). All green vs real Postgres; existing playlist/radio tests unaffected (empty profile → zero taste effect).
