bvandeusenandClaude Opus 5.5	1d4ef1a23f	docs: query comments say what each query selects and why, not how it came to be (#6277) ... Rewrites the internal/db/queries comments to rule 32 and regenerates dbq, whose doc comments and embedded SQL carry them. The bugs behind the tiered mixes, the md5 order seed, the score bands and the round-robin arms are restated as the constraint each one enforces; counts from one library and stale cross-references are gone.

bvandeusenandClaude Opus 4.8	c7adf2c87a	fix(recommendation): broaden You-might-like fallback to liked album/track artists (#790) ... The fallback pulled artists only from explicit artist-likes (general_likes_artists), but most users like albums and tracks far more than artists — so the artists row still came up thin (a couple of tiles) even with a rich library, while the albums row filled fine. Broaden both fallbacks to "entities you've shown affinity for": - artist fallback = explicit artist-likes ∪ artists of liked albums ∪ artists of liked tracks. - album fallback = explicit album-likes ∪ albums of liked tracks. New dedicated queries (ListYouMightLike{Artist,Album}FallbackForUser) replace the narrow Rediscover-fallback reuse; same projection so the Go layer still converts directly. (Aliased + fully-qualified the UNION arms — sqlc merges UNION scopes, so unqualified user_id was ambiguous across the three like tables.) Test: 12 liked TRACKS by distinct artists, no artist-likes → the artist row now fills from their artists (was empty before).

bvandeusenandClaude Opus 4.8	fdd14ef04c	feat(server): "You might like" album/artist Home rows (#790) ... Surface in-library albums/artists the listener doesn't actively spin but is predicted to enjoy, derived from the same similarity + like-weighted candidate engine that powers For-You — rolled up from track scores to album/artist granularity. Built in the daily 3am BuildSystemPlaylists pass, atomic-replaced alongside the system playlists, and read back by /api/home (+ /api/home/index). Cold-start gate: skips generation entirely below 20 distinct unskipped tracks AND 5 distinct artists, so a thin profile ships empty rows rather than near-random tiles. - migration 0034: you_might_like_albums / you_might_like_artists (id+rank, CASCADE, per-user rank index). - playlists/you_might_like.go: cold-start gate + similarity roll-up (sum-of-top-3 aggregation, per-artist album cap, daily-rotating via the same userIDHash jitter as For-You) + atomic-replace persist in the tx. - recommendation/home.go: two new HomePayload sections with read-time cross-section dedup vs Most Played / Rediscover / Last Played, trimmed to 10 each. - api: you_might_like_albums / you_might_like_artists on /api/home and /api/home/index, reusing albumRefFrom / artistRefFromCovered. - tests: pure roll-up/aggregation/cap unit tests + DB-backed gate, sufficiency, and atomic-replace tests (all green vs real Postgres).
