bvandeusenandClaude Fable 5	48f288e2e5	feat(mixes): tiered rebuilds for New for you + First listens (rule #131) ... Both mixes move from a single hard eligibility rule to the tiered ladder, with their tier stamped onto playlist_tracks.pick_kind via the #1270 provenance pipeline. New for you (#1267) — consume on play, degrade by stepping back: - "Consumed" = any track attempted >=30s; played albums leave the mix at the next build instead of crowding it until the calendar window expires. - Tier 1: unconsumed albums added <30d by direct-affinity artists. Tier 2: unconsumed affinity albums from the wider 30-90d window — added while you weren't looking. Tier 3: any unconsumed album added <90d, newest first. First listens (#1268) — track-level "attempted" threshold: - A 2-second accidental brush no longer disqualifies a whole album; "attempted" is duration_played_ms >= 30000 per track. - Tier 1: albums with zero attempted tracks. Tier 2: barely-attempted albums (<=25% of tracks reached 30s), minus the attempted tracks themselves. The artist-affinity ordering signal also moves to the >=30s definition so skip-only contact doesn't read as trust. Producer plumbing: fetch adapters map the tier column onto pick kinds, finishMix propagates PickKind into the persisted candidates, and rotateForDay now rotates within contiguous same-pick-kind blocks so daily rotation can't hoist tier-3 filler above tier-1's exact fits (untiered pools are one block — original behavior).

bvandeusenandClaude Fable 5	2be07ef271	fix(mixes): close three intent gaps found in the system-playlists audit ... Three discovery-mix defects from the intent audit (Scribe note #1254), all sharing the same root pattern — skips treated as non-events: - Deep Cuts (#1257): eligibility counted only unskipped plays, so a track skipped twice with zero completed listens read as "barely heard" and kept being re-offered. Tracks with >=2 skips no longer qualify; a single accidental skip doesn't banish. - Rediscover (#1258): a skip on a rediscover-sourced play — the user explicitly declining the resurfacing invitation — changed nothing, so declined tracks re-qualified the next day forever. Such tracks now sit out 90 days. - On This Day (#1256): day-of-year distance used plain ABS, so Dec 28 vs Jan 3 read as 359 days apart and the window silently gutted itself for ~3 weeks around every New Year. Now circular (LEAST(d, 365-d)), anchored on the build-date parameter instead of now() so it's testable and consistent with the mix's daily determinism.

bvandeusenandClaude Fable 5	4b150a277e	fix(recommendation): Rediscover no longer ships a one-song playlist (#1246) ... Confirmed against prod: exactly one track (17 plays, cold since May 21) met the c>=5 + 30d-cold bar, and three process defects turned that into a 1-track playlist instead of the locked placeholder. - ListRediscoverTracks: collapse the two-tier UNION into one blended pool. The old shallow-tier gate (WHERE NOT EXISTS deep) was all-or-nothing — one 6-month row suppressed the entire 30-day tier — and deep was a strict subset of shallow anyway. Eligibility drops to >=3 non-skip plays (on a weeks-old history the >=5-play tracks are precisely the ones still in rotation); ordering prefers >=6mo cold, then >=5 plays, then raw count. - Minimum viable mix floor for all five discovery mixes: below minLen (15; 5 for the album-coherent NewForYou/FirstListens) the variant is withheld so Home renders the 'listen more to unlock' placeholder instead of a mix that reads as built-wrong. - /api/events: clamp client-supplied 'at' to [user.created_at, now+5m]. Unbounded client clocks could write arbitrarily old plays and poison the 6-month ordering (prod data verified clean — no scrub needed).

bvandeusenandClaude Opus 4.7	2e7b81fdfe	fix(playlists): robust For-You seed + deep fill; young-library mix fallbacks ... For-You silently vanished after ~7 days of not listening (seed query required a non-skip play in the last 7 days) and capped at ~40 on self-hosted libraries with no ListenBrainz similarity data. - PickTopPlayedTracksForUser: tiered seed — last 30d top plays, else all-time top plays, else liked tracks. For-You only disappears now if the account has zero plays AND zero likes. - produceForYou uses deeper candidate source limits (raised random/ tag/similar K) so it reaches ~100 even with empty lb_similar / similar_artists; richer when LB enrichment is present. - Rediscover: tiered — 6-month-dormant, else ≥5-play 30-day-dormant. - On This Day: floor 60→30 days, window ±7→±10 doy; still skips cleanly (no rows → no playlist) on insufficient history.

bvandeusenandClaude Opus 4.7	c7ee0871a5	feat(playlists): #411 R3 — five discovery mixes (#419-423) ... Each is one candidate query + one registry entry; zero client work (R2 made tiles/refresh/shuffle generic, all are singleton kinds so web's server `refreshable` flag and Flutter's derived getter both light up automatically). - deep_cuts (#419): <=2-play tracks from liked / heavily-played artists; diversity-capped. - rediscover (#420): >=5-play tracks not heard in 6 months, by historical affection. - new_for_you (#421): tracks from albums added <=30d whose artist the user likes/plays; album-coherent (no cap). - on_this_day (#422): tracks played within ±7 day-of-year in prior windows (>60d ago), weighted by play count. - first_listens (#423): never-played albums, tiered liked-artist → played-artist → rest; album-coherent. system_mixes.go producers mirror the Discover model (SQL gives the ranking; finishMix caps+truncates to 100 to match For-You/Discover shuffle depth; album-coherent mixes skip the cap). Builder query failure is non-fatal (logged, yields no playlist) like Discover. Existing system_test existence checks are unaffected. Closes the #411 system-playlists-v2 umbrella's new-types thread.
