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.
