Browse Source 
Backend:
- app.ts: switch shared pg.Client to pg.Pool with per-transaction clients (#205)
- v2.routes.ts: replace plan instead of appending on replan, fixing self-duplication (#206)
- session-director: populate recentExclusions, per-candidate ranking, batch repetition checks (#209/#211/#213/#215 + minor)
- db.service.ts: claim-fusion watermark, legacy recommendation_batch engine removed (#216/#219/#232)
- app.ts: drop test enqueue-job endpoint (#234)

Frontend:
- AudioEngine/Vibe/usePlaybackStore: dedupe completed feedback, gate feedback to vibe sessions, End Vibe stops playback, Keep toast, shuffle played-set (#207/#236/#237/#238/#239/#240)
