Migration 0014 adds playlists + playlist_tracks. track_id is nullable with ON DELETE SET NULL — tracks can be removed from the library without silently dropping playlist entries; the denormalized snapshot (title/artist/album/duration) keeps the row legible afterwards. UI renders such rows greyed-out. Indexes: playlists by (user_id, updated_at DESC) and a partial public index for cross-user discovery; playlist_tracks partial index on track_id to support the FK SET NULL lookup. Queries provide CRUD + rollup recompute (track_count, duration_sec) + append/remove primitives. Reorder is service-layer orchestrated via raw tx.Exec; no SQL primitive needed.
