The user data cache and the item's in-memory rows were both filled once per replica and never invalidated, so a pod serving a playback tick read its own stale resume position and wrote it back over the position another pod had just saved, silently losing resume points, played state, favourites and ratings. - drop the user item data cache - read single and batched user data from the database on every query - prefetch user data for in-memory sorts and filters so each stays one query - cover the lost update against real PostgreSQL with two manager instances
