// #129 mute: the per-item `muted` flag must persist on PUT /api/assignments/:id, come
// back in the item read (ITEM_SELECT), and reach the device by being included in the
// playlist's published_snapshot (buildSnapshotItems). Before the fix the PUT silently
// dropped `muted`, playlist_items had no such column, and the snapshot never carried it —
// so the dashboard mute toggle was a no-op end to end.
