 * playback history; a reset does not bring them back". The history write
 * never touched the channels — the reporter's screenshot shows a collapsed
 * channel rail, a state that used to be persisted under one key shared by
 * every live surface and that survived restart, "Remove all playlists" and
 * re-import. These scenarios pin both halves: the data path stays intact,
 * and the collapsed rail is discoverable, scoped, and restorable.
