R-1270 (P2): a restore whose app does not reach running in time is never a success — every restore path returns ErrRestoreNotStarted, the household reads that the data is back but the app has not started yet, one operator alarm; the data stays, the undo copy is kept, a late start turns the record into a success and releases the copy. Red-proved. Commit only.
