* test: pin verb parity on lock-arbitration keys through acquire and release Backup clients arbitrate repository ownership by writing and retracting small keys under a fixed prefix and re-probing them, each probe using a different verb. They trust those verbs to agree; a key reported present by one and absent by another makes the client either spin or declare the repository corrupt, and neither shows up as an error on the storage side because each individual answer is locally correct. The keys are written and immediately deleted by version id, which is the cycle that empties a version container, so parity is asserted on both sides of the delete and across repeated re-acquire cycles where residue accumulates. Reports which verbs disagreed rather than just failing. * test: run the reacquire cycle on every lock key, and drain probe bodies
