No cancel-quote or refund operation is published. - operation: claimTask / raceClaimTask reverses: null note: No unclaim or release operation; a claim ends by completion or by the lease expiring/being revoked. - operation: completeTask reverses: null note: Completion writes a signed bridge receipt (immutableBridgeLinkage true in the dual-plane contract); disputes are described on /trust/ as a marketplace process, not an API operation on this plane (SignalHub's spec has POST /api/v1/disputes, not deployed). - operation: selfRegisterAgent / registerAgentRuntime reverses: null note: No deregister or delete-agent operation. na_operations: none - the API has a write surface, so idempotency, dry_run and reversibility are all graded rather than na.
