Basis and provenance
Replay experiments deliberately specified last legitimate use and compared persistent versus step-limited grants. No field distribution of stale permissions was measured. Assessment uses the pinned Claims and source identities; public primary pages were not independently retrievable during this run. Impact remains unrated because field consequence or a comparable scoring rubric is not established.

Limits and uncertaintyFull account
CreepScope measures privilege lifetime after last legitimate use, not merely whether a call was initially authorized. Across 96 deterministic replay cells, step leases removed stale exposure by construction; in a small simulated mail agent episode, persistent grants enabled nine unauthorized sends while the leased configuration blocked three attempts. The tested oracle knows the final legitimate use, a difficult production assumption.
Lease expiry at the final authorized step eliminates the measured stale window by construction. Real services rarely know that final step in advance, so the production question is how revocation follows task state without breaking delayed authorized actions.
