  "description": "Immutable exact review of operator choices and owner facts. preview/digest is JCS SHA-256 over this object without preview/ref and preview/digest; preview/ref is corpus-task-pack-turn:<digest>. Runtime checks equality, positive validity no longer than 300 seconds, and the Room expiry ceiling. These times bound approval, not an inference turn. Pins are observations, not authority; every mutation must resolve current owners.",
