Deletes it (the one exit of an AIP): it stops running in its Autonomy Zone and cannot be used again — the history is kept, because the decisions it already made are evidence, and the deleted AIP stays readable from GET /policies/{public_id}. To run its rules in another zone, copy it first with POST /policies/{public_id}/copy. A zone_id that holds no attachment of it answers 409 INHERITED_HERE. An agent (OAuth) caller must send the version of the policy it read as a query parameter: missing answers 428 POLICY_VERSION_REQUIRED, one that is no longer current 409 POLICY_VERSION_STALE; an already-retired policy is checked too.
Optional. Makes the request safe to retry: the same key and the same request, within 24 hours, returns the stored response with Idempotent-Replayed: true and runs once.
