Applies exactly the reviewed plan in one transaction: every change and its history entry commit together or not at all. Refuses with `409 STALE_PLAN` when the file, the environment's policies or the referenced actions changed since the plan, and with `400 POLICY_FILE_INVALID` when the plan has errors. The digest is a staleness check, not an authorization. The credential is recorded as the actor on each version.
