## Title

    Version notification registrations and invalidate stale candidates

## Body

    FACT: The examined notification design tracked registration revisions, token rotation, invalidation, and revocation separately from candidate decisions. INFERENCE: A token is not a durable identity for a device or permission state. RECOMMENDATION: Version registrations, compare the candidate revision before transport, and make rotation or revocation invalidate old work without silently replacing it.
