Enumerate durable STS identities for parent/type revocation, retain the
operation cutoff, and notify sibling caches for each committed deletion.
Repair missed notifications during periodic object/etcd IAM refresh.
Carry immutable STS tombstones and expiry through the existing IAM revision
protocol and deletion healing. Delayed creation cannot undo revocation,
while unrelated and newly issued keys stay valid. Keep partial failures
visible while propagating the successfully committed deletions.
Cover uncached credentials, warm sibling caches, dropped notifications,
object/etcd backends, reordered replay, concurrent issuance and partial
persistence failure. No new dependencies or authentication-path I/O.

Retain source-ordered tombstones and parent grant boundaries across both IAM backends, cache reloads, and deliberate identity recreation. Reconcile deletions through a versioned, bounded replication protocol with restart-aware acknowledgements.
Cover inherited group grants, STS retention, same-key service recreation, absolute expiration, and failures after the durable commit. Document coordinated upgrades and the remaining consistency boundaries.
