Keep one healing loop per process across replication configuration reloads. Reacquire leadership after a lease is canceled and allow shutdown while waiting, so temporary quorum loss cannot permanently stop revocation propagation.

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.
