- KVReplicaSet: seed, apply, local scan, diff against the source, sync meta - KVOutbox: persisted offline queue with in-order replay (load() resumes it) - utils: KeyRange (also used for server authorization), KeyCounter, SerialQueue (also used by KVStorageHttp and the event-sourced store), RetryTimer (separate timers for sync and replay; previously one shared timer could cancel the other's retry) The composite now only orchestrates. Behaviour unchanged; new unit tests for the building blocks and the outbox.
