Review R1: - M1 (#609): DriverHostActor.StopChild releases the instance's resilience state before evicting the hub. - m2 (#597): DriverHostActor publishes ShouldServiceAsPrimary() to IDriverPrimaryRoleSource at start and on cluster membership changes (deduped), so the native-ack gate denies in a pair's boot window. - m4 (#601): ApplyCachedArtifact returns false on empty/malformed bytes; the cached revision is not adopted, Direct mode goes Stale (no RUNNING FROM CACHE), FetchAndCache lands Steady-with-no-revision and a re-dispatch of the same revision really applies. - m3 (#603): LocalDbReplicationPolicy splits into CapturesChanges (PeerAddress||ApiKey, registration) and SharesRowsWithPeer (ApiKey && (PeerAddress||SyncListenPort>0), alarm drain gate). - m5 (#618): Program.cs catch-all filters HostAbortedException (design-time tooling). - m6 (Cluster-002): ClusterRoleInfo seeds only Up/WeaklyUp members.
