- MeshGrpcCommandDialer.RetainOnly (IMeshCommandDialer, default no-op): CentralCommunicationActor
hands the dialer the current endpoint set on every contact refresh, so a renamed host or moved
port releases its cached GrpcChannel and idle HTTP/2 connection instead of living for the
process (R03:1.3).
- IMeshPskProvider.RefreshAsync (default = the old InvalidateAll): MeshPskProvider pre-resolves
every known cluster's key concurrently, bounded like the sync path, and swaps an immutable
snapshot in atomically; a failed read keeps that cluster's previous key. The actor calls it from
ContactsLoaded (after SetKnownClusters, off-actor via PipeTo) instead of InvalidateAll, so the
first ack per cluster per ContactRefreshSeconds no longer blocks a gRPC thread on a 3 s-bounded
store read or gets denied past the bound (R03:3.4).
