#8589 Classic remoting: graceful shutdown's full socket close can RST on Windows and the peer loses the last frames (lost ClusterSingleton HandOverDone)

#8191 Akka.TestKit.Xunit (v3): base.DisposeAsync() unreachable from derived IAsyncLifetime — silently leaks ActorSystems

#8583 Cluster.Sharding: a coordinator singleton hand-over stops the node's own ShardRegion even when the node stays in the cluster, and the region never comes back

#8585 ClusterSingletonManager: OldestChangedBuffer can keep a stale entry when a member's up-number changes, because Remove on the age-ordered set uses a comparer that no longer finds it

#8549 Scheduler runs on the CLR thread pool on .NET 6+: a jammed pool stops every timer in the process (deprioritized)

#8565 TestKit: a zero-count EventFilter inside Within runs the block to its own deadline, and WithinAsync's abandon timer ignores epsilon

#8572 Cluster.Sharding: a Shard restart drops its buffered messages with no dead letter

#8568 ClusterSingletonProxy logs a false "failed to find an associated singleton" warning and publishes a spurious Timeout on every start

#8562 Artery: the shutdown flush logs "finished writing" when every outbound stream faulted

#8555 Artery: no RemoteMetricsExtension, so log-frame-size-exceeding is silently inert

#8551 Artery: implement ActorSystemTerminating and its ack so peers quarantine a departing UID at once

#8550 Artery: ordinary-lane HandshakeReq rides the control queue and can time out on a healthy connection

#8483 TestKit: WithinAsync swallows the block's failure when the deadline wins the race

#8508 ClusterClient: ReconnectTimeout timer leaked per message during Establishing can kill a healthy client on reconnect

#8481 DDataClusterShardingLeavingSpec: entity-incarnation assertion races shard rebalancing under the bounded allocation default

#8496 Artery: first ordinary message lost when the peer connects first - outbound handshake self-completes without sending HandshakeReq

#8507 Artery: restart-path handshake completion can anchor to the peer's Req instead of our own round trip

#8506 Artery: SO_RCVBUF/SO_SNDBUF hardcoded at 1 MiB per socket, not configurable like classic remoting

#8505 Artery: no idle outbound stream reaping - sockets accumulate toward all-to-all in large clusters

#8501 ShardRegion silently drops messages delivered during shard hand-off despite having a buffer

#8497 StressSpec churn: blocking Shutdown starves the churn host's heartbeats on 2-vCPU agents until SBR downs it (TestKit lacks ShutdownAsync)

#8474 Artery: no shutdown flush - outbound messages accepted before termination are dropped

#8467 Akka.Cluster: removed member resurrected by gossip merge, permanently blocking convergence

#4363 Enhancement: create ActorTaskScheduler overload that schedules Task to dispatcher without blocking current actor

#5103 ddata durable store may grow forever
