Server-031: re-triaged. The recommended gateway-side "skip-while-command-in-flight" guard is already in place at WorkerClient.HeartbeatLoopAsync via WorkerClientOptions.HeartbeatStuckCeiling (default 75s = 5× HeartbeatGrace). Two regression tests pin the behaviour. Recommendation #1 (decouple worker-side _writeLock) is a Worker-module concern (Worker-017 / Worker-023) and out of scope here. Server-032: re-triaged. Recommendation #2 (rich diagnostic) is already in EnqueueWorkerEventAsync, with #3 (overflow grace) absorbed by the TryWrite → WriteAsync-with-timeout fall-through. Test EnqueueWorkerEvent_WhenChannelFullPastTimeout_FaultsWithRichDiagnostic pins the diagnostic string. Recommendation #1 (prose contract in gateway.md / docs) is deferred — outside this pass's edit scope. Server-038 (Security): EventsHub.SubscribeSession's missing per-session ACL is documented with a TODO(per-session-acl) and a <remarks> block explaining the v1 acceptance (any dashboard role can subscribe to any session — non-secret metadata, redacted value logging). The per-session ACL design lands in a follow-up once a session-scoped role exists. Server-039 (Error handling): HubTokenService.Validate now rejects a deserialized payload where both Name and NameIdentifier are null/empty. New test file HubTokenServiceTests.cs covers the regression and five sanity cases. TDD confirmed. Server-040 (Conventions): MapGroupsToRoles gains a precedence comment explaining "full literal match first, leading-RDN fallback; OrdinalIgnoreCase via DashboardOptions.GroupToRole". Documentation-only. Server-041 (Design adherence): EventStreamService.ProduceEventsAsync wraps the broadcaster.Publish call in try/catch (Exception). The producer loop and gRPC stream are no longer at the mercy of the broadcaster's never-throw discipline. New regression test StreamEventsAsync_WhenDashboardBroadcasterThrows_StillYieldsEventsAndDoesNotFaultSession. Server-042 (Performance): DashboardSnapshotPublisher.ExecuteAsync now mirrors AlarmsHubPublisher's reconnect loop — wraps the await foreach in a while-not-cancelled, catches general exceptions, and Task.Delays 5s before retrying. An internal ctor accepts a shorter delay for the test. New test file DashboardSnapshotPublisherTests.cs covers the throw-then-yield reconnect path and the normal-completion case. Server-043 (Documentation): HubTokenService class XML doc gains a <remarks> describing the singleton lifetime, the two consumer scopes (DashboardHubConnectionFactory scoped, HubTokenAuthenticationHandler transient), and the thread-safety contract. Verification: dotnet build src/ZB.MOM.WW.MxGateway.slnx clean (0 warnings / 0 errors); src/ZB.MOM.WW.MxGateway.Tests 486/486 passing.
