- Topic-name drift fix: DriverHealthChanged.TopicName and DriverControlTopic.Name now live on the message contracts in Commons. AkkaDriverHealthPublisher, DriverStatusSignalRBridge, DriverHostActor, and AdminOperationsActor all delegate to the single constant so a rename can't silently desynchronise publisher and subscriber. - DriverStatusPanel._opResultClearTimer switched from System.Timers.Timer to System.Threading.Timer + awaited DisposeAsync. Prevents an in-flight 8s clear-callback from invoking StateHasChanged on a component whose hub has already been released. - PublishHealthSnapshot deduplicates against the last published (state, lastSuccess, lastError, errorCount) fingerprint. The 30s heartbeat no longer floods the SignalR layer with identical Healthy snapshots — newly-joined clients still warm up via the snapshot store on JoinDriver.
