Each of the four telemetry publish seams now also emits its DPS payload into the node-local ITelemetryLocalHub (Phase 5), leaving the existing DistributedPubSub publish untouched: - driver-health AkkaDriverHealthPublisher -> TelemetryItem.Health - resilience DriverResilienceStatusPublisherService -> TelemetryItem.Resilience - alerts ScriptedAlarmHostActor + DriverHostActor (native) -> TelemetryItem.Alarm - script-logs VirtualTagActor + DpsScriptLogPublisher -> TelemetryItem.Script DI services take the hub as a required ctor param; actors take an optional nullable hub threaded through their Props and the real spawn sites (DriverHostActor <- ServiceCollectionExtensions; VirtualTagActor/ScriptedAlarmHostActor <- DriverHostActor), so existing test Props constructions keep compiling and simply do not emit. The hub is a no-op until a gRPC client subscribes, so the emit is safe on every node. Claude-Session: https://claude.ai/code/session_01GASWkNEi68FSCtvr6rLoEW
