- DriverTestConnectE2eTests: 3 scenarios (sim/wrong-port/black-hole) against the Modbus Docker fixture. Sim + wrong-port skip if fixture unreachable; black-hole uses ModbusDriverProbe directly (no fixture). - DriverReconnectE2eTests: message round-trip through AdminOperationsActor cluster singleton — Ok=true + audit write, without live driver side effect. - DriverStatusHubE2eTests: bridge-mocked fallback — spawns DriverStatusSignalRBridge in the harness ActorSystem with a mock IHubContext, publishes DriverHealthChanged to the driver-health DPS topic, asserts store upsert + hub SendAsync call. - DockerFixtureAvailability helper: TCP-connect probe for skip guards. - Moq 4.20.72 added to central package management for hub mocking. - Design doc §8.3 replaced with concrete pre-ship operator runbook.
