 **Primary/backup testing**: The dual OPC UA test servers (ports 50000 and 50010) in local Docker provide primary/backup endpoint pairs for testing Data Connection Layer failover. Use `docker compose stop opcua` to simulate primary failure and verify automatic failover to the backup.

+**Alarms & Conditions (native alarms)**: The infra OPC PLC server **does** expose OPC UA Alarms & Conditions — a `ConditionRefresh` against its event notifier replays the active condition set and a `SnapshotComplete`, so the native alarm mirror (`IAlarmSubscribableConnection` → `NativeAlarmActor`) can be exercised live. The `OpcUaAlarmLiveSmokeTests.SubscribeAlarms_DeliversConditionRefreshSnapshot` `[SkippableFact]` (Trait `RequiresOpcUa`) round-trips against `opc.tcp://localhost:50000` and asserts the snapshot arrives; it reports **Skipped** (not failed) when the server is unreachable or — on a substitute server that lacks A&C — when no snapshot arrives within the window. The MxAccess Gateway alarm feed (`MxGateway` protocol) requires a live gateway and is verified via the `docker-env2` manual deploy check, not in CI.
