c76ab8fdee Close all four stability-review 2026-04-13 findings so a failed runtime probe subscription can no longer leave a phantom entry that Tick() flips to Stopped and fans out false BadOutOfService quality across a host's subtree, a silently-failed dashboard bind no longer lets the service advertise a successful start while an operator-visible endpoint is dead, the seven sync-over-async sites in LmxNodeManager (rebuild probe sync, Read, Write, four HistoryRead overrides) can no longer park the OPC UA stack thread indefinitely on a hung backend, and alarm auto-subscribe + transferred-subscription restore no longer race shutdown as untracked fire-and-forget tasks.

0003984c1a Document the Galaxy runtime status feature across the architecture guides so operators and future maintainers can find probe machinery, config fields, dashboard panel, and HealthCheck Rule 2e without having to dig through runtimestatus.md or service_info.md

8f340553d9 Instrument the historian plugin with runtime query health counters and read-only cluster failover so operators can detect silent query degradation and keep serving history when a single cluster node goes down

517d92c76f Scope alarm tracking to selected templates and surface endpoint/security state on the dashboard so operators can deploy in large galaxies without drowning clients in irrelevant alarms or guessing what the server is advertising

c5ed5312a9 Surface historian plugin and alarm-tracking health in the status dashboard so operators can detect misconfiguration and runtime degradation that previously showed as fully healthy 
Wraps the 4 HistoryRead overrides and OnAlarmAcknowledge with PerformanceMetrics.BeginOperation, adds alarm counters to LmxNodeManager, publishes a structured HistorianPluginOutcome from HistorianPluginLoader, and extends HealthCheckService with plugin-load, history-read, and alarm-ack-failure degradation rules.
