Re-review at 7286d320. -014 (Medium): ReadAtTimeAsync didn't classify StartQuery failures,
so a connection-class failure left a dead connection, re-failed every timestamp, and returned
Success=true with all-Bad (no failover); now resets+fails over via a shared classifier + tests.
-015: refresh stale named-pipe comments to TCP (no wire change). -013 (silent cap truncation,
ties OpcUaServer-002/Core.Abstractions-009) deferred cross-module. NOTE: the SDK-touching tests
are net48 + native aahClientManaged and run only on Windows; macOS verifies build + the SDK-free
subset only.
