Joseph Doherty	aa8834a231	Phase 3 PR 40 — LiveStackSmokeTests: write-roundtrip + subscribe-receives-OnDataChange against the live Galaxy. Finishes LMX #5 by exercising the IWritable + ISubscribable capability paths end-to-end through the Proxy → OtOpcUaGalaxyHost service → MXAccess → real Galaxy. Two new facts target DelmiaReceiver_001.TestAttribute — the writable Boolean UDA on the TestMachine_001 hierarchy in this dev Galaxy. The user nominated TestMachine_001 (the deployed test-target object) as a scratch surface for live testing; ZB query showed DelmiaReceiver_001 carries one dynamic_attribute named TestAttribute (mx_data_type=1=Boolean, lock_type=0=writable, security_classification=1=Operate). Naming makes the intent obvious — the attribute exists for exactly this kind of integration testing — and Boolean keeps the assertions simple (invert, write, read back). Write_then_read_roundtrips_a_writable_Boolean_attribute_on_TestMachine_001: reads the current value as the baseline (Galaxy may return Uncertain quality until the Engine has scanned the attribute at least once — we don't read into a typed bool until Status is Good), inverts it, writes via IWritable, then polls reads in a 5s loop until either the new value comes back or the budget expires. The scan-window poll (rather than a single read after a fixed delay) accommodates Galaxy's variable scan latency on a fresh service start. Restore-on-finally writes the original value back so re-running the test doesn't accumulate a flipped TestAttribute on the dev box (Galaxy holds UDA values across runs since they're deployed). Best-effort restore — swallows exceptions so a failure in restore doesn't mask the primary assertion. Subscribe_fires_OnDataChange_with_initial_value_then_again_after_a_write: subscribes to the same attribute with a 250ms publishing interval, captures every OnDataChange notification onto a thread-safe ConcurrentQueue (MXAccess advisory fires on its own thread per Galaxy's COM apartment model — must not block it), waits up to 5s for the initial-value callback (per ISubscribable's contract: 'driver MAY fire OnDataChange immediately with the current value'), records the queue depth as a baseline, writes the toggled value, waits up to 8s for at least one MORE notification, then searches the queue tail for the notification carrying the toggled value (initial value may appear multiple times before the write commits — looking at the tail finds the post-write delta even if the queue grew during the wait window). Unsubscribes on finally + restores baseline. Both tests use Convert.ToBoolean(value ?? false) to defensively handle the Boxed-vs-typed quirk in MessagePack-deserialized Galaxy values — depending on the wire encoding the Boolean might come back as System.Boolean or System.Object boxing one. Convert.ToBoolean handles both. Same pattern in OnReadValue's existing usage. WaitForAsync helper does the loop+budget pattern shared by both tests. PR 40 is the code side of LMX #5's final two deferred facts. To actually run them green requires re-executing from a normal (non-admin) PowerShell — the elevated-shell skip from PR 39 fires correctly under bash + sc.exe-context (verified). lmx-followups.md #5 updated to note the new facts + the run command + the one remaining genuine follow-up (alarm-condition fact when an alarm-flagged attribute is deployed on TestMachine_001). Test posture from elevated bash: 7 LiveStackSmokeTests facts discovered (was 5; +2 new), all skip cleanly with the elevation message. Build clean.

Joseph Doherty	8adc8f5ab8	Phase 3 PR 37 — End-to-end live-stack Galaxy smoke test. Closes the code side of LMX follow-up #5 ; once OtOpcUaGalaxyHost is installed + started on the dev box, the suite exercises the full topology GalaxyProxyDriver in-process → named-pipe IPC → running OtOpcUaGalaxyHost Windows service → MxAccessGalaxyBackend → live MXAccess runtime → real deployed Galaxy objects. Never spawns the Host process itself — connects to the already-running service per project_galaxy_host_service.md, which is the only way to exercise the production COM-apartment + service-account + pipe-ACL configuration. LiveStackConfig resolves the pipe name + per-install shared secret from two sources in order: OTOPCUA_GALAXY_PIPE + OTOPCUA_GALAXY_SECRET env vars first (for CI / benchwork overrides), then the service's per-process Environment registry values under HKLM\SYSTEM\CurrentControlSet\Services\OtOpcUaGalaxyHost (what Install-Services.ps1 writes at install time). Registry read requires the test host to run elevated on most boxes — the skip message says so explicitly so operators see the right remediation. Hard-coded secrets are deliberately avoided: the installer generates 32 fresh random bytes per install, a committed secret would diverge from production the moment the service is re-installed. LiveStackFixture is an IAsyncLifetime that (1) runs AvevaPrerequisites.CheckAllAsync with CheckGalaxyHostPipe=true + CheckHistorian=false — produces a structured PrerequisiteReport whose SkipReason is the exact operator-facing 'here's what you need to fix' text, (2) resolves LiveStackConfig and surfaces a clear skip when the secret isn't discoverable, (3) instantiates GalaxyProxyDriver + calls InitializeAsync (the IPC handshake), capturing a skip with the exception detail + common-cause hints (secret mismatch, SID not in pipe ACL, Host's backend couldn't connect to ZB) rather than letting a NullRef cascade through every subsequent test. SkipIfUnavailable() translates the captured SkipReason into Assert.Skip at the top of every fact so tests read as cleanly-skipped with a visible reason, not silently-passed or crashed. LiveStackSmokeTests (5 facts, Collection=LiveStack, Category=LiveGalaxy): Fixture_initialized_successfully (cheapest possible end-to-end assertion — if this passes, the IPC handshake worked); Driver_reports_Healthy_after_IPC_handshake (DriverHealth.State post-connect); DiscoverAsync_returns_at_least_one_variable_from_live_galaxy (captures every Variable() call from DiscoverAsync via CapturingAddressSpaceBuilder and asserts > 0 — zero here usually means the Host couldn't read ZB, the skip message names OTOPCUA_GALAXY_ZB_CONN to check); GetHostStatuses_reports_at_least_one_platform (IHostConnectivityProbe surface — zero means the probe loop hasn't fired or no Platform is deployed locally); Can_read_a_discovered_variable_from_live_galaxy (reads the first discovered attribute's full reference, asserts status != BadInternalError — Galaxy's Uncertain-quality-until-first-Engine-scan is intentionally NOT treated as failure since it depends on runtime state that varies across test runs). Read-only by design; writes need an agreed scratch tag to avoid mutating a process-critical attribute — deferred to a follow-up PR that reuses this fixture. CapturingAddressSpaceBuilder is a minimal IAddressSpaceBuilder that flattens every Variable() call into a list so tests can inspect what discovery produced without booting the full OPC UA node-manager stack; alarm annotation + property calls are no-ops.
