Phase 2 — port MXAccess COM client to Galaxy.Host + MxAccessGalaxyBackend (3rd IGalaxyBackend) + live MXAccess smoke + Phase 2 exit-gate doc + adversarial review. The full Galaxy data-plane now flows through the v2 IPC topology end-to-end against live ArchestrA.MxAccess.dll, on this dev box, with 30/30 Host tests + 9/9 Proxy tests + 963/963 solution tests passing alongside the unchanged 494 v1 IntegrationTests baseline. Backend/MxAccess/Vtq is a focused port of v1's Vtq value-timestamp-quality DTO. Backend/MxAccess/IMxProxy abstracts LMXProxyServer (port of v1's IMxProxy with the same Register/Unregister/AddItem/RemoveItem/AdviseSupervisory/UnAdviseSupervisory/Write surface + OnDataChange + OnWriteComplete events); MxProxyAdapter is the concrete COM-backed implementation that does Marshal.ReleaseComObject-loop on Unregister, must be constructed on an STA thread. Backend/MxAccess/MxAccessClient is the focused port of v1's MxAccessClient partials — Connect/Disconnect/Read/Write/Subscribe/Unsubscribe through the new Sta/StaPump (the real Win32 GetMessage pump from the previous commit), ConcurrentDictionary handle tracking, OnDataChange event marshalling to per-tag callbacks, ReadAsync implemented as the canonical subscribe → first-OnDataChange → unsubscribe one-shot pattern. Galaxy.Host csproj flipped to x86 PlatformTarget + Prefer32Bit=true with the ArchestrA.MxAccess HintPath ..\..\lib\ArchestrA.MxAccess.dll reference (lib/ already contains the production DLL). Backend/MxAccessGalaxyBackend is the third IGalaxyBackend implementation (alongside StubGalaxyBackend and DbBackedGalaxyBackend): combines GalaxyRepository (Discover) with MxAccessClient (Read/Write/Subscribe), MessagePack-deserializes inbound write values, MessagePack-serializes outbound read values into ValueBytes, decodes ArrayDimension/SecurityClassification/category_id with the same v1 mapping. Program.cs selects between stub|db|mxaccess via OTOPCUA_GALAXY_BACKEND env var (default = mxaccess); OTOPCUA_GALAXY_ZB_CONN overrides the ZB connection string; OTOPCUA_GALAXY_CLIENT_NAME sets the Wonderware client identity; the StaPump and MxAccessClient lifecycles are tied to the server.RunAsync try/finally so a clean Ctrl+C tears down the COM proxy via Marshal.ReleaseComObject before the pump's WM_QUIT. Live MXAccess smoke tests (MxAccessLiveSmokeTests, net48 x86) — skipped when ZB unreachable or aaBootstrap not running, otherwise verify (1) MxAccessClient.ConnectAsync returns a positive LMXProxyServer handle on the StaPump, (2) MxAccessGalaxyBackend.OpenSession + Discover returns at least one gobject with attributes, (3) MxAccessGalaxyBackend.ReadValues against the first discovered attribute returns a response with the correct TagReference shape (value + quality vary by what's running, so we don't assert specific values). All 3 pass on this dev box. EndToEndIpcTests + IpcHandshakeIntegrationTests moved from Galaxy.Proxy.Tests (net10) to Galaxy.Host.Tests (net48 x86) — the previous test placement silently dropped them at xUnit discovery because Host became net48 x86 and net10 process can't load it. Rewritten to use Shared's FrameReader/FrameWriter directly instead of going through Proxy's GalaxyIpcClient (functionally equivalent — same wire protocol, framing primitives + dispatcher are the production code path verbatim). 7 IPC tests now run cleanly: Hello+heartbeat round-trip, wrong-secret rejection, OpenSession session-id assignment, Discover error-response surfacing, WriteValues per-tag bad status, Subscribe id assignment, Recycle grace window. Phase 2 exit-gate doc (docs/v2/implementation/exit-gate-phase-2.md) supersedes the partial-exit doc with the as-built state — Streams A/B/C complete; D/E gated only on the legacy-Host removal + parity-test rewrite cycle that fundamentally requires multi-day debug iteration; full adversarial-review section ranking 8 findings (2 high, 3 medium, 3 low) all explicitly deferred to Stream D/E or v2.1 with rationale; Stream-D removal checklist gives the next-session entry point with two policy options for the 494 v1 tests (rewrite-to-use-Proxy vs archive-and-write-smaller-v2-parity-suite). Cannot one-shot Stream D.1 in any single session because deleting OtOpcUa.Host requires the v1 IntegrationTests cycle to be retargeted first; that's the structural blocker, not "needs more code" — and the plan itself budgets 3-4 weeks for it.
