Matrix-gate satisfied (14 passed / 1 skipped / 0 failed on 2026-04-30
per docs/v2/Galaxy.ParityMatrix.md). Galaxy access flows through the
in-process GalaxyDriver → mxaccessgw exclusively. Legacy infrastructure
deleted in this commit:
Source projects (6):
- src/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Host (.NET 4.8 x86 + MXAccess COM)
- src/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Proxy (in-process pipe client)
- src/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Shared (pipe-IPC contracts)
- tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Host.Tests
- tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Proxy.Tests
- tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Shared.Tests
Test projects with no consumer after legacy retired (3):
- tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.E2E (drove Galaxy.Host EXE)
- tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.ParityTests (drove both backends)
- tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.TestSupport (only consumed by Host/Proxy tests)
Edits:
- ZB.MOM.WW.OtOpcUa.slnx: drop nine project entries
- Server.csproj: drop Driver.Galaxy.Proxy ProjectReference
- Server/Program.cs: drop GalaxyProxyDriverFactoryExtensions.Register
+ the parallel-registration comment block; only GalaxyDriverFactoryExtensions
registers now under DriverType "GalaxyMxGateway"
- Install-Services.ps1: rewrite to drop OtOpcUaGalaxyHost service install +
the GalaxySharedSecret/ZbConnection/GalaxyClientName/GalaxyPipeName/
AvevaServiceDependencies/MxAccessInitialConnect* parameters that only
applied to the legacy host. Adds a closing note pointing operators at
the separate mxaccessgw install
- Uninstall-Services.ps1: keep OtOpcUaGalaxyHost in the cleanup loop so
pre-7.2 rigs upgrade-uninstall cleanly, plus add OtOpcUaWonderwareHistorian
- scripts/e2e/test-galaxy.ps1: deleted (drove the legacy E2E)
- scripts/e2e/e2e-config.sample.json: rewrite the galaxy section comment
to reflect the GalaxyMxGateway-only path
- scripts/e2e/README.md: drop OtOpcUaGalaxyHost references
- scripts/compliance/phase-7-compliance.ps1: drop Galaxy.Shared
HistorianAlarms* checks (those contracts moved to
Driver.Historian.Wonderware.Client in PR 3.4)
Live state: OtOpcUaGalaxyHost Windows service stopped + removed via
NSSM before this commit. The dev box's Galaxy access is now exclusively
through the running mxaccessgw (separate repo).
Stays out of scope for PR 7.2 (PR 7.3 territory):
- CLAUDE.md Galaxy section rewrite
- mxaccess_documentation.md deletion
- Memory entries for the now-retired Galaxy.Host service
