Every value verified against Opc.Ua.StatusCodes in the pinned SDK (1.5.378.106) by
reflection, not by copying siblings. All are client-visible: OPC UA clients branch on
status.
The three named in #497:
- Historian.Gateway SampleMapper "BadNoData" 0x800E0000 -> 0x809B0000
(0x800E0000 is BadServerHalted)
- Galaxy "BadTimeout" 0x800B0000 -> 0x800A0000
(0x800B0000 is BadServiceUnsupported)
- TwinCAT BadTypeMismatch 0x80730000 -> 0x80740000
(0x80730000 is BadWriteNotSupported)
BadTypeMismatch was wrong in three MORE drivers the issue did not name — FOCAS,
AbLegacy and AbCip carried the same 0x80730000. Every call site is a
FormatException/InvalidCastException conversion failure, so the name was right and
the value was wrong in all four.
Adding the reflection guard then surfaced nine further defects offline tests had
never checked:
- Galaxy GoodLocalOverride 0x00D80000 -> 0x00960000 (not a UA code at all)
- Galaxy UncertainLastUsableValue 0x40A40000 -> 0x40900000
- Galaxy UncertainSensorNotAccurate 0x408D0000 -> 0x40930000
- Galaxy UncertainEngineeringUnitsExceeded 0x408E0000 -> 0x40940000
- Galaxy UncertainSubNormal 0x408F0000 -> 0x40950000
- TwinCAT BadOutOfService 0x80BE0000 -> 0x808D0000 (was BadProtocolVersionUnsupported)
- TwinCAT BadInvalidState 0x80350000 -> 0x80AF0000 (was BadAttributeIdInvalid)
- AbCip/AbLegacy GoodMoreData 0x00A70000 -> 0x00A60000 (was GoodCommunicationEvent)
- Historian.Gateway GatewayQualityMapper Good_LocalOverride 0x00D80000 -> 0x00960000
Galaxy's whole Uncertain block read as though the OPC DA quality byte could be
shifted into the UA substatus position; it cannot — the substatuses are an unrelated
enumeration. GatewayQualityMapper already held the correct table, which is what the
Galaxy values are now reconciled against.
Guard: StatusCodeParityTests (Core.Abstractions.Tests, which already project-
references every driver) reflects over every `const uint` in the deployed
ZB.MOM.WW.OtOpcUa.Driver.*.dll whose name reads as a status code, and asserts it
equals Opc.Ua.StatusCodes.<name>. Discovery is by convention, so a new driver
assembly referenced by that project is covered with no edit here. It went red on all
nine defects above before the fixes and now checks 109 constants green.
Because reflection can only see a NAMED constant, two inline literals were hoisted so
the guard can reach them: Galaxy's BadTimeout/Bad into StatusCodeMap, and
GatewayQualityMapper's 15-entry table into a new HistorianStatusCodes. An inline
`0x800B0000u, // BadTimeout` at a call site is exactly how the Galaxy defect survived.
The drivers stay SDK-free by design; only the test project references Opc.Ua.Core,
as the oracle.
Also corrected: tests that pinned the wrong values (Galaxy StatusCodeMapTests,
SampleMapperTests, GatewayQualityMapperTests — all written from the same bad source),
a mislabelled comment in DriverInstanceActorTests, and stale constants in two design
docs, one of them the unexecuted MTConnect driver design that would have propagated
BadNoData's wrong value into a new driver.
The CLI's SnapshotFormatter value->name table was checked against the SDK and is
correct; no change needed.
Imports the freshly-rebuilt ZB.MOM.WW.MxGateway.Client + ZB.MOM.WW.MxGateway.Contracts
nupkgs (0.1.0) from /tmp/mxgw-dist. Replaces the vendored libs/ DLLs and the
pre-restructure MxGateway.* namespaces across the runtime Galaxy driver,
Galaxy.Browser, and their tests.
Key changes:
- nuget-packages/ added as a local feed via NuGet.config; .gitignore exempts it
from the *.nupkg rule so the packages are tracked
- Directory.Packages.props pins both packages at 0.1.0
- 4 csprojs swap <Reference HintPath="libs/...dll"/> for <PackageReference/>
- 36 .cs files renamed `using MxGateway.*` -> `using ZB.MOM.WW.MxGateway.*`
- libs/ removed (vendored DLLs + README.md)
GalaxyBrowseSession rewritten around the new lazy API:
- RootAsync calls GalaxyRepositoryClient.BrowseAsync (returns LazyBrowseNodes)
and caches them by TagName instead of bulk-fetching the whole hierarchy
- ExpandAsync looks up the cached LazyBrowseNode and calls its ExpandAsync,
giving true one-wire-call-per-click instead of in-memory parent/child scan
- _byGobjectId + _hasChildrenSet dropped (LazyBrowseNode carries HasChildrenHint)
- AttributesAsync unchanged (already uses DiscoverHierarchyAsync MaxDepth=0)
Tests: Galaxy.Tests 245/245, Galaxy.Browser.Tests 10/10, AdminUI.Tests 66/66.
Pre-existing 12 solution errors unchanged (test sinks + Cli XML comments).
Adds <summary>, <param>, <typeparam>, and <inheritdoc/> tags to public
members surfaced by commentchecker — resolves 5,847 of 5,869 issues
(99.6%) across three /fixdocs passes.
StatusCode is not a .NET type reference in this assembly — replace the unresolvable
<see cref="StatusCode"/> with prose text so TreatWarningsAsErrors does not fail the
build on the CS1574 unresolved-cref warning.

Add StatusCodeMap.ToQualityCategoryByte(uint) so the StatusCode → quality-byte
mapping lives in one place next to its inverse (FromQualityByte). GalaxyDriver
OnPumpDataChange now delegates to the helper instead of duplicating the shift+switch
inline; a future edit to the OPC UA bit layout cannot silently desync the probe-health
decode. Unit tests in StatusCodeMapTests pin all three category buckets and the
round-trip invariant.

StatusCodeMap.FromMxStatus checked `success != 0` to determine success, but the
mxaccessgw proto contract explicitly documents that `success` is not a boolean and
that clients must branch on `category` (MX_STATUS_CATEGORY_OK), not on `success`
alone. Replace the raw field check with `status.IsSuccess()` from
MxStatusProxyExtensions, which requires both `success != 0` AND `category == Ok`.
A worker reporting success=1 with a non-OK category was previously misreported as
Good. Updated StatusCodeMapTests with a regression case covering the inverted scenario.

Group all 69 projects into category subfolders under src/ and tests/ so the
Rider Solution Explorer mirrors the module structure. Folders: Core, Server,
Drivers (with a nested Driver CLIs subfolder), Client, Tooling.
- Move every project folder on disk with git mv (history preserved as renames).
- Recompute relative paths in 57 .csproj files: cross-category ProjectReferences,
the lib/ HintPath+None refs in Driver.Historian.Wonderware, and the external
mxaccessgw refs in Driver.Galaxy and its test project.
- Rebuild ZB.MOM.WW.OtOpcUa.slnx with nested solution folders.
- Re-prefix project paths in functional scripts (e2e, compliance, smoke SQL,
integration, install).
Build green (0 errors); unit tests pass. Docs left for a separate pass.
