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.
Add DriverTypeNames.Sql (+ All) as the shared source of truth, and wire the driver
into the Host: register the factory in DriverFactoryBootstrap.Register via
Driver.Sql.SqlDriverFactoryExtensions.Register(registry, loggerFactory), add the
SqlProbe (= Driver.Sql.SqlDriverProbe) probe via TryAddEnumerable, and add the
Driver.Sql project reference to the Host. Default tier A (SQL client is managed +
cross-platform, so ShouldStub needs no change).
Repoint the interim SqlDriver.DriverTypeName / SqlDriverFactoryExtensions.DriverTypeName
literals at DriverTypeNames.Sql; both still resolve to "Sql", so the AdminUI
TagConfigEditorMap/TagConfigValidator keys and the DriverTypeName-parity test stay
green. The Core guard test discovers factories from its own bin, so it also gains a
Driver.Sql project reference — that is the "registered-factory side" that lets
DriverTypeNamesGuardTests' bidirectional-parity check pass (4/4 green).

Adds the Calculation pseudo-driver (tags computed by C# scripts over other tags' live
values) plus the host seam that feeds it:
- IDependencyConsumer capability interface (Core.Abstractions) + DriverTypeNames.Calculation.
- CalculationDriver : IDriver, ISubscribable, IReadable, IDependencyConsumer — change-gate +
dedupe (VirtualTagActor parity), timer-group scheduler, Bad-transition + script-log emission,
Good recovery; reuses the T0-4 CalculationEvaluator.
- DriverHostActor spawns a DependencyConsumerMuxAdapter per dependency-consuming driver,
registering its refs on the per-node DependencyMuxActor and forwarding DependencyValueChanged
→ OnDependencyValue; re-registers on every apply, torn down with the driver.
- Factory + probe registered in DriverFactoryBootstrap (keeps the T0-3 guard green); guard test
csproj references the driver so the bin-scan discovers the factory.
- DeploymentArtifact injects the resolved scriptSource (scriptId → SourceCode) into a calc tag's
delivered TagConfig so the host-blind driver can compile it.
- DraftValidator deploy gates: CalculationScriptMissing / CalculationScriptNotFound (scriptId
existence) + CalculationDependencyCycle (DependencyGraph.DetectCycles over calc→calc edges).
- Tests: driver units (dep-ref extraction, change-gate, dedupe, Bad+script-log+recovery, timer,
read), tag-config parsing, DraftValidator gates (self/2-cycle/cross-driver-terminal), and a
Runtime integration test proving values FLOW mux → adapter → driver → calc-of-calc end-to-end.

Add DriverTypeNames as the single source of truth for driver-type
dispatch strings, one const per currently-registered driver factory
(value = the exact factory DriverTypeName). Fixes the latent drift
between hand-authored dispatch-map literals and the real factory names
(e.g. TwinCAT/FOCAS/GalaxyMxGateway) at the source.
A reflection guard test in Core.Abstractions.Tests builds the real
registered-factory set by driving each *DriverFactoryExtensions.Register
into a live DriverFactoryRegistry (mirroring the Host's
DriverFactoryBootstrap) and asserts bidirectional parity with the
constants, so any future rename on either side breaks the test gate.
Consumers are rewired in Batch 2 WP8; Calculation's const lands with its
factory in WP7.

Adds Directory.Packages.props (ManagePackageVersionsCentrally) and
Directory.Build.props (net10.0/nullable/implicit usings/LangVersion latest).
Strips Version attributes from every csproj PackageReference and consolidates
versions into the central file.
Side fixes (necessary to keep the build green on .NET SDK 10.0.105 on macOS):
- Microsoft.CodeAnalysis.CSharp{,.Workspaces}: 5.3.0 -> 5.0.0. The 5.3.0
analyzer DLL references compiler 5.3.0.0 and the local SDK ships compiler
5.0.0.0, producing CS9057 on every project that loaded the Analyzers
output. Master itself was broken on this machine pre-change.
- Server + Server.Tests pin OPCFoundation.NetStandard.Opc.Ua.{Configuration,
Client} to 1.5.374.126 via VersionOverride, matching Opc.Ua.Server's
pin. Mixing 1.5.378.106 Opc.Ua.Core transitively with 1.5.374.126
Opc.Ua.Server breaks CustomNodeManager2 override signatures
(CS0115 on LoadPredefinedNodes/Browse/HistoryRead*) and CS7069 in
the tests. The pin disappears when the legacy Server project is
deleted in Task 56.
- Client.UI + Client.UI.Tests: NuGetAuditSuppress for
GHSA-xrw6-gwf8-vvr9 (Tmds.DBus.Protocol 0.20.0 reaches both projects
transitively from Avalonia.Desktop on Linux/macOS only).
Deviation from the plan: TreatWarningsAsErrors=true is NOT set in
Directory.Build.props because the pre-v2 Admin/Server test projects carry
~240 xUnit1051 analyzer warnings that would fail the build. New v2 projects
opt in via their own csproj; the global flag can return once the legacy
projects are deleted in Task 56.
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.
