Remediates RESILIENCE-DISPATCH-GAP (surfaced by the 07/C-1 analyzer): the Phase 6.1
CapabilityInvoker resilience pipeline (retry / breaker / bulkhead / telemetry) was
constructed only in tests — the production dispatch layer called driver-capability
methods directly, bypassing it entirely.
The filed plan (thread CapabilityInvoker directly into DriverInstanceActor) is
INFEASIBLE: Runtime is deliberately Polly-free (references Core.Abstractions, not
Core — the same boundary IDriverFactory documents). So this introduces a seam,
mirroring IDriverFactory exactly:
- Core.Abstractions: IDriverCapabilityInvoker (+ NullDriverCapabilityInvoker
pass-through) and IDriverCapabilityInvokerFactory (+ null factory).
- Core: CapabilityInvoker now implements the interface; new
DriverCapabilityInvokerFactory builds a per-instance invoker over the
process-singleton pipeline builder + status tracker + tier resolver.
- Runtime: DriverInstanceActor takes an IDriverCapabilityInvoker (default =
pass-through) and routes all 6 dispatch sites (write, alarm-ack, subscribe,
unsubscribe, alarm-subscribe, discover) through it; per-host key resolved via
IPerCallHostResolver for single-ref calls, driver-instance key for bulk calls.
DriverHostActor builds + injects the real invoker per spawned driver.
- Host: DriverFactoryBootstrap registers the tracker, pipeline builder, and
concrete factory (needs DriverFactoryRegistry.GetTier). Runtime SCE resolves the
factory from DI like IDriverFactory; pass-through on nodes without it bound.
- Analyzer: IDriverCapabilityInvoker.ExecuteAsync/ExecuteWriteAsync are now
recognized wrapper homes (interface-typed invoker calls must suppress OTOPCUA0001
too). All 6 RESILIENCE-DISPATCH-GAP pragmas removed — the analyzer (an error in
Runtime) is now the standing regression guard.
Also adds retry / breaker-open / breaker-close LOGGING to the pipeline builder —
the operator-facing observability surface (the Admin /hosts reader, Phase 6.1
Stream E.2/E.3, was never built, so the pipeline otherwise runs silently).
Scope notes:
- Tier-DEFAULT policy only: DriverInstanceSpec (the deploy artifact) does not carry
the per-instance ResilienceConfig JSON, so overrides aren't applied yet (tracked
follow-up: plumb ResilienceConfig through the composer/artifact).
- GenericDriverNodeManager's call is NOT wired: that class is test-only scaffolding
(zero production references — the Server has its own address-space path); its
pragma is re-annotated accordingly, not left as a "tracked gap".
Verification (unit + analyzer; live behavioral gate still pending — see FOLLOWUP-10):
- Negative control: unwrapping any site fails the Runtime build with OTOPCUA0001.
- New Runtime guard (recording invoker): write routes via ExecuteWriteAsync with the
IPerCallHostResolver host; subscribe via ExecuteAsync — proves runtime routing.
- New analyzer test: the interface is a valid wrapper home.
- New pipeline-builder test: retry events are logged.
- Full solution builds clean (0 errors); Runtime.Tests 357, Core.Tests 238,
Analyzers.Tests 32 all green; pass-through default keeps existing dispatch tests
byte-for-byte unchanged.
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.
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.
- Analyzers-002: drop the three dead AlarmSurfaceInvoker entries from
the wrapper-method allow-list and from the diagnostic message.
- Analyzers-003: bail out of AnalyzeInvocation when the semantic model
is null (was previously emitting a false positive).
- Analyzers-004: resolve guarded-interface + wrapper-method symbols
once via CompilationStartAction and compare with SymbolEqualityComparer
instead of formatting fully-qualified names on every invocation.
- Analyzers-005: add regression tests for default-interface-method
reads (ReadAtTimeAsync / ReadEventsAsync on a concrete driver), with
+ without an override, and inside a CapabilityInvoker.ExecuteAsync
lambda.
- Analyzers-007: rewrite the analyzer remarks to accurately describe
the symbol-identity guarded-call detection, DIM handling, and the
wrapper-lambda match heuristic.

Analyzers-001: IsInsideWrapperLambda now matches the wrapper method name
(ExecuteAsync/ExecuteWriteAsync) in addition to the containing type, so a
future non-callSite lambda overload cannot suppress the diagnostic.
Analyzers-006: extended StubSources and added coverage for the remaining
guarded interfaces, synchronous members, concrete-driver receivers,
ExecuteWriteAsync wrapping, and nested lambdas.

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.
