- IDriverProbe abstraction in Core.Abstractions; one impl per driver
type, resolved by DriverType string. Phase 7.3 + 7.4 add concrete
probes for the 9 supported driver types.
- TestDriverConnect / TestDriverConnectResult messages.
- AdminOperationsActor.HandleTestDriverConnectAsync looks up the probe
by DriverType, runs it with a [1,60]s clamped timeout, and returns
success/latency or failure/message. Probes that throw or time out
surface as soft failures.
- IDriverHealthPublisher in Core.Abstractions + NullDriverHealthPublisher
no-op for tests/dev-stub paths.
- AkkaDriverHealthPublisher in Runtime forwards to the cluster-wide
`driver-health` DPS topic.
- DriverInstanceActor instrumented to publish snapshots on every
observable state change + a periodic 30s heartbeat so the AdminUI
snapshot store warms up for newly-joined SignalR clients.
- Sliding 5-minute Faulted-count tracked per actor via Queue<DateTime>.
- DriverHostActor.SpawnChild threads clusterId (_localNode.Value) and
the health publisher down to every DriverInstanceActor child.
- ServiceCollectionExtensions.AddOtOpcUaRuntime registers
AkkaDriverHealthPublisher as IDriverHealthPublisher singleton.
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.
DriverHostActor.ApplyAndAck now reads the deployment artifact and
reconciles its set of DriverInstanceActor children — spawn the missing,
ApplyDelta to those with changed config, stop the removed/disabled.
The diff lives in pure DriverSpawnPlanner so it can be unit-tested
without an ActorSystem.
Adds IDriverFactory in Core.Abstractions (consumed by Runtime) +
DriverFactoryRegistryAdapter in Core.Hosting that wraps the existing
v1 DriverFactoryRegistry — Runtime stays decoupled from Polly/Serilog,
the Host wires the adapter once driver assemblies have registered.
ShouldStub(type, roles) is now actually called on every spawn — Galaxy
+ Wonderware-Historian boot stubbed on macOS/Linux or whenever the host
carries the dev role. Missing factory ⇒ stub fallback, never a crash.
Tests: 24 → 34 in Runtime (+10):
- DriverSpawnPlannerTests x7 (diff cases, type change ⇒ stop+respawn)
- DeploymentArtifactTests x5 (empty/malformed/missing fields tolerant)
- DriverHostActorReconcileTests x4 (spawn count, stub fallback,
ShouldStub gate, second-apply stops the removed)
All 6 v2 test suites green: 120 tests passing.
Closes F20 (ShouldStub wired). F7 marked partial — subscription
publishing + write path still stubbed in DriverInstanceActor itself.
Phase 1c of the v2 entity-model rewrite. Deletes the draft/publish lifecycle
machinery that v2 replaces with AdminOperationsActor + ConfigComposer +
DriverInstanceActor.ApplyDelta.
Deleted (6 files):
src/Core/ZB.MOM.WW.OtOpcUa.Configuration/Apply/
IGenerationApplier.cs — interface for the apply pipeline
GenerationApplier.cs — the v1 applier coordinating per-driver hook-back
GenerationDiff.cs — typed wrapper over the sp_ComputeGenerationDiff
SQL output
ApplyCallbacks.cs — per-driver hook surface invoked by the applier
ChangeKind.cs — enum {Added, Modified, Removed, Unchanged}
tests/Core/ZB.MOM.WW.OtOpcUa.Configuration.Tests/GenerationApplierTests.cs
The empty Apply/ directory is removed.
Kept (repurposed in Task 39 for stale-config fallback):
src/Core/ZB.MOM.WW.OtOpcUa.Configuration/LocalCache/GenerationSealedCache.cs
src/Core/ZB.MOM.WW.OtOpcUa.Configuration/LocalCache/ResilientConfigReader.cs
tests/Core/ZB.MOM.WW.OtOpcUa.Configuration.Tests/GenerationSealedCacheTests.cs
tests/Core/ZB.MOM.WW.OtOpcUa.Configuration.Tests/ResilientConfigReaderTests.cs
Naming rename (GenerationSealedCache -> DeploymentArtifactCache) deferred
to Task 39 (DriverHostActor stale-config fallback) where the consumer is
written. The type stays available under its v1 name until then.
IDriver.cs doc-comment: replaced the "Used by IGenerationApplier..." sentence
with "Invoked by the v2 DriverInstanceActor when ApplyDelta reports that only
this driver's config changed in the new deployment."
Server/Admin breakage from Task 14b unchanged (70 errors). Configuration +
Core.Tests + Configuration.Tests stay green.
src/Core/ZB.MOM.WW.OtOpcUa.Configuration -> 0 errors
tests/Core/ZB.MOM.WW.OtOpcUa.Configuration.Tests -> 0 errors
whole solution -> 70 errors (all in Server/Admin)
- Core.Abstractions-004: guard DriverTypeRegistry.Register with a Lock so
concurrent registrations are atomic.
- Core.Abstractions-005: narrow PollGroupEngine catch blocks to non-fatal
exceptions, add optional onError callback, tolerate disposed-CTS races.
- Core.Abstractions-006: document the deliberate int-vs-uint asymmetry on
IHistoryProvider.ReadEventsAsync / IHistorianDataSource.ReadEventsAsync.
- Core.Abstractions-007: pin the gaps with PollGroupEngine + DriverHealth
contract tests.
- Core.Abstractions-008: correct XML docs on DriverHealth.LastError and
the optional / required asymmetry on the history-read surfaces.

Core.Abstractions-001: PollGroupEngine compares array values with structural
equality so a driver returning a fresh T[] each poll no longer fires spuriously.
Core.Abstractions-002: PollOnceAsync guards reader result cardinality and
throws a descriptive InvalidOperationException on mismatch instead of a
swallowed ArgumentOutOfRangeException that stalled the subscription.
Core.Abstractions-003: the poll loop Task is tracked; Unsubscribe/DisposeAsync
await loop completion before disposing the CTS.

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.
