M3 Bundle F (Task F1) wires the cached-call audit pipeline through the
composition roots:
- Central: register SiteCallAuditActor as a cluster singleton + proxy
(mirrors AuditLogIngestActor and NotificationOutboxActor). Program.cs
calls .AddSiteCallAudit() on the central role.
- Site: register ICachedCallTelemetryForwarder + CachedCallLifecycleBridge
in AddAuditLog (lazy factory — Central nodes degrade to audit-only
emission because IOperationTrackingStore is site-only).
- Site: bind CachedCallLifecycleBridge to ICachedCallLifecycleObserver so
StoreAndForwardService picks it up via DI.
- Site: introduce IStoreAndForwardSiteContext + Host adapter to surface the
site id to StoreAndForwardService without creating a
StoreAndForward -> HealthMonitoring project-reference cycle.
- ScriptExecutionActor resolves ICachedCallTelemetryForwarder per script
scope and threads it into ScriptRuntimeContext.
CachedCallTelemetryForwarder's IOperationTrackingStore dependency is now
nullable so Central DI validation succeeds with the lazy registration; the
forwarder's tracking-half emission is a no-op when the store is absent.
Tests:
- AkkaHostedServiceAuditWiringTests: Central host builds with
AddSiteCallAudit and resolves ICachedCallTelemetryForwarder; Site
resolves the forwarder + bridge + observer + IStoreAndForwardSiteContext.
- Full solution: 194 Host tests green, 241 SiteRuntime tests green, every
other suite unchanged.
Wires Bundle E of the M2 site-sync pipeline:
- AddAuditLog extended to register the site writer chain (SqliteAuditWriter
singleton + ISiteAuditQueue forward + RingBufferFallback + FallbackAuditWriter
composing them) and the telemetry collaborators (SiteAuditTelemetryOptions,
SqliteAuditWriterOptions, IAuditWriteFailureCounter NoOp default,
ISiteStreamAuditClient NoOp default).
- AkkaHostedService central role: AuditLogIngestActor as ClusterSingletonManager
(singleton name 'audit-log-ingest') + ClusterSingletonProxy, mirroring the
Notification Outbox pattern. Proxy is offered to SiteStreamGrpcServer if it
resolves (Site path only today; M6 reconciliation will host gRPC on central).
- AkkaHostedService site role: SiteAuditTelemetryActor (per-site, NOT a
singleton because each site is its own cluster), bound to a dedicated
audit-telemetry-dispatcher (ForkJoinDispatcher, 2 dedicated threads).
- Program.cs + SiteServiceRegistration.Configure call AddAuditLog on both roles.
- AuditLogIngestActor gains a second constructor that takes IServiceProvider so
the cluster singleton can create a fresh scope per message — IAuditLogRepository
is a scoped EF Core service and cannot be pre-resolved from the root. The
IAuditLogRepository constructor remains for Bundle D's MSSQL-fixture tests.
NoOp ISiteStreamAuditClient is deliberate: no site→central gRPC channel exists
in M2 (sites talk to central via Akka ClusterClient; gRPC SiteStreamService is
hosted on sites for central→site streaming). M6 reconciliation introduces the
real gRPC site→central client + central-hosted gRPC server. Bundle H's
integration test substitutes a stub client directly via the actor's Props.
Tests:
- tests/ScadaLink.AuditLog.Tests/AddAuditLogTests.cs — 11 tests (was 3): writer
singleton, IAuditWriter as FallbackAuditWriter, ISiteAuditQueue same-instance
as SqliteAuditWriter, options bind round-trip, NoOp default assertions.
- tests/ScadaLink.Host.Tests/AkkaHostedServiceAuditWiringTests.cs (new) — 13
tests: BuildHocon emits audit-telemetry-dispatcher block with the expected
type/throughput/thread-count; Central composition root resolves the writer
chain + options; Site composition root resolves the writer chain + options +
NoOp client.
Verified: dotnet build clean, 23 test suites green (Host 194 + AuditLog 54).
Wire the Notification Outbox into the Host central role:
- Program.cs: call AddNotificationOutbox() on the central path (binds
NotificationOutboxOptions via BindConfiguration; no explicit Configure).
- AkkaHostedService.RegisterCentralActors(): create the NotificationOutboxActor
as a non-role-scoped central cluster singleton + proxy, then send
RegisterNotificationOutbox(proxy) to the CentralCommunicationActor.
- appsettings.Central.json: add the ScadaLink:NotificationOutbox section with
the NotificationOutboxOptions defaults.
- SiteServiceRegistration: remove the now-dead AddNotificationService() call -
sites forward notifications to central rather than delivering over SMTP, and
no site component consumes the SMTP machinery.
- Host.csproj: add the ScadaLink.NotificationOutbox project reference.
- Tests: add central outbox singleton/proxy actor-path assertions, drop the
site OAuth2TokenService/INotificationDeliveryService resolution assertions,
and add NotificationOutbox to the component-library IConfiguration check.
Move all package versions into Directory.Packages.props so every project
resolves a single consistent version. Consolidates the Roslyn packages
(Microsoft.CodeAnalysis.CSharp.Scripting/Workspaces) onto 5.0.0, which
resolves the pre-existing NU1608 version-skew error in the test projects.
Restore inside the docker build was failing because TreatWarningsAsErrors
promotes NU1902/NU1903/NU1904 (vulnerable package warnings) to errors.
Bump the flagged packages to advisory-free versions:
- MailKit 4.15.1 -> 4.16.0 (GHSA-9j88-vvj5-vhgr)
- Microsoft.AspNetCore.DataProtection.EFCore 10.0.5 -> 10.0.7 (GHSA-9mv3-2cwr-p262, transitively pulls fixed System.Security.Cryptography.Xml — GHSA-37gx-xxp4-5rgx, GHSA-w3x6-4m5h-cxqf)
- OpenTelemetry.Api (transitive via Akka.Hosting) 1.9.0 -> 1.15.3 (GHSA-g94r-2vxg-569j, GHSA-8785-wc3w-h8q6) — added as a direct PackageReference in ScadaLink.Host to override the Akka.Hosting pin
To resolve the NU1605 downgrade chain triggered by DataProtection.EFCore
10.0.7 (which transitively requires Microsoft.EntityFrameworkCore >= 10.0.7
and friends), bump every Microsoft.* 10.0.5 reference across src/ and
tests/ to 10.0.7 in lockstep.
Switch site host to WebApplicationBuilder with Kestrel HTTP/2 gRPC server,
add GrpcPort/keepalive config, wire SiteStreamManager as ISiteStreamSubscriber,
expose gRPC ports in docker-compose, add site seed script, update all 10
requirement docs + CLAUDE.md + README.md for the new dual-transport architecture.

15 component AddXxx() extension methods, MapCentralUI/MapInboundAPI stubs
- WP-0.11: 12 per-component options classes with config binding
- WP-0.12: Sample appsettings for central and site topologies
- Add execution procedure and checklist template to generate_plans.md

57 tests pass, zero warnings.
17 source projects (Commons + Host + 15 components) and 17 xUnit test projects.
SLNX format, net10.0, nullable enabled, warnings as errors. All components
reference Commons; Host references all components. Builds and tests clean.
