The largest themed batch — small mechanical fixes across 11 modules.
API / message hygiene:
- Comm-020: SiteAddressCacheLoaded now carries IReadOnlyDictionary /
IReadOnlyList — Akka messages must be immutable.
- Commons-016: BundleSession.MaxUnlockAttempts named constant replaces
magic 3.
- Commons-018: IOperationTrackingStore + IPartitionMaintenance moved from
Interfaces/ root to Interfaces/Services/ (namespace preserved — 9
consumers exceeded the in-prompt move threshold).
- Commons-023: TrackingStatusSnapshot.SourceNode now consistent with the
trailing-optional-with-default pattern used elsewhere.
- SR-022: AuditingDbCommand.DbConnection.set no longer uses reflection —
exposes AuditingDbConnection.Inner via internal API surface.
Dead code / config cleanup:
- ClusterInfra-011: decorative SectionName constant deleted.
- ClusterInfra-014: dead AddClusterInfrastructureActors method + its
"throws-when-called" test deleted.
- Host-021: Microsoft Logging:LogLevel block deleted from appsettings.json
(dead under Serilog).
Fail-loud over fail-silent:
- DM-021: ResolveSiteIdentifierAsync throws on missing site (was silently
substituting a DB id).
- DM-022: dropped transient Pending write — record now lands directly in
InProgress (no UI flicker, one fewer DB write).
- Host-020: LoggerConfigurationFactory emits a Console.Error warning when
both Serilog:MinimumLevel and ScadaLink:Logging:MinimumLevel are set
(ScadaLink remains truth per Host-011).
- SnF-022: NotifyCachedCallObserverAsync logs Warning on unparseable
TrackedOperationId (was silently dropping).
- SnF-023: empty siteId default replaced with $unknown-site sentinel
+ constructor normalisation.
Correctness:
- SCA-001: SupervisorStrategy XML rewritten to match actual
DefaultDecider/Restart semantics (was claiming Resume).
- SCA-003: OnUpsertAsync now restamps IngestedAtUtc on every upsert.
- SR-021: HandleDeployArtifacts now dispatches an internal
ApplyArtifactDataConnectionsToDcl message after the SQLite write so
system-wide artifact-deploy data-connection changes go live
immediately (was requiring a site restart).
- SnF-020: RetryParkedMessageAsync captures the parked row BEFORE the
local write so a concurrent delete can't skip standby replication.
Sentinels / naming collisions:
- HM-021: CentralSiteId changed from "central" to "$central"
(uncollideable — leading $ is forbidden in real SiteIdentifiers).
Doc / surface cleanups:
- SEL-018: FailedWriteCount promoted to ISiteEventLogger; XML softened
to "Available for future Health Monitoring integration".
- SnF-019: VERIFY outcome — documented parking-after-DefaultMaxRetries
in Component-StoreAndForward.md + DefaultMaxRetries XML (uniform
cap; maxRetries:0 is the unbounded escape hatch).
- SnF-021: Component-StoreAndForward.md no longer claims the tracking
table lives in SnF — it's in SiteRuntime, the interface is in Commons.
- CLI-020: bundle export response parse guarded with try/catch on
JsonException / KeyNotFoundException / FormatException — emits a
clean INVALID_RESPONSE exit instead of a stack trace.
Config:
- ClusterInfra-013: intent comment added to "catastrophic config" test.
- Host-016: appsettings.Site.json second CentralContactPoints entry
removed (was pointing at the SITE's own port); doc-key explains how
to extend.
- Host-018: NodeName added to both shipped per-role configs (was
causing SourceNode to be null on audit rows).
UI:
- CentralUI-029: replaced JS.InvokeAsync<int>("eval", …) with an ES
module import (new wwwroot/js/browser-time.js).
- CentralUI-032: AuditResultsGrid gains a Previous button backed by a
cursor stack.
10+ new regression tests across the affected projects. Build clean;
all suites green. README regenerated: 6 open (was 33).
Session-to-date: 130 of 136 originally-open Theme findings closed.
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.
- Add JoeAppEngine folder to OPC UA nodes.json (BTCS, AlarmCntsBySeverity, Scheduler/ScanTime)
- Fix DataConnectionActor: capture Self in PreStart for use from non-actor threads,
preventing Self.Tell failure in Disconnected event handler
- Implement InstanceActor.HandleConnectionQualityChanged to mark attributes Bad on disconnect
- Fix LmxFakeProxy TagMapper to serialize arrays as JSON instead of "System.Int32[]"
- Allow DataType and DataSourceReference updates in TemplateService.UpdateAttributeAsync
- Update test_infra_opcua.md with JoeAppEngine documentation
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.
