Adds a new HiLo alarm trigger type with four configurable setpoints
(LoLo / Lo / Hi / HiHi). Each setpoint carries an optional priority,
deadband (for hysteresis), and operator message. The site runtime emits
AlarmStateChanged with an AlarmLevel field so consumers can differentiate
warning vs critical bands.
Plumbing:
- new AlarmLevel enum + AlarmStateChanged.Level/Message init properties
- AlarmTriggerEditor (Blazor) gets a HiLo render with severity tinting
- AlarmTriggerConfigCodec extracted from the editor for testability
- sitestream.proto carries level + message over gRPC
- SemanticValidator enforces numeric attribute, setpoint ordering,
non-negative deadband
- on-trigger scripts get an Alarm global (Name/Level/Priority/Message)
so notification routing can branch by severity
- per-instance InstanceAlarmOverride entity + EF migration + flattening
step + CLI commands; HiLo overrides merge setpoint-by-setpoint, binary
types whole-replace
- DebugView shows a Level badge + per-band message tooltip
- App.razor auto-reloads on permanent Blazor circuit failure
- docker/regen-proto.sh automates the proto regen workflow (the linux/arm64
protoc segfault means generated files are checked in for now)
Two caveats from the script-scope rollout addressed:
1. ITemplateEngineRepository.GetTemplatesComposingAsync — a scoped
query that returns only the templates referencing a given template
via Compositions, eager-loaded with their Attributes / Scripts /
Compositions. Replaces the GetAllTemplatesAsync + filter pattern
in TemplateEdit so the Monaco metadata fetch doesn't pull the
entire template catalog to find one parent.
2. Multi-parent picker. The previous implementation suppressed Parent
assistance entirely when more than one template composes the open
one. Now TemplateEdit collects every parent into _editorParents
and renders a small `select` above the script editor when there
are >1, letting the user choose which parent's metadata drives
Parent.Attributes / Parent.CallScript completion + diagnostics.
Single-parent templates skip the picker (no UI change). Zero
parents (root template) hide the picker and surface no Parent
assistance.
Browser-verified on the Sensor Module template (composed by both Pump
and Variable Speed Motor): picker shows both options, switching
updates the editor's parent metadata immediately via the existing
GetContext callback.
Test counts unchanged (159 / 199); the new repo method is exercised
end-to-end by the parent-picker browser path.
Replace SiteDataConnectionAssignment join table with a direct SiteId FK on DataConnection,
simplifying the data model, repositories, UI, CLI, and deployment service.
- 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
Add SiteReplicationActor (runs on every site node) to replicate deployed
configs and store-and-forward buffer operations to the standby peer via
cluster member discovery and fire-and-forget Tell. Wire ReplicationService
handler and pass replication actor to DeploymentManagerActor singleton.
Fix 5 pre-existing ConfigurationDatabase test failures: RowVersion NOT NULL
on SQLite, stale migration name assertion, and seed data count mismatch.
Bootstrap served locally with absolute paths and <base href="/">.
LDAP auth uses search-then-bind with service account for GLAuth compatibility.
CookieAuthenticationStateProvider reads HttpContext.User instead of parsing JWT.
Login/logout forms opt out of Blazor enhanced nav (data-enhance="false").
Nav links use absolute paths; seed data includes Design/Deployment group mappings.
DataConnections page loads all connections (not just site-assigned).
Site appsettings configured for Test Plant A; Site registers with Central on startup.
DeploymentService resolves string site identifier for Akka routing.
Instances page gains Create Instance form.
