Deleting an instance only undeployed it from the site and set the state
to NotDeployed, leaving an orphan record that could never be removed —
the state-transition matrix rejected delete from NotDeployed.
Delete now removes the instance record entirely (deployment history,
snapshot, attribute/alarm overrides, and connection bindings go with
it), and is permitted from any state.
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.
NotificationRepository.GetAllNotificationListsAsync() was missing
.Include(Recipients), causing artifact deployments to push empty recipient
lists to sites. Also load shared scripts from SQLite on DeploymentManager
startup so they're available before Instance Actors compile their scripts.
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.
