The template script editor had no input for MinTimeBetweenRuns, so a
WhileTrue trigger configured through the UI always saved a null interval
and degraded to a single edge fire. The Add/Edit Script modal now has a
"Min time between runs" number+unit (ms/sec/min) field.
- Visible only for ValueChange / Conditional / Expression triggers — the
auto-firing triggers MinTimeBetweenRuns throttles. Hidden for Interval
(its own period is the cadence), Call (invoked explicitly, never
throttled), and None.
- For a WhileTrue Conditional/Expression trigger the field is labelled as
the re-fire interval and shows a warning while it is blank.
- Wired through the new-script and edit-script save paths (edit previously
only preserved the existing value, never let the user change it).
New DurationInput helper does the TimeSpan <-> number+unit conversion;
ScriptTriggerConfigCodec.SupportsMinTimeBetweenRuns classifies trigger
types. Both TDD'd — 21 new tests. CentralUI suite 316 green; verified
end-to-end in the browser (visibility per trigger type, WhileTrue warning,
save/reload round-trip).
Conditional and Expression script triggers gain an optional `mode` field
in their TriggerConfiguration JSON:
- OnTrue (default): unchanged edge/per-change firing. An absent mode field
parses as OnTrue, so every existing trigger config behaves identically.
- WhileTrue: fires on the false->true edge, then re-fires on a periodic
timer while the condition holds; stops on the true->false edge. The
re-fire cadence is the script's MinTimeBetweenRuns; with none configured
the trigger degrades to a single edge fire and logs a warning.
ScriptActor tracks condition truth state and manages a dedicated
"whiletrue-trigger" timer. ScriptTriggerConfigCodec and ScriptTriggerEditor
round-trip the mode and expose an OnTrue/WhileTrue selector for the two
trigger kinds. Design: docs/plans/2026-05-18-whiletrue-trigger-mode-design.md
Tests: 7 ScriptActor runtime tests (edge fire, timer re-fire, stop,
re-arm, no-MinTimeBetweenRuns degrade, OnTrue regressions) + 14 codec /
editor tests. SiteRuntime suite 206 green, CentralUI suite 295 green.
DiffDialogTests.SetupBodyLockInterop registered bUnit SetupVoid planned
invocations that were never completed; DisposeAsync_WhileOpen awaited
DiffDialog.DisposeAsync -> TryUnlockBodyAsync -> InvokeVoidAsync on one of
them, suspending the test forever so the test host never exited (regression
from the CentralUI-023 catch-narrowing). SetupBodyLockInterop now uses Loose
JSInterop mode. Also dispose the leaked WebApplication instances in the Auth
tests (FileSystemWatcher + ConsoleLoggerProcessor threads) and the extra
ServiceProvider in the DebugView tests. Suite now runs 281 tests in ~7s and
exits cleanly.
A heartbeat-registered site that has never sent a full report now has
LastReportReceivedAt = null instead of the year-0001 sentinel. TimestampDisplay
accepts DateTimeOffset? and renders null as a placeholder ('awaiting first
report') rather than a ~2000-year-stale date. Cross-module: HealthMonitoring +
CentralUI.
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)
Replace raw-JSON text inputs with rich UI: script parameter/return types use
a JSON Schema builder (SchemaBuilder + JsonSchemaShapeParser, with a migration
to convert existing definitions); alarm trigger config uses a type-aware
editor with a flattened attribute picker (AlarmTriggerEditor). AlarmActor
gains optional direction (rising/falling/either) on RateOfChange triggers.
Editors now set a _normalized flag when ParseFromJson coalesces a
legacy type name (lowercase "string", "Int32", "Double", etc.) to the
canonical set. When flagged, render a small alert-info inline:
"Some parameter types were normalized... Save to persist the
canonical form." The flag clears on any user edit so the notice
doesn't linger after Emit overwrites the JSON.
31 new bUnit tests in tests/.../Shared/:
- ParameterListEditorTests: null/empty rendering, row count per
JSON entry, legacy type normalization across .NET names +
lowercase, the normalized notice trigger, add/remove emission,
List/non-List item-type column visibility, required-flag round
trip, invalid JSON + non-array error paths.
- ReturnTypeEditorTests: null vs simple vs List shape, legacy type
normalization, change-type / clear-type emission, invalid JSON
+ non-object error paths.
Total CentralUI test count: 82 -> 113.
