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.
