26 TDD tasks across six phases — data layer, message contracts, the new
ScadaLink.NotificationOutbox project (actor, dispatcher, Email adapter),
site S&F retarget and central wiring, Central UI, and verification.
11 bite-sized documentation tasks covering the new component doc and
revisions across the affected component docs, README, and CLAUDE.md,
with a final cross-reference consistency sweep.
Resolves the six open questions: host-level forward-retry config,
Notify.Status returns a status record, 10-min stuck threshold, a
site-local Forwarding state, site-side logging of forward failures
only, and point-in-time KPIs computed from the Notifications table.
Captures the basic design for a reliable notification outbox: sites
store-and-forward notifications to the central cluster, which logs
them to a type-agnostic Notifications table (single audit source) and
delivers them via per-type adapters with retry, parking, and KPIs.
The Template Properties card repeated the parent template, which the page
header already shows — the "inherits X" line for base templates and the
"Derived from X — composed inside Y" line for derived ones. The card now
carries only Name and Description.
A composition-derived template now stores its contained name — the
composition slot's InstanceName (e.g. "Pump"), unique only within its
owner — instead of the dotted global path ("Motor Controller.Pump").
The qualified hierarchical name is computed on read.
- TemplateNaming.QualifiedName: walks the OwnerCompositionId chain to
build the dotted path; null-safe, cycle-guarded.
- TemplateConfiguration: the unique index on Template.Name becomes
filtered (WHERE IsDerived = 0) — base templates stay globally unique;
derived templates' uniqueness is the existing (TemplateId,
InstanceName) index on TemplateComposition.
- Migration ContainedDerivedTemplateNames: rewrites derived rows to the
contained name; Down rebuilds the dotted names via a recursive CTE
before restoring the global index.
- TemplateService: composition create/rename store the contained name;
the dotted-name collision pre-checks and cascade-rename are removed
(a slot rename no longer touches nested derived templates).
- TemplateEdit: title shows the contained name; the qualified path is a
breadcrumb subtitle; "composed inside" uses the owner's qualified name.
TDD: 4 TemplateNaming tests + updated composition tests. TemplateEngine
293, ConfigurationDatabase 114, CentralUI 316 green. Migration applied to
the dev cluster and verified in the browser (Motor Controller.Pump now
titled "Pump"; nested Motor Controller.Pump.TempSensor resolves).

Script editor modal (TemplateEdit): the tabbed Trigger/Code/Parameters/
Return content is substantial, so the dialog now fills most of the
viewport — a .script-editor-modal class (96vw wide, ~full height) replaces
modal-xl, paired with modal-dialog-scrollable so the body scrolls.
Shared Script create/edit form (SharedScriptForm): Code, Parameters, and
Return type move from stacked sections into a tab strip, matching the
template script modal. Panels toggle via display:none so the Monaco editor
and JSONJoy island stay mounted across tab switches; Code is the default
tab. Name stays above the tabs.
Markup/CSS only — no logic change. CentralUI suite 316 green; both
verified in the browser.
The Add/Edit Script modal's Trigger configuration (trigger editor + Min
time between runs) moves out of the always-visible header area and into
the tab strip as a new first tab: Trigger | Code | Parameters | Return
type. Trigger is the default selected tab.
Name and Locked remain above the tabs. The Trigger panel toggles via
display:none like the others, so the trigger expression's Monaco editor
stays mounted across tab switches. Markup-only — no logic change; verified
in the browser. CentralUI suite 316 green.
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.
InstanceActor._tagPathToAttribute was a Dictionary<string,string> — one tag
path mapped to a single attribute. When two attributes reference the same PLC
node (e.g. two composed cooling-tank modules both reading ns=3;s=Tank.Level,
or a pump's TempSensor and AlarmSensor both reading ns=3;s=Sensor.Reading),
SubscribeToDcl's map assignment overwrote, so only the last-registered
attribute ever received values — the rest stayed permanently Uncertain.
The map is now Dictionary<string,List<string>>; HandleTagValueUpdate fans each
update out to every attribute referencing the tag path, and each distinct tag
path is still subscribed only once per connection.
