Derived templates store IsInherited placeholder rows mirroring inherited
members, but a base member added/changed/removed AFTER a child was derived
never reached the child — leaving the editor's editable tabs incomplete (#1)
and stored rows drifted from the resolved set (#2).
Fix (one order-independent reconcile, two entry points):
- Auto-propagation: every attribute/alarm/script add/update/delete now
reconciles the template's derived subtree (TemplateService.ReconcileDescendantsAsync),
hooked into all member-mutating paths incl. native-alarm-source CRUD in the
ManagementActor.
- Resync: ResyncInheritedMembersAsync repairs a template + its subtree on
demand — materialize missing placeholders, re-sync drifted ones, remove
orphans, across attributes/alarms/scripts/native sources. Exposed as
management ResyncInheritedMembersCommand (Designer-gated, audited) → CLI
`template resync-members` → a Resync button on the editor's staleness banner.
Reconcile drives off TemplateInheritanceResolver (same precedence + HiLo merge
as deploy), only ever touches IsInherited placeholders (never an authored
override), and matches the staleness comparison keys so the banner clears.
BuildDerivedTemplate now also materializes native-source placeholders at
compose time (previously omitted → any inherited native source was perpetually
stale).
Tests: +8 TemplateServiceTests (materialize / drift-update / orphan-remove /
override-untouched / base-cascade / multi-type / direct-propagate / end-to-end
add) + 1 ManagementService test fix (native-source add resolves TemplateService).
Affected suites green: TemplateEngine 446, ManagementService 230, CentralUI 866,
CLI 333, Transport 127, ConfigurationDatabase 307; full solution builds 0/0.

#3 — CollisionDetector counted a derived template's IsInherited placeholder
rows as a distinct origin from the parent members the inheritance walk
re-adds, reporting a spurious "Naming collision" for every inherited row and
blocking any attribute/composition add to a derived template. CollectDirectMembers
now skips IsInherited rows on the direct-template and inherited-parent walks;
it keeps them for the composed-module walk, where placeholders are the sole
representation of a derived module's inherited members (that walk does not
climb the composed template's parent chain).
#7 — SandboxAttributeAccessor (Central UI Test-Run host) omitted
WriteBatchAndWaitAsync / WaitAsync / WaitForAsync, so the editor false-flagged
valid instance scripts with CS1061 even though `template validate` and the
deploy gate accept them. Added the five overloads mirroring the runtime
AttributeAccessor; they throw a labelled ScriptSandboxException if run in
Test Run (the central sandbox has no device-batch / event-waiter transport).
Tests: +3 CollisionDetector unit + 1 end-to-end TemplateService (derived add
now succeeds); +2 ScriptAnalysisService diagnose-clean. Each new test verified
to fail without its fix with the exact user-facing symptom. Full suites green
(TemplateEngine.Tests 438, CentralUI.Tests 866).

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).
Design: docs/plans/2026-05-18-contained-template-names-design.md
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.
