New TemplateChildEquality is the one place "has this template child changed?" is
decided, comparing the COMPLETE writable field set per entity (attributes now incl.
ElementDataType + LockedInDerived; alarms incl. the on-trigger script by name +
LockedInDerived; scripts incl. MinTimeBetweenRuns/ExecutionTimeoutSeconds +
LockedInDerived; native sources per T5). ArtifactDiff.CompareTemplate and all four
BundleImporter.SyncTemplate*Async predicates now route through it — closing the
class of bug where Preview reported Identical for an artifact an Overwrite would
mutate. The attribute sync passes a value-normalised DTO so List-value re-imports
stay idempotent; the alarm on-trigger change now surfaces in both diff and sync.

New TemplateNativeAlarmSourceDto + init-only TemplateDto.NativeAlarmSources (empty
default, additive — IsInherited placeholders carried for the collision detector).
Exported in ToBundleContent, consumed in FromBundleContent + BuildTemplate, and a
new SyncTemplateNativeAlarmSourcesAsync runs the Overwrite add/update/delete child
sync with per-change audit rows. ArtifactDiff.CompareTemplate now DiffChildren over
native sources so Preview reports a NativeAlarmSources field change. Proven by an
end-to-end flatten test: an instance native-alarm-source override that dangled
pre-fix now resolves against the re-imported template source.

Remove project bookkeeping citations from shipped code comments across the
solution: hyphenated task IDs (WP-14, StoreAndForward-025), milestone/task/
issue refs (M3, Task 4, Audit Log #23, #21), Bundle X task-bundle labels,
and C/D/K/S/T phase labels.
Comment text only — no code logic, string/log literals, or XML-doc structure
changed. Genuine descriptions are preserved (only the citation is stripped),
and technical lookalikes are retained (UTF-8, SHA-256, T00:00:00, M365,
UTC-5, pre-C4/pre-C5 schema versions). Flagged by the new CommentChecker
TaskReferenceInComment / TrackingReferenceInComment checks plus targeted
grep passes; full solution builds clean, append-only guard tests pass.
