Attribute/alarm/script add (collision check) and update (parent-lock lookup)
used GetAllTemplatesForAnalysisAsync, materialising every template, attribute,
alarm and script in the library per edit. They now call the new
ITemplateEngineRepository.GetTemplateAnalysisClosureAsync: the same untracked,
body-free analysis projection, restricted to the template's inheritance chain
plus the composition closure of every chain member - exactly what
TemplateResolver and CollisionDetector walk (a composed module's own parent
chain is never climbed, so it is not loaded). Adds use the edited template's
closure, updates the parent's.
The walk (Commons TemplateAnalysisClosure) loads one batch per closure depth,
requests each id once, terminates on cycles and skips dangling edges.
Evidence:
- TemplateAnalysisClosureTests: for every template of a graph with chains,
nested + diamond compositions, a derived module, cycles, dangling edges and
colliding unrelated templates, ResolveAllMembers / DetectCollisions /
FindMemberByCanonicalName answer identically from the closure and the whole
graph (mutation-checked).
- TemplateAnalysisClosureRepositoryTests (SQLite, recorded SQL): 6 templates /
12 attributes loaded instead of 47 / 94, in 4 queries (one per depth),
untracked, script bodies never selected.
- TemplateServiceTests: two new tests with the whole-graph load wired to throw
(fail on the old service); every existing add/update test now runs against
the closure via AnalysisClosureMock.
ReconcileDescendantsAsync still loads the tracked full graph; not in scope.
