The last two whole-library template reads are gone. Both fed the
inheritance-only TemplateInheritanceResolver, which walks one template's
parent chain and never follows compositions.
- TemplateService.ResyncInheritedMembersAsync (operator repair, CLI + editor)
now reads #86's GetTemplateReconcileClosureAsync (derived subtree + the
template's chain, tracked). When nothing derives from the template the
closure is empty, so it falls back to the new tracked
GetTemplateChainAsync - resyncing a leaf reads only its own chain.
- ManagementActor.HandleGetResolvedTemplateMembers now reads
GetTemplateChainAsync(id, trackChanges: false): the chain alone, untracked,
with script bodies (the resolver projects script code, so #66's body-free
analysis closure would not be equivalent).
The chain walk is factored out of TemplateReconcileClosure into
CollectChainAsync (one load per level, stops on parent cycles and dangling
parents) and shared by both.
Evidence:
- TemplateChainReadTests (#86 fixture): for every template plus an unknown
id, the closure-backed resync issues exactly the writes, audit row and
result of the whole-graph resync with GetAllTemplatesAsync wired to throw;
the resolver answers identically from the chain and the whole graph.
17 of these fail against the old service; 13 fail with the leaf chain
fallback removed (mutation-checked).
- TemplateChainRepositoryTests (SQLite, recorded SQL): a 4-deep chain loads
4 templates / 8 attributes instead of 46 / 92, one split-query set per
level, untracked on request and tracked for the resync.
- ResolvedTemplateMembersReadTests: the actor answers from the untracked
chain read and never calls GetAllTemplatesAsync (fails on the old actor).

TemplateService.ReconcileDescendantsAsync - run after every base member
add/update/delete, template and native-alarm-source alike - loaded the whole
tracked template graph (every template, member and script body) on each call,
which after #66 was the dominant cost of those paths. It now calls the new
ITemplateEngineRepository.GetTemplateReconcileClosureAsync: the same tracked,
fully-included shape as GetAllTemplatesAsync, restricted to the edited
template's derived subtree plus its own inheritance chain. The reconcile is
inheritance-only (TemplateInheritanceResolver never follows compositions) and
every descendant's chain runs through the edited template, so that set is
everything it reads.
The walk (Commons TemplateReconcileClosure, the descendant-direction twin of
#66's TemplateAnalysisClosure) loads one children batch per subtree depth and
one batch per ancestor level, terminates on parent cycles and stops at
dangling parents. A template with no children - the common case - costs one
empty probe and loads nothing.
Evidence:
- TemplateReconcileClosureTests: for every template of a graph with a deep
subtree, an ancestor above the edited template, a composed module,
look-alike unrelated trees, a parent cycle and a dangling parent, the
closure-backed reconcile issues exactly the writes (add/update/delete,
audit, save) of the old whole-graph reconcile, and the resolver answers
identically for every descendant. Fails with the old service (whole-graph
load wired to throw) and with the ancestor walk removed (mutation-checked).
- TemplateReconcileClosureRepositoryTests (SQLite, recorded SQL): 5 templates
/ 10 attributes instead of 47 / 94, tracked with script bodies; a leaf costs
one probe query and tracks nothing.
- TemplateServiceTests: attribute add + update propagate two levels down with
GetAllTemplatesAsync wired to throw; existing propagation tests now run
against the closure via ServeReconcileClosureFromFullGraph.
ResyncInheritedMembersAsync (operator action) still reads the whole graph.
