Function: matchesChild()
matchesChild(
child,runtimeNodeId):boolean
Defined in: packages/core/src/types.ts:399
Does this runtime NodeContext.nodeId belong to this structural child?
The one rule that joins structure to liveness, kept here next to the member
it reads so no consumer has to re-derive it. It is driven entirely by the
edge tag — no primitive is named — which is what keeps a dev panel, a
persistence layer, or anything else joining the two from growing a switch
over primitives that a new one would silently fall through.
A repeat child is one node in the structure and many executions at
runtime, so its nodeId is a stem and the runtime appends the ordinal.
Every other edge addresses its child exactly once.
The bare stem matches too, and has to: it is the child's structural
address — what getChildren() reports and what a consumer holds before any
run has happened. Matching only iteration-1, iteration-2, … meant a loop
body could be watched but never addressed, so an override aimed at it had
nowhere to land until the loop had already run.
