Pure Roslyn syntax walk (SourceCodeKind.Script, no semantic model, DB-free) that turns a
method or site script into PredictedNode/PredictedEdge chains in source order: Route.To(x)
.Call/SetAttributes/WaitForAttribute, Scripts.Call, Attributes.WriteBatchAndWaitAsync/
WaitAsync/WaitForAsync/SetAsync, Attributes[x] = v, ExternalSystem/Database/Notify. String
literals resolve; anything else is InputDependent with the expression text as title. An
if-return guard becomes a note on the node that follows it (condition visited first, so a
guard whose condition IS the traced call — Delmia's WriteBatchAndWaitAsync — attributes
correctly). Routed/nested script bodies come from a caller-supplied resolver, recursion
capped by maxDepth; parse errors and any walker fault degrade to request+response with a
'parse error' note. Predicted kinds are exactly the traced kinds so the page can overlay by
kind + title. Deviation from the plan's node count: no separate central 'method script'
node — the real graph records none, so the InboundRequest node stands for it.
