- FBSubFlowNode/FBSubFlowBehavior run a referenced FBFlow synchronously and route on #success/#error via FBTransition>>resultName
- FBScope wired: one child scope per sub-flow call, depth-tracked via parentId chain, configurable per-node maxDepth (FBSubFlowMaxDepthExceeded guards against unbounded recursion)
- FBFlowInstance>>subFlowInstances tracks parent->child sub flow instances (one-directional, no back-reference)
- FBSubFlowInvalidTarget signalled when wiring a sub flow with != 1 end node
