FlowNode

Position

SubFlow

A sub-flow: a named, first-class execution unit grouping a contiguous set of member nodes. The executor treats it as a single composite unit with one entry and one exit (derived from the edges crossing its boundary) and can retry the whole unit on failure. Membership is by node id; the nodes themselves stay in the flat FlowGraph.nodes list.

Enums

EdgeOutcome

Conditional routing outcome on an outgoing edge.
