Interface: FlowNode<TIn, THandle, TStepIds>

Defined in: ast/flow-node.ts:17

Passive AST node representing a declarative multi-step workflow (P.flow(id)).

Binds an input schema, a capability-tiered IsolationScopeASTNode, an optional TelemetryCollectorASTNode, an ordered sequence of FlowStepNode and FlowBranchNode items, and a terminal exitState label.

Type Parameters

Type Parameter	Default type	Description
TIn	unknown	Validated flow input payload type.
THandle	unknown	Runtime handle type of the flow's isolation scope.
TStepIds extends string	string	Union of literal step and branch identifiers registered in nodes.
