Interface: LaneNode<TIn, TStepIds>

Defined in: ast/lane-node.ts:108

Passive AST node representing a concurrent work execution lane (P.lane(id)).

Schedules deduplicated work items through flow under priority aging, prerequisite DAG barriers, USD budget ceilings, step retry policies, and live signal rewind handlers.

Type Parameters

Type Parameter	Default type	Description
TIn	unknown	Validated lane work item input type.
TStepIds extends string	string	Union of literal step and branch IDs in the bound FlowNode.
