Interface: CommandNode<TIn, TOut, THandle>

Defined in: ast/command-node.ts:15

Passive AST node representing a deterministic TypeScript step command (P.command(id)).

Carries input/output Zod validation schemas, an optional partition extractor, and a passive callback fn invoked exclusively by the runtime's executeCommand NodeExecutor (zero .execute method on the node).

Type Parameters

Type Parameter	Default type	Description
TIn	unknown	Validated command input payload type.
TOut	unknown	Validated command output payload type.
THandle	unknown	Runtime handle type of the active isolation scope.
