Function: executeCommand()

function executeCommand<TIn, TOut, THandle>(
   node, 
   input, 
   ctx
): Promise<TOut>;

Defined in: runtime/step/execute-command.ts:19

Executes a passive CommandNode (P.command(id)) by validating input, invoking node.fn(validatedInput, ctx), and validating the returned output (SPEC.md §2.3 & §3.7).

Enforces Declarative Compilation Invariant 6 (node is a passive AST record with zero .execute method; execution occurs exclusively here).

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.

Parameters

Parameter	Type	Description
node	CommandNode<TIn, TOut, THandle>	Passive CommandNode AST definition.
input	TIn	Raw or pre-mapped command input payload.
ctx	StepExecutionContext<THandle>	Active step execution context.

Returns

Promise<TOut>

Schema-validated command output payload.
