For Loop (forLoopNode)

Category: Control Flow

Intended behavior

Fires the Body trigger Count times (index output counts up), then fires Done.

Inputs

ID	Label	Type	Unwired default
inTrigger	Run	trigger	undefined
count	Count	number	3

Outputs

ID	Label	Type	Default
loopBody	Body	trigger	undefined
index	Index	number	undefined
done	Done	trigger	undefined

Configuration defaults

{
  "index": 0
}

Observed frontend behavior

This calls the production passive computation with the declared input/config defaults. Cached state, trigger execution and project wiring are separate.

{
  "kind": "passive-default-probe",
  "outputs": {
    "index": 0
  }
}

Observed backend behavior

Offline production passive computation with the same declared defaults; no device or model service is invoked.

{
  "kind": "passive-default-probe",
  "outputs": {
    "index": 0
  }
}

Current frontend implementation

Extracted production branches; helper calls and project execution context are defined in the referenced modules.

src/lib/execution-helpers.ts:236

case "forLoopNode":
      outputs.index = Number(config.index ?? 0);
      break;

Verification limits

• Default passive probe is an observation, not proof of all configurations, trigger behavior, or correctness. See ../NODE_RUNTIME_AUDIT.md and ../AUDIT_VALIDATION.md for test evidence.
• Trigger inputs schedule actions; passive evaluation alone does not execute those actions. Wire a trigger source and test the full chain.
