Range (`rangeNode`)

Category: Control Flow

Intended behavior

Checks whether Value falls within Min/Max on Check, tracking a counter that increases when in range and decreases when out of range.

Inputs

ID	Label	Type	Unwired default
`value`	Value	number	0
`checkTrigger`	Check	trigger	undefined
`resetTrigger`	Reset	trigger	undefined

Outputs

ID	Label	Type	Default
`inRange`	In Range	boolean	undefined
`above`	Above	boolean	undefined
`below`	Below	boolean	undefined
`count`	Count	number	undefined

Configuration defaults

{
  "min": 0,
  "max": 10,
  "initialCount": 0,
  "count": 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": {
    "above": false,
    "below": false,
    "inRange": true,
    "count": 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": {
    "above": false,
    "below": false,
    "inRange": true,
    "count": 0
  }
}

Current frontend implementation

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

src/lib/execution-helpers.ts:245

case "rangeNode": {
      const value = Number(inputs.value ?? 0);
      const min = Number(config.min ?? 0);
      const max = Number(config.max ?? 0);
      outputs.above = value > max;
      outputs.below = value < min;
      outputs.inRange = !outputs.above && !outputs.below;
      outputs.count = Number(config.count ?? config.initialCount ?? 0);
      break;
    }

src/lib/execution-helpers.ts:430

if (type === "rangeNode") {
    if (targetPortId === "resetTrigger") {
      updatedConfig = { ...config, count: safeNum(config.initialCount) };
    } else {
      const value = Number(inputs.value ?? 0);
      const min = Number(config.min ?? 0);
      const max = Number(config.max ?? 0);
      const inRange = value >= min && value <= max;
      const current = safeNum(config.count ?? config.initialCount);
      updatedConfig = { ...config, count: inRange ? current + 1 : current - 1 };
    }
  }

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.
