List Get (`listGetNode`)

Category: Lists

Intended behavior

Reads one entry by index. Negative indexes count back from the end (-1 = last).

Inputs

ID	Label	Type	Unwired default
`list`	List	any	[]
`index`	Index	number	0
`enabled`	Enabled	boolean	true

Outputs

ID	Label	Type	Default
`item`	Item	any	undefined
`found`	Found	boolean	undefined

Configuration defaults

{}

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": {
    "item": null,
    "found": false
  }
}

Observed backend behavior

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

{
  "kind": "passive-default-probe",
  "outputs": {
    "item": null,
    "found": false
  }
}

Current frontend implementation

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

src/lib/list-node-compute.ts:58

listGetNode: (inputs) => {
    const list = toList(inputs.list);
    const raw = Math.trunc(toNum(inputs.index));
    // Negative indexes address from the end, like Python/JS slice semantics.
    const idx = raw < 0 ? list.length + raw : raw;
    const found = idx >= 0 && idx < list.length;
    return { item: found ? list[idx] : null, found };
  }

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.
Enabled=false uses the runtime bypass mapping; bypass output can differ from the normal declared output type.
