List Contains (`listContainsNode`)

Category: Lists

Intended behavior

Checks whether a list holds the given value, reporting the index where it was found.

Inputs

ID	Label	Type	Unwired default
`list`	List	any	[]
`value`	Value	any	0
`enabled`	Enabled	boolean	true

Outputs

ID	Label	Type	Default
`out`	Contains	boolean	undefined
`index`	Index	number	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": {
    "out": false,
    "index": -1
  }
}

Observed backend behavior

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

{
  "kind": "passive-default-probe",
  "outputs": {
    "out": false,
    "index": -1
  }
}

Current frontend implementation

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

src/lib/list-node-compute.ts:130

listContainsNode: (inputs) => {
    const list = toList(inputs.list);
    const needle = toStr(inputs.value);
    // Compared as text so a wired number 5 matches a typed "5" — the same
    // tolerance the Compare and Expected Value nodes already apply.
    const index = list.findIndex((v) => toStr(v) === needle);
    return { out: index !== -1, index };
  }

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.
