Filter (filterNode)

Category: Data & Text

Intended behavior

Passes the value through only when it includes (or excludes) the search text.

Inputs

ID	Label	Type	Unwired default
value	Value	any	""
search	Search	string	""
enabled	Enabled	boolean	true

Outputs

ID	Label	Type	Default
out	Out	any	undefined
match	Match	boolean	undefined

Configuration defaults

{
  "mode": "include",
  "caseSensitive": false
}

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": {
    "match": true,
    "out": ""
  }
}

Observed backend behavior

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

{
  "kind": "passive-default-probe",
  "outputs": {
    "match": true,
    "out": ""
  }
}

Current frontend implementation

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

src/lib/execution-helpers.ts:207

case "filterNode": {
      const val = inputs.value;
      const search = String(inputs.search ?? "");
      const hay = typeof val === "object" && val !== null ? JSON.stringify(val) : String(val ?? "");
      const found = config.caseSensitive
        ? hay.includes(search)
        : hay.toLowerCase().includes(search.toLowerCase());
      const pass = (config.mode ?? "include") === "include" ? found : !found;
      outputs.match = pass;
      outputs.out = pass ? val : null;
      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.
• Enabled=false uses the runtime bypass mapping; bypass output can differ from the normal declared output type.
