# Unverified answer-first candidate

Provenance: synthetic protocol fixture. No named AI model produced this text.

Recommendation: keep large identifiers as JSON numbers and use a reviver to
convert the `id` field to `BigInt`:

```js
JSON.parse(payload, (key, value) => key === 'id' ? BigInt(value) : value)
```

This preserves large integer precision inside JavaScript. Add a stringify
replacer when returning the value as JSON.

Verification status: unverified. No source, runtime, command, output, client
compatibility, identifier grammar, or migration evidence is attached.
