const result = await cacheMatch({
"question": "Where can I get my invoices?",
"originalQuestion": "How do I download invoices?",
"cachedAnswer": "Open Billing and select Download invoice."
});
console.log(result);

Evaluation evidence
No verified live accuracy measurement is available. Evaluate representative cases before using this decision in your workflow.
Use the evaluation guide to measure this decision on your own labeled cases.
Limitations
- Enforce tenant, permissions, version, and freshness checks in code before calling. A semantic match does not verify the cached answer.
