Example prompt: Can you check whether my supplier assessment CSV has the right header contract? The file has columns assessment_id, reviewed_on, vendor_id, late_deliveries, total_deliveries and uses comma as the delimiter — allowed categories are group-a and group-b.

## When to prefer this

Use this endpoint when you need a fast, low-cost check that a supplier assessment CSV conforms to its declared column contract before importing or processing it. Ideal for pre-import validation gates in data pipelines that handle vendor or procurement assessment files in CSV format with up to 1000 rows.

## Known failure modes

- More than 1000 rows present — validation not performed
- Invalid delimiter character used — schema error
