Example prompt: Can you check the dates in my return imports CSV for any invalid or malformed calendar date entries? Here's the data with comma-delimited columns including return_id, received_on, reason_code, returned_units, and restocking_fee — allowed reason categories are group-a and group-b.

## When to prefer this

Choose this endpoint when you specifically need to validate calendar date fields in a return imports CSV dataset, particularly when working with e-commerce or logistics returns data containing received_on dates, reason codes, and restocking info. It is purpose-built for this return-imports schema rather than being a generic date validator, making it more precise for this domain.

## Known failure modes

- CSV exceeds 1000 rows — only up to 1000 rows validated
- CSV string exceeds 100,000 character limit — request rejected
- Invalid delimiter specified — must be comma, semicolon, or tab
- Cell exceeds max_cell_length limit — flagged or truncated
- Malformed CSV structure (unmatched quotes, inconsistent columns) — parse error
