# JSONL invalid-row repair checklist

- Keep the original file and count physical lines from 1.
- Record the original line number for every valid, malformed, and empty line.
- Diagnose the error before proposing a repair.
- Keep the original malformed line beside the repaired candidate.
- Ask the data owner to review the candidate before handoff.
- Do not silently discard an invalid or empty line.
- Re-run the receiver's JSONL validation after approval.
