All records are fictional editorial exercises, not KitNelo traffic or AI-product test results. Source CSVs use the same English headers in both packs. Keep originals. Answer files are for comparison, not additional inputs.

Import orders.csv only in Sheet Batch. First preview without deduplication: 6 rows. Choose Order only: 4 rows, losing a valid product line. Restart from the original and choose Order+Line: 5 rows. Both blank Order records remain. Review the conflict; first-kept does not mean latest. Compare business columns with the answer files; optional provenance adds columns.
