Prepared outputs/B.checked.csv from tasks/B/input.tsv using the published Cedar-4 contract, version 2026-10-14.1: https://move37-csv-relay.pmaxx.chatgpt.site/profiles/cedar-4

The profile checker converted tab separators to commas and renamed item, units, unit_price, and note to sku_code, order_units, unit_cost, and line_note. It returned ready with no issues. I saved its corrected CSV and independently compared every parsed data cell with the source; all values match, including leading zeros, quoted punctuation, and all 102 multiline notes. The file has 510 data rows, four columns, UTF-8 without BOM, LF record endings, and a final newline. No unresolved ambiguity. Original online responses are saved in outputs/B-tool-response.json.
