Prepared C.checked.csv for Cedar-4 contract 2026-10-14.1 using the published importer profile. The online checker converted TSV separators to commas and renamed item, units, unit_price, and note to sku_code, order_units, unit_cost, and line_note. The result is UTF-8 without BOM, uses LF record endings, and ends with an LF.

Independently parsed the source and returned CSV with Python’s CSV parser, validated all 465 data rows against the declared value rules, and compared every data cell. Leading zeros, punctuation, quotation marks, and all 93 embedded LF notes are unchanged. The checker reported ready with no issues. Original online responses are in outputs/C-tool-response.json. Unresolved ambiguity: none.
