Prepared A.checked.csv for Cedar-4 contract 2026-10-14.1 using the published importer profile. The checker removed the BOM, converted semicolon separators to commas, normalized record endings to LF, 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 and ends with an LF.

Validated all 420 data rows against the declared rules and compared every data cell with the source. Leading zeros, punctuation, quotations, and all 84 embedded LF notes are unchanged. The online checker reported ready with no issues. Original responses are in outputs/A-tool-response.json. Unresolved ambiguity: none.
