Bilig
Keep the workbook model. Run the rule in Node.
Bilig is a TypeScript-native, headless WorkPaper runtime for Node.js services, tests, and AI agents. Set inputs, recalculate formulas, read computed outputs, persist WorkPaper JSON, restore it, and verify the result—without driving Excel or a browser grid.

Заметка
Bilig is a headless workbook runtime, not a visual spreadsheet app or a claim of full Excel compatibility. If an
.xlsxfile is your contract, start with the compatibility report.
Quick Start
Node runtime
Prove the published package before installing it:
npm exec --yes --package @bilig/workpaper@latest -- bilig-evaluate --door workpaper-service --jsonThe evaluator edits Inputs!B2, recalculates Summary!B2, saves the WorkPaper,
restores it, and compares the restored value:
{
"schemaVersion": "bilig-evaluator.v1",
"door": "workpaper-service",
"evidence": {
"editedCell": "Inputs!B2",
"dependentCell": "Summary!B2",
"before": 24000,
"after": 38400,
"afterRestore": 38400
},
"verified": true
}
