Agent Verifier — Independent Number Verification

Verify that the numbers in a finished table add up — before you deliver it. Use this when you have produced or received a table, spreadsheet, CSV/TSV or markdown table, a cost breakdown, invoice, quotation or budget, and need an independent check that row totals, column totals and subtotals are arithmetically consistent, or that a list of line items sums to a stated total. Returns every mismatched cell with the recomputed value and the difference, plus a signed verification receipt (verification ID, UTC time, SHA-256 content hash). Checks arithmetic consistency only; does not verify source data. Not a calculator — it does not evaluate expressions; it audits finished numbers.
