Paste anything. Get a receipt.

A paycheck stub, a store receipt, a nutrition label, an article full of numbers. The auditor finds every claim it can check with certainty, verifies each one deterministically — no AI in the loop — and seals the whole report so anyone can re-check it. It would rather miss a claim than check the wrong one.

What it checks (v1)

Explicit sums and products · percentages (“15% of 80 is 12”) · hourly pay (“40 hours at $18.50/hr = $740”) · salary ↔ hourly · compound interest (the word “compound” must appear — anything less is ambiguous, and ambiguity is skipped, not guessed) · rule of 72 · elapsed years (“4 years (1914–1918)”) · “July 4, 1776 was a Thursday” · leap years · nutrition labels (calories vs. the 4-9-4 macro math). The report always states how many claims it checked — it never implies it read everything.
