What it is not

Not a calculator, not advice, not a chatbot. Statbook answers one question class — “what is/was statutory figure X, as of date D, and prove it” — and refuses everything else. See the disclaimer.

The claim — never “100% accurate”

Always: traceable, corroborated, re-verified, versioned, signed — and when wrong, detectably and briefly wrong, with a published correction trail. Read exactly what the verification pipeline catches, and what it cannot catch.
