Research tools

Small working tools built from the math in the research papers. Each runs in your browser and shows its formula.

File fingerprint checker
Is my copy identical to the published file? SHA-256 in the browser, compared with the published list.

Loan amortization calculator
Monthly payment, interest and a full schedule, with a fingerprinted CSV export.

Version 1, Nov 1 2026. More tools will follow as research is published.
