A number without a proof is an opinion with a dollar sign.
A foundation’s sealed 990-PF, its filed years read in order, a board pack: each carries a proof, a hash over exactly what was sealed. Paste one here. The ledger says whether it knows it and when it was first recorded, and nothing else.
On the ledger: a proof of a foundation’s filed Form 990-PF.
The foundation’s own return for the tax year ended 2025-08-31, its arithmetic re-done exactly, first recorded 2026-09-28. It belongs to no family: every figure comes from the return the IRS published, and the proof page shows them all.
This page confirms the hash is on the ledger. It does not say who asked for it; the ledger does not know.

A recorded decision is a file the committee keeps. Choose it: this page says whether its words are the ones recorded, and on what date, without the words ever leaving your browser.
The file is read in this browser. Only a fingerprint of a fingerprint is looked up; the decision is never sent.
