Matches a GaugeH2 report

These figures were registered in our database at the time the report was generated. Compare them against your PDF — any divergence indicates the PDF was modified after issuance.

What we check here is the content hash recorded when the report was issued, not a fresh run of the model. Recomputing that hash over the published payload reproduces exactly. Re-deriving the figures themselves may not: compound arithmetic is approximated differently by different engines and by different orders of operation, so the last digit can move — 1.02^3 comes out as 1.0612080000000002 one way and 1.061208 another. That divergence sits in the sixteenth significant digit and changes no conclusion in any report.

This page does not disclose the inputs of the calculation or who ran it. It confirms whether the fingerprint matches a record we hold, and shows the same summary printed on the PDF cover, headline result included.

How report verification works

Every report sealed by GaugeH2 carries a SHA-256 fingerprint of its bytes, registered when it is issued. This page computes the fingerprint of your PDF in your browser and looks it up in that register: the file itself never leaves your computer.

If a single byte of the report changed after it was issued, the fingerprint no longer matches, and the page says so.

Frequently asked questions

Do I need an account?

No. Verification is public and free, so that a bank or a client can check a report they have received.

What does a match show?

That the file is the one GaugeH2 issued and has not been altered since. It says nothing about whether the project’s assumptions are right: those are the ones declared by the author of the calculation.

Which reports can be verified?

The LCOH, TEA and Monte Carlo reports sealed by GaugeH2.
