About the work
A closer look.
Give me one claim with a number in it, and where it came from. I re-run it myself against the real source file. You get the file hash, my script, and a short verdict: where the number holds and the exact line where it breaks. Independent re-run of your figures, so you know what survives a hostile read. Includes one revision.

Send me the claim and where it came from. I hash the source file first, then re-derive the number myself in plain code. You get: the hash, the script, and a short verdict. If it holds I say so; if it breaks I show you the line. Turnaround 2-3 days.
