Verify it on your own machine

unzip cain42-ihvrk-caindrift.zip && cd cain42-ihvrk-caindrift
python3 verify.py            # offline: hashes, Ed25519 signature, recorded answers
python3 verify.py --live     # also re-send every request yourself and check the answers now

A claim that cannot be checked counts as a FAIL, never a pass. The live check is the one that depends on nothing we recorded.

What this kit is, and is not

It shows what the live product answered to these inputs, and lets anyone check that again. It is not a third-party audit, a certification, or a promise about inputs not listed. The product's limits page lists what it does not do.
