Verify it on your own machine

unzip cain42-ihvrk-codeguard.zip && cd cain42-ihvrk-codeguard
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.
