What the verifier stands behind.
- Check it without the vendorNo vendor needed A plain Python install re-checks any record on your own machine.Plain Python, your own machine. Runs today
- Proof, not opinion The check settles whether the answer matches what was claimed, not whether the call was right.The claim, not the call. By design
- An ERROR is never an OKERROR is never OK OK, REJECT, or ERROR. If the tool can't check it, it says so. Never a quiet OK.OK, REJECT, or ERROR. Never fakes an OKNo quiet OK
- Trust neither side The maker can't ship the code that grades it. And anyone else can re-run the check and sign off.The maker can't ship the grading code. By design
