Check a file. Every result is free.

Attach a file, say in plain words what must be true about it, press one button. You get the verdict back. ESTABLISHED, FAILED, and UNKNOWN cost the same: nothing.

The rule: this check is free. The verdict is not for sale. A registered review is CAD $250 flat, the same fee for ESTABLISHED, FAILED, and UNKNOWN. Priority scheduling is CAD $100 and does not change the fee. See the open offer.

Plain answers

What does this check cost?

Nothing, whatever the verdict. It runs your statements against your file and returns the verdict, the fingerprint, and the reason. It is not an invoice.

What is paid?

A registered review is CAD $250 flat. The fee is the same for ESTABLISHED, FAILED, and UNKNOWN. Payment buys the work of testing, reproducing, and documenting the claim. It does not buy a verdict. Priority scheduling is CAD $100 and only changes the start slot. The terms are on quantumpiforge.com/open.

How do I know the result is honest?

Re-fingerprint your file and compare with the evidence package. Re-run the statements. The verdict must match — no trust in us required.
