Why the second panel is the important one
A large z on marked text proves less than it appears to on its own, because any function that returns a big number for text produced by a particular generator would pass that test. The control is the same text scored under a different key. If the detector were responding to something about how the text reads, it would light up there too. It does not, because the statistic is a property of the key-text pair and nothing else.
The same pair of assertions is a test in the repository, so it runs on every change rather than only when someone visits this page.

- Published by NeverPrompted for verification and self-test. Not a model vendor key. It detects text marked under this published scheme only.
This key is public on purpose. It exists to make the method auditable, not to detect any real model’s output. It detects text marked under this published scheme and nothing else. What it demonstrates is that the machinery works, so that when a vendor or institution key is configured you know what it is doing. The method page explains why no vendor key is public.
