Everything in this section is a measurement we ran, published with its data, method and caveats. No opinion pieces, no "five tips" listicles: if an entry exists, there is a dataset behind it and a date on it. When a reading goes stale, the date says so before we do.

We measured our own measuring stick
Our classifier is an AI reading AI answers. So we fed it the same answers repeatedly, over two days: it disagrees with itself ~1%, and gives the same verdict on the same answer 24 hours apart 99.5% of the time, against the 19% volatility we report in the engines. The wobble is the machines, not our tool.
