Published measurements

Readings.

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.

The Instrument Reading · July 2026

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.
