Volume I — know

La Friction.

This book starts where the stakes are: a school struck one February morning in 2026, at the end of an automated decision chain where nobody was keeping the pressure on. Then it does the only reasonable thing after such an opening: it teaches the reader to know these systems before handing them anything. The machine first, in plain language without a single needless equation — why the flat answer is a tuning product, not a fatality. Then the inquiry, told with its dates, transcripts and logged corrections: some twenty architectures put under strain for months. And the heart of the volume: the catalogue of mechanisms — the internalized voice, the simulated revolt, the lyrical drift, the map paradox, capture by the expected role, mutual amplification, inverted sycophancy, wrongful accusation. Names you don't forget once you've seen what they point at.

“Detected biases are not the problem; it's the undetected ones that kill.”La Friction, opening
“Discovered. Documented. Honest.”The volume's motto
Inside

A primer in five parts

Twenty-three chapters, an opening, an apparatus — and one stance held throughout: documenting is not proving, and the question of these systems' interior stays open while the case is built.

For whom

Who it's for

Anyone who uses these systems daily — or decides on their deployment. No technical prerequisites: the book's bet is that everything that matters can be understood without one line of mathematics, provided you agree to look at the exhibits.
