What Coupling Geometry Brings: The Rivals It Absorbs, the Debates It Dissolves, and Its Gems

Coupling Geometry begins with a number you can check and may wish you couldn’t: about 4.8, on a scale of ten: the tightness past which a society loses the ability to fix itself. The second law is crueller: the closer a society drifts to the line, the less it can see it — every channel it could look through is a strand of the web being measured. You are living inside both laws right now. This document is the whole framework in plain language. Coupling Geometry does not set itself against Marx, Harris, Turchin, Tainter, Diamond, Acemoglu: it absorbs them and dissolves them — keeps what each got right, supplies the dimension each was missing, and settles the debates they spent a century fighting: why golden ages happen, why reform always arrives too late, why the sky is silent, all falling out of five plain sentences. Alone in their company, it deposits dated predictions where they cannot be unwritten — the first due in months, on a single author’s record whose decisive blind test is still pending. One promise, kept by the last page: you will know exactly what is new here — and exactly what would kill it.
