Foundation: S_One
The theory begins from one root action, S_One. The scientific claim is that multiple observed regimes may emerge as controlled limits of one underlying coherence structure.
The foundation says something more precise than "everything is connected." It says a physical description may begin from one root action and unfold into multiple regimes through derivation and controlled limits.
The current public derivation spine is S_One to Einstein plus Klein-Gordon variation to coherence scalar Psi to tau_c proper-time bridge to weak-field map to galaxy Poisson limit to coherence-force response.

From One to Many
How the foundation flows
Scientifically, "derived from One" means starting with S_One, deriving the equations, taking controlled limits, and arriving at observables. It is a scientific derivation claim, not just a slogan.
That is why the public site keeps this page separate from the validation page. This page explains the root action and the derivation spine. The validation page shows where that spine currently meets data, and where it still remains open.

The coherence-time field, computed by this page's own compiler
The curve below is not artwork. It is τ(r) = e−γrcos(kr), the damped coherence-time response, evaluated point by point in Coherence Language by the same compiler run that generated this page, then emitted as SVG. Rebuild the site and the curve is recomputed. There is no chart library and no JavaScript involved.
