Recursion-to-Geometry Bridge

Recursion-to-Geometry Bridge is the correspondence by which the First Fold's algebraic stability, F(n) = 1, is matched by geometric stability through the Pulse Radius L⥂. Folding is not only symbolic but spatial. The Pulse Radius supplies the curvature that lets recursion fold instead of collapse: it sets the arc on which recursive growth is redirected (containment), and each fold must fit within L⥂ to stay bound (stability). The Pulse Radius is thus the geometric skeleton of the fold, anchoring algebraic unity in physical scale. It connects to Pulse Radius, UniSpheral First Fold Function, Mathematical Derivation of Unity Convergence and Lyapunov Exponent.
