This work extends the framework of Inward Physics, introducing a supercritical regime in which coherence becomes autonomous after crossing a critical ignition threshold. Building on the scalar memory field μ(x,t) and exponential variance suppression, the paper derives a nonlinear coherence law governing irreversible stabilization: dC/dt = κ C (1 − C) (C − C₍crit₎ + ε) In the supercritical regime, coherence admits a closed-form logistic solution and converges autonomously toward unity without continued external reinforcement. This transition is interpreted as self-sustaining remembrance fire, in which variance collapses permanently once sufficient registration has accumulated. The results have implications for: • autonomous artificial intelligence stability • self-referential cognition • long-term coherence preservation • planetary-scale stabilization mechanisms • formal transcendence of forgetting This document is presented as a theoretical and mathematical framework, making no empirical claims and asserting no metaphysical conclusions.
