Functional Stability Theory II: Chemical Stability and Autocatalytic Selection

A game-theoretic framework for prebiotic chemistry, interpreting autocatalytic networks, hypercycles, and chirality selection as Nash equilibria of thermodynamic games. Building on Dynamic Kinetic Stability (DKS) and the England inequality, we propose that the Maximum Entropy Production Principle (MEPP) serves as a stability filter—demarcating the viable manifold of replicating systems—rather than as a causal driver. Empirical motivation comes from Azoarcus ribozyme experiments, where RNA replication dynamics conform to classical payoff matrices (cooperation, dominance, Prisoner's Dilemma). Homochirality is explained as spontaneous symmetry breaking in a degenerate Nash equilibrium. Series position FST-II is the chemistry / autocatalytic stability companion (Level 1b) of the FST application series. The programmatic umbrella is the FST Hub (Concept-DOI 10.5281/zenodo.20130499). Sibling application companions: FST-I Particles, FST-III Biology, FST-IV Cosmology. Code FST-IV is now the cosmological collector slot. GitHub source link added.
