Abstract

The foundation paper in the Information-Persisting Systems (IPS) programme. This manuscript develops a physical theory of information-persisting systems (IPS): bounded, far-from-equilibrium patterns whose identity is preserved by active information processing. It combines non-equilibrium statistical mechanics, stochastic thermodynamics, Landauer's principle, and the variational free-energy principle into a single dimensionless persistence ratio ℛ (the Fractal Persistence Equation). Main results: - ℛ ≥ 1 is a necessary condition for long-term persistence (Theorem 5.1) - Model error (KL divergence between internal model and environment) imposes an exponential lifetime penalty (Theorem 5.2) - Persistence at one organisational level composes fractally with persistence at adjacent levels (Theorem 5.3) The theory is substrate-neutral and applies across scales — from nuclear binding and autocatalytic chemistry to cells, ecosystems, firms, and polities — as a single thermodynamic accounting identity. Five falsifiable predictions (P1–P5) are stated, including a substrate-isolation forgetting law testable in fractal mixture-of-experts networks. This is a physics paper, not a metaphysics of consciousness. Companion work on agent systems and implementation lives at https://aion.anomalia.io/
