This paper introduces the Civilization Preservation Principle (CPP), a formal framework that models civilization as a dynamical decision system with measurable structural instability. Unlike traditional collapse theories, CPP defines preservation conditions mathematically through an integrated instability functional and a probabilistic failure model. The framework operationalizes structural entropy via reconstruction loss conditioned on decision traces, making explainability measurable and designable. Civilizational collapse is modeled as a phase transition governed by a critical threshold and a sharpness parameter linked to institutional redundancy. The CPP integrates entropy theory, dynamical systems, institutional stability, and audit-based reconstructibility into a unified preservation condition. It provides a mathematically defined boundary for civilizational stability rather than a descriptive narrative of collapse. This work establishes structural explainability as a necessary condition for long-term civilizational preservation.
