C² (Change = Change): A Reconstructive Hybrid Dynamical Framework for Survival, Adaptation, and Transformation

This work introduces C² (Change = Change) as a reconstructive hybrid dynamical framework that formalizes change as a self-referential and adaptive process. Departing from equilibrium-oriented and optimization-driven models, the framework conceptualizes survival, resilience, and transformation as continuous–discrete cycles of reconstruction. C² integrates nonlinear continuous dynamics with discrete reconstructive events, enabling the identification of critical thresholds, systemic vulnerability, and reconstruction capacity. The framework is proposed as a cross-domain conceptual platform applicable to complex systems in physics, socio-economic organization, artificial intelligence, ecological systems, and adaptive policy design. This deposit represents a formalized and extended development of the C² framework and is intended for open scientific use, citation, and further theoretical exploration.
