The Cryptographic Horizon Model

This document defines a novel thermodynamic model for the structural stabilization, data conservation, and cyclic evolution of primordial cosmic engines. This model introduces a Fixed-Volume Macro-Boundary Condition governed by a dynamic density differential equation, wherein an isolated system's parent containment radius remains constant while internal localized core density is regulated via a fractional ejection valve. Global system resets are governed strictly by external macro-collisions with equivalent cosmic containers, and all internal structures are mathematically insulated from external falsification via a cryptographic event horizon.
