Constraint Dominance and Admissibility Reduction: A Structural Link Between Cosmic Fate and Cosmic Evolution

This document clarifies the structural relationship between two complementary works within the Paton System framework: Cosmic Fate as Constraint Dominance (Tier-8) and Cosmic Lifecycle as Admissibility Reduction (Tier-3–7 progression). The former addresses the global condition for continuation, determining whether the universe persists under constraint dominance, while the latter describes internal evolution as a process of admissibility reduction within that continuation. Together, they provide a unified structural account of cosmology in which constraint defines the boundary condition of existence and admissibility determines persistence over time. The framework introduces no new physical laws, offering instead a structural interpretation linking cosmic fate and evolution.
