Abstract

Introduces the CLEO framework as a minimal effective law for late-time cosmic acceleration, based on bounded nonlinear dynamics with activation and saturation under causal and entropic constraints. The formulation emphasizes interpretability, minimality, and direct connection to observational expansion histories.
