Addendum to SR–SE: Geometric Interpretation of Structural Entropy Saturation Across Cosmology and Quantum Phenomena

This document is an addendum to the manuscript DOI:10.5281/zenodo.18131544 It does not replace the original work and does not introduce new axioms or free parameters.Instead, it provides: • a geometric interpretation of the universal coherence factor Φ,• an extension of the SR–SE framework to cosmological observables (Hubble tension, dark energy),• a compatible modification of the Friedmann equation in which the cosmological constant is interpreted as a relaxation function Λ(Φ),• a structural interpretation of quantum phenomena as informational projection effects. This addendum is intended as a conceptual and interpretative extension of SR–SE, clarifying its geometric meaning and cross-scale coherence.It does not claim formal proofs of the Millennium Problems, but proposes a physically consistent mechanism explaining why singularities and divergences do not manifest in realized physical systems.
