Part 35: Phenomenological Comparison Between Relaxation Cosmology in Dual–h₄ Geometry and Standard Λcdm Cosmology

Previous Parts established an emergent cosmological framework within Origin Geometry (OG), in which cosmological expansion is interpreted as a coarse-grained consequence of: topological relaxation, geometric stress redistribution, and collective bulk dynamics within the dual–H₄ network. The present work investigates the phenomenological similarities and differences between: relaxation cosmology in Origin Geometry, and standard ΛCDM cosmology. Unlike ΛCDM, where expansion is primarily described through: metric dynamics, matter density, radiation, and a dark-energy sector, the OG framework considers: geometric stress, obstruction topology, and bulk collective relaxation as coarse-grained ingredients that may contribute to effective expansion dynamics. This paper does not seek to: reject ΛCDM, or claim that OG replaces standard cosmology. Instead, its objective is to identify: phenomenological overlap, potential differences, and avenues of falsifiability between the two frameworks.
