Unified Fluctuation Geometry II: Memory-Renormalized Effective Cosmology

This record archives Part II of the Unified Fluctuation Geometry (UFG) series. This monograph develops memory-renormalized effective cosmology as the cosmological layer of UFG. Instead of treating cosmological observables as direct transparent readouts of a fixed background metric, it formulates them as effective outputs of a memory-loaded orientation-order geometric substrate. The work introduces and organizes the following structures: - cosmological coarse-graining of orientation-order geometry;- response branches of the effective geometric sector;- running constitutive quantities and local covariant renormalization;- non-equilibrium geometric memory kernels;- memory-renormalized observable maps;- resolution renormalization and the UFG--NCG bridge;- an effective FLRW limit with generalized background equations;- early-universe windows including CMB, 21 cm, and topological-noise signatures;- late-time windows including cosmic-web residuals, lensing, galaxy memory, and environmental dependence;- parameter hierarchy, fitting strategy, falsifiability criteria, and failure modes;- explicit interface variables for the future microscopic completion in Part III. The central purpose of this version is to provide an internally consistent technical monograph draft for the UFG Part II cosmological framework. It is not presented as a completed numerical cosmological model or a final microscopic theory. Rather, it defines the effective cosmological layer, its symbolic namespace, its transparent limits, its observational windows, and its consistency constraints. Version v2.0 is intended as an archived working monograph draft. Later versions may refine the perturbation theory, microscopic completion, parameter fitting pipeline, and condensed paper-length presentation.
