10.15 Material Realm Contraction Time

We establish sublayer spectral analysis, three-dimensional volume traversal scaling, and holographic reconstruction construction, deriving the material realm contraction time, the cosmic radius, and the purely geometric spatial measure. Core results: cosmic radius billion light-years, deviating from the observed comoving radius of 465 billion light-years by approximately 1.2%; the electron characteristic length m, deviating from the standard Compton wavelength by 0.06%.
