This is Version 2 of the work, extending the original formulation into a four-dimensional structural framework. The paper introduces a structural integrity invariant (Ψ) for numerical systems, formalized through scale, distribution, spectral, and geometric components. A refined axiomatic formulation is presented, including explicit multidimensional expressions and a clarified 4D interpretation. This version supersedes Version 1 and should be considered the authoritative reference.
