This paper upgrades and unifies the mathematical foundation (V8.82) and physical foundation (V8.81) under Pythagorean Frustum Unified System II (V11.4). It reconstructs ring–number theory and unified field theory using only Primitive 1, 1°, 0, β₁, and five-element cyclic closure, forming a closed, consistent unified foundation.
