Based on logical origin as the first principle, we establish a closed axiomatic system and construct a 45° conical spacetime with general covariance. We rigorously prove that 45° is the unique stable inclination for rotationally supported growing structures, and the Pythagorean frustum is the only locally complete structural unit. This framework unifies gravity and quantum mechanics without divergences. Dark matter and dark energy are pure geometric effects. A logical barrier is proven between four-dimensional life and three-dimensional artificial intelligence. The theory is self-consistent, covariant, mathematically complete, and falsifiable.
