The Unification of Quantum Mechanics and General Relativity Cannot Be Completed Within Spacetime Under the GDUM Hierarchical Projection Architecture

Under the GDUM hierarchical projection architecture, general relativity and quantum mechanics are parallel projections of a pre-geometric topological structure onto the representational layer; spacetime itself is a classically read-out geometric stage and does not possess independent quantum dynamical degrees of freedom. Therefore, [within the GDUM axiomatic system], it is impossible to complete a field-theoretic unification of the two within the 4-dimensional spacetime manifold. Unification occurs in the computational-layer topological architecture prior to the emergence of spacetime.
