Gamma-DG and the Quantum–Spacetime Bridge: Toward a Unified Structural Theory

13-Apr-2026(V1.0): Gamma-DG and the Quantum–Spacetime Bridge: Toward a Unified Structural Theory This paper develops an original structural framework, Gamma-DG, for the quantum–spacetime bridge. The central problem is not merely how to connect a quantum-primitive foundational layer and a relativistically readable spacetime layer, but how to describe a controlled, admissible, and structurally coherent passage between these distinct regimes. The paper formulates a unified perspective in which bridge formation, bridge validation, and bridge culmination are treated as successive aspects of a single theoretical program. Core I and Core II provide the foundational basis of the framework, while the present paper focuses on the minimal structural ideas needed for the current synthesis.
