GDG-QG-Certificate-VIII: Relativistically Readable Spacetime Emergence

23-Apr-2026(V1.1): GDG-QG-Certificate-VIII develops the next structural stage of the Gamma-DG quantum-gravity program beyond physical interpretability and structural realizability. This certificate studies whether the organized Gamma-DG bridge established through the previous certificates can support a relativistically readable spacetime-side regime under controlled bridge-to-spacetime admissibility conditions. In particular, it introduces and clarifies the notions of relativistically readable spacetime emergence, bridge-to-spacetime admissibility, and spacetime-side coherence. Version 1.1 sharpens the structural claim of the certificate by clarifying that spacetime-side emergence is not to be understood as a merely formal or externally projected image, but as an internally supported and structurally mediated consequence of the organized bridge. At the same time, the scope of the claim remains disciplined: this version does not assert a final relativistic spacetime theory, a unique spacetime model, or empirical completion. In this sense, Certificate VIII should be read as a threshold result in the direction of relativistically readable spacetime emergence within the Gamma-DG framework. 04-Apr-2026(V1.0): GDG-QG-Certificate-VIII develops the next stage of the Gamma-DG quantum-gravity program beyond physical interpretability and structural realizability. This manuscript studies whether the organized Gamma-DG bridge established through the previous certificates can support the emergence of a relativistically readable spacetime-side regime. To this end, it introduces relativistically readable spacetime emergence, bridge-to-spacetime admissibility, and spacetime-side coherence as central structural notions, and clarifies the conditions under which the bridge may support an admissible passage toward spacetime emergence. This certificate is presented as a threshold step toward a unified structural theory bridging the quantum-primitive layer and the relativistically readable spacetime layer through the principles of Gamma-DG.
