Some Geometric Coincidences Between Spacetime Granularity and Quantum Structure: Questions Raised by QGDS

This paper is an honest verification exercise, not a derivation of quantum mechanics. It takes the ontology of Quantum Granodynamics of Spacetime (QGDS) — in which spacetime is a population of boundary 2-spheres separating two mirror three-dimensional domains, A and B — and asks whether features of quantum physics appear in that boundary by accident. From a single premise (that a particle's state lives on the A/B boundary, which is by construction a double cover), an unexpected number of independent quantum features fall into place: the exact singlet correlation E(θ)=−cos(θ) and its Bell value 2√2; spin-1/2 for matter and spin-1 for light from the same structure; the photon's two polarizations, masslessness, dimensionlessness, and zero proper time; the monogamy of entanglement; and a boundary-based reason why light needs no medium yet is not the discarded ether. These are presented as coincidences and directions — provocations for debate — not as results. None is a derivation. The complete corrected formulation of QGDS is the companion record (Zenodo DOI record 21740450), recommended reading first.
