Quantum Mechanics Confirmed as Fundamental Ontology by Bell Violations — E8 Intelligence Research

FINDING: The 2025 Nobel Prize in Physics (Aspect, Clauser, Zeilinger lineage) and MIT single-photon experiments confirm quantum mechanics as the fundamental ontology — no hidden variables, no classical substrate. | MATH: Bell's inequality violation: \\(S = |E(a,b) - E(a,b') + E(a',b) + E(a',b')| \\leq 2\\) (classical bound) vs. quantum maximum \\(2\\sqrt{2} \\approx 2.828\\). Photon polarization correlation: \\(E(a,b) = \\cos(2\\theta)\\). Single-photon interference: \\(P(\\theta) = \\cos^2(\\theta)\\) (Malus's law). | CONNECTION: The \\(2\\sqrt{2}\\) Tsirelson bound is the maximal quantum violation — geometrically, this is the ratio of the diagonal of a unit square to its side (\\(\\sqrt{2}\\)), appearing in crystallographic root system \\(B_2\\) (square lattice) and \\(D_2\\). The \\(\\cos^2(\\theta)\\) law encodes the 4-fold rotational symmetry of the square — a direct link to base-60's 90° quadrant division and the 0.7071 (\\(\\sqrt{2}/2\\)) ratio, which is the half-diagonal of the unit square.
