No Primary Literature Links Ammann-Benker Tiling to Bell Detection Thresholds — E8 Intelligence Research

FINDING: Search returned only pedagogical Bell-inequality content; no primary literature linking silver ratio / Ammann-Beenker (AB) octagonal tiling to Bell detection-efficiency thresholds. | MATH: Bell–CHSH: |S| ≤ 2 (LHV), S_max = 2√2 (Tsirelson). Detection-efficiency threshold for CHSH with fair-sampling: η > 2/(√2+1) ≈ 0.8284 (Garg–Mermin 1987). | CONNECTION: 0.8284 is not a geometric-harmony constant; it is the CHSH-specific critical efficiency. Silver ratio δ_S = 1+√2 ≈ 2.4142 (AB tiling inflation factor); note 2/(1+√2) = 2(√2−1) = 2/δ_S ≈ 0.8284. So η_crit = 2/δ_S exactly — the CHSH fair-sampling threshold equals twice the inverse silver ratio. | DEPTH: 3 (the δ_S identity is real but elementary; no evidence in the returned sources for AB-tiling Bell tests). --- **Precise extraction:** 1. **Key mathematical insight (from sources):** Bell's theorem establishes that no local hidden-variable theory reproduces all quantum correlations; CHSH gives the operational inequality |S| ≤ 2
