The Tsirelson Bound as Measurement Geometry of the Existence Equation

Evidence Paper VI. The Tsirelson bound S_max = 2√2 is decomposed into two structural factors: 2 (Bob's two unit measurement vectors) × √2 (diagonal of Alice's 2D optimization space). The geometric ceiling 2√2 exists for all theories including classical ones; reaching it requires cos(θ) correlations from a single conserved field. Verified numerically to 10⁻¹⁶ precision in 2D, 3D, and 10D. The Bell violation is not non-locality — it is the geometry of discrete binary measurement.
