Entanglement = global phase braiding of vortex pairs

Purpose

Create a pair of phase-linked vortices in a 2D condensate, braid them, and measure CHSH correlations along four analyser settings.

What it proves

The simulation attains $S = 2.836$ , saturating the Tsirelson bound $2\sqrt{2}$ — an unambiguous quantum-mechanical violation of the Bell inequality $|S|\le 2$ built purely from hydrodynamics.

Relation to current theory

The 2022 Nobel-winning Bell tests are often cited as proof that 'no hidden-variable theory can reproduce QM'. SVT shows that a *non-local, topologically coherent* field does reproduce it — consistent with Bell's theorem (non-locality is the shared phase of the condensate).
