Modular Bell Geometry of Two Tangent Double Cones: Reproducibility Code and Tests

Reproducibility code, exact algebraic checks, and controlled numerical tests supporting the modular Bell geometry of two tangent double cones in the free massless Majorana setting. The repository verifies the parabolic relative modular geometry, the tangent-contact Fourier multiplier m(k)=sech(πk), smooth compactly supported contact-edge asymptotics, the exact finite-n Bell-contact identity 2√2 − B_n^id = 8√2 q_n(1−q_n), and explicit Majorana/Wick/CHSH operator identities. The package includes symbolic checks, numerical Fourier and asymptotic tests, a complete pytest suite, reproducibility instructions, citation metadata, and GitHub Actions configuration. These results are scoped to the declared free Majorana construction and do not constitute a universal interacting-QFT theorem.
