Local classical wirings of biseparable quantum correlations can create genuine multipartite nonlocality—revealing instability of current GMNL definitions and questioning their operational validity in quantum information theory.

Constructed explicit wedge-local observables proving CHSH violations at 2.060+ in relativistic scalar QFT through spectral-fibre Cliffordization and finite-band optimization of translation/reflection involutions.

First Bell inequality violation using motional states of massive particles. Momentum-entangled helium atoms achieved CHSH parameter S=2.52±0.17, extending quantum nonlocality tests from internal properties to external degrees of freedom of matter waves.
