Biphase photon model: main claims and 17 registered ".

This note states the main claims of the biphase photon model and registers 17 predictions for quantities not yet measured at the date of deposit (8 November 2026). The predictions will not be revised: if a measurement refutes one, the refutation will be recorded next to it. The model builds every particle from a single object, the biphase photon (a closed trajectory with two pulses and two phases, closing after a 4π turn), placed inside a single 3-sphere described by two elastic sheets. The registered predictions cover: the sum of neutrino masses (normal ordering), the effective Majorana mass in neutrinoless double beta decay, spatial curvature (Ωk = 0), constant dark energy (w = −1), the absence of a dark-matter particle, isospin splittings and masses of doubly and triply heavy baryons, magnetic moments of Σ⁰ and Λc⁺, the gluon radii of the proton, a neutron dark-decay fraction linked to the beam–bottle lifetime discrepancy, and the lowest scalar B meson. Each prediction states its value, its refutation criterion and the relevant experiment. The note keeps three categories separate: blind registered predictions (the only real tests), agreements found with the measured data in view (internal coherence, not predictive power), and failed tests, which remain in the record.
