Beta differentiation and hydrogen closure

Beta decay is the weak-sector rearrangement of the neutron regime, not the breakup of an already ordinary particle into independent primitive actors. It generates the proton, electron, and neutrino readouts: the proton is the residual bulk/core mode of the neutron regime, the electron is the corresponding surface/co-rotor mode, and the τ^1 time-mode, carrying the beta-minus antineutrino label before the Majorana/helicity readout of Step 50, is emitted along the base direction. Hydrogen is then the first stable coupled proton – electron unit: the first atomic co-rotor regime rather than a mere aggregate of two independent substances. The exact co-rotor terminology should remain anchored to the Book-IV/Book-V source map.
