Our deterministic mechanism for physicality has simple rules, from which other detail emerges:

1. Waves are bound in pairs as oscillators (bosons);
2. Quanta propagate radially, with equivalence of phase, distance, and time, $d\phi =ds=dt$, implying only light-speed propagation.
3. Waves are excluded from interactions when they have the same phase and source;
4. A boson's mass-energy is a function of its phases, $\rho =-b{e}^{-i\left({\phi }_B-{\phi }_A\right)}$
5. Other sources' waves are phase-modulated by $\rho$;
6. Bosons collapse into a fermion where waves from two different bosons have value $-b$ at a unique point.
