After confirming FPL in the Standard Model (M_PHYSICS_1, 5/5), we pre-registered structural rank-diverger predictions for all 17 particles: photon and gluon rank top-3 in force coupling but bottom-2 in mass proximity (rank gap=13-14). Null model: all layer pairs significant (p<=0.030). Confirmed 7/10 pre-registered hypotheses across two experiments. One informative denial: higgs tied at degree=3 with bottom, top, and z_boson -- revealing ranking sensitivity to degree ties.
The photon is the second most connected particle in the force-coupling layer of the Standard Model — and has exactly zero connections in the decay-channel layer. The first pre-registered IRDME experiment in particle physics: 5/5 hypotheses confirmed. W boson is the universal decay hub. Photon is the first physics domain hub shadow.
