McCaul's Law of Coherence: Particle Accelerator Precision Tests of E=mΦ²c² and Double-Slit Fringe Visibility Experimental Protocol (Triple-Verified)

Part I: Triple-verified simulation of E=mΦ²c² against CODATA 2018, CERN LEP, Fermilab Muon g-2 final 2025 (127 ppb). Five tests with honest error accounting: electron g-2 (1st order confirmed, 2nd order open problem), hydrogen spectral lines (algebraically exact), muon g-2 direction confirmed (tau prediction δa_τ=1.63e-8 for Belle II/FCC-ee), W boson universal Φ_EW falsified by M_Z (37.7σ, three viable interpretations remain), proton charge radius direction confirmed. Part II: One-page experimental protocol for V=(Fg-Nr)/(Fg+Nr) double-slit test using Walborn polarization scheme. Key prediction V=0 exactly at Nr=Fg, distinguishable from standard QM. Equipment ~$15k-40k, 4-8 weeks to result. Explicit falsification criteria.
