The Yukawa Spectrum Classified: Parameter Smallness with a Power-Law Organiser, Not Demonstrated Accumulation

The nine charged-fermion Yukawa couplings span 5.529 orders of magnitude, from y_e = 2.94e-6 to y_t = 0.992. A Froggatt-Nielsen style ladder with a single expansion parameter epsilon = 0.22 and minimal integer charges (8, 7, 7, 5, 5, 3, 3, 2, 0) reproduces the spectrum with an RMS residual of 0.180 dex and a worst case of a factor 2.02. A Monte Carlo comparison shows 40.4 percent of random log-uniform spectra in the same range fit the ladder at least as well, and the ladder replaces nine continuous inputs with nine discrete inputs rather than fewer inputs. The spectrum is therefore classified, extending an earlier classification of the strong CP problem, as parameter smallness with a power-law organiser, not demonstrated accumulation.
