This paper presents a phenomenological geometric framework that reproduces the strange-baryon spectrum, charged lepton hierarchy, and neutron–proton mass difference using a remarkably small set of recurring scales and geometric factors. The same structures also appear in several exploratory nuclear and hadronic observables. Rather than proposing a complete theory, the paper documents a series of unexpected numerical regularities and asks whether they point to an underlying geometric organisation of particle masses.
