The Electron as a Double Vortex. An Ontological Image for Spin, Charge, and Wave

Established quantum formalisms represent electron spin-$1/2$, its 720^∘ periodicity and its magnetic response with extraordinary precision. This paper addresses the complementary ontological question: what physical organisation of the electron could produce the properties represented by those formalisms? Bhabha-scattering measurements constrain detectable electron structure through an upper bound rather than selecting zero extension, thereby leaving an experimental interval within which alternative anatomies remain admissible. We postulate that the electron is a double vortex: an extended structure formed by two coupled counter-rotating vortices with charge concentrated in a central point-like region. This single anatomy provides a proposed structural reading of the 720^∘ cycle, the simultaneous presence of extended and concentrated behaviour, the twofold orbital capacity expressed by Pauli exclusion, and the coexistence of Schr\"odinger's extended evolution with Born's local statistical manifestation. It also proposes a physical origin for the $g=2$ signature represented by Dirac's formalism. These connections constitute the framework's backward fertility. Its forward fertility includes a corrected analysis of the charged-mode mass hierarchy: the observed logarithmic separations contract by a factor λ≈0.52938, whose conditional continuation yields a quasilepton target near 7.92\,GeV. A possible differential response in inhomogeneous magnetic fields and the future classification of admissible topological configurations provide further routes for discrimination. Comparative parsimony is assessed through explanatory concentration: one declared structural postulate organises several previously separated records while opening distinct mathematical and experimental tests.
