We propose a geometric model in which the electron is a static topological soliton of vacuum: a closed toroidal configuration whose energy is stored not as circulating electromagnetic flow on the surface, but as a 4π torsion-twisted vacuum core. A variational functional is introduced on a toroidal core region, combining an electromagnetic contribution and an effective torsional stiffness term, subject to a global action quantization constraint. A simple ``thread-linear'' concentration law yields a robust energy partition between compression-dominated (core/mass) and extension-dominated (boundary/charge) regions. This work presents a refined geometric model including bicone extensions and variable surface tension that enhance stability and provide quantitative corrections to the anomalous magnetic moment
