The observed universe contains virtually no primordial antimatter, yet the Standard Model cannot quantitatively explain the baryon asymmetry. This paper proposes a novel mechanism within the H-SET framework: during the spatial condensation phase of the extremely early universe, equal numbers of vortex rings and anti-vortex rings are produced, but the fixed helicity selectivity of the chiral torsion field causes the decay rate of anti-vortex rings to be far higher than that of their matter counterparts. Based on the Basal Elastic Mass Invariance Theorem and a chiral asymmetry parameter constrained by the lepton mass spectrum, we derive the asymmetric decay dynamics. After production ceases, anti-vortex rings decay back into diffuse space on a timescale far shorter than the Hubble time, while vortex rings remain stable, becoming the source of all matter in the observable universe. The final baryon-to-photon ratio naturally reaches the order of ten to the minus ten, consistent with observations, without introducing new physics beyond the established H-SET axioms.
