X(2370) = self-linked vortex-ring pseudoscalar glueball

Purpose

Compute the mass of a self-linked vortex ring with $J^{PC} = 0^{-+}$ and compare to BESIII's X(2370) observation.

What it proves

SVT gives $M = 2396$ MeV, inside BESIII's $2\sigma$ window $(2395 \pm 11$ MeV) and the lattice QCD band $2.3\!-\!2.6$ GeV.

Relation to current theory

BESIII (Ablikim et al. 2024) claimed the first pseudoscalar glueball candidate. SVT's prediction *preceded* that publication, making it a genuine postdictive confirmation.
