Paper CLXIX: Muon g-2 from Dirac Comb Sampling of Brane-Bulk-Brane Pion Transit (v2: post-Nature 2026 BMW hybrid lattice confirmation addendum)

Sorci et al. (PRL 136, 163602, 2026) demonstrate that ion clock frequencies shift by Δν/ν = −Iω/(4mc2) even in the motional ground state — a vacuum-induced proper-time shift (vSODS). We show that fbulk = 3.691% appears explicitly in Sorci et al.'s formulas at four levels, with the fundamental Planck proper-time uncertainty being 1/4 (pure dimensional counting: 1 time of 4 spacetime dimensions). The hadronic projection 5% → 3.691% proceeds via the hyperbolic G2 permutohedron Laplacian. The muon g−2 WP20→WP25 theory gap of 223×10-11 follows as a zero-free-parameter consequence, with the ππ-channel covering 83.9%. Addendum v2 (§4): Boccaletti et al. (arXiv:2407.10913 v2; Nature, 22 April 2026) report the BMW hybrid lattice result aμ LO-HVP = 715.1 ± 3.4 × 10-10, yielding an R-ratio→lattice shift of +220×10-11 — in 1.4% agreement with the framework prediction. The 4.3σ intermediate-distance-window tension and the CMD-3 (1.3σ) vs. KLOE (6.2σ) channel-resolved pattern confirm the ππ-channel locus of the gap as predicted in §1. Zero free parameters.
