Abstract

Singh, Rønning, Liu, Angheluta, Concha focal zones (mass = standing-wave nodes in the brane current, Paper I) form within these vortices; the winding number n determines the quantum numbers of the focal zone. The AB fluid analog parameter at the Planck length λ = ℓP gives αbrane = h/ħ = 2π, so for winding n the nodal count is 2πn = 6n. For n = 1: six ⌊ ⌋ nodal lines — exactly the six short roots of G₂. For n = 2: twelve nodal lines — the full G₂ root system (6 short + 6 long). This is not a numerical coincidence: the G₂ root system IS the nodal structure of the brane standing wave around a unit-winding vortex at the Planck scale. We further identify: (1) charge = nodal count (integer winding number projection) ; (2) spin = nodal line orientation (fractional α = half-integer spinor structure) ; (3) the non-local, reservoir-spanning nodal pattern as the classical analog of the brane thread entanglement (Paper XV) ; and (4) the time-oscillating nodal lines as the classical analog of T2* dephasing of the focal zone (Paper XII). Three predictions follow, with honest identification of which are derived and which are qualitative. Part of the One-Octonion Brane-Bulk Framework series. Anchor DOI: 10. 5281/zenodo. 19120873.
