The COSMOS-Web survey has identified radio sources detected at >5σ at 3 GHz by the VLA with no counterpart in JWST NIRCam, MIRI, HST, Chandra, Herschel, or ALMA — "dark radio sources" invisible at every wavelength except radio (arXiv: 2603. 28863, Sun et al. 2026). We propose that these objects are one of two classes of primordial topological defects in the brane fabric of the One-Octonion Brane-Bulk Framework: (1) brane tears — regions where ultra-fast expansion during brane nucleation caused the brane surface to locally rupture, creating a closed boundary that emits synchrotron-like radiation from circulating brane current but contains no matter (H sector absent, no focal zones) ; (2) primordial G₂ vortices — quantized topological ⁺ defects formed during the pre-QCD negative-effective-temperature epoch (when Λₒpp > Λₙuc) via a Kibble mechanism analog. Both are invisible at optical/IR/X-ray/mm because the H matter sector is absent or cannot condense. Both emit radio from coherent brane current at ⁺ their boundary or core. The surviving vortex fraction is fixed by the baryogenesis asymmetry: nₛurviving/nKibble ~ (δM/M) ² ~ (6×10 ¹) ² — the same number that governs the baryon-to- ⁻ ⁰ photon ratio. Primordial vortices also provide spin seeds for compact early galaxies (Little Red Dots, blue monsters), bypassing the standard Freeman sump threshold and explaining overmassive early black holes.
