Aziz & Howl (Nature 646, 813, 2025) demonstrate that classical theories of grav- ity, when coupled to quantum field theory matter, generate entanglement through virtual matter propagators—a classical-QFT effect parametrised by ϑ ∝G2m2M 3R/(ℏ3d3), where m is the constituent particle mass. In the One-Octonion Brane-Bulk Framework, gravity is a brane current and quantum tunnelling corresponds to transient bulk excursions with prob- ability fbulk = 3.6917%. This provides a third mechanism for gravitational entanglement— bulk communication—distinct from both the Aziz-Howl virtual-matter channel and standard graviton exchange. The framework entanglement parameter is Ebulk ∼fbulk × φ in the near- field regime d < rT ∗ 2 (M) ≡ p GM/a0 (where a0 = 1.042 × 10−10 m s−2), and Ebulk ≈φ in the far-field regime. A fundamental crossover scale dP = p 2πℓPc/H0 = 118 µm separates the regimes at the Planck mass MP. The framework and Aziz-Howl effects are experimentally distinguishable: ϑ depends on constituent particle mass m2 (material-dependent), whereas the framework near-field enhancement depends only on total mass M and separation d through rT ∗ 2 (M) (material-independent).
