Version 2 (2026-07-03): corrections only, no change to the physics — fbulk 3. 6917%%→3. 6919%%; mass-unit labels ("10 µg"→"10 mg" in §4. 3; figure ng→µg). Equations (9) – (11) unchanged and verified correct. 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).
