Emergent Tensor Gravity from Vacuum Entanglement Scattering

The Vacuum Folding Dynamics (VFD) framework models gravity through a scalar field σf representing the vacuum micro-state density. Paper A established a Le Sage overpressure mechanism in which isotropic vacuum flux, partially attenuated by matter, reproduces Newton's constant through a self-consistency condition. That derivation assumes the full-gravity interpretation but does not derive the spin-2 (tensor) sector that carries ~99. 9999999% of the gravitational interaction. This paper closes that gap. We show that the VFD entanglement entropy sₕol = kB c₀ (σf/σ₀) ^2/3 / lP² (Paper VII) provides the area-scaling input required by the Jacobson (1995) thermodynamic construction. Applying the Clausius relation δQ = TU dS to local Rindler horizons, combined with the Raychaudhuri equation as a geometric bridge, yields the full Einstein equation G⏛⏜ + Λ g⏛⏜ = (8π GN / c⁴) T⏛⏜ — including the complete tensor structure — with an effective gravitational constant Gₑff = GN / (4 c₀). Consistency between the Le Sage route (Paper A, constraining the scalar mass m_σ) and the Jacobson route (constraining the boundary-mode fraction c₀) requires c₀ = 1/4, yielding Gₑff = GN exactly. In the Le Sage overpressure picture, the scalar field satisfies δσf/σ₀ < 10^-260 everywhere, so Gₑff = GN universally — not only in the weak-field limit. The Susskind-Uglum (SU) mechanism is extended to VFD's Brans-Dicke action at the equilibrium point Φ₀ = 1, providing independent UV support for c₀ = 1/4 at Level 3. The scalar-only interpretation — in which the Le Sage mechanism generates only α² GN — destroys the constant product α · λC = 3. 59 μm, leaves the tensor sector unexplained, and eliminates VFD's main experimental signature. An exponent error in Paper A §8. 1 is corrected. Eight open problems are catalogued. The paper rests on two assumptions beyond established physics: (1) the VFD micro-state Hilbert space (Paper VII), and (2) the Clausius relation on local Rindler horizons (Jacobson 1995).
