I present the complete zero-free-parameter derivation of the CMB scalar spectral index nₛ = 0. 9649 from the Lomas Framework. The derivation chain is: gammaVoid = 1. 0364 (Void superfluid adiabatic index, constrained by bubble stability) => alphaG = 0. 01786 (Guderley self-similar exponent) => delta = 0. 0351 (density profile exponent) => nₛ = 1 - delta = 0. 9649. One input. One output. Zero free parameters in the spectral slope. This matches Planck 2018 (0. 9649 +/- 0. 0044) to four decimal places. The paper includes: ghost-free reformulation of the Paper 1 action using the Gauss-Bonnet invariant and DHOST scalar-tensor theory; first-principles derivation of gammaVoid = 1 + epsilon from the modified FRW field equations; complete ADM Hamiltonian constraint analysis proving 2 physical degrees of freedom with no ghost modes; explicit Dirac algorithm, hypersurface deformation algebra, and DOF counting; grand synthesis across ADM, Ashtekar variables, Loop Quantum Gravity, holography, black hole entropy, and shape dynamics. Additional predictions: tensor-to-scalar ratio r ~ 5 x 10^-3 (null B-mode detection) ; non-Gaussianity fNL ~ +0. 015 (squeezed) ; spectral running alphaₛ ~ +0. 0006. Thirty-two independent hostile referee objections answered across four review rounds.
