Motti Intermediate Physics: Derivation of the Fine-Structure Constant from a Single Consistency Postulate, a No-Go Theorem for Coherential Interactions in Condensed Matter, and the Computational Programme for Dynamical Gap Closure

The electromagnetic fine-structure constant alpha_em = 1/137.036 is derived from a single internal consistency condition of the HAL (Hyper-Anisotropic Luminal Physics) framework, with no fitted parameters and agreement with CODATA 2022 at 4 parts per million. The derivation proceeds through an exact algebraic chain fixing the quartic coupling lambda = 8*pi/9, the instanton action S_inst = 3*pi, the functional determinant Tr[D*V''] = 6 (Watson 1944), and the renormalization coefficient beta_RG = 2/pi. The quantization integer n=27 is shown to be unique: it is the product of the SO(4) degeneracy of the l=2 instanton level (d=9) and the internal Z_3 multiplicity of the complex coherential field (dim=3). From the same postulates, G_eff = G_N/C_0 and a universal gravitational spin-memory correction epsilon = +alpha_em = +0.7297% are derived exactly. The prediction is universal, positive, and falsifiable with LIGO O5, LISA and the Einstein Telescope. A rigorous no-go theorem establishes that the dark sector of HAL cannot produce Cooper pairing in any condensed matter system. Exact path integration over dark sector modes yields a ghost mediator with Planck-scale pole (k_polo = 0.958 M_Planck) and negative residue (Z_D = -0.00657), generating a repulsive effective interaction suppressed by 10^-24 eV at material scales. Unitarity is preserved by the Lee-Wick mechanism; macroscopic causality is preserved by Yukawa decay at sub-Planckian scales. The dark sector acts as a natural UV regulator that decouples universally from sub-Planckian physics. The dynamical confirmation of J_total = C_0^2 * J_GR remains an open problem. A concrete three-stage computational programme is proposed: effective one-body (EOB) methods for the inspiral, numerical relativity (BSSN/Z4c) for the merger, and an extended Teukolsky equation coupling gravitational perturbations to the coherential Xi operator for the ringdown. All three stages converge on the same observable: the gravitational spin-memory effect at epsilon = +0.7297%.
