This paper develops an ab-initio electroweak normalization in which the SU(2)L and U(1)Z gauge couplings—and therefore the electromagnetic coupling e and fine-structure constant α—are fixed by a coherent pre-geometric background rather than calibrated to Standard Model electroweak data. A single background stiffness τ(ρ0), together with fixed projection weights selecting the weak and Cartan directions, defines the neutral kinetic structure. The photon arises as the unique massless neutral mode, and its coupling is extracted without introducing electroweak fit inputs. Using these UV “boxed” boundary conditions at the coherence/matching scale Λq, we evolve the couplings to MZ (and to the Thomson limit) with a two-loop EFT renormalization group including threshold matching and quantified internal theory bands. For the canonical product-UV (isotropic) ledger (ωL,ωZ)=(1,1) with τ(ρ0)≈0.178, the baseline prediction is α−1(MZ)≈140.8 and sin2θW(MZ)≈0.258, which motivates a refinement: the realized coherent vacuum cannot be isotropic. A diagnostic inversion identifies the required deformation of the neutral stiffness kernel, and Appendix J exhibits a concrete microscopic mechanism—coherent coupled dynamics of the morton x-pair—that naturally generates the needed anisotropy and yields UV handles consistent with the observed electroweak normalization α−1(MZ)≈127, sin2θW(MZ)≈0.231 in the Scenario-B closure. The paper also includes a first-principles lattice computation of vacuum polarization in an internal S[θ,Z] current theory (a controlled analogue used for internal consistency/closure, not a claim of full QCD reproduction). Code, run manifests, and data products used to generate figures and tables are provided in the accompanying repository. Revision note: This update completes the scale-closure program introduced in Appendices J.10 and J.11. The coherent ((x))-pair coordinate convention, kernel/Hessian normalization, and microscopic source construction have been audited against a common scalar-filtered parent solution and implemented in a dedicated numerical closure pipeline. Appendix J.11 now provides an explicit parent-derived closure of the reduced scale equation. The Schur-reduced kernel, source vector, scalar-wall sector, and twist-fluctuation determinant are exported from the same microscopic parent configuration and combined into a single variational scale equation. A numerical audit demonstrates a stable finite stationary solution with positive-definite reduced kernel, finite coherent coordinates, and positive second variation, establishing internal consistency of the scale-selection mechanism without electroweak matching, Planck-scale anchoring, Newtonian calibration, Standard Model mass inputs, or other external normalization prescriptions. The source normalization used in the closure analysis is shown to be consistent with the Morton Projection Theorem of Appendix K in Ref.~[7]. In particular, the coherent branch requires removal of the sixfold photon-level amplification associated with the composite-photon measurement geometry, yielding a source normalization appropriate to a single coherent morton branch. This relation is derived from the existing projection framework and is not introduced as an independent fit parameter. No changes were made to the derived electroweak observables, renormalization-group evolution, benchmark closure results, uncertainty estimates, numerical predictions, or phenomenological conclusions. The update affects only the microscopic displacement-scale closure and provides an explicit parent-derived realization of the scale-selection mechanism previously presented in formal form.
