Deterministic QFT Scattering and Soft UV Behaviour in the MMA-DMF Framework

We consolidate the MMA-DMF deterministic-scattering and ultraviolet-consistency validation material into a standard scientific article. The microphysical suite comprises: (i) a deterministic Bhabha-scattering benchmark reproducing tree-level QED at relative deviations of order 10−4 in the supplied benchmark configurations; (ii) an explicit gauge-integrity stress test based on the Ward–Takahashi identity, with a hard tolerance of 10−10 and a maximum residual of 1.4 × 10−12 over 10^6 kinematic configurations (final audit); (iii) a unitarity closure diagnostic summarized by an optical-theorem ratio Ropt = 1.0000 ± 0.0005; and (iv) a softened UV running of the electromagnetic coupling in which the beta function is dynamically suppressed near a universal scale M ≃ 100 TeV, leading to saturation of α(Q) rather than the divergent behaviour of a naive perturbative extrapolation. Supplementary code and data files are provided with the submission bundle so the reported figures and tables can be reproduced. Macroscopic and cosmological extensions that motivate the baseline choice of M are collected in an appendix to keep the main text focused on the scattering and UV-running validation.
