This Zenodo repository contains the supplementary material accompanying the manuscript "Secular Drift of the UAT Scalar Field and Cosmological Imprints: From the Causal Membrane to the Genesis Factor" by Miguel Angel Percudani. Contents: Manuscript source code (LaTeX) with all figures. Python code implementing the modified Friedmann equation with the secular drift correction, Om(z) diagnostic, and chi-squared analysis against cosmic chronometer data. Full table of 31 cosmic chronometer H(z) measurements (Moresco et al. 2016, 2020) used in the analysis. Technical notes on limitations of the UAT/UCP validation program (data corruption, LIGO design constraints, Boltzmann code implementation barriers).

The cosmic chronometer data are provided as a separate LaTeX file for transparency. Abstract of the manuscript: We formalise the "Genesis Factor" as a secular perturbation of the UAT scalar field, derive its correction to the Friedmann equation, and constrain its amplitude and exponent with 31 cosmic chronometer measurements. We find a 95% upper limit |beta| < 0.25 and a mild preference for beta ≈ 0.08, gamma ≈ 0.12. We project the sensitivity of future surveys (Euclid, Roman) and propose a dedicated laboratory experiment (UAT Phase Clock) to detect the secular drift of the scalar field directly.
