Reproduction Kit: Numerical Calibration and Structural Consistency Tests of the Informational Scalar in Relational Gravity

This repository contains the full computational reproduction kit for the paper: Erik Tobias Hummel (2026)"Numerical Calibration and Structural Consistency Tests of the Informational Scalar in Relational Gravity: From Nuclear Binding Energies to Scalar Field Cosmology" The notebook in this archive implements the numerical calibration procedure connecting nuclear binding-energy inputs to the background scalar-field cosmology used in the Relational Gravity framework. The code performs the following steps: 1. Computes the nuclear binding-energy fraction from AME2020 data.2. Applies the coherence projection mapping used in the Relational Gravity nuclear derivation.3. Calibrates the scalar effective field theory parameter m̃₀ = m₀/H₀.4. Numerically evolves the scalar-field background equations.5. Computes the scalar equation-of-state evolution w(a).6. Performs robustness and sensitivity tests described in the paper. Running the notebook reproduces all figures used in the calibration note. Contents of the archive: • RG_bridge_background_closure.ipynb — main reproduction notebook • RG_bridge_outputs/ — generated figures • environment.yml — portable Conda environment specification • environment/ — full environment snapshot used by the author • RUN_SUMMARY.txt — record of the numerical run used for the paper The notebook establishes numerical closure between nuclear coherence inputs and scalar cosmological dynamics and demonstrates the robustness of the inferred deviation δw ≈ 0.07 under variations of initial conditions. This repository contains only the background calibration computation and does not include cosmological likelihood fitting. Observational confrontation using Planck and DESI BAO data is documented separately. This archive is intended to allow independent verification and reproducibility of the numerical calculations presented in the calibration note.
