Numerical Validation of CETΩ Perturbation Dynamics with CLASS

This dataset provides the numerical validation material associated with the CETΩ perturbation analysis discussed in the accompanying paper. It includes modified CLASS source code, minimal input parameter files, non-linear matter power spectra, and scripts used to verify the stability and magnitude of the CETΩ corrections to structure growth. The figures and data provided here are intended for independent validation and are not direct reproductions of figures appearing in the published manuscript.
