Addendum: Observational Tests for the Residual Momentum Framework (Dark Energy)

This addendum provides a comprehensive examination of observational tests designed to validate or falsify the Residual Momentum Framework, an alternative to ΛCDM that explains cosmic acceleration without invoking Dark Energy. The analysis focuses on comparing observational data with theoretical predictions, particularly the evolution of the Hubble parameter H(z), redshift drift, and large-scale structure formation.
