| contents | <p>This record presents the empirical validation of the <em>Sigma–Schmidt Duality</em> as a cosmological model tested against full DESI DR2 BAO data.<br>The analysis includes χ² comparisons, parameter scanning and robustness checks, showing that the two-parameter σ(t) deformation provides a significantly improved fit relative to ΛCDM.<br>The PDF contains methodology, data handling, residual analysis and full reproducibility notes.<br>This upload is part of an ongoing research series developing the dual scalar-field interpretation of cosmic expansion and its observational signatures.</p> |
