C-Series Cross-Validation & Likelihood Report: Empirical Tests of Void Weak-Lensing Suppression under the U4DTST Model

This dataset accompanies the publication “Empirical Evidence for Void Weak-Lensing Suppression Consistent with U4DTST” and contains all materials required to reproduce the C-Series covariance-aware cross-validation analysis. The study tests the key prediction of the Unified 4D Topological Substrate Theory (U4DTST) that regions of negative substrate twist manifest as a measurable anti-lensing (suppression) of gravitational convergence in cosmic voids.Using stacked void profiles with full jackknife covariance, ridge-shrinkage conditioning, and bootstrap resampling, the analysis finds a suppression amplitude s^=−0.0168±0.00033,\hat{s} = -0.0168 \pm 0.00033,s^=−0.0168±0.00033, corresponding to a ~1–2 % reduction in convergence (Δκ ≈ 10⁻³) relative to ΛCDM.The signal is numerically robust and physically interpretable as evidence consistent with the predicted anti-lensing behaviour of U4DTST’s negative-twist phase. All figures, tables, notebooks, and CSV/JSON data are openly released for independent replication and comparison with upcoming surveys (DES Y3, KiDS-1000, Euclid, DESI).
