Correction Notice: SHR-R2 Reanalysis of "Substrate-Higgs Coupling at 125 GeV"

This correction notice documents SHR-R2, an expanded reanalysis of the collider phenomenology reported in Taneja (2025), "Substrate-Higgs Coupling at 125 GeV: Universal Compression Resonance in CMS and ATLAS Dijet Data" (DOI: 10.5281/zenodo.17755514). SHR-R2 reprocesses the full ATLAS 13 TeV 2bjets70 open-data sample across 16 data-taking periods using finer 10 GeV H_T binning, multiple jet-pT thresholds, an eligible-dijet denominator, untruncated beta distributions, and period-resolved stability tests. The reanalysis does not reproduce two quantitative predictions stated in Section 5.1 of the original paper: a peak fixed at H_T approximately 125 GeV and beta convergence to 0.137 +/- 0.01. Under the original paper's stated falsifiability criterion, these results falsify the substrate-compression hypothesis as formulated and tested in that specific collider implementation. SHR-R2 nevertheless finds a broad and reproducible H_T-dependent selected-dijet topology structure. Its characteristic location varies with jet-pT threshold and data-taking period and is therefore not interpreted as a replacement universal physical scale. The attempted matched Standard Model QCD Monte Carlo comparison is classified UNSCOREABLE because the available weighted MC has inadequate effective statistics for a reliable quantitative null test. The correction applies to the specific collider formulation and observable mapping advanced in the 2025 paper. It does not constitute a falsification of the broader Space-Gravity research programme. The notice also clarifies that the experimentally measured Higgs-boson mass near 125 GeV is derived from reconstructed invariant-mass observables rather than from a generic dijet H_T sum.
