Reports full-covariance Omega_m sensitivity in the Pantheon+ supernovae sample, indicating consistency in results.
MNRAS submission MN-26-1198-P. Resubmission successor to MN-26-0967-P. Reports the full-covariance Omega_m sensitivity of the Pantheon+ Hubble-flow sample (0.023 <= z <= 0.15, N=492), with full Cstat+sys covariance, M floated as a free parameter, and a null-test-validated null result. Methodology deltas from the precursor MN-26-0967-P: redshift selection (cosmology-independent Hubble-flow gate), covariance (full Cstat+sys), and M-floating. Submitted 2026-04-25 to MNRAS.
