- statistics.jackknife_weighted_mean: delete-one-patch jackknife of a weighted mean. - survey.additive_bias_errors: shape-noise error sqrt(sum w^2 (e-c)^2)/sum w and the patch jackknife error of c1, c2. - CosmologyValidation.calculate_additive_bias_errors: jackknife over the seeded k-means patches of the 2PCF, so the error includes spatially correlated contributions (cosmic shear, PSF residuals); print_additive_bias writes c with both errors (txt) and with jackknife errors in units of 1e-4 (tex). - _read_shear_cols: column name 'one' gives unit weights (w_col: one).

CosmologyValidation reads a star section for every version; the three uncalibrated v1.4.6.3 entries (DES, inverse-variance and unit weights) had none and failed with KeyError 'star'. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
