B-mode null tests for UNIONS-3500 cosmic shear pass after galaxy size cuts and stellar masking, with an oscillatory pattern from additive shear bias suppressed by excluding CCD angular scales.
Cross-covariances and cross-correlations between Euclid spectroscopic and photometric probes have negligible impact on cosmological parameter constraints.
