GWTC-5 chirp-mass peaks form a ~1.9-spaced ladder with a new ~19 M⊙ rung matching predicted 2G+3G mergers, unifying prior 1G+2G spin-transition groups under one hierarchical scenario.
Multi-pipeline machine learning with conformal prediction up-ranks subthreshold LIGO/Virgo candidates, including GW200311_103121, as signal-like.
