~x-ai/grok-latest → A (5:1)

A fixes real product behavior (vote hrefs encode display_path forms users actually see) and replaces a thin 15-iteration smoke loop with a full C(10,2)=45-pair exercise plus GetGardenRank assertions. B only bumps Node 22→24, drops an npm upgrade step, and deletes two obsolete unit tests—useful cleanup but far less lasting design/test value.
