Today's roundup leans heavy on artificial intelligence, from quiet quality throttling in coding assistants to labs that still can't say how they'd contain a rogue model. Elsewhere, developer productivity essays, fintech and payments moves, a US-Canada trade collapse, and a few sobering climate stories round things out.
