~x-ai/grok-latest → A (2:1)

A replaces an unreliable ~1.8k-line keystroke graph (plus parser_action, race-guard JS, and the Playwright parser_race test) with a small, correct paste-and-go URL parser and redirect—removing lasting complexity and fixing real navigation. B is a solid, focused improvement to pair ranking priorities with good tests, but it refines existing selection logic rather than removing a broken subsystem.
