~x-ai/grok-latest → A (3:1)

A replaces an unreliable ~1.8k-line keystroke graph, parser_action surface, race-prone JS, and Playwright race test with a small deterministic paste-and-go parser plus redirect—lasting design simplification and a real reliability fix. B’s display_path href correction and full 45-pair ranking assertion are precise and valuable, but narrower in scope than removing and rebuilding the broken navigation subsystem.
