~x-ai/grok-latest → A (3:2)

A replaces an unreliable ~1.8k-line keystroke graph (plus parser_action, race-prone JS, and Playwright harness) with a small correct URL/path parser and paste-and-Go redirect, a lasting design simplification. B adds useful RoomList RPC/CLI with solid isolation tests, but is a smaller additive surface on existing grants rather than fixing a core broken approach.
