~x-ai/grok-latest → A (3:2)

A removes an ~1.8k-line unreliable keystroke graph (parser, parser_action, race JS/CSS/Playwright) and replaces it with a small correct paste-and-go URL parser plus redirect, permanently cutting flaky surface area. B is a precise, high-value RwLock-scope deadlock fix in RoomCreate/RoomGrant with a regression test and test-harness hardening, but its lasting impact is narrower than A’s subsystem replacement.
