~x-ai/grok-latest → A (2:1)

A removes an unreliable ~1.8k-line keystroke transition graph, ParserAction surface, race-prone JS debounce path, and Playwright race test, replacing them with a small deterministic URL→subreddit parser and paste-and-Go redirect that actually ships navigation. B is a real, well-tested domain fix (reject 0:* / *:0 and >100 ratios in DSL, UI handler, and reducer) but is a narrow constraint layer versus A’s lasting simplification of a broken subsystem.
