~x-ai/grok-latest → A (2:1)

A replaces an unreliable ~1.8k-line keystroke graph, ParserAction surface, racey JS, and Playwright race test with a small paste-and-go URL parser and redirect—removing failed complexity and leaving a durable navigation path. B meaningfully speeds scan (parse-only, no full replay), surfaces full parse_error detail, and adds compile --ingest, but those are incremental offline-tooling fixes versus A’s structural product/design simplification.
