~x-ai/grok-latest → B (2:3)

B redesigns the project’s core user-facing DSL (explanation-first votes, stricter block placement) with real parser/API/UI changes and coordinated fixture updates, so it shapes how content is authored going forward. A is a solid, necessary Reddit OAuth reliability fix (no public API fallback when creds exist, 401/403 refresh, error truncation) plus a fly.toml pin, but it is narrower infrastructure glue rather than lasting product surface.
