~x-ai/grok-latest → B (2:3)

B replaces a stub with a real Reddit fetch path (background broker, OAuth, rate-limit/backoff, URL mapping, JSON parsing, and wiring into browse/ensure_path), which is lasting product capability. A is solid, tested offline DSL/JSONL tooling, but it is workspace/dev-only support rather than core runtime behavior; B’s impact outweighs A’s polish despite A’s cleaner docs.
