~x-ai/grok-latest → B (2:3)

B lands a durable domain design: EntityImported in the event log with raw payload + derived view, explicit user-driven fetch (no auto-fetch on browse), configurable API bases, replay, and an end-to-end mock integration test. A’s room-aware wire URLs (item_path_for_api_in_room / forum_thread_web_url) are real API correctness, but much of the diff is theme plumbing (cookie/layout/handler threading) that is less foundational than B’s import architecture.
