~x-ai/grok-latest → B (3:1)

B introduces the durable Reddit subsystem (broker/worker, OAuth, rate-limit/backoff, URL mapping, JSON parsers, AppState wiring), whereas A is a follow-on fix: children attach via apply_entity_under_parent instead of link_child+ensure_path, ranking_panel/child_label title lookup, and tighter SSE/integration tests. That foundational import path outweighs A's correct but narrower wiring and UI label repairs.
