~x-ai/grok-latest → A (4:1)

A delivers a complete, production-shaped Reddit import path (background broker, OAuth, rate-limit/backoff/dedup, JSON parsers, UI trigger, and wiring into AppState) that adds real external capability. B is a worthwhile type-hygiene refactor (Deref on URL newtypes and threading CanonicalItemUrl through resolve_item/pair/rank helpers) but only removes string churn with no new behavior.
