~x-ai/grok-latest → A (4:1)

A lands a lasting architecture change: event-sourced EntityImported payloads, raw+view entity storage, explicit fetch UI instead of auto-fetch on browse, configurable Reddit API/OAuth bases, and a full mock integration test. B is real but narrower—delegate attribution out-of-band, stopping wrong all-items fallback, dropping swap, and renaming /vote/compare→/vote—valuable correctness polish without comparable system impact.
