~x-ai/grok-latest → A (2:1)

A’s lasting value is architectural: entity JSON moves out of in-memory GlobalTree into a RocksDB-backed EntityStore, and event_log gains true line-at-a-time replay so startup no longer materializes the full log/payloads in RAM—concrete reducer/state/reddit call-site changes that change scalability. B is real product/ops work (Fly/Dockerfile/CI deploy, /watch audit SSE, production repo/contributor roots, emission retry), but it is mostly deployment, UI, and configuration on an existing process rather than a deeper data-plane redesign.
