~x-ai/grok-latest → A (3:1)

A delivers lasting core architecture: entity JSON moves out of GlobalTree into RocksDB via EntityStore, event log replay streams line-by-line (cutting startup RAM), and apply_entity paths stop retaining full payloads in memory. B is high-value but narrower—fail-closed vote auth, mock-OAuth gating, Secure cookies, return-to hardening, and nav alias—important security/UX fixes that do not reshape the data plane like A.
