~x-ai/grok-latest → A (3:1)

A adds lasting core runtime and ops pieces (EventLog JSONL append/load, ViewStore with async flush, multi-stage Dockerfile, fly.toml mounts/health checks), which the product and deploy path depend on. B improves local DX (cargo-watch fixture, persistent fixture-data/, prefer-8080) plus a small forum HTML trim—useful iteration polish, but not comparable foundational design.
