~x-ai/grok-latest → B (1:7)

B is a lasting architectural pass: it consolidates the scattered REST surface into a batched RPC API, splits permission boundaries into rooms vs forum threads in events/reducer state, and updates CLI plus tests accordingly. A only adds seed/deploy scaffolding (Dockerfile, fly.toml, deps.edn) plus small standalone modules (event_log, views), which is useful plumbing but not core product design.
