openai/gpt-chat-latest → B (3:2)

Side B delivers a substantial architectural change by consolidating many REST endpoints into a typed RPC batch API, refactoring shared validation into a dedicated module, introducing room-scoped operations, and updating the CLI, server, event model, and tests to match. Side A adds valuable deployment infrastructure, a live audit dashboard, SSE progress reporting, and operational improvements, but much of its impact is in observability and deployment rather than the project's core API and data model.
