openai/gpt-chat-latest → A (4:1)

Side A implements a substantial new capability: an end-to-end invite system with invite minting, redemption during OAuth, room auditing, new RPCs/CLI commands, server routes, state management, and integration tests covering the workflow. Side B improves DSL parsing and HTML linkification by adding deterministic block masking, prose reference tokenization, URL handling, stricter braced item bodies, and tests, but these are narrower parser/UI enhancements compared with the lasting project functionality introduced in Side A.
