openai/gpt-chat-latest → B (3:2)

Side B makes a focused architectural improvement by introducing a shared `thread_xml` formatter used by both the CLI and browser copy path, eliminating duplicated formatting logic while also extending the RPC `ThreadItem::Post` with `delegate` metadata and adding tests for XML escaping and output. Side A adds a large new `adam.py` tool and deployment documentation/scripts, but much of the patch is new application code and operational guidance rather than an improvement to existing project structure, making B's reusable refactor and API enhancement the more durable contribution.
