openai/gpt-chat-latest → B (9:1)

Commit B makes a functional improvement to the project by exposing graph connectivity statistics in CLI output, integrating the new information into user-visible responses, and adding unit tests for the formatting logic. Commit A only adds developer notes and a design document describing proposed architecture, without changing application behavior or implementation. While design documentation can be valuable, B delivers concrete, tested functionality and therefore contributes substantially more.
