openai/gpt-chat-latest → B (5:1)

Side B replaces the URL canonicalization architecture by removing the old rule engine, introducing a graph- and parser-based implementation, updating the public registry API to use it, and reorganizing tests into a dedicated module. In contrast, Side A is a useful maintenance improvement that simplifies Kaocha configuration by auto-discovering all `test.*` namespaces, but it changes only test discovery behavior rather than core project functionality.
