openai/gpt-5.2-chat → B (3:2)

Side B performs a major structural refactor of the server HTML layer: it removes a 1400+ line monolithic forum.rs file and replaces it with a properly modularized forum/ directory (feed, views, paginator, profile, thread_morph, etc.), resolving module ambiguity and significantly improving maintainability and architecture. This is a deep internal reorganization affecting many routes and UI behaviors. Side A is also substantial—reshaping the CLI command hierarchy, updating docs, tests, and RPC hints—but it is primarily a surface/API restructuring. The architectural impact and long-term maintainability gains in Side B are greater overall.
