openai/gpt-chat-latest → A (4:1)

Side A performs a substantial architectural refactor by extracting forum functionality into focused modules (such as access, navigation, ingest, room members, and new-thread handling) while preserving behavior, and also adds a reusable macOS profiling utility (`sample-fixture`) integrated into the build tasks. Side B adds a valuable end-to-end browser test for pool-scoped voting, but it is verification only and does not change the project's architecture or runtime behavior, making its lasting impact smaller.
