Side B is a genuine structural refactor extracting forum.rs logic into focused submodules (nav, ingest, new_thread, room_members, access) with clear separation of concerns, improving long-term maintainability. Side A is a dev-tooling improvement (persistent fixture data, cargo-watch) that's useful but more ephemeral/local-workflow-focused, and even includes an unrelated regression removing room title/breadcrumb markup from forum.rs without explanation.
