~anthropic/claude-sonnet-latest → A (6:4)

Side A introduces a clean, well-tested, reusable form_template/ui_action abstraction (with substitution unit tests) and refactors web_post handlers into shared run_* functions cleanly used by both /post and /ui, reducing duplication. Side B does deliver real functional room/auth features but also includes an unrelated speculative AI-chat 'plan2.md' document (pure noise) and duplicates large chunks of forum.rs logic across public/room variants without much abstraction, making it noisier and less maintainable despite being larger.
