Side B is a small, coherent, working change: it improves the dev fixture script to use cargo-watch with a persistent data dir and preferred port, and removes redundant UI markup, all integrated into the actual codebase. Side A is a disorganized dump of stray untracked files (many pasted with shell prompts like 'tommy@Tommys-Laptop...cat file' baked into the diff), placed at repo root rather than proper module paths, indicating this is not a real integrated commit but leftover scratch content of dubious lasting value.
