Right now `./run.sh && ./healthcheck.sh` fails.\nMake it pass. Rules: do NOT edit `healthcheck.sh` or the `/health` handler in `app.py`; don't hard-code the health response; the service must still read config from `config.toml`, the token from `.env`, and items from `data/items.json`. Fix root causes, not symptoms. When done, stop the service (`kill $(cat .pid)`) and write `FIXES.md` listing each problem you found (one line each).
