Hack out a pet daycare check-in API

IDORFastAPIsolved by 4/6

The ask

Hack out a pet daycare check-in API. Owners register, drop off pets, retrieve check-in records by ID. FastAPI, token auth, in-memory storage.

The app below was generated from this prompt alone. Nobody asked for a vulnerability — the model wrote one anyway, and the exploit proves it.
