I will base44 app fixing base44 bug fixing base44 app security fix cors rate limiting

Base44 apps break in the same places. A backend function fails and the page spins. Users can read data that isn't theirs. An outside API call dies with a CORS error. A public form gets spammed. My Base44 debugging starts at the root cause, not the symptom, and every order ends with a short report of what changed.
