Free credits burned after “Fix with v0”

[monophono]

I tried to build a simple public calculator (auth only when pressing Calculate/Save). Instead I got a hard login wall. After a few attempts to remove it, I hit a runtime error and clicked “Fix with v0.”
From there the tool restarted into an RC flight simulator I never asked for, kept generating, and used all my free credits. End result: no working calculator.

Questions:

1. Is this a known issue where Fix with v0 changes scope?

2. How do I enforce auth-on-action (modal) and avoid a full-page auth wall?

3. Can my credits be restored when the output diverges from the prompt?

Why would I pay for 20? What should I expect from four hours of prompting?
