Debug

A systematic approach to finding and fixing bugs. Stop guessing, start isolating.

STOP: Before You Touch Anything

Before making ANY code change, answer these questions:

1. What's your hypothesis? (Not "I'll try X" but "I believe X is causing Y because Z")
2. What evidence supports this hypothesis?
3. How will you test it? (What result confirms or disproves it?)

If you can't answer these, you're about to debug by mutation. STOP.
