Systematic Debugging
Core Principle
NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST.
Never apply symptom-focused patches that mask underlying problems. Understand WHY something fails before attempting to fix it.
The Four-Phase Framework
Phase 1: Root Cause Investigation
Before touching any code:
- Read error messages thoroughly - Every word matters
- Reproduce the issue consistently - If you can't reproduce it, you can't verify a fix
- Examine recent changes
