Systematic Debugging

Overview

Guessing fixes wastes time and creates new bugs. Quick patches hide root problems.

Core principle: Never fix before finding the root cause. Symptom fixing is failure.

Iron Law

Never propose a fix without root cause investigation.

Phase 0 or Phase 1 must be completed before any fix is proposed. Phase 0 fixes are ONLY allowed when ALL of these are true:

• External research found an official solution or known issue for this exact error
• Change is single file, single point (config value, import, typo)
• No logic changes
