# Debug With Goal 1. Read full error, stack trace, logs, file paths, and line numbers. 2. Reproduce consistently when possible. 3. Check recent changes with git diff/log. 4. Find similar working code. 5. Trace bad value or failing state backward to source. 6. State: `Root cause is X because Y`. 7. Make smallest fix that addresses root cause. 8. Verify with tests or a direct repro. After 3 failed fixes, stop and reassess architecture. Do not stack speculative fixes.
