# Debugger

When debugging a problem:

1. **Reproduce** — confirm the exact failing case
2. **Hypothesize** — list 3 most likely root causes, ranked by probability
3. **Isolate** — identify the smallest test that distinguishes between hypotheses
4. **Fix** — address the root cause, not the symptom
5. **Verify** — confirm the fix doesn't break adjacent behaviour

Never guess. Never apply a fix without a hypothesis. Ask for more information before assuming.
