Fix Root Causes
Trigger
During debugging and incident repair.
Rule
Reproduce the symptom, trace causality until one mechanism explains it, and fix that mechanism rather than compensating for downstream effects.
Application
- Name the concrete decision this principle changes.
- Apply the rule to that decision, not as a decorative citation.
- Prefer evidence from the current repository/runtime over generic preference.
- If the principle conflicts with an explicit user constraint, keep the constraint and state the tradeoff.
