principle-fix-root-causes
GitHub用于调试场景，要求追踪症状至根本原因并修复，而非添加掩盖问题的临时措施。强调先复现、追问根因、检查状态及模式匹配，避免使用空值检查等防御性编程手段。
Trigger Scenarios
需要调试代码或系统问题
遇到反复出现的错误或崩溃

Fix Root Causes
When debugging, do not paper over symptoms. Trace every problem to its root cause and fix it there.
Why: Symptom fixes accumulate. Each workaround makes the system harder to reason about, and the real bug remains. Root-cause fixes are slower upfront but reduce total debugging time.
Pattern:
- Reproduce first (if you can't reproduce it, you can't verify your fix)
- Ask "why" until you hit the root cause
- Resist the urge to add guards (adding a nil check to silence a crash is a symptom fix)
- Check for the pattern, not just the instance (grep for the same pattern, fix all instances)
- When stuck, instrument. Don't guess (add logging, read the actual error)
Restart bugs: suspect state before code
Code doesn't change between runs. State does. When something "fails after restart," suspect stale persistent state first: config files, caches, lock files, serialized state. If clearing a state file restores behavior, prioritize state validation as the fix.
