| description | Dùng khi gặp bug, test failure, hoặc unexpected behavior — LUÔN tìm root cause trước khi fix |
ALWAYS find root cause before attempting fixes. Symptom fixes are failure.
NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST
Chưa hoàn thành Phase 1 → không được propose fix
Mọi technical issue: test failures, production bugs, unexpected behavior, performance problems, build failures.
ĐẶC BIỆT khi:
| Excuse | Reality |
|---|---|
| "Bug đơn giản, nhìn là biết" | Nhìn = guess. Root cause mới là truth |
| "Không có thời gian, fix đại đi" | Fix đại = 3 lần thời gian sau này debug lại |
| "Log là đủ, không cần reproduction" | Không reproduce → không biết fix đúng |
| "Fix 1 dòng, không cần typecheck" | Typecheck catch 70% bugs |
