✓ 应当这么做
- ✓ Reproduce with the smallest input that still fails
- ✓ Bisect by evidence: logs, traces, and a single hypothesis per step
- ✓ Write the regression test before fixing the cause
✕ 常见反模式
- ✕ Changing several things at once to "see if it helps"
- ✕ Closing an issue on a flaky repro without a test
- ✕ Silencing the symptom instead of removing the cause
◎ 交付前验证
- ◎ EXPLAIN on the hot queries shows no sequential scan regression
- ◎ Migration rehearsed on a production-size snapshot
- ◎ Rollback path executed at least once in staging
