✓ 应当这么做
- ✓ Classify failures once: expected (validation, not-found) vs unexpected (bugs, dependencies down)
- ✓ Return typed errors carrying a stable code plus human-readable context
- ✓ Map errors to user-visible outcomes at the outermost layer only
✕ 常见反模式
- ✕ String matching on error messages to decide control flow
- ✕ Swallowing an error to keep the happy path green
- ✕ Leaking stack traces or internal identifiers to end users
◎ 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
