✓ 应当这么做
- ✓ Split every breaking change into expand, migrate and contract phases
- ✓ Make the migration idempotent so a re-run is a no-op
- ✓ Rehearse on a production-shaped copy and record the rollback path
✕ 常见反模式
- ✕ Irreversible destructive steps in the same release as code removal
- ✕ Big-bang cutovers with no parallel running period
- ✕ Migrations that depend on manual console steps
◎ 交付前验证
- ◎ Type checker (mypy/pyright) passes with zero new suppressions
- ◎ Tests run in a clean virtual environment
- ◎ No secrets or environment values read at import time
