✓ 应当这么做
- ✓ Annotate every public function and validate boundary data with the project schema layer
- ✓ Use built-in generics (`list[str]`, `dict[str, int]`) on modern targets
- ✓ Keep I/O async all the way or sync all the way inside one module — never mixed implicitly
✕ 常见反模式
- ✕ Bare `except:` blocks or catching Exception without re-raising context
- ✕ Mutable default arguments
- ✕ Untyped dictionaries passed between layers as an implicit protocol
◎ 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
