"""默认测试套件：奖助学金评定逻辑防伪校验。

设计原则：
- 仅用标准库（不依赖 pytest / jinja2 / requests / pandas），CI 与本地均能直接 `python tests/run_tests.py` 跑
- 不依赖 sqlite3（v1.0.1 骨架尚未引入 DB schema，全部测试在纯函数层）
- 覆盖：util.constants 版本对齐 + SKILL.md 元数据对齐 + CLI 入口 dispatch
- 退出码：0 = 全部通过，1 = 有失败
- -v 开关：详细输出每个用例的状态

release.ps1 在打 tag 前会自动跑 `python tests/run_tests.py -v`，任何一个
test_* 返回 (False, msg) 即 abort 发布。
