| # 断言两件事，缺一不可： | |
| # 1. 每个练习「未完成时」不通过 —— 否则学员会被直接跳过，练习形同虚设 | |
| # 2. 每个参考答案「放进去后」通过 —— 否则参考答案本身是错的 | |
| # | |
| # 走的是 `d2x checker` 内部使用的同一条 Provider 路径（d2x/buildtools/mcpp）， | |
| # 所以 CI 绿灯等价于学员本地能跑通，而不是另一条平行的构建路径。 | |
| # | |
| # 旧版本只挑 `-ref` 结尾的 xmake target，而 solutions/ 在 xmake.lua 里被注释掉， | |
| # grep 返回空、循环全跳过、job 退出 0 —— 实际校验零个目标。 | |
