答案契约校验

这是什么

Does the text describe checking Jev's answer shape before acting, such as choice in candidates, probabilities summing to one, or discarding out-of-range values?

这些不算

Trusting the response as-is.

这道题在 Jev 眼里长这样

jevbooks 就是拿这道题去问 Jev 每一份 README 的。抄结构，别抄字面。题目原文是英文——这就是发给 Jev 的字面内容；state 可以是中文。
