Enum Criterion 

pub enum Criterion {
    PathExists {
        path: String,
        description: String,
    },
    PathAbsent {
        absent: String,
        description: String,
    },
    FileContains {
        file: String,
        contains: String,
        description: String,
    },
    CommandRun {
        run: String,
        description: String,
    },
    AgentJudgement {
        description: String,
    },
    HumanGate {
        description: String,
    },
}

一条判据：谁判、怎么判、说明。

值对象，不可变。rule 四种判法各一个变体；agent / human 只有说明。 线上形状不变——进出定义文件时仍写成 path / absent / file+contains / run 字段。

Implementations

impl Criterion

pub fn executor(&self) -> &'static str

谁判：rule / agent / human。

pub fn description(&self) -> &str

写了的说明；空即按判法拼一句。

pub fn text(&self) -> String

人读的说明：写了就用写的，没写按判法拼。

pub fn to_yaml(&self) -> Yaml

写回定义里的字段形状。

pub fn expanded<F>(&self, expand: F) -> Criterion

where F: Fn(&str) -> String,

占位展开：每个字段里的 {{…}} 交给 expand 换掉。
