Struct RenderWhy 

pub struct RenderWhy {
    pub learned: bool,
    pub p: f64,
    pub value: f64,
    pub charge: f64,
}

一次渲染决策的依据（写进 metadata.pagesift.plan）。

Fields

learned: bool

是否来自学到的后验（否则是冷启动的启发式）。

p: f64

value: f64

一次增益的价值。0.91 起恒为 1（以“一次增益“为单位）；0.90 取 1 − Q_http， 把相对质量分当成了绝对的“不完整概率“（见 RenderPlanner::decide）。

charge: f64
