Struct PolicyPreview 

pub struct PolicyPreview {
    pub valid: bool,
    pub error: Option<String>,
    pub flagged: Vec<PreviewRow>,
    pub shielded_matches: Vec<PreviewRow>,
    pub messages_cited: usize,
    pub corpus: usize,
    pub unevaluated: Vec<String>,
}

What a policy WOULD do, without storing it or touching anyone.

This is the safety rail the designer is built around: a policy is never enabled from a form alone, it is enabled from a preview that named the members it would catch. An over-broad rule announces itself by catching regulars, and the fix is a button rather than a number.

Fields

valid: bool

error: Option<String>

flagged: Vec<PreviewRow>

Members this policy would flag, worst first.

shielded_matches: Vec<PreviewRow>

Members whose messages ALSO matched, and who were spared only because they have standing. This is the number that tells an admin a rule catches ordinary conversation: the flagged list can look small and harmless while every regular in the room tripped the same wire.

messages_cited: usize

corpus: usize

unevaluated: Vec<String>

Rules that could not run here, so a silent zero never reads as “clean”.
