Function authored_dedup_key 

pub fn authored_dedup_key(
    family: &str,
    target_ref: &str,
    action: ActionKind,
    content: &str,
) -> String

The dedup key of an AUTHORED executable proposal: dedup_key plus a fingerprint of the proposal’s content. An analyzer finding is “this target has this kind of problem”, so content is rightly excluded; an authored lesson is “do this”, and two different lessons on the same entity must both reach the queue while the same lesson re-authored must not. The fingerprint is over the normalized text — case-folded, non- alphanumerics dropped, whitespace collapsed — so a rewording that changes no word is the same lesson and one that changes a word is a new one (a semantic near-duplicate is the reviewer’s call, not this key’s).
