Struct KnownAnswer 

pub struct KnownAnswer<'a> { /* private fields */ }

A known-answer hint observed in an incoming query, used to suppress our outgoing answers when the asker already has the same record.

carries src so the service can scope the hint to the querier that supplied it. Hints from sources that did NOT issue a Question in the current response cycle are dropped — without this, an attacker could inject KAS hints during a legitimate questioner’s jitter window and suppress the response.
