Function auth_results 

pub fn auth_results(
    headers: &RawHeaders,
    trusted_ids: &[String],
) -> Option<AuthResults>

The authentication results the features read of a message as it is stored: Sioul’s own first (its stamp, under this installation’s id, which ends in .invalid), your provider’s second (the account’s other trusted ids), as the lanes, the forgeries and the senders read them. The training corpus keeps the message as the server holds it, without the stamp, and Sioul’s checks beside it (sioul_learn::corpus::Checked), which it reads with stamp_results first: the same verifier on both sides.
