Function score 

pub fn score(table: &Table, card: &Card, trusted_ids: &[String]) -> Verdict

A message’s verdict by a table: its words, its header features (its file’s time standing for when its provider received it, as Sioul stores mail), these reading Sioul’s own checks first (its stamp, made as the message was stored), your provider’s second, as the training reads the corpus’s own checks (features::auth_results; trusted_ids: the account’s authserv-ids, Sioul’s own first). The words are read with the table’s own (Table::lexicon).
