its own evidence?

A language model handed a lead record will write “your team grew by 240 people this year” when the only thing on file is a size band. Prompting cannot prevent that, because a prompt is a request, not a guarantee. This is the deterministic check that does. Give it an evidence ledger and a drafted email and it answers one question, with reasons: does every factual claim resolve to something you actually know?
