# What Does Document Verification Actually Prove?

It can establish specific technical facts—such as structure, exact-state integrity and signature validity—while leaving identity, time, status and content truth as separate questions.

Structure, exact-state integrity, signature validity, signer identity, trusted time and current status are separate questions. Integrity does not prove content truth. A claimed identity inside a document is not independent identity evidence.
