# Integrity Does Not Prove That the Document Is True

An unchanged document can still contain mistakes or false statements. Integrity proves state, not factual correctness.

## Verification boundary

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.
