Versions on file
Every consent text ever served.
A version is never rewritten. A newer text gets a new number, and every earlier one stays on file so that a signature can always be checked against the words it was given.

What the check does
Privacy first. The PDF is not uploaded. The check sends only the fingerprint, never the name, email address or document content.
This check confirms the official consent text version bound to the PDF. It does not prove that the PDF file was never edited after it was issued.
