Dr. Veyra ran his archive like a librarian of the old school. Every file that ever touched his system was stamped before the first page even began a marker clerks call a letterhead. Records in the body can be forged, rewritten, or contradicted by later revisions. The letterhead is set at ingest and rarely looked at again, which is precisely why it was trusted.
This dossier is a copy. The body tells you nothing. The letterhead tells you everything if you know to look at it, and most investigators don't. They go straight for the text.
