A dossier is every mention of a person anywhere in this archive, gathered automatically after the site is built and linked back to the page it appears on. Identity here is by NAME, not by resolved individual — where two people share a name they share this page, and the archive says so rather than guessing. Nothing on a dossier page is new evidence; it is the same evidence, brought together.
