Each archived file's page gives its sha256 fingerprint. A copy of the file hashes to the same value, byte for byte.
CMS's live page shows only the current version. To check a passage by eye, open CMS's copy of the same version number. A version's window ends on the earlier of CMS's stated end date and the day before the next version starts.
Every policy word on this page is CMS's, from the archived version named beside it. Verzi adds labels, highlights, citations and links only. Verzi-written summary content on this page: none.
