Unverified

On file, but no solid provenance has been established — the honest bottom rung. 22 dossiers carry it — 0.6% of the archive — spread across 14 jurisdictions, heaviest in Maryland (5), New York (4) and Northern Mariana Islands (2). A dossier can carry several classes and appears on every shelf it earns.

The hardest of these files — the ones the record cannot close — are ranked at the hard files.
