Every document linked here is a work of the United States government and in the public domain.
The Federal Register's HTML and XML renderings are unofficial; the PDF on each item is the
official text, and that is the one to cite.

Counts are arithmetic over published fields, dates are printed as filed, and titles are verbatim.
Where we have nothing, this says nothing rather than estimating. The one-sentence agency summaries
are machine-written from those same fields and are labelled where they appear.
