No such classification level I have ever heard of, and I have had clearances of several levels over the years.
"highly confidential" is a level that peons like us aren't supposed to know exists!
Agreed. Perhaps the author does not understand classification. Or, perhaps the author was told about the classification from a source who opined the info was
“Highly Confidential”.
I guess you have forgotten the part about the ‘over/under’ thereabouts, almost uber-secret, Frank level of secrecy.
On second thought,
Nah.
