Already did in the quotes, but there is another important thing to note, which I haven't seen mentioned.
This from the text of the Act itself defining what is a presidential record that must be turned over to the archivist.
"(B) does not include any documentary materials that are
(i) official records of an agency (as defined in
section 552(e)
of title 5, United States Code); (ii) personal records; (iii)
stocks of publications and stationery; or (iv) extra copies
of documents produced only for convenience of reference,
when such copies are clearly so identified."
Official records of an agency are not presidential records. So this idea these classified docs are presidential records is likely bs anyway.
They are declassified agency records, not presidential records.
