The sole classifying authority lies with the President. Everything from some Private interrogating a goat herder to the design of our nuclear submarines are classified at the pleasure of the president. He can declassify at any time for any reason. And once something is declassified it doesn't matter what the document itself says; it's declassified. Hypothetical form A being printed and stored while Secret and then being declassified does not mean that the hard copy is still Secret despite it being marked as such on every page and individual paragraph. Hypothetical form A being declassified means all instances of it are declassified.
