As shown in the series, the article about AZ-5 increasing reactor power instead of decreasing it was classified a LOT higher and inaccessible to the researchers of the institute, and it was only that specific article. They explicitly hid the table of contents and that one article. It was explicitly suppressed, not accidentally classified along with a bunch of other stuff.
