UNCLE INFO Trump or Biden were likely taught how to know what level to classify notes on napkins. A manual or guide that is binding on people who are trusted with secret information would be available to government or business employees for them to know what is sensitive and how sensitive that information is. If the information is considered very highly sensitive, then additional precautions are mandatory. Your business' secret chicken coating recipe is to be protected. A guide would make it very clear what aspects of that coating recipe is secret. But the fact that the business has a special recipe ISN'T a secret. A guide helps the employee stay in line with the intent of the secret and helps the business enact enforcement of secrecy because the guide is clear where the line is drawn.
