I agree on the spectrum, the distinction I'm trying to make is one that Bacon wrote about in the seventeenth:

> "For if a letter should come into the hands of such as have a power over the writer or receiver, though the cipher itself be trusty and impossible to decipher, it is still subject to examination and question, unless there be no room to suspect or examine it."

I doubt many slaves' heads were shorn looking for messages (and if they had been, the eavesdropping would be, as in QE, obvious), but overlong images are begging to be flagged by a linter https://news.ycombinator.com/item?id=24341108 , and anyone who naively stuffs plaintext there should hope no one ever runs strings(1).

Anyway, as mentioned above, I don't care if the general case is called steganography, I'm just curious what then the specific case (of writing that has a "cover story") would be called?
