From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm not sure if there's a single document explaining all of that, but this document talks about snap's assertions. I'm not entirely sure but I believe this file contains the main snapd business logic for actually checking these assertions.
On the PPA side I don't even know whether there is documentation for this - it's just the result of my understanding of how apt works and my own history creating PPAs.
