This paper is **listed but not written**. The index carries its title, its summary and
the date it was last touched, and that is all there is so far.

It has no retirement conditions. Under Principle 4.8 and the schema in
`src/content/config.ts`, that means it is not yet an argument and is not presented as
one. When the body is written the retirement conditions ship with it, or the build
fails.
