For the whole set
This folder on GitHub
Two files belong to the whole set rather than to one paper: the formatting file the four mathematics manuscripts load for their page layout and title block, and the list written when the files were copied to this site, with every file's SHA-256.
The formatting file the four manuscripts share hypnos-paper.sty
