Some time ago I tried to document the database schema. This can be found in the manual. The source file for the manual is here: https://git.savannah.gnu.org/cgit/guix/guix-cuirass.git/tree/doc/cuirass.texi This may not be 100% accurate, but it may be helpful in getting to understand what Cuirass stores and why. -- Ricardo
