> Applied with a followup commit to address ‘guix lint’ warnings.

Thank you! I was unsure what to do about those lint errors. I updated
cedille with the proper fetch to fix the lint issues with it.

>  Also, it fails to build for me

I included a second patch to fix the build issue. It looks like this line
in the Makefile would cause this problem:

./ial/ial.agda-lib:
git submodule update --init --recursive
