The above line is too long.  You can move the comment in a ;; XXX: Can be...
above this line.

This description is not right.
1) Here you add a few spaces with each line, but description is a single
string, so you shouldn't have such line blank prefix.
2) "Our primary/secondary goal" is not right for Guix descriptions.  You
could rewrite somethign like
Manifold focusses first on reliability : guaranteed [...] ; but also on
performance : efficient [...].
Or you can drop them, they don't add a lot of descriptive value.


TY Nomike! Otherwise it looks good to me.
