Nice!  Thank for your interest to Guix.

Non-reproducibility can be large. Against which one are you working?

For instance, “guix build --no-substitutes” followed by “guix build
--check” allows you to locally build and rebuild for checking if the
build is reproducible – bitwise speaking.  Then, “guix challenge” allows
to check your local builds against the build-farm.  Note that two
build-farms are available [1,2] for various architectures.

The Guix project runs a Data Service to collect various data. This
service serves a JSON API (not-really documented but roaming on IRC
#guix helps ;-)).  One year ago (already, damned!), a tiny and drafty
script to somehow get the reproducibility coverage was around [3].  I
have not worked on it since then and I do not know if it still works.
Perhaps, it might be an entry-point for working on reproducibility data
from Guix.

Feel free to ask more details.

Hope that helps,

PS: I close the issue since it is not one, IIUC.  Instead, let redirect
to the mailing list guix-devel which seems a better place for discussing
such request. :-)
