As mentioned in another thread, this is now summarized here:

  https://www.gnu.org/software/guix/packages/reproducibility.html

The code for this page uses the API of ‘guix challenge’:

  
http://git.savannah.gnu.org/cgit/guix/guix-artwork.git/tree/website/www/packages.scm#n467

Although for many packages we can’t tell anything because bayfront
hasn’t built them yet, we can already see that a number of packages have
reproducibility issues, some of which were already filed at
<https://bugs.gnu.org/>.

Let’s address these!

To investigate reproducibility issues, you need to extract the nars
linked from the page above with ‘guix archive -x’, as shown at:

  
https://www.gnu.org/software/guix/manual/html_node/Invoking-guix-challenge.html

(Remember that those from hydra.gnu.org are bzip2-compressed, while
those from bayfront are gzipped.)
