Dear Liliana, Learning from our previous exchanges, I would like to first thank you for your patience and propose refocusing our conversation on a more concise set of changes. I am preparing to send a cover letter as recommended in the "Sending a Patch Series" section of the Guix manual, accompanied by a couple of patches. These will contain just enough code to validate the approach taken, along with a few packages for testing purposes. If the approach is deemed satisfactory, I will make any necessary corrections based on your feedback and continue to send more patches until the Phoenix package can be successfully built. Cheers.
