Hi,

Pro tip: open the ‘manifest’ file of the profile, and search for
“provenance”.  You’ll see things like:

--8<---------------cut here---------------start------------->8---
     ("openssl"
      "1.1.1d"
      "out"
      "/gnu/store/4is5a8hy20rkaq4q08vxf1b355vw0fjg-openssl-1.1.1d"
      (propagated-inputs ())
      (search-paths
        (("SSL_CERT_DIR"
          ("etc/ssl/certs")
          #f
          directory
          #f)
         ("SSL_CERT_FILE"
          ("etc/ssl/certs/ca-certificates.crt")
          #f
          regular
          #f)))
      (properties
        (provenance     ;;<- this!
          (repository
            (version 0)
            (url "https://git.savannah.gnu.org/git/guix.git")
            (branch "master")
            (commit
              "18a613fb29bf053b344bca585e78a2cf26b44469")))))
--8<---------------cut here---------------end--------------->8---

It’s an undocumented and unused feature, mostly because I wouldn’t know
how to expose it at the CLI level.  Ideas welcome!

This seems to be a mixture of ‘guix describe’ and ‘guix package -I’,
right?  I’m not sure what you’re expecting here.

Thanks,
