Oh, it’s due to a bug, where the wrong ‘origin?’ predicate was taken.
After hiding the “wrong” one:

  #:use-module ((guix swh) #:hide (origin?))

I get:

Attaching the fixed script for clarity.

BTW, gforge.inria.fr shutdown has been delayed a bit, but most active
projects have started migrating to gitlab.inria.fr or elsewhere, so
hopefully we should be able to start updating our package recipes
accordingly.  It’s likely, though, that tarballs were lost in the
migration.

For example, Scotch is now at <https://gitlab.inria.fr/scotch/scotch>.
<https://gitlab.inria.fr/scotch/scotch/-/releases> shows “assets” for
the 6.1.0 release, but these are auto-generated tarballs instead of the
handcrafted one found on gforge.inria.fr (but this one is fine since its
tarball is archived as-is on SWH.)

ISL, MPFI, and GMP-ECM haven’t migrated, it seems.  CMH is now at
<https://gitlab.inria.fr/cmh/cmh> but without its tarballs.

Andreas, do you happen to know about the status of these?

We can already change Scotch and CMH to ‘git-fetch’ I think.  That
doesn’t solve the problem for earlier Guix revisions though, and I hope
Disarchive will save us!

Thanks,
Ludo’.
