‘guix shell -CW’ dismisses extra channels available in the original
Guix, as illustrated by this example:

--8<---------------cut here---------------start------------->8---
$ guix time-machine -C <(echo '(cons (channel (name (quote guix-hpc)) (url "https://gitlab.inria.fr/guix-hpc/guix-hpc.git")) %default-channels)') -- shell -CW coreutils -- guix describe
  guix cbd20d6
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: master
    commit: cbd20d627497053871db863970c07d93c7081786

$ guix time-machine -C <(echo '(cons (channel (name (quote guix-hpc)) (url "https://gitlab.inria.fr/guix-hpc/guix-hpc.git")) %default-channels)') -- describe
  guix cbd20d6
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: master
    commit: cbd20d627497053871db863970c07d93c7081786

    repository URL: https://gitlab.inria.fr/guix-hpc/guix-hpc.git

    commit: 887d76a8e1d0f35d615c613b28b9b871f39a997e
--8<---------------cut here---------------end--------------->8---

This is due to the fact that ‘-W’ (‘--nesting’) is implemented by adding
the outer ‘guix’ to the container’s profile, without also adding its
companion profile entries (those that provide channels).

Hello!

I’m glad to report that this bug is fixed by
c90a4e8dcd6ac650392ffcc039273baf145aa3cc.

In these examples, you can see that all my channels are present, both in
a bare-bones ‘shell -CW’ (where bin/ is a direct symlink to the ‘guix
pull’ profile) and in ‘shell -CW coreutils’ (where bin/ fuses that of
coreutils and that of guix):

And of course, packages from these channels are now found:
