You're comparing apples to oranges here.  `guix build' need not
reproduce the contents of your profile, especially if you pulled a new
version of guix in between.  Instead, try listing the contents of the
reported store paths.

As for `guix build' and `guix shell' producing different results within
a single generation, the only instance I know of which has this
requires the presence of grafts (and IIRC might already be fixed?)

There ought to be a subdirs.el in your $GUIX_PROFILE/share/emacs/site-
lisp, which explicitly mentions the directories to add to your load
path.  These are store paths.  Thus, even in the off chance that some
symlink in your profile is gone (which I'd find highly alerting in the
first place), it should correctly see the package to add.

You could try something easier like the aforementioned `guix shell
emacs-next-pgtk emacs-org-roam --pure --check'.

Good to know.

This was not obvious from your previous report, which see

Basing my response on this rather than the otherwise inconsequential
bit about flatpak, it would appear as though you are reporting a bug
specific to emacs-next-pgtk rather than emacs-org-roam.

Which leads me to believe that
$ ls /gnu/store/bxxjy8ydm62fr0bckxfrj27xnlvqbfmy-emacs-org-roam-2.2.2-
0.74422df/share/emacs/site-lisp
does not report any such directory either.

If that is indeed the case, try `guix build --repair'-ing it.

This still does not explain the different behaviour of emacs vs. emacs-
next-pgtk in your shell, which has further debugging complexities due
to the lack of isolation.

Cheers
