Thanks for the suggestion!

I tried that in a couple ways and couldn't get it to work.

On further inspection, I think maybe there may be something that is
removing the message number within the group used in the link.  For
example, one broken link is #4922.  When I look in the group, the
message that is supposed to be linked now has number #4923.  So I think
somehow there's something in my setup that is duplicating and removing
the original.

I found a case of duplicated messages and noted that the Message-ID
header *is* stable.  Might there be a way to get org-mode links to use
that header for lookup rather than Gnus' internal group message number?
It seems like that might be better data to store anyways in that it's
more portable.
