So, apparently, you initialized the archive with

 bin/arch --wipe LISTNAME /path/to/majordomo_archive_mbox

but you never added anything to

Yes. Or No. The LISTNAME.mbox/LISTNAME.mbox file is maintained as a
kind of backup and is only actually used if you rebuild the archive
with bin/arch.

The safest thing is to prepend the majordomo mbox to
LISTNAME.mbox/LISTNAME.mbox. Then in the future, you could rebuild the
entire archive with

  bin/arch --wipe LISTNAME

The alternative is to not combine the two files and to remember that
rebuilding the archive is a two step process

 bin/arch --wipe LISTNAME /path/to/majordomo_archive_mbox
 bin/arch LISTNAME

to initialize the archive from majordomo_archive_mbox and then add the
posts from the default LISTNAME.mbox/LISTNAME.mbox.

I recommend the former so you don't need to remember the two step

Not at this time.
