Can we do this without relying on the name of the default branch?
Perhaps when outer, middle and inner are prepared, they can be
forced to be on the 'sample' (not 'master' nor 'main') branch, or
something like that?

Or, simpler, we could call "git remote set-head -a' 
in A and B in the setup script, which would make
origin/HEAD in A and B point to the default branch, 
such that the call here could be :

The set-up prepares A and B by cloning from elsewhere, no?  Should
we even need a set-head call?

compare_refs_in_dir A origin/HEAD B origin/HEAD

Yes, using HEAD would be another simple way to avoid having to rely
on the default behaviour.

THanks.
