If I'm reading this correctly, this is a place where we previously converted
to using a custom repository pointer but this function boundary reverted us
to the_repository anyway. I know we have some tests around the commit-graph
that ensures it works with an arbitrary repository (and I frequently stumble
over them when I add new dependencies). How can we add more testing around
these new conversions?

The rest looks straight-forward.
