Have you made a trial merge to 'seen' and 'next' to see how well
this change plays with other topics in flight?

Pelease remind me the reason why we use the_repository here, even
though a few lines above we are already using the caller-supplied
repo.

Also setup_git_env_internal() no longer exists in 'seen', if this
topic wants to play well with cf1687a41c (setup: split up concerns
of `setup_git_env_internal()`, 2026-07-07), you'd need to coordinate
the other topics and their author(s) before relying on the presence
of what they are removing.
