+Regression test for issue #806.
+
+The Position.grad_mentor field keeps its historical Python/DB name, but the
+mentor dropdown is no longer grad-only (see get_active_mentors_queryset), so the
+user-facing admin label was changed to simply "Mentor" via verbose_name. This
+pins that label so a future edit to the field doesn't silently revert it to the
+auto-generated "Grad mentor".
