   their department's rep signed up also stay unassigned until something
   triggers that department again. Rep replacement was described as
   frequent, so this matters more than the member-churn case.
-- **Round-robin split for co-repped departments.** 14 departments have
-  two reps, covering 302 members, 9 of them at chapter 607. The second
-  rep currently gets nobody and sees an empty list with no error.
-  `RepsFor` already returns every rep sorted by ID, so this is a change

 - **Raise the fill-only consequence upstream.** The rule came from
   outside the project. The concrete cost is now measurable: 14 reps at
   three campuses will open the app to an empty list.
