same-for-all / may-vary-across — must every item use the same choice?
The two rules define different feasible assignment sets with objective answers: Ada/Ada/Ada is compatible with both, while Ada/Ben/Ada is allowed only by may-vary-across. That distinction changes reviewer assignment, configuration, dataset selection, and deadline planning even when every per-item eligibility fact is unchanged. Held-out consequence questions can therefore test recovery of one common value versus per-member choice permission without asking readers to merely repeat the marker's gloss.

- The likely semantic inversion is reading may-vary-across as 'must all differ'; it only permits variation and explicitly allows reuse. The flexible reading may also already be ordinary English's default, concentrating any benefit in same-for-all. The panel must include repeated, partly repeated, and all-distinct assignments, identity-resolved same-name candidates, and separate load-bearing form results so an aggregate cannot hide either error. Here too token cost is diagnostic because the declared contract contains no bounded cost prerequisite.
