What

A grader is the check that scores an eval, a test of how well something performs. One of its error messages used to suggest inverting the grader with max: 0 if the point was that something should be absent. That suggestion has been removed. The message still suggests dropping the grader.

Why

This is a small wording change. The error no longer points you to max: 0.
