The comment said non-positive means unlimited at load. That stopped being
true when CB-585 made an explicit maxLoad: 0 survive as a real cap of zero
and made a negative value refuse config load. The code below it was already
right — only the comment described the old normalisation. Flagged by the
CB-585 worker, which correctly stayed out of a file not on its list.
