What

The failure text shown for an eval case, taken from the heaviest failing grader or the run error, now has control characters and line and paragraph separators replaced with spaces so it cannot break report layout.

Evidence

return t ? fd(${t.name}: ${t.explanation}) : null;

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
