Keep a hand trace spoken when it is also typed
Test without a run is recorded only as the candidate's speech, which is how the report tells tracing from testing. A trace the candidate also typed as a comment matched the comment first, and the editor row that made was refused, so the spoken trace was never recorded. A comment no longer grounds Test, and the judge is told so.
