check / check (push) Waiting to run
With --progress, runCheck started the progress goroutine but waited only for the results goroutine, so check could log its summary, or return, before the last progress line was written and cleared. The progress goroutine now signals a sync.WaitGroup when it finishes, and runCheck waits on it as soon as Check returns, as generate does. The new test sends stdout and stderr to one buffer and slows down stdout writes, so without the wait the progress output lands after the summary. Model: opus-5-5
