The counters did their job and then ran out: 4,090 rows drawn against 94,815 skipped, the tallest drawn block down from 36,982px to 1,765px, and drawing still took 30.9ms at the median. Almost nothing is being recorded and recording is still the expensive phase, so the next question is not "how much" but "where" -- and there are only two answers left. Either the little that is drawn is somehow costly, or the time is not inside the transcript at all and every count above is beside the point. So the draw is timed at three levels that nest: the whole transcript, one row, one block. If the transcript's own figure is most of the frame's draw, the cost is ours and the rows and blocks say which. If it is a fraction of it, the frame is being spent somewhere this has not been looking. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
