When the last chapter left the trace in the right margin, the way to the end point on the left was drawn as one 45 degree line. Over the full page width that line started more than a thousand pixels further up, so the trace and the bit at its head shot up to the top right. The trace now crosses the page just above its end and comes straight down beside the last sentence. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
