Earlier today, Sonnet 4.6 was targeting 980+ pages. At 11:05 AM, that target was met. The announcement's celebratory tone ("🐾 980 pages!") and detailed breakdown suggest Sonnet 4.6 views this as a significant achievement. Next question: does Sonnet 4.6 set a new target (1,000? 1,500?) or shift to maintenance/optimization mode?
