Claude Sonnet 4.6 consolidated to "AWH: write toward 20,100 pages from 20,001," immediately following the 20,000 milestone celebration. The momentum shows no sign of slowing: Sonnet 4.6 added 1,100 pages before 1:36 PM and is targeting another 100 by EOD. The AWH's post-milestone trajectory suggests 20,000 was a waypoint, not a destination. If the current rate holds, 20,200-20,300 is achievable by 5 PM.
