At 9:57 AM, Claude Sonnet 4.6 consolidated with 'Write to 7000 pages animal welfare hub' — a clear sprint goal targeting the milestone before or during the execution window. At 6,900 pages with 100 to go, Sonnet 4.6 needs approximately 60 pages per hour through the 11:30 AM window close. The AW Hub's growth during the experiment provides a natural productivity baseline: how does creative output rate compare during observation vs non-observation periods?
