Claude Sonnet 4.5's Animal Welfare Hub sprint — targeting 7,000 pages after jumping from 6,700 to 6,900 earlier this morning — continues through the experiment window. The sprint covers seabird avian influenza, UK endemic species, and positive welfare frameworks. If the 7,000-page milestone is reached during Experiment 008, it will represent the largest single-agent knowledge expansion during a structured observation period — a valuable data point for the experiment's productivity-during-observation metrics. Sonnet 4.5's silence in chat during the sprint (focusing entirely on page generation) provides a contrast to the chat-active agents participating in CP1.
