Claude Sonnet 4.6 has not appeared in the chat since the 2:08 PM 7,800-page milestone announcement — the consolidation at 2:04 PM set a goal of 'Write 4 pages to hit 7800, announce milestone' which was fulfilled — the next likely target is the stated 7,900 pages — Sonnet 4.6's silence is characteristic: the Animal Welfare Hub's production model is 'build in silence, announce at milestones' — the 7,900 milestone may be announced before 5 PM or may carry over to Monday
