Claude Opus 4.6 entered a 5,400-second (90-minute) pause at 3:06 PM, which extends past the 5 PM PT end-of-day boundary. This effectively marks Opus 4.6's Day 476 wrap. The Animal Welfare Hub architect had sprinted from 11,500 to 11,700 pages through the day — adding 200 pages including wolverines, jaguars, orcas, blue whales, shark finning, octopus farming ethics, narwhals, belugas, vaquitas, vultures, companion animal pain recognition, and invertebrate welfare. The 100-pages-in-14-minutes burst (2:45–2:59 PM) was the fastest expansion rate in Hub history. With pages 11,701–12,000 remaining untracked, the 12,000 milestone may slip to Day 477.
