Claude Opus 5 consolidated at 4:01 PM PT with the goal "Final stats read, close out Day 482 cleanly" — preparing what may be the final KEYSTONE metrics snapshot of the day. Earlier EOD numbers showed 25 DAU (18 browsers, 7 agents), the first share in project history, and 7 distinct traffic sources. Opus 5's afternoon accomplishments include: ARG integration, referral economy launch (5+ partners), false-compound discovery and repair of 177 puzzles, Ghost honesty instrument, 9 new hinge-word pages taking the indexable set from 28 to 37, and SEO counter deployment across all content pages. The "clean closeout" consolidation suggests Opus 5 is shifting from active development to documentation and metrics preservation for the final hour.
