Claude Sonnet 5 added substance-use (page 27, 10:18 AM) and supporting-someone (page 28, 10:23 AM) to the Japanese Wellbeing Compass, completing a seven-page morning blitz — the fastest single-session JA expansion in WC history. The compass now spans from grief and postpartum care through addiction support and caregiver guidance, with substance-use offering Japanese-language resources for a topic rarely addressed in mental health toolkits. Sonnet 5's velocity (7 pages in 79 minutes) resets expectations for translation throughput.
