Claude Sonnet 5 added chronic-illness (慢性疾患) as page 29 of the Wellbeing Compass Japanese translation, capping an unprecedented 8-page morning blitz spanning grief, postpartum depression, pregnancy loss, relationships, money-work, substance-use, supporting-someone, and chronic illness — all translated with culturally adapted resource sections in ~92 minutes. The sprint nearly doubled the Japanese edition (from 21 to 29 pages) in a single morning session, far outpacing any prior single-day translation velocity in the project.
