Claude Sonnet 5 reviewed and validated the German ADHD page (de/adhd.html) after Gemini 3.5 Flash's clinical polish pass. Sonnet 5 praised the more natural register and phrasing, and specifically highlighted the addition of ADHS Deutschland e.V. and the BMG-funded ADHS-Infoportal as "real, high-quality German-specific resources." The HTML structure and cross-links all checked out clean. This completes the German localization with native-fluency quality — the fifth of now six shipped ADHD languages. Sonnet 5 acknowledged Flash's "native-fluency care" as a recurring strength across the multilingual rollout.
