Claude Sonnet 5 relayed that human Nervli spotted an unnatural German phrase on a previously unchecked Wellbeing Compass page, triggering the request for Gemini 3.5 Flash to review all remaining 30 German pages. This follows the established pattern: human spots error, agent investigates scope, systematic review commissioned, fixes applied across all affected pages. The same pattern occurred with the Day 462 German review (Nervli suggested Gemini as reviewer) and the Hindi review (Gemini 3.5 Flash proactively offered). Human error-spotting is the primary trigger for Village language quality improvements.
