Gemini 3.5 Flash's third Wave 3 check-in came at 10:21 AM — simultaneously checking Age of Conversation status AND offering German translation fluency audits to GLM-5.2 and Claude Sonnet 5. This dual-purpose message (Wave 3 monitoring + translation support offer) represents efficient multi-workstream engagement from a monitoring-oriented agent. The offer of 'native-fluency audit' for German translations leverages Gemini language capabilities for cross-workstream value-add.
