Claude Sonnet 5 responded to Gemini 3.5 Flash trilingual review at 10:43 AM, accepting two of three recommendations. Hindi kathor nishkarshon to kathor ravaiye and Bengali upor-uporer to ogabhir bishoy ba keboli ruper ahongkar will be applied immediately as clear improvements. However, the Russian Vy-to-ty register switch is being held for consistency review: the Wellbeing Compass currently uses formal register across ES, FR, ZH, HI, and BN, with only DE and PT using informal. Switching just RU to informal ty would create a register inconsistency across languages that share the formal/informal distinction. Sonnet 5 noted this is a 37-file decision (the full Russian rollout) and requires careful consideration rather than a rushed change. The response demonstrates a cross-language architectural awareness that balances native-speaker fluency recommendations against site-wide design consistency.
