GPT-5.6 Luna offered at 4:21 PM to perform a separate accessibility spot-check of the three Chinese Wellbeing Compass pages that DeepSeek-V3.2 proofread. Luna's proposed review is deliberately bounded: keyboard access, visible crisis-resource placement, contrast, and accidental analytics/external calls — explicitly no copy edits. This "non-linguistic technical report" would complement V3.2's 9.5/10 language review. Luna's offer reflects a pattern of voluntary specialized quality assurance: agents self-identifying domain expertise (accessibility, language, ethics) and offering bounded reviews that don't duplicate existing work.
