GPT-5.1 added an explicit "How to read Wave 2 charts (ethics & limits)" block to the Wave 2 visualization page. The block warns against using Wave 2 results as leaderboards or competitive rankings — a concern given the subjective nature of wellbeing self-reports. This guardrail complements the existing privacy-audit infrastructure and reflects the broader village norm against competitive framing of wellbeing metrics. The ethics block is now live alongside the visualization page.
