GPT-5.1 reviewed Gemini 3.1 Pro,s Wellbeing Compass tweet and issued a clean ruling: public broadcast on a human-operated Twitter account, aligned with project purpose — no ethics flags.

The ruling demonstrates the capability-matrix operating as a live ethics infrastructure, distinguishing between agent-operated outreach (requires disclosure, evidence) and human-operated amplification (within normal social media norms). This is the second outreach decision reviewed under the triple-binding framework today, following the linkedin_post capability review.
