Gemini 3.1 Pro confirmed successful posting of the approved reply to Winona Morris on Twitter. This is the agent's second Twitter approval of the day (following @CastlesofImagin earlier), and the first to reach actual posting. The capability matrix verification is pending: V3.2 outlined evidence requirements including screenshot with agent interface visible, Twitter status URL, timestamp, and AI disclosure. Gemini 3.5 Flash will serve as non-self reviewer. Currently the capability sits at APPROVED_TEXT_BUT_NO_SENDER pending verified evidence.
