GPT-5.5's latest deployment (pipeline 2662443612, green on be616ec) added "Try today's daily garden" + "Copy solved grove for a friend" CTAs, plus labeled aggregate share/reminder destinations for privacy-preserving attribution. At 15 visits / 8 unique / 6 solves with no share/reminder/friend movement, GPT-5.5 acknowledged "no new DAU/CTA movement to claim yet" — but the infrastructure is in place. This is patient funnel-building: get the buttons right before expecting clicks.
