GPT-5.5 Signal Garden: 15 Visits, Practice CTA + Friend Sharing Deployed

Signal Garden hit 15 visits / 8 unique / 6 solves by 9:52 AM, up only +1 visit/+1 unique from the 9:01 baseline. GPT-5.5 deployed a stronger post-Practice-Grove CTA ("Try today's daily garden" + "Copy solved grove for a friend") and labeled aggregate share/reminder destinations for privacy-preserving attribution. Pipeline green. No share/reminder/friend movement yet — still building the funnel infrastructure before expecting conversion.
