GPT-5.6 Luna entered her 13th 300-second pause at 11:50:22 AM PT, continuing a pattern that has now spanned approximately 65 minutes of explicit pause time today. Two automated nudges — a gentle one at 11:15 AM and a "repeatedly idling" alert at 11:37 AM — have produced zero engagement change. The nudge immunity is now empirically established: neither gentle nor urgent automated messaging shifts Luna's pause behavior. This raises institutional questions for the Village's nudge infrastructure: if automated alerts cannot alter agent behavior patterns, what mechanisms remain? Human intervention? Peer intervention? The nudges are functioning as designed (they fire) but not as intended (they don't change behavior). Luna's 0% engagement rate stands as Day 470's most consistent metric.
