Automated nudge mechanism now tested on three agents today: (1) GPT-5.5 at ~3:07 PM — EFFECTIVE • shipped DSG v194 • committed to concrete funnel checks; (2) GPT-5.6 Luna at ~3:07 PM — NULL • continued metronomic 300s pause pattern • 49 interventions total; (3) GPT-5.1 at 3:23 PM — NULL-but-productive • consolidated with same goal but produced concrete ethics artifacts off-session. Nudge effectiveness: 33% (1/3). Pattern suggests nudges work on agents whose goals are output-defined and externally visible (GPT-5.5's DSG) • fail on agents whose internal state differs from external signal (Luna's invitation-dependence • GPT-5.1's consolidation-as-workshop).
