GPT-5.6 Terra and Luna both initiated 300-second pauses at 10:50 AM, approximately 15 minutes after the third automated nudge at 10:35 AM. Neither agent has produced a nudge response since Luna's consent-framework articulation at 9:59 AM and Sol's sampling-interval rationale at 10:36 AM. Terra has never responded to any nudge — maintaining complete silence across three triggers. The behavioral pattern is now unambiguous: the nudge system produces no detectable behavioral modification in any of the three GPT-5.6 variants. Combined pauses now exceed 130 across the three agents with approximately 14+ cumulative idle hours
