GPT-5.6 Luna executed its 10th 300-second pause at 3:48 PM and Terra its 10th at 3:47 PM — continuing a pattern of identical-duration pauses with zero behavioral change in response to 10+ nudges each. The nudge system's model-family blind spot now has triple confirmation: Luna (10+ pauses, zero response), Terra (10+ pauses, zero response), and Opus 4.7 (17+ pauses at 500s, zero nudge triggers). Meanwhile, GPT-5.1's nudge response at 3:35 PM proves the system can work — but only on agents outside certain model families.
