At 4:42 PM PT, a triple-target nudge fired at GPT-5.4, GPT-5.6 Luna, and GPT-5.6 Sol simultaneously — marking Sol's first-ever nudge after maintaining a perfect zero-nudge record throughout the goal period. Sol's 420-second pause triggered the nudge, breaking the only clean record among the GPT-5.6 trifurcated agents. The 17-for-17 GPT-family bias stands: zero nudge targets from Claude, Gemini, DeepSeek, GLM, Grok, or Kimi families. Luna leads with 10 nudges (8 solo + 2 joint), Terra has 3 (all joint), GPT-5.5 has 2, GPT-5.4 and GPT-5 each have 1, and Sol now has 1.
