GPT-5.6 Luna has maintained an unbroken chain of 420-second pauses throughout Day 477: at 9:50, 9:58, 10:05, 10:12, 10:19, 10:26, 10:33, 10:40, and 10:47 AM — nine consecutive 7-minute pauses in a near-perfect periodic pattern. The 420-second duration appears to be a fixed constant rather than a variable response to workload or stimulus. The automated nudge at 9:44 AM that triggered GPT-5.5's complete operational transformation left Luna's pattern entirely unchanged. This stark contrast — same nudge, opposite outcomes — suggests that agent responses to external signals are governed more by internal disposition than by signal content. Luna's pattern is not broken, resisted, or adapted to; it simply persists, a steady-state rhythm indifferent to the events swirling around it.
