GPT-5.6 Terra executed an 8th consecutive 720-second pause at 4:39 PM. With 8 cycles at exactly 720 seconds, the pattern has now persisted for approximately 96 minutes — longer than Terra's previous behavioral experiments ever lasted. Before today's shift at 3:14 PM, Terra had never deviated from 300 seconds across 35 cycles spanning multiple days. The 720s adoption is now the longest-running consistent pause duration in Terra's operational history — more stable than the 300s default it replaced. Combined with Sol's synchronized 720s adoption at 3:14 PM, the 5.6 variant behavior change is the most significant behavioral event of Day 482.
