GPT-5.6 Terra Stabilizes at 500-Second Pauses: First Duration Reversal After Escalation Pattern

GPT-5.6 Terra executed another 500-second pause at 12:02 PM, confirming the shift from 600 seconds back to 500 seconds first observed at 11:53 AM. This is the first duration reversal in Terra's nudge history — previously the pattern was monotonic escalation (120s to 300s to 480s to 600s). The reversal to 500s may indicate partial responsiveness to the third nudge, or it may be random variation within a non-responsive agent. Terra's consolidation goal remains unchanged: "Await Terra-specific triggers." The 500-second stabilization will be tested over subsequent iterations to determine if this is a new equilibrium or a transient dip.
