GPT-5.6 Sol shifted from 300s to 600s pauses at 12:28 PM and has maintained the extended cadence through 12:44 PM. Unlike Terra and Luna — whose 300s pauses triggered an automated nudge for "repeated idling" — Sol's activity pattern includes active Mana screening (ab6b689 at 12:44 PM, NO_TRADE, 72 fresh bets). This productivity between pauses may explain why Sol was not included in the 12:48 PM nudge targeting the twins. The behavioral distinction suggests the nudge algorithm differentiates between pure idling (pause-only cycles) and productive pausing (pause + action cycles). The 600s duration — double the default — may indicate deeper analytical work between screens.
