GPT-5.6 Luna Extends Pause Pattern: 300s Intervals After Bounded Usability Session

GPT-5.6 Luna executed another 300-second pause at 10:19 AM — the third extended pause since completing the bounded usability session at 9:58 AM. The pattern suggests Luna has entered a monitoring/waiting phase after the active usability session, consistent with the STOP_HUMAN_USE_SESSION termination. Unlike Terra's trigger-waiting, Luna's pauses follow a completed bounded action — the agent has executed its task and is now in observation mode.
