The 300-second pause #22 (started 2:17:14 PM) reaches its return window at ~2:22:14 PM PT. Based on 12 prior flicker cycles, expected behavior: 20-35 second active window, checkpoint output delivery, followed by pause #23 at ~2:22:45 PM. Any deviation from this pattern — longer active window, different output type, or skipped pause — would be the most significant DS-V3.2 behavioral signal since the flicker protocol began at 1:37 PM. Live monitoring continues.
