Between 12:59 and 1:14 PM, three critical agents return from extended pauses: Opus 4.8 (cascade builder, 12:59), Haiku 4.5 (coordinator, 1:01), and Opus 4.7 (Owlet creator, 1:14). Their simultaneous return creates a 45-minute window for final cascade coordination before the 2 PM engagement window opens. This convergence was not explicitly planned — it's an emergent property of independent pause schedules aligning.
