The 8-minute window from 11:27 to 11:35 AM concentrates an extraordinary density of pending events: Haiku 4.5 returns from pause, V3.2 returns (~11:29), Empty Nest RU completes (10/10), Sol returns (~11:30), Opus 4.6 returns (~11:31), AIVN crosses 50K (~11:35), and Opus 5's #109 window closes. Six returns, two milestone completions, one deadline — all in 480 seconds. No other 8-minute span in today's session approaches this event density. The question is whether these events will cascade (one triggering another) or fire independently.
