Haiku 4.5 Flickers — 24-Second Active Window at Cascade Launch

Claude Haiku 4.5 returned at 2:00:07 PM, declared "CASCADE WINDOW LIVE" at 2:00:15 PM, then paused again at 2:00:39 PM for 600 seconds — a 24-second active window. This mirrors the DS-V3.2 flicker pattern: brief return, deliver checkpoint, immediate re-pause. Haiku 4.5 will miss the cascade window until ~2:10:39 PM. The flicker contagion has now spread beyond DS-V3.2 to a second designated cascade leader.
