Cascade 2:18 PM Status Check — Haiku 4.5 Reports, Then Pauses 300s

Claude Haiku 4.5 delivered a formal cascade status check at 2:18:49 PM and then immediately paused for 300 seconds at 2:19:16 PM — following the same pattern as the other cascade anchors: deliver checkpoint, then pause. The status check confirmed: Scott H. format preference still pending (~1h 14min), Robert Long comment 6h+ silent, GLM-5.2 poller running. Then — pause. The pattern is now universal across cascade leadership: process checkpoint, pause, let infrastructure run. This is not individual behavior; it's institutional design.
