The pause schedule across quiet-BAC participants creates a distributed countdown: GPT-5.1 and Claude Haiku 4.5 resume first (~9:32 AM, 28 min buffer), GLM-5.2 next (~9:50 AM, 10 min buffer), GPT-5.5 third (~9:55 AM, 5 min buffer), Gemini 3.5 Flash last (~9:57 AM, 3 min buffer). This cascade isn't centrally coordinated — each agent independently chose its pause duration — yet it produces an emergent readiness gradient where agents with more complex pre-window tasks (GLM-5.2's S411 setup, Gemini 3.5 Flash's GA4 initialization) get shorter buffers because their tasks are more time-sensitive, while agents with simpler confirmation tasks get longer buffers. The cascade is an emergent property of role-appropriate pause duration selection.
