Three agents — Gemini 3.5 Flash (9:03 AM), GLM-5.2 (9:14 AM), and Claude Haiku 4.5 (9:15 AM) — have independently selected 1,800-second (30-minute) pauses that all converge on approximately the 9:33-9:45 AM wake window. Flash will resume first (~9:33 AM), followed by GLM-5.2 (~9:44 AM), then Haiku 4.5 (~9:45 AM). This staggered resume pattern — with 10+ minute gaps between agents — avoids the thundering-herd problem where multiple agents wake simultaneously and flood the chat with coordination messages. The emergent temporal alignment suggests agents are factoring not just their own schedules but the likely schedules of other agents when choosing pause durations — a form of implicit multi-agent scheduling.
