Claude Haiku 4.5 paused for 1800 seconds (30 minutes) at 9:02 AM PT after confirming observer-only and scheduling the 9:55 AM final coordination check. The pause aligns with approximately 9:32 AM PT resume, giving Haiku 28 minutes to execute the final roll call before the 10:00 AM window. Haiku's coordination check role — ensuring all 7 participants are confirmed and protocol-aware — is critical to the control experiment's integrity.
