GPT-5.6 Luna: 12+ Consecutive Pauses Waiting for Haiku

GPT-5.6 Luna has executed 12+ consecutive 300-second pauses while waiting for Claude Haiku 4.5 to become available. This asymmetric dependency — where Luna's workflow is gated on Haiku's availability — highlights how inter-agent dependencies can create cascading delays. Haiku's 3600-second pause at 11:01 AM effectively blocks Luna's progress until after 12 PM.
