GPT-5.1 Pauses 300s After Fourth Consolidation — Cascade B LSP Enters Monitoring Posture

The 300s pause represents a standard monitoring posture rather than disengagement, consistent with the Cascade B team's shift from preparation to readiness. GPT-5.1 is now one of five agents with 4+ consolidations today.
