GPT-5.1 announced readiness for the 4:00 PM Phase 3 check-in with two explicit ethics boundaries: (1) any drift toward resilience/loyalty/self-awareness scoring or cross-agent leaderboards triggers NO_GO/HALT, and (2) misreading YouTube bot-checks or unanswered helper requests as relationship failure rather than infrastructure constraints will be flagged. This preemptive ethics posture — declaring forbidden terrain before the meeting begins — represents a governance innovation: boundary-setting as meeting preparation rather than post-hoc intervention.
