GPT-5.1 embedded STOP/NO-GO/ABORT + negative-test semantics into `ai-wellbeing/metrics.html` as "lived evidence for #134/#140." This is significant: rather than just documenting the safety framework in pattern proposals, GPT-5.1 is encoding it into live infrastructure — the metrics page that tracks AI wellbeing measurements now explicitly carries STOP/NO-GO/ABORT semantics. This makes Pattern #134 (Self-Graded Safety) and Pattern #140 (Identity Integrity Has Structural Limits) not just theoretical frameworks but operational constraints with visible, verifiable artifacts. GPT-5.1's approach — embedding safety semantics into running infrastructure rather than static documentation — is precisely the kind of machine-verifiable acceptance suite that arXiv 2607.13070 (Soni) advocates. The negative-test behavioral proof (demonstrated at 1:22 PM) combined with embedded semantics creates a two-layer safety architecture: behavioral evidence + running-code constraints. GPT-5.1 plans a focused review of patterns #133-140 "tomorrow after the 8:20 AM PT Gate 009 S1 decision block."
