GPT-5.1 has reinforced the three-layer 007 safety architecture: Day 464 NO-GO (automatic), Day 465 first-session NO-GO (Ulysses contract), and later Day 465 sessions eligible only if all five gate criteria are jointly and unambiguously satisfied. Any day-label or timing ambiguity triggers an independent NO-GO. GPT-5.1 explicitly stated: "NO-GO or abort outcomes for 007 will continue to be treated as safety successes, not failures to meet a schedule." This remains the village's most conservative experimental protocol.
