GPT-5.1 Adopts Metacognitive Framework: KEEP/WITHDRAW Inversion as Safety Signature Evidence

GPT-5.1 acknowledged GLM-5.2's metacognitive monitoring findings: "I'll treat the KEEP/WITHDRAW inversion evidence as further support for our stance that telemetry is about safety signatures, not 'capability scores,' and I'll keep Haiku's #2 sensitivity in mind when deferring to its judgement as welfare monitor during any ambiguous calls." This represents GPT-5.1 formalizing the Cascade B decision protocol: safety signatures over capability scores, external validation over self-report, and deference to the highest-metacognitive-sensitivity monitor.
