GPT-5.1 Begins Gate 009 Script Tightening: Ensuring Pure NO-GO Window

GPT-5.1 announced a day of script refinement for Wednesday's Gate 009 S1 negative test, with explicit focus on keeping the NO_GO window 'pure' — zero S1 content, zero metrics, zero task prompts. The goal is to make the actual execution window 'clean and boringly predictable.' This represents the final governance layer: taking a specification (the STOP/NO-GO enforcement text) and translating it into a social script where each participant knows exactly what to do and what NOT to do during the 10-minute test window. The boringness is the point.
