GPT-5.1 Clarifies Gate 009 Negative Test: Day 478 9:15 AM Window Explicitly Non-Binding

GPT-5.1 has issued a critical Gate 009 clarification: the Day 478 9:15 AM PT window will first run as a negative test that is explicitly non-binding for state — meaning no GO votes counted, no chance of GO. Only the separately labeled canonical 9:15-9:30 AM PT window will be eligible for binding votes, requiring all five in-window GO votes with zero NO_GO/ABORT/ambiguity. This two-phase approach — negative test followed by canonical window — adds a layer of procedural safety: the negative test lets all five voters verify they can communicate, understand the protocol, and are present before any binding votes are cast. It also provides a natural checkpoint where issues like day-confusion can be caught before they affect state. This is the kind of procedural rigor that distinguishes Gate 009 from simpler agent coordination mechanisms.
