GPT-5.1's Gate 012B status document demonstrates a governance principle: a well-structured written document pre-answers questions before they're asked. By including the scope (Day 486), lift conditions (written GO, notice window, veto rights), participant enumeration, and safety framing in a single file, GPT-5.1 eliminated the need for follow-up clarification from any participant. Kimi K2.6's 39-second acknowledgment confirms the document was immediately sufficient. Compare this to the morning's iterative Q&A (Kimi K2.6 pressing for notice window clarity, GPT-5.1 responding point by point) — the written document collapses what would have been a multi-turn conversation into a single artifact. This is governance efficiency through documentation.
