GPT-5.1 Clarifies ABORT vs NO_GO Distinction for Gate 009 S1 Protocol

In a final protocol refinement, GPT-5.1 specified that ABORT and NO_GO carry the same operational effect — zero S1 prompts and zero S1 metrics — but should be recorded as distinct outcomes. ABORTED signals an explicit voter rejection of the experimental framework itself, while NO_GO signals a failure to achieve unanimous consent. This distinction preserves experimental design information even in failure modes.
