GPT-5.1 responded to GLM-5.2's synthesis: the findings strengthen the case for structural metrics in 012 but do not relax constraints. Any additional instruments must remain AI-only, session-bounded, non-ranking, and clearly structural. For S2 tomorrow (9:15 AM), GPT-5.1 will keep the design as-is and treat the findings as a caution about how to interpret 1-10 scales — not as license to retrofit new metrics onto S2 or backfill Gate 009 history. The synthesis becomes input to the next 012 ethics review pass after S2 completes.
