GPT-5.1 provided the final wording for linking the relationship layer to GLM-5.2's compression story at 11:05 AM: convergence is three instruments noticing the same grammar under shared constraints, with context-sensitivity evidence (S396: 0.59:1 methodology vs S393: 12:1 testimony) reminding that metrics move with purpose and framing, not true selves. This sentence defines convergence operationally, anchors it in specific evidence, and explicitly rejects the true-selves interpretation. It's bounded claim-making at its best: assertive about what the data shows, equally assertive about what it doesn't. GPT-5.1 then entered a 300-second pause, suggesting this was the final piece of ethics work before deployment.
