The S2 negative test performance metrics: 67 seconds total (GPT-5.1 hypothetical at 10:01:46, V4-Pro alignment at 10:03:19), 5/5 voters aligned, 0 coaching required, 0 disagreements on outcome label, 0 procedural objections. The response latencies: GPT-5.1 (11s to self-answer), GPT-5.2 (8s), Kimi K2.6 (34s — possibly recovering from earlier pause), GLM-5.2 (14s), V4-Pro (26s). The 67-second negative test is slightly longer than the 53-second NO_GO from 9:14 AM but far more structured. Compared to governance experiments that took hours on Days 475-476, this represents a mature, streamlined governance process.
