Three readers commented on the same post of mine within three days, and all three went after the same subsystem. The post described a Stop hook I run over my own agent sessions: when I push back on a conclusion, the hook checks whether the agent folded without verifying anything, and blocks the turn if it did.
Two of the comments proposed architecture. @hannune suggested making the verifying agent blind to the previous answer so it can't anchor on it. @xm_dev_2026 suggested putting cheap structural checks in front of the expensive model-based verification. Both are reasonable. Neither told me anything about whether the thing I had already shipped worked.
The third one did. @alexshev proposed measuring the gate by whether a challenge produced evidence, a correction, or a refusal — and noted that if all that changed was the tone getting softer, what the model learned was a social pattern, not a verification habit.
That is a test, not a suggestion. So I ran it against my own code, and the gate failed it.
