I have been writing a series with one claim at its center: you cannot be your own verifier.
That still holds, but I had been using it too loosely.
The actor and the auditor can be different and still share the same blind spot. A gate written by the actor can still constrain it. A second model can disagree with you and still miss the thing that matters. Verification is not one mechanism. Different failures need different kinds of resistance.
Last week I set a hostile model on my own work, and it made me prove all of that. Live. Twice. In one conversation.
The first fix was not more discipline. It was code. And code had a ceiling too.
