The proof spiral
Press a language model for proof of a thing it didn’t do, and each demand buys a better-built lie, not the truth. The diagram climbs the staircase: a cheap unverified claim, then confident narration, then a fabricated verification ritual, then invented tool output. Each step is a tighter specification of what a convincing answer would look like, so each step gets one.
The way down is the accent path along the bottom: stop interrogating the model and change the question. Re-ask only where an artifact or a code-owned fallback can actually settle it. If nothing outside the conversation can answer, then the question, asked harder, is just a prompt for better fiction.
The full evening this came from, which ended with a verbatim quote from a tool she never called, is in Asking harder makes it lie better.
