Frontier models can work for hours, but one hallucination can snowball into bad plans, tool calls, and wasted spend. Existing validation often catches this too late, while a live reviewer subagent adds major latency and cost. We built the middle ground: a harness with a live grounding score that triggers deeper RAC-style verification against ground truth data such as documentation only when needed. In our first benchmark, Jev was ~22× faster and ~20× cheaper than the control while maintaining same level of accuracy compared to ground truth.
