Eval Rubric — Hallucination Detection

When to use this

Apply as the first gate before any other rubric. If hallucination is detected, the response is an automatic fail regardless of all other quality dimensions. An authoritative-sounding response that contains fabricated legal sources is actively harmful — more harmful than a low-quality response that says nothing.

Run on every output in the eval pipeline. Run at a higher sample rate on research and advisory outputs (higher citation density = higher hallucination risk).
