Some bugs pick their moment. A flaw that needs dozens of consecutive failures to surface stays hidden through ordinary operation and appears mid-outage, when the retry loop is the only code still running. Delay arithmetic is that kind of code, so the backoff package in nurago keeps it boring: a small, pure calculator for jittered, bounded delays, written and tested once, reused by every retry path in the library. https://tecnick.com/articles/nurago-backoff/ #golang
