The reproduction problem: why you can't recreate the investigative gap
In the modern dev stack, we have mastered the art of the deploy. We have CI/CD pipelines that ship code in minutes and observability dashboards that track every millisecond of latency. Yet, when a P0 incident strikes, the most common phrase in Slack isn’t a solution; it’s "I can’t reproduce this locally." This is the Reproduction Gap. Most engineering teams are world-class at building and monitoring, but they are remarkably fragile at recreating runtime behaviour.
