The Zero-Drift API Series
Stop Trusting a Green Build You Can't Explain
There is a specific kind of production incident that hurts more than the others.
Not the kind where the stack trace is obvious. The kind where the build was green, the tests passed, and the code review looked clean, and yet something that used to work silently stopped working for a downstream team, a frontend client, or a mobile app. No alarm. No contract violation flagged. Just a broken assumption that traveled all the way to production dressed as a passing test.
That is the drift problem. And it is not a testing problem. It is a governance problem.
