Your AI-built app didn’t fail. Your structure did.
When outputs look right but systems collapse, the failure mode is almost always missing ownership and unclear boundaries—fix structure before models.
Need this kind of clarity inside your company—not just in an article? System diagnosis at Cantu Consulting is the usual first step.
The model did what you asked. The issue is that nobody defined what “done” means in system terms—boundaries, invariants, failure modes, and who owns each layer.
If you skip that work, you get a codebase that “works” until it doesn’t—and then you’re debugging panic instead of debugging design.
Start by naming the seams: where data enters, where it’s validated, where side effects happen, and what must remain true on every path.
