APIs may create the appearance of modernization but without true modular design, hidden dependencies continue to limit agility and AI readiness.
In core banking architecture, modularization is often declared at the interface layer—and nowhere else.

Because modularization is not about how systems are accessed.
It’s about how they are structured.
