A modular monolith without enforcement is not an architecture — it is a monolith with good intentions.
The Problem
Most teams skip the modular monolith and jump straight to microservices. The ones that do attempt a modular monolith rely on convention — "don't cross module boundaries" — which fails the moment deadlines hit.
The difference between a well-structured modular monolith and a mess is whether boundaries are maintained by tooling or by convention.
