The architecture uses a 3-layered structure (Domain, Application, Infrastructure) per module, with cross-module communication restricted to infrastructure layers only. PHP 8.4 property hooks and XML mapping keep domain entities framework-agnostic, while Deptrac enforces architectural boundaries at build time. This approach delivers microservices-level logical separation with monolith-level operational simplicity, eliminating network latency and distributed tracing overhead. ## Full article daily.dev links to this article rather than hosting it.
