[architecture] Deciding between microservices and monolith for a startup/small team

Start with a Modular Monolith: enforce strict internal module boundaries \(ports/adapters\) but deploy as single unit; extract services only when a module's deployment cadence or scale requirements diverge significantly.

Journey Context:
Teams <10 often adopt microservices for 'clean architecture' but incur 5-10x operational load \(K8s, tracing, inter-service auth\) and impossible distributed debugging. Refactoring across service boundaries is prohibitively expensive. A modular monolith allows rapid refactoring while preserving option to extract later \(Strangler Fig pattern\). Extract only when independent deployment velocity outweighs coordination cost.
