One of the biggest misconceptions I see in software architecture is this: if two things represent the same business concept, they should share the same class.

Domain ownership is not just a management decision. It is an architectural one.

Giving all core domains to your best team sounds like the obvious choice. And in the short term, it probably is.

This repository is intentionally full of:
❌ Tight coupling
❌ Weak boundaries
❌ Misleading abstractions

Perfect for refactoring practice.

You can have great #Aggregates and well-defined #BoundedContexts and still miss an important modeling perspective.

#BusinessArchetypes help reveal recurring business patterns hidden behind domain concepts.

I love the idea of #SpecDrivenDevelopment: just write down all the requirements, explain the behavior, and an #AI agent will be able to implement it.

Fortunately, software engineering has never had a problem with incomplete requirements or stakeholders changing their minds. 😏

🏗️ Most software systems contain the same concepts: Products, Orders, Inventory, Contracts, Customers.

This repository shows how archetypes can be implemented using DDD and Ports & Adapters:

Not every architectural problem is technical debt.
Some costs are conscious trade-offs. Some are technical debt. Some are legacy created by years of evolution and missed decisions.
