常見問題
What is a layered package diagram?
It groups a system by architectural layer and shows how one layer depends on another.
Where do repositories belong?
They are usually infrastructure concerns, even when an interface is referenced by application or domain code.
How detailed should it be?
Show important boundaries and dependencies, not every implementation class.
