Domain Service
A controlled Domain Service pattern for maintainable systems.
Use Domain Service when it directly addresses system complexity; do not introduce it without a concrete design need.
When to use it
Apply where the pattern creates an explicit boundary, invariant or operational benefit.
Advantages
Improves clarity and makes responsibilities testable.
Tradeoffs
Adds abstraction and must remain proportionate to the system.
