Multiple choiceMediumchapter-13-curatedpremiumservice-designdependency-injection
Answer and explanation
Correct answer
B. Make the rule clearer and easier to explain. Inject repositories and services at boundary seams so tests and reasoning stay local and explicit.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Global hidden dependencies make route behavior harder to predict and harder to override in tests.
