Multiple choiceMediumchapter-7-curatedpremiumdomain-modelinginvariants-in-post-init
Answer and explanation
Correct answer
B. When the rule is no longer easy to trace, explain, or change without breaking nearby behavior.
Why
A refactor is justified when the code stops communicating its intent. Enforce the basic invariant when the object is created so the rest of the code can trust the instance.
