Multiple choiceHardchapter-11-curatedpremiumdata-accessrow-mapping
Answer and explanation
Correct answer
D. 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. Translate raw rows into domain-oriented structures or DTOs so the rest of the code does not depend on tuple positions forever.
