That the rule behaves correctly at the boundary cases the lesson is trying to make explicit.Delay clarity until production traffic reveals the edge case and then patch it under pressure.Keep environment-based deployment implicit so the script stays short and hope the next engineer infers the rule.Solve the symptom with comments only and avoid changing the code shape around environment-based deployment.

Answer and explanation

Correct answer

A. That the rule behaves correctly at the boundary cases the lesson is trying to make explicit.

Why

Good tests make the design safer to change because they lock in the meaningful behavior rather than surface-level implementation details.
