[counterintuitive] Do AI-generated unit tests provide robust regression safety?

Provide the AI with the external specification or edge-case requirements to generate tests, and use mutation testing to verify the AI's tests actually catch defects.

Journey Context:
AI easily achieves high code coverage by generating tests that mirror the implementation logic, giving a false sense of security. The AI writes tests that pass on its own code, not tests that verify the specification. This results in high coverage metrics but low defect detection, as the tests will never fail if the implementation is wrong in the same way the AI's mental model was wrong when writing the test.
