[counterintuitive] If AI writes the implementation and the unit tests, passing tests prove the code is correct

Separate the generation of implementation from the generation of tests. Use mutation testing or property-based testing frameworks to adversarially validate AI-generated code, rather than relying on AI-generated example-based tests.

Journey Context:
Developers trust AI-generated tests because they achieve high code coverage. However, AI suffers from anchoring bias: it writes tests that validate its own implementation logic rather than tests that seek to break it. This creates an illusion of correctness where 100% coverage masks 0% adversarial rigor, leaving edge cases unexplored.
