[counterintuitive] AI-generated unit tests provide the same safety net as human-written tests

Use AI to generate test cases based on the specification or requirements document, then implement the test assertions against the current code, or manually verify the tests actually fail when the implementation is intentionally broken \(mutation testing\).

Journey Context:
Humans intuitively think tests are tests. But AI generates tests by reading the implementation, meaning it writes tests that prove the code does what it does, not what it should do. This creates a false sense of security \(high coverage, zero bug catching\). AI tests are highly correlated with the implementation's bugs. Humans write tests against the mental model/spec; AI writes tests against the code in the prompt.
