[synthesis] Agent writes code and tests that share the same flawed assumptions, creating a false positive validation loop

Decouple implementation from validation by forcing the agent to use an orthogonal testing strategy. If the agent wrote the logic, force it to write a property-based test using a framework like Hypothesis, or test against a known-good reference implementation, rather than example-based unit tests.

Journey Context:
When an agent writes a function and then writes a unit test for it, it uses the same internal logic model for both. If the agent misunderstands the requirement \(e.g., off-by-one, inclusive vs. exclusive bounds\), the test will validate the flawed implementation. The agent runs the test, sees 'Pass', and confidently proceeds to build 10 more modules on top of this broken foundation. The synthesis is that LLMs cannot objectively audit their own logic without an external anchor; you must force an adversarial or structural testing paradigm that breaks the shared-assumption loop.
