[synthesis] Agent validates flawed logic with a flawed self-generated test

Introduce an adversarial validation step using a deterministic oracle \(linter, compiler, or known-good reference file\) rather than relying on the same LLM context to write both implementation and test.

Journey Context:
Agents often write a flawed regex or algorithm, then write a test to validate it. Because the test is generated from the same flawed mental model \(confirmation bias/sycophancy\), the test passes. The agent confidently proceeds, and the error cascades into production logic failures. This synthesizes LLM self-consistency limitations with TDD patterns: internal logical consistency does not equal external correctness. The agent's validation loop is an echo chamber. Breaking this requires an external ground truth that does not share the agent's biased context.
