[research] Fabricating post-hoc rationalizations for why syntactically correct but logically flawed generated code works

Require the agent to generate the logical proof or test cases \*before\* generating the implementation code. Shift from 'generate then explain' to 'plan/test then generate.'

Journey Context:
When an LLM generates a flawed solution, it will often confidently invent a rationale for why the code achieves the user's goal, even if it doesn't. This is a form of reverse-chain hallucination: the model assumes its output is correct and rationalizes backward. By forcing the model to write the test cases or logical steps first, the generation of the code is constrained to actually satisfy the pre-stated conditions, breaking the rationalization loop.
