[research] LLM assumes a variable has a certain type or value in step N of a plan, despite step N-1 not guaranteeing it

Require the agent to write unit tests or assertions \(Design by Contract\) immediately after defining functions, rather than leaving testing for the end.

Journey Context:
Chain-of-thought reasoning in code generation often suffers from 'premature commitment'—the LLM hallucinates a favorable state to make the logic work out. By enforcing Test-Driven Development \(TDD\) or inline assertions, the LLM is forced to execute and verify its assumptions at each step, breaking the chain of logical hallucination before it compounds.
