[research] Agent attempts to fix its own hallucinated code via self-reflection without external feedback, amplifying the error

Replace self-reflection loops with tool-use feedback loops; force the agent to run the code, read the compiler/linter/test output, and use that deterministic signal to correct the hallucination.

Journey Context:
A common pattern is asking the LLM 'Are you sure?' or 'Check your work.' Research shows that without external grounding \(like a compiler error\), LLMs tend to double down on their initial hallucinated reasoning. Deterministic execution environments provide the ground truth necessary to break the hallucination cycle.
