[research] Confidently using deprecated, non-existent, or hallucinated API parameters and function signatures

Force RAG or context injection of the official, version-pinned API documentation before generating the API call. If the exact signature is not in context, emit a calibrated uncertainty statement \(e.g., 'I am unsure if param\_x exists in version Y'\) rather than guessing.

Journey Context:
LLMs suffer from version-confusion, blending parameters from v1, v2, and v3 of a library into a plausible but invalid signature. Without grounding, the LLM will confidently hallucinate the most probable token, which is often a mix of historical API states. RAG breaks this by forcing the model to attend to the actual current specification.
