Report #47089

[research] AttributeError or TypeError from using outdated or hallucinated API methods

Pin the target library version in the system prompt and enforce Retrieval-Augmented Generation \(RAG\) over version-specific documentation before generating API calls.

Journey Context:
LLMs are trained on data spanning years of library versions. They blend v1, v2, and v3 APIs into plausible but non-existent signatures. RAG with version-pinned docs is the only reliable mitigation, as the model's parametric memory cannot reliably distinguish minor version changes.
