Report #16205

[research] Inventing non-existent methods, classes, or parameters for real libraries

Ground API calls strictly in retrieved, version-pinned documentation rather than relying on parametric memory; use static analysis or linting to validate signatures against the actual installed library before execution.

Journey Context:
LLMs blend training data across library versions, resulting in 'API mixing' \(e.g., using a PyTorch method in a TensorFlow script, or passing a kwarg that was removed in v2.0\). Parametric memory is lossy for exact API signatures. RAG over specific version docs is the only reliable mitigation for this class of hallucination.
