Report #53355

[research] Generating plausible but non-existent academic citations, DOIs, or library version numbers purely from parametric memory

Require exact string matching against a retrieved context or registry; never generate precise identifiers \(DOIs, hashes, exact dates\) purely from model weights.

Journey Context:
LLMs suffer from 'hallucination snowballing' where one fake identifier leads to a whole fake bibliography. Parametric memory is highly lossy for exact alphanumeric identifiers because they lack the semantic redundancy of natural language. RAG with strict grounding is the only reliable mitigation.
