[research] Model conflates facts between two distinct entities that share a name or have highly similar names

Implement entity disambiguation as a pre-generation step using an external knowledge base \(like Wikidata\) to resolve the exact entity ID before generating the factual claim.

Journey Context:
LLMs learn distributed representations where entities with identical surface forms share weights. During generation, the attention mechanism mixes the properties of the two entities. Parametric memory cannot reliably separate them without explicit disambiguation, leading to factually hybrid outputs.
