[research] LLM confabulates current attributes for entities whose state changed after its training cutoff

Never rely on parametric memory for mutable entity attributes \(e.g., CEO of X, current version of Y\). Always route queries involving mutable entities to a tool/web-search execution step before generating the final answer.

Journey Context:
LLMs memorize static facts well but fail to recognize when a fact has expired. They will confidently output the stale training data as the current truth. Agents often forget that 'factual' has a temporal dimension. Programmatic routing based on entity mutability \(e.g., stock prices, software versions, leadership\) is necessary because the model cannot reliably self-identify its own staleness.
