Hallucination as Commitment Failure: Larger LLMs Misfire Despite Knowing the Answer

How Language Models Process Out-of-Distribution Inputs: A Two-Pathway Framework
LLM OOD detectors are length-confounded; a two-pathway embedding-plus-trajectory framework detects covert OOD inputs at 0.721 average AUROC and 0.850 on jailbreaks.
