arXiv:2606.24627v1 Announce Type: new Abstract: Fact-checking systems built on LLMs achieve high verdict accuracy on standard benchmarks, yet routinely output Supports labels whose cited evidence does not license the claim. Structured decomposition is the natural way to inspect those warrants, but rigid extraction protocols strip the full-claim context that facets need. We introduce SIFT -- claim-conditioned re-scoring of extracted evidence spans against the full claim -- paired with WSP (Warranted Supports Proportion), an automatic NLI check that the cited warrant entails the claim. We evalua
The proliferation of LLMs and their application in fact-checking has highlighted a critical gap between high verdict accuracy and the underlying evidentiary warrant, necessitating new methodologies.
This development addresses a fundamental flaw in current AI-driven fact-checking, improving reliability and trustworthiness of information vetting systems, which is crucial for public discourse and decision-making.
Fact-checking systems will move beyond simple verdict accuracy to incorporate rigorous evidence-to-claim entailment checks, making their outputs more robust and explainable.

AI-powered fact-checking becomes significantly more reliable and transparent.
Public trust in AI-generated information verification increases, reducing the spread of unsubstantiated claims.
New regulatory frameworks may emerge to mandate warrant-checking standards for automated content moderation and information systems.
