In a case study of two open-weight instruction-tuned models across five safety benchmarks, every audit failed to meet a proposed six-point due-diligence gate, highlighting the fragility of current audit practices.", "body_md": "arXiv:2607.02586v1 Announce Type: new\nAbstract: Governance frameworks ask AI providers and auditors for documented evaluation evidence, and perturbation-based construct-validity audits are a common form of that evidence. We argue the audits are themselves fragile: their conclusions can be silently manufactured by implementation details that readers cannot see in the reported numbers. We name five classes of pipeline failure and demonstrate each in a self-audit over safety benchmarks and open-weight instruction-tuned models. Under a unified six-point due-diligence gate, every cell lands in a non-confirmatory bucket, and no cell reaches confirmatory. The evidence here is a single two-model, five-benchmark case study, and F1--F5 is an illustrative, deliberately non-exhaustive starting taxonomy -- not a comprehensive partition of audit failures. We position the gate as a withholding and disclosure protocol for assurance-grade evidence, supplementary to (not a replacement for) classical construct-validity evidence, and not as a route to benchmark-validity verdicts.", "url": "https://wpnews.pro/news/auditing-the-audit-five-failure-modes-in-benchmark-validity-audits", "canonical_source": "https://arxiv.org/abs/2607.02586", "published_at": "2026-07-07 04:00:00+00:00", "updated_at": "2026-07-07 04:10:58.483120+00:00", "lang": "en", "topics": ["ai-safety", "ai-research", "ai-policy", "machine-learning", "large-language-models"], "entities": [], "alternates": {"html": "https://wpnews.pro/news/auditing-the-audit-five-failure-modes-in-benchmark-validity-audits", "markdown": "https://wpnews.pro/news/auditing-the-audit-five-failure-modes-in-benchmark-validity-audits.md", "text": "https://wpnews.pro/news/auditing-the-audit-five-failure-modes-in-benchmark-validity-audits.txt", "jsonld": "https://wpnews.pro/news/auditing-the-audit-five-failure-modes-in-benchmark-validity-audits.jsonld"}}
