SafePyramid: A Hierarchical Benchmark for In-context Policy Guardrailing
Jiacheng Zhang, Haoyu He, Sen Zhang et al.
arXiv · 2026-06-29
SafePyramid is a new benchmark designed to evaluate how well AI guardrails can enforce application-specific safety policies provided as natural-language rules in context, rather than relying on fixed risk taxonomies. The benchmark includes 1,000 multi-turn conversations across 10 domains and 3,000 policies containing nearly 62,000 distinct rules, organized into three difficulty levels testing individual-rule understanding, rule-dependency reasoning, and adaptation to novel policy frameworks. Evaluating 10 frontier LLMs and 5 policy-configurable guardrails, the authors find that even the top model (GPT-5.5) correctly identifies all violated rules in only 54%, 35.3%, and 12.9% of cases at the three difficulty levels, demonstrating that in-context policy guardrailing remains a largely unsolved problem. These findings highlight significant gaps in current guardrail systems and motivate the development of more reliable, policy-adaptive safety mechanisms for real-world AI deployments.

How Far Can You Get Without a GPU? A Systematic Benchmark of Lightweight Hallucination Detection Across Question Answering, Dialogue, and Summarisation
Kriti Faujdar, Smit Kadvani
arXiv · 2026-06-29
This paper systematically benchmarks five lightweight, CPU-feasible hallucination detection methods—ROUGE-L, semantic similarity, BERTScore, an NLI detector using a FEVER-trained DeBERTa model, and a score-level ensemble—against the HaluEval benchmark across question answering, dialogue, and summarisation tasks. Evaluated on 2,000 test instances per task, the ensemble achieves F1=0.792 and AUC-ROC=0.873 on QA, the NLI detector leads on dialogue (AUC-ROC=0.713), but all methods collapse to near-random performance on summarisation (AUC-ROC 0.469–0.574). The findings reveal that hallucination detection performance is highly task-dependent and that summarisation represents a systematic failure point for GPU-free approaches. This provides practical guidance for resource-constrained teams seeking to deploy trustworthy AI without GPU infrastructure or proprietary API access.

HERO: Improving the Reliability and Sensitivity of Generative Model Evaluation Using Historical Data
Xinrui Ruan, Zhenyu Zhao, Waverly Wei et al.
arXiv · 2026-06-29
HERO (History Enhanced RObust model evaluation) is a statistical framework that improves the reliability and sensitivity of generative AI model evaluation by leveraging historical annotation data. Because gold-standard human labels are expensive and scarce, organizations often rely on noisy 'silver' labels from crowdsourced or vendor annotators, which can introduce bias and high variance into performance estimates. HERO addresses this by calibrating silver labelers' reliability using historical gold annotations and anchoring estimates to high-precision covariate information from past evaluation rounds, reducing both bias and variance. The authors establish theoretical conditions for these improvements, validate them in simulation studies, and demonstrate effectiveness on real-world model evaluation benchmarking datasets.

Adoption of Artificial Intelligence and Human Resource Upskilling in Emerging Markets: Evidence from Small and Medium Enterprises in Oyo State, Nigeria
Dauda Adewole Oladejo, Grace Oluwatoyin Obadare, Oluwatobiloba Joshua Olayemi
ACTA ECONOMICA · 2026-06-29
This study examines how AI adoption is associated with workforce upskilling in small and medium-sized enterprises (SMEs) in Oyo State, Nigeria, surveying 135 HR professionals, SME operators, and employees across approximately 72 firms. Results show that while AI integration in HR practices remains nascent (mean score of 2.116), key AI adoption dimensions—including organisational integration, AI training programmes, and data-driven decision-making support—are significantly and positively correlated with employee skill enhancement (R=0.750, R²=0.562, p<0.001). Major barriers include infrastructure gaps, educational deficiencies, policy shortfalls, and socio-cultural resistance. The findings highlight both the potential and the structural challenges of deploying AI for human capital development in emerging market contexts.

AI-Assisted Devices in University Written Examinations: A Structural Threat to the Degree as a Warrant of Competence
Demetrios Venetsanos
Preprints.org · 2026-06-29
This paper argues that the convergence of miniaturized cameras, AI smart glasses, and large language models creates a 'cheating pipeline' that can compromise closed-book university examinations in a structurally undetectable way. Drawing on a narrative review of academic integrity literature (1966–2025), UK Ofqual malpractice statistics (2019–2025), and a scan of commercially available AI-assisted devices, the authors find that covert device use in invigilated exams is already increasing in secondary education, with conditions plausibly extending to higher education. The core argument is not merely about individual cheating but about a certification crisis: if a machine can silently supply answers, the degree can no longer reliably warrant the competence of its holder for the cohort as a whole. The paper calls for institutional reconsideration of examination design and what degrees certify in an era of ambient AI.

Artificial Intelligence in United States Enterprises: An Integrative Review of Adoption Patterns, Sectoral Applications, and Organizational Outcomes
Gustavo Jardim Alves
Journal of Engineering Research · 2026-06-29
This integrative review synthesizes peer-reviewed research, government statistics, and industry surveys through early 2026 to assess how AI is actually adopted and used across U.S. enterprises. It finds a sharp split between self-reported adoption rates (above three-quarters of organizations) and production-grade deployment (high single digits to roughly one-fifth when weighted by employment), with real deployments concentrated in customer service, marketing, software engineering, financial risk management, healthcare, and factory quality control. Field experiments consistently show double-digit productivity gains, disproportionately benefiting less-experienced workers, yet most firms report no profit impact—a gap the authors explain through general-purpose-technology theory and the complementary-intangibles hypothesis. The findings carry implications for managers, policymakers, and researchers navigating an unsettled U.S. AI governance landscape.

DOES SIZE MATTER? A COMPARATIVE STUDY ON AI’S INFLUENCE ON EMPLOYEE TRAINING, BUSINESS EFFICIENCY, AND COMPETITIVE PRESSURE
Enikő Korcsmáros, Aranka Boros, Klaudia Balázs
Management Theory and Studies for Rural Business and Infrastructure Development · 2026-06-29
This study of 269 private-sector firms in Hungary and Slovakia finds that company size is positively associated with AI adoption, employee upskilling investment, and efficiency gains, with micro and small firms facing the greatest resource barriers. Medium-sized firms occupy an intermediate position, while larger enterprises are better positioned to convert AI into training and productivity benefits. Notably, no significant link was found between company size and perceived competitive disadvantage from AI, suggesting industry-level factors may matter more. The findings point to a need for targeted policy support for smaller enterprises and strategic workforce planning in larger ones.

The preparation gap: IHL, human–machine teaming and assurance in military AI systems
Sahr Muhammedally
International Review of the Red Cross · 2026-06-29
This paper examines how AI systems used in military targeting, intelligence analysis, and operational planning must be governed before hostilities occur rather than assessed only after deployment. The authors argue that risks such as automation bias and adversarial manipulation threaten compliance with international humanitarian law (IHL) in human-machine teaming (HMT) contexts. To address this, the paper proposes an 'HMT Assurance Card,' a cross-disciplinary lifecycle instrument that integrates IHL obligations, civilian harm pattern analysis, and AI governance frameworks into measurable standards applicable across defense institutions and coalition environments. The work is relevant to certification and policy communities seeking structured pre-deployment assurance mechanisms for high-stakes AI systems.

A Model Proposal For Quality Assurance in Higher Education: The Explainable Quality Assurance Model
Hakan Kurt
Üniversite Araştırmaları Dergisi · 2026-06-29
This paper proposes a seven-component Explainable Quality Assurance (XQA) model for higher education institutions, arguing that AI-driven quality assurance must prioritize explainability, human oversight, and institutional legitimacy—not just speed and efficiency. The model's core principles include data transparency, indicator justification, algorithmic traceability, contextuality, ethical compliance, and contestability. The study evaluates Turkey's Higher Education Quality Council (THEQC/YÖKAK) against international frameworks including ESG 2015, UNESCO generative AI guidance, NIST's explainable AI approach, ENQA guidance, and the EU AI Act. It concludes that the future of AI-supported quality assurance lies in auditable, humanly balanced algorithmic governance rather than technical automation alone.

Quantitative and Qualitative Implications of AI Adoption for HRM in Last-Mile E-Commerce Delivery: A Systematic Review
Ionel Bostan, Alunica Morariu, Cristina Lazăr
Journal of East European Management Studies · 2026-06-29
This systematic review of 200 studies (2013–2025) examines how AI adoption in last-mile e-commerce delivery affects both operations and human resource management. It finds substantial operational gains—including improvements in delivery speed (15–32%), cost savings (8–25%), fleet utilization (10–18%), and workforce-allocation accuracy (12–20%)—alongside qualitative challenges such as job redesign, surveillance pressures, and workplace inclusion concerns. The authors propose an integrated HRM-logistics framework emphasizing human-centered AI adoption, transparent performance metrics, and workforce upskilling. Policymakers are urged to develop context-sensitive governance to balance efficiency gains with employee well-being.

Vectored Conversational AI Testing
William Argo
Zenodo (CERN European Organization for Nuclear Research) · 2026-06-29
This paper introduces Vectored Conversational AI Testing, a dynamic testing methodology that treats conversation as a behavioral surface to reveal how AI systems adapt, stabilize, or degrade over the course of an interaction. Unlike static prompt-based testing, the approach is designed to expose emergent behaviors such as behavioral drift, reasoning breakdowns, and boundary-handling failures in real or near-real conversational conditions. The framework produces behavioral evidence intended to support evaluation, safety analysis, risk management, and compliance workflows, making it relevant to AI assurance and auditing practices.

Budgeted Act-or-Defer Multi-Agent LLM Deliberation with Local Reliability Bounds
Mengdie Flora Wang, Haochen Xie, Guanghui Wang et al.
arXiv · 2026-06-28
This paper addresses the challenge of knowing when a multi-agent LLM deliberation system is reliable enough to act autonomously versus when it should escalate to human review. The authors formulate this as a 'budgeted act-or-defer' problem, using k-nearest-neighbor confidence bounds on calibration data to certify correctness before acting, with the reliability guarantee decomposed into calibration failure, residual action risk, and representation gap components. On six benchmarks against nine baselines, the method uses only 9–12% of the pre-declared wrong-action budget on activated datasets, achieving up to 84% automation and 96% acted-on accuracy, while appropriately deferring on stress-test datasets. This matters for enterprise and quality-assurance contexts because it provides an auditable, prospective mechanism for translating a user-declared error budget into a deployment operating point, rather than relying on post-hoc threshold tuning.

Resolution Thresholds in VLM Detection of Harmful ASCII Art Across Construction Modes and Languages
Yikai Hua, Peter West
arXiv · 2026-06-28
This paper investigates how image resolution affects the ability of large Vision-Language Models (VLMs) to detect harmful content encoded as ASCII art, a known jailbreak technique that can bypass content moderation systems. The researchers evaluate eight state-of-the-art VLMs on English and Chinese ASCII art generated across eight character construction modes and ten resolution scales. Results show that detection rates decline sharply above certain resolution thresholds, with word-based construction modes being the most resistant to detection across the full resolution range. The findings expose a systematic vulnerability in VLM-based moderation and motivate the development of resolution-aware evaluation standards.

How much of an LLM-generated clinical corpus is actually new? A production-scale measurement of content redundancy for provenance classification
Ali H. Lazem, William J. Teahan
arXiv · 2026-06-28
This paper investigates whether the sheer volume of LLM-generated clinical training corpora actually reflects their information content. Analyzing 2.51 billion tokens produced by a multi-agent clinical extraction pipeline applied to 167,034 patient narratives, the authors find that only 10.9% of the output is trainable-unique content while 79.4% is redundant—meaning raw token count overstates information content by roughly ninefold. The redundancy distorts training distributions by over-representing longer, more complex cases, and in downstream tests, de-duplicating the corpus before model adaptation measurably improved clinical disease-recognition performance at equal token budget. The authors release a provenance-based classification tool openly, offering a practical method for auditing and improving LLM-generated medical datasets.

The Joint Effect of Quantization and Sampling Temperature on LLM Safety Alignment: A Factorial Analysis
Hari Prasad, Ritam Pal
arXiv · 2026-06-28
This paper investigates how combining model quantization (reducing numerical precision) with higher sampling temperatures affects the safety alignment of large language models (LLMs). Testing 8 instruction-tuned models across 144 configurations on 7 harmfulness benchmarks and roughly 2 million responses, the authors find that standard INT4/INT8 quantization is largely safety-neutral — attack success rates stay within ~1.6 percentage points of full-precision FP16 for 7 of 8 models. The greater risk comes from higher sampling temperatures, which sharply increase decision instability (up to 41.9% decision flip rate at T=1.0), and the two factors do not compound. The study recommends that safety evaluations report multi-sample stability across multiple benchmarks rather than relying on single-benchmark, greedy-decoding results.

MAM-AI: An On-Device Medical Retrieval-Augmented Generation System for Nurses and Midwives in Zanzibar
Yi Ren
arXiv · 2026-06-28
MAM-AI is an offline medical question-answering system designed for nurse-midwives in Zanzibar, running entirely on a commodity Android device using a 300M embedding model and a 4-billion-parameter quantized language model to retrieve answers from 87 curated guideline documents covering 63,650 passages. The system addresses the challenge of intermittent connectivity and limited access to authoritative clinical guidance at the point of care in a region with high maternal and newborn mortality. Evaluation using LLM judges validated against physician rubrics found that on-device retrieval performs comparably to cloud systems, but the small generator struggles to be both helpful and safe simultaneously; the deployed model prioritizes safety and faithfulness, with prompt engineering reducing unhelpful deflections from 33% to 3%. The authors release the system, knowledge base, benchmarks, and evaluation harness as an open-source research prototype, not a production product.

Proteus: Automated Adversarial Robustness Testing for Audio Deepfake Detectors
Nicolas M. Müller, Aditya Tirumala Bukkapatnam, Zohaib Ahmed
arXiv · 2026-06-28
Proteus is a framework from Resemble AI that automatically tests the robustness of audio deepfake detection systems by searching for sequences of common audio transformations—such as codec transcoding, noise addition, reverberation, compression, and VoIP simulation—that can fool a detector while keeping speech quality intact. The system uses two complementary strategies: an exhaustive breadth-first search and a Q-learning agent that finds longer, more complex attack chains. Deployed continuously against a production detector, Proteus found that specific augmentation chains can reliably reverse detection verdicts without degrading speech intelligibility or speaker identity. These findings are then used to retrain and harden the detector, making it a practical tool for ongoing quality assurance in deepfake detection pipelines.

Em-ergence of the em-dash: a population-level rise in em-dash frequency in medRxiv preprints at the dawn of the large-language-model era
Przemysław Czuma
arXiv · 2026-06-28
This pre-registered study tracked em-dash usage across 69,632 medRxiv preprints from 2020 to 2025 to test whether LLM-assisted writing has left measurable stylistic traces in the scientific literature. Em-dash prevalence in Discussion sections rose from 4.23% before ChatGPT's launch to 11.58% afterward—an increase of 7.35 percentage points (95% CI 6.94–7.77; odds ratio 2.96)—with the trend accelerating gradually rather than as an abrupt shift. The effect held across all sensitivity analyses and was not observed in a placebo pre-LLM split (+0.13 pp) or in boilerplate sections, and was corroborated by other LLM-associated lexical markers. The authors caution that the em-dash is a population-level signal rather than a per-paper detector, and that the design cannot establish causality, but the findings indicate that how scientific preprints are written changed materially in the early 2020s.

Deterministic Decisions for High-Stakes AI. A Zero-Egress Pipeline with the Deployability of RAG and the Accuracy of Machine Learning
Craig Atkinson
arXiv · 2026-06-28
This paper identifies 'intervention bias' as a failure mode in zero-shot LLM-based educational advisory systems, where models recommend unnecessary student interventions far more often than an optimal oracle policy would. Testing on the Open University Learning Analytics Dataset (800 students), zero-shot GPT-4o falsely recommended action for 73% of students when only 29.9% actually needed it — a 43 percentage-point false-positive rate that would translate to roughly 4,300 unnecessary advisor contacts per 10,000 students per cycle. Supervised alternatives — an ONNX Decision Transformer and an XGBoost classifier — both eliminate this bias, with the Decision Transformer achieving macro-F1 of 0.79 and sub-5ms CPU latency. The paper also exposes an 'Evaluation Gap' where LLM-as-judge scoring tools are blind to intervention bias, rewarding fluent but over-prescriptive responses rather than correct decisions.

Manufactured Confidence: How Memory Consolidation Turns Hearsay into Confident Facts
Alex Kwon
arXiv · 2026-06-28
This paper investigates how LLM agent memory systems—such as mem0 and LangMem—introduce a dangerous failure mode by rewriting hedged, uncertain statements into confident, flat assertions stored as trusted facts. The authors show that agents then act on these manufactured-confident memories as if they were verified, granting above-clearance requests without any external attacker involved. Crucially, the vulnerability lies in phrasing confidence rather than source attribution: flat assertions are obeyed while hedges are discounted, and even evidentially-marked language like 'reportedly' is treated as authoritative on most models. The paper identifies that relying on a single stored memory is the core hazard and finds that adding one redundant source restores correct decision-making.

When Summaries Distort Decisions: Information Fidelity in LLM-Compressed Financial Analysis
Hoyoung Lee, Suhwan Park, Seunghan Lee et al.
arXiv · 2026-06-28
This paper investigates 'information fidelity' in large language model (LLM)-based compression of financial documents such as filings and earnings-call transcripts, finding that compressed summaries can be fluent and factually plausible yet still alter the investment judgments that the original source would support. The authors identify two diagnostic failure patterns: decontextualization (salient evidence separated from necessary caveats) and model dependency (different compressors producing different views of the same source). They propose 'Agentic Context Compression,' which generates multiple candidate compressions and audits their disagreements against the original source to reduce fidelity loss. The work argues that financial compression pipelines should be evaluated not only for efficiency or factual accuracy but also for their ability to preserve decision-relevant context, with implications for enterprise AI systems and the quality of AI-assisted financial analysis.

PolicyGuard: A Dialogue-Grounded Sub-Agent Verifier for Policy Adherence in LLM Agents
Seongjae Kang, Taehyung Yu, Sung Ju Hwang
arXiv · 2026-06-28
PolicyGuard introduces a sub-agent verifier for large language model (LLM) agents that monitors full multi-turn conversations to ensure agent actions comply with organizational policies stated in system prompts. Unlike prior safeguarding approaches that check individual argument values, PolicyGuard reasons over the entire dialogue context and provides actionable, conversation-specific feedback to guide the agent's next turn. Tested on the tau^2-BENCH airline benchmark across three vendors (GPT-5.4, Claude Sonnet 4.6, Gemini 2.5 Pro), PolicyGuard improves PASS4 scores by +12.0, +6.0, and +12.0 percentage points respectively, while achieving higher policy-violation recall and blocking roughly half as often as argument-level guards. This work matters for enterprise deployments where LLM agents must reliably follow company policy across complex, multi-turn workflows.

Direct Causation in International Humanitarian Law and the Challenge of AI-Mediated Civilian Cyber Operations
Alice Saito, Harold Godsoe, Phan Xuan Tan
arXiv · 2026-06-28
This paper examines how international humanitarian law (IHL) — specifically the ICRC's 2009 Interpretive Guidance on direct participation in hostilities — fails to adequately address civilian use of autonomous multi-agent AI cyber systems. The authors argue that when a civilian deploys such a system, the 'one causal step' standard for direct causation breaks down because harm results from system-generated decisions made after the human has disengaged, and the 'integral-part' requirement cannot extend to AI-generated actions as it presupposes identifiable human contributors. The paper proposes classifying AI-mediated operations along a five-level spectrum based on goal-specification granularity, and finds that existing AI governance instruments do not capture or report this property. The analysis concludes that current IHL frameworks default to treating such deployments as indirect participation, undermining the law's purpose of holding accountable civilians who personally take part in hostilities.

Agent Security Meets Regulatory Reality -- A Practitioner Systematization of Autonomous-Agent Threats and Controls in Regulated Financial Systems
Krishna Mohan, Guda Nagavenkata Srinivasa
arXiv · 2026-06-28
This paper bridges the gap between academic AI agent security research and real-world regulated financial deployments by mapping six established agentic threat categories—prompt injection, identity and authorization, action auditability, tool abuse, data residency, and boundary policy enforcement—onto specific US and EU regulatory obligations including ECOA, the EU AI Act, GDPR Article 22, and FINRA's 2026 agent guidance. Drawing on production experience with a Know Your Customer deployment for a consumer credit product, the authors document four architectural patterns that moved a multi-day manual process to same-day automated resolution for roughly four in five cases. They also report three negative results, including two control failures discovered only through internal audit and a population of legitimate applicants the automated pipeline cannot serve. The paper concludes that securing agents under regulation is primarily about making auditability, least-privilege authorization, and boundary policy enforcement work at production scale—gaps that current agent frameworks leave for deploying engineers to solve.
