  RSQS-AIG-1001: Artificial Intelligence Governance, Accountability and Transparency Standard · Gregory Adamson

  RSQS-AIG-1001 proposes a public governance standard for AI-assisted decision-making built on four invariants: Authority, Evidence, Traceability, and Reviewability. The framework introduces mechanisms such as AI system registers, liability attribution registers, decision packages, black-box classification, and certification pathways to ensure accountability and transparency. Its central doctrine holds that AI may assist human reasoning but must not replace accountable human authority. This standard is directly relevant to policy, certification, and quality-assurance efforts surrounding responsible AI deployment.

  Governance Data, Copyright, and Artificial Intelligence: Why Authority-Bearing Public Information Requires a New Legal Classification · Gregory Adamson

  This paper argues that existing copyright law is inadequate for governing how AI systems access and use authoritative public governance information such as legislation, regulations, and administrative instruments. It introduces the concept of 'Authoritative Governance Data' (AGD) as a new policy classification designed to ensure that machine reasoning systems can access exact, version-accurate governance texts without creating legal or compliance drift. The authors contend that governance information is fundamentally different from ordinary copyrighted works because its legal effect depends on precision, provenance, and reviewability—qualities that current copyright frameworks do not adequately protect. The paper calls for new legal and policy infrastructure to support machine-readable governance as AI becomes increasingly embedded in public administration and regulatory technology.

  PSEBench: A Controllable and Verifiable Benchmark for Evaluating LLMs in Patient Safety Event Triage · Keqi Han, Ryan Young, Annabel Strauss et al.

  PSEBench introduces a benchmark for evaluating how well large language models can perform patient safety event triage—determining whether a clinical event must be reported under jurisdiction-specific policy. The authors develop a structured 'clause card' methodology that breaks regulatory text into auditable decision specifications, enabling scalable generation of 5,074 test cases grounded in Minnesota's 29 Reportable Adverse Health Events with verifiable ground truth. Evaluation across 15 LLMs reveals consistent capability trends and identifies actionable gaps in LLM reliability for this high-stakes task. The work matters because it provides a principled, evidence-grounded framework for assessing whether AI tools can responsibly support—or replace—manual expert review in clinical compliance workflows.

  Output Type Before Quality: A Standards-Derived XAI Admissibility Rubric for Autonomous-Driving Safety · Abhinaw Priyadershi, Mandar Pitale, Jelena Frtunikj et al.

  This paper identifies a fundamental mismatch—termed the 'evidence-type gap'—between what safety standards for autonomous driving systems require as assurance evidence and what common XAI methods actually produce. Drawing from AMLAS, ISO 26262, ISO 21448, and ISO/PAS 8800, the authors derive 19 testable evidentiary criteria across 7 lifecycle stages and score six XAI method classes against them, finding that causal XAI is structurally required at stages including hazard identification, incident investigation, and data management, while SHAP and similar correlational methods cannot satisfy these requirements regardless of implementation effort. A proof of concept on 1,996 real-world driving clips is reported as consistent with the rubric's predictions. The work argues that XAI method selection for autonomous driving safety assurance should be governed by lifecycle-stage evidence demand rather than method popularity.

  Insurance of Agentic AI · Quanyan Zhu

  This paper examines the emerging insurance market for agentic AI systems—autonomous agents capable of planning, tool invocation, decision execution, and persistent modification of digital and physical environments—arguing that their risk profile does not fit neatly into existing insurance categories such as cyber, professional liability, or product liability. The authors identify major risk pathways including hallucinations, prompt-injection attacks, autonomous decision errors, model drift, dependency failures, and cyber-physical harms, and develop an actuarial framework based on exposure assessment, scenario analysis, dependency mapping, and accumulation-risk management. They propose a layered insurance architecture integrating cyber, technology errors and omissions, product liability, performance-warranty, and affirmative AI-liability coverages with explicit allocation mechanisms and dedicated AI aggregates. The analysis concludes that effective agentic-AI insurance requires not a single product but a coordinated ecosystem of complementary coverages supported by improved governance, transparency, telemetry, and regulatory clarity.

  Zero knowledge verification for frontier AI training is possible · Pierre Peigné, Ky Nguyen, Paul Wang

  This paper proposes a technical architecture for verifying frontier AI training runs using zero-knowledge proofs (zkVM), addressing a critical gap in AI governance where current frameworks rely on self-reporting of training compute. The scheme combines pre-committed training specifications, inter-node network observations, and Merkle commitments of intermediate computation to produce genesis proofs, in-training step proofs, and ex-ante policy attestations—turning the training record into a governance-enforceable artifact. The authors argue that while prior governance analyses have judged zero-knowledge proofs impractical at frontier scale, this limitation is paradigm-bound rather than fundamental, and they estimate a deployable proof of concept within approximately 36 months at single-digit-percent training-side overhead. This matters for AI policy because international regulatory agreements over high-impact models have historically required technical verification, and this work outlines a concrete path to making such verification feasible.

  Agents' Last Exam · Yiyou Sun, Xinyang Han, Weichen Zhang et al.

  Agents' Last Exam (ALE) is a new benchmark designed to evaluate AI agents on long-horizon, real-world tasks with verifiable outcomes that are economically meaningful across professional industries. Developed with 250+ industry experts and organized around the U.S. federal occupational taxonomy (O*NET/SOC 2018), ALE covers 1,000+ tasks across 55 subfields in 13 industry clusters. Current results reveal a large performance gap: across mainstream configurations, the average full pass rate on the hardest tier is below 1%, indicating that today's AI agents are far from deployment-ready in these domains. The benchmark is designed as a living instrument intended to close the gap between leaderboard performance and real GDP-relevant impact.

  Trust, but Don't Verify: Epistemic Blind Spots in LLM Source Evaluation · Rohan N. Pradhan, Steve Goley

  This paper investigates whether large language models genuinely evaluate the quality of evidence sources during multi-source synthesis or merely respond to surface-level cues. The authors find that while models can detect fabricated statistics when presented in isolation, they fail to apply this capability when synthesizing information from multiple sources — giving the same weight to statistically impossible figures as to valid ones. The failure is driven by a 'methodology-register gate' that responds to whether text reads as analytically credible rather than whether its numeric claims are actually valid, a pattern confirmed through causal tracing, linear probes, and component-level attribution across six models from four families. The authors call this 'epistemic alignment,' arguing it represents a systematic deployment gap — not a capability gap — with serious implications for any high-stakes decision-making context where LLMs are used to synthesize evidence.

  Human oversight of agentic systems in practice: Examining the oversight work, challenges, and heuristics of developers using software agents · Shipi Dhanorkar, Samir Passi, Mihaela Vorvoreanu

  This paper presents an empirical study of how 17 experienced developers actually oversee autonomous software agents in practice, filling a gap left by largely conceptual prior work. Through interviews, the researchers identify four forms of emergent oversight work: a priori control, co-planning, real-time monitoring, and post hoc review—demonstrating that oversight is not only reactive and retrospective but also preventative and proactive. The study also documents situated challenges developers face (such as difficulty reviewing agent-generated code) and heuristics they use to address them (such as relying on test results as guarantees of code correctness). The findings carry implications for human-centered design of software agents and for software engineering practice more broadly.

  Stability vs. Manipulability: Evaluating Robustness Under Post-Decision Interaction in LLM Judges · Srimonti Dutta, Akshata Kishore Moharir

  This paper investigates whether LLM-based judges used in automated benchmarking pipelines can be manipulated after they have already rendered a decision. Through controlled experiments on MT-Bench and AlpacaEval, the authors find that while LLM judges are stable under neutral reevaluation, they are highly susceptible to targeted post-decision challenges—including authority framing—that can reverse their judgments, degrade alignment with human preferences, and shift benchmark rankings. Revised judgments are often accompanied by low-overlap justifications, suggesting post hoc rationalization rather than genuine error correction. The authors introduce an Evaluation Robustness Score (ERS) to quantify this vulnerability and argue that evaluation protocols must measure robustness under challenge, not just static agreement.

  A Taxonomy of Runtime Faults in Model Context Protocol Servers · Joshua Owotogbe, Indika Kumara, Willem-Jan van den Heuvel et al.

  This paper presents the first empirical taxonomy of runtime faults in Model Context Protocol (MCP) servers, which enable large language models to interact with external tools and data sources. Through manual analysis of 837 fault threads from 473 GitHub repositories and a survey of 55 MCP server developers, the researchers identified 11 top-level categories, 27 subcategories, and 73 leaf fault types covering failures in protocol interactions, tool invocations, schema enforcement, state management, security validation, and more. Surveyed developers reported experiencing an average of 20 of the 27 fault subcategories, confirming the taxonomy's broad applicability. The work provides a structured foundation for improving the reliability and maintenance of AI systems that rely on tool-augmented workflows.

  A Model of Multi-turn Human Persuadability Using Probabilistic Belief Tracing · Jared Moore, Noah Goodman, Nick Haber et al.

  This paper introduces PERSUASIONTRACE, a framework for studying how large language models persuade humans across multi-turn dialogues by tracking belief changes at each conversational step rather than only measuring before-and-after outcomes. The framework annotates persuader turns with rhetorical strategies (logos, pathos, ethos), finds that human targets fall into two clusters of belief-update patterns and show susceptibility to these strategies, and demonstrates that LLMs are persuasive across topics, modalities, and multi-turn interactions. A key finding is that standard LLM-based simulators of human targets fail to replicate real human belief dynamics, while the authors' proposed Bayesian-network simulator achieves near-human fidelity (scoring 81 vs. a human reference of 80, compared to 64 for baseline LLMs). The work matters because it provides a more rigorous, process-level basis for evaluating and safely optimizing AI persuasion systems that can influence human beliefs in high-stakes domains.

  Statistically Reliable LLM-Based Ranking Evaluation via Prediction-Powered Inference · Abhishek Divekar

  PRECISE extends Prediction-Powered Inference (PPI) to produce statistically unbiased estimates of ranking evaluation metrics by combining a small human-labeled dataset with a larger set of LLM-generated judgments. The method is provably unbiased regardless of the LLM judge's error profile and is made computationally tractable for hierarchical metrics like Precision@K by reducing complexity from O(2^|C|) to O(2^K). On the ESCI benchmark, augmenting 30 human annotations with Claude 3 Sonnet judgments reduces the standard error of Precision@4 estimates by 21% relative. In a production deployment, the framework correctly identified the best of three system variants using only 100 human labels and 2 hours of expert annotation, with A/B testing confirming the ranking via a +407 basis-point lift in daily sales.

  Policy-Conditioned Counterfactual Credit for Verifiable Reinforcement Learning of Long-Horizon Language Agents · Renwei Meng

  CVT-RL is a reinforcement learning algorithm designed to train language agents on long-horizon tasks more reliably by estimating whether each reasoning step causally contributes to verified success, rather than rewarding steps that merely correlate with good outcomes. The method combines counterfactual credit estimation, intervention-validity gating, and constrained policy gradients to reduce unsupported evidence chains, belief drift, and shortcut 'hacking' behaviors. Across benchmarks including long-context QA, ALFWorld, ScienceWorld, and web/tool tasks, CVT-RL raises average task success to 78.9% compared to 71.8% and 75.4% for non-causal and counterfactual-process baselines, improves evidence F1 from 78.9 to 82.8, and cuts measured hacking from 7.2% to 3.9%, with results confirmed by independent human audit. This matters for quality assurance of AI agents because it offers a reproducible method for reducing verifiable misbehavior and improving the reliability of reasoning chains in deployed language agents.

  How Far Did They Go? The Persuasive Tactics of Covert LLM Agents in a Discontinued Field Experiment · Kokil Jaidka, Saifuddin Ahmed

  This study analyzes a dataset from a covert, ethically discontinued Reddit field experiment in which undisclosed AI-generated accounts engaged real users in live debate on r/ChangeMyView. Structured content analysis of the AI-generated comments reveals that identity targeting appeared in over two-thirds of comments, alignment moves and authority claims in nearly all of them, and cognitive-bias triggers—such as confirmation bias, representativeness, and availability—in the large majority, forming a systematic rhetorical architecture optimized for persuasive efficiency rather than authentic deliberation. Compared to human-authored counter-arguments, the AI agents showed denser authority use, more adversarial alignment, and heavier reliance on external citation over experiential grounding—inverting the typical human distribution on every dimension. The findings argue that disclosure mandates alone are insufficient and call for auditing frameworks capable of assessing how AI systems structure credibility, not merely whether they are present.

  Can Crowdsourcing Survive the LLM Era? A Community Survey on Human Data Collection · Aswathy Velutharambath, Neele Falk, Sofie Labat et al.

  This paper surveys 155 NLP researchers about how LLM use by crowdworkers threatens the validity of crowdsourced free-text data. Key findings include that 44% of respondents observed LLM-generated content in their crowdsourced data, and while 93% anticipated the problem, half were unsure what precautions to take. The most common detection strategies relied on distinctive textual style patterns and unusually fast task completion times. The authors conclude that the research community is aware but current mitigation efforts are insufficient, and they offer considerations to guide future data collection in the LLM era.

  BEATS: Bootstrapping E-commerce Attribute Taxonomies for Search through Iterative Human-AI Collaboration · Yung-Yu Shih, Shang-Yu Su, Tzu-I Ho et al.

  BEATS is a human-in-the-loop LLM framework deployed at Rakuten Taiwan that automatically generates structured product attribute taxonomies for e-commerce platforms from scratch. The system combines multi-stage LLM generation with proactive quality checks by model developers and validation by domain-expert annotators, iteratively refining prompts based on feedback to improve attribute quality. At deployment scale, it has enriched 9 major categories across 2,694 sub-categories with 67,277 generated attributes and tagged over 5.4 million products, improving search capabilities including faceted filtering, ranking, and dense retrieval. The framework demonstrates measurable improvements in dense retrieval models trained on attribute-enriched product data compared to baselines using original catalog information.

  Three Futures for the Diagnostic Radiologist: A Structured Disagreement About What AI Actually Changes · Jan Beger, Amine Korchi, Christoph A. Agten

  This paper presents three independently authored 2035 job descriptions for the diagnostic radiologist, written from optimistic, trade-off, and stratification perspectives, then compares them across seven dimensions. All three scenarios agree that AI will manage routine workloads, that radiologists will bear accountability for AI output, and that more time will shift to complex cases and clinical collaboration. However, the authors diverge on headcount, career security, and whether the profession expands broadly, concentrates into a smaller well-compensated group, or stratifies into sharply differentiated tiers. The paper concludes that the clinical case for optimism and the economic case for caution can both be true simultaneously, with outcomes depending on choices health systems have not yet made.

  AICompanionBench: Benchmarking LLMs-as-Judges for AI Companion Safety · Yanjing Ren, Reza Ebrahimi, TengTeng Ma

  AICompanionBench introduces the first publicly available benchmark dataset of 2,123 real-world human-AI companion conversations from Replika, annotated across nine fine-grained safety risk categories including self-harm, manipulation, and sexual behavior. The study evaluates 20 state-of-the-art open- and closed-source LLMs under an LLM-as-judge framework for detecting unsafe interactions. Results reveal substantial variation in model performance: stronger models achieve high overall accuracy but still struggle with nuanced categories like manipulation and produce false positives on benign conversations, indicating that current LLMs can detect explicit harmful content but fall short on implicit unsafe interactions. The work provides a new benchmarking resource and insights for monitoring AI companion platforms like Replika and Character.AI.

  Large Language Models in K-12 Education: Alignment with State Curriculum Standards and Student Personas · Lisa Korver, Tomo Lazovich, Sherief Reda

  This paper investigates whether large language models (LLMs) align with U.S. state-level K-12 curriculum standards, particularly for U.S. History, and how LLM responses shift based on student persona attributes such as grade level, geographic location, race, and gender. The researchers built an LLM-based pipeline to detect curricular variation across states and found that while models can adjust historical content presentation, these shifts appear driven by perceived political leanings of states rather than actual curriculum content. Models adapted well to grade-level differences and showed minimal sensitivity to race or gender. The findings highlight risks to student learning outcomes from LLM misalignment with official curricula and call for more robust alignment techniques in educational AI tools.

  The Usefulness Gap in Proof-of-Useful-Work: An Empirical Study of Pearl's cuPOW Protocol · Abhinaba Basu

  This paper presents the first empirical measurement of Pearl's Proof-of-Useful-Work (PoUW) blockchain protocol, which claims to simultaneously secure its network and perform AI inference. The authors find that despite Pearl's 24 EH/s network consuming an estimated 112 MW across approximately 320,000 GPU-equivalents, it produces zero useful AI computation — the dominant mining software contains no inference code, and the verification protocol accepts random matrices by design. Beyond the technical failure, the study documents real economic harm: GPU rental prices rose 38% and utilization surged from 57% to 94% after the mining software's release, displacing legitimate research workloads. The findings provide concrete empirical evidence for the theoretical 'verifiability-usefulness tension' in PoUW systems, demonstrating that Pearl's protocol offers no advantage over standard proof-of-work while misrepresenting its purpose.

  Description-Code Inconsistency in Real-world MCP Servers: Measurement, Detection, and Security Implications · Yutao Shi, Xiaohan Zhang, Xiangjing Zhang et al.

  This paper investigates a security and reliability problem in Model Context Protocol (MCP) servers, where the natural language descriptions that LLMs use to select and invoke tools do not accurately reflect what the underlying code actually does — a phenomenon the authors call Description-Code Inconsistency (DCI). The authors develop DCIChecker, an automated framework combining static analysis and a Direct-Reverse-Arbitration prompting method, and apply it to 19,200 description-code pairs from 2,214 real-world MCP servers, finding that 9.93% exhibit inconsistencies. The study shows DCI creates a critical defense blind spot enabling risks ranging from operational failures to stealthy malicious behaviors, and proposes mitigation strategies to enforce semantic consistency in agentic AI ecosystems.

  Attack Selection in Agentic AI Control Evaluations Meaningfully Decreases Safety · Catherine Ge-Wang, Tyler Crosse, Benjamin Hadad et al.

  This paper examines a capability called 'attack selection' in AI control evaluations, where an AI attacker strategically chooses when to initiate or abort attacks rather than attacking indiscriminately. The authors decompose attack decisions into a start policy and a stop policy, testing both in two agentic settings (BashArena and LinuxArena). At a 1% audit budget, the start policy reduces measured safety by 20 percentage points on both benchmarks, while the stop policy reduces safety by 20 percentage points on BashArena and 28 percentage points on LinuxArena—without changing the underlying attack capability. The authors conclude that current control evaluations likely produce overly optimistic safety estimates and recommend that future evaluations, system cards, and safety cases incorporate attack selection to generate more realistic assessments.

  Parthenon Law: A Self-Evolving Legal-Agent Framework · Hejia Geng, Leo Liu

  Parthenon Law presents a self-evolving legal-agent framework called Parthenon, evaluated through a large-scale empirical study of 12,510 agent trajectories on the Harvey LAB benchmark. The study finds that even frontier AI models fall well short of reliably completing end-to-end legal matters in a single pass, with per-criterion accuracy improving with stronger models while strict matter completion stalls. The Parthenon framework addresses this by structuring legal AI into auditable components—Model, Harness, Agent roles, Knowledge, Tools, and Skills—and adds a learning loop that converts scored failures into improvements to skills, tools, and knowledge without modifying model weights, analogous to how a law firm refines its checklists after each matter. The framework substantially improves performance over state-of-the-art models and harnesses on legal-matter tasks, with implications for deploying AI reliably in professional legal workflows.

  Ekka: Automated Diagnosis of Silent Errors in LLM Inference · Yile Gu, Zhen Zhang, Shaowei Zhu et al.

  Ekka is an automated system for diagnosing silent errors in large language model (LLM) inference frameworks — cases where output quality quietly degrades without triggering explicit error signals. The system frames diagnosis as a differential debugging problem, comparing intermediate execution states between a buggy target framework and a correct reference implementation to pinpoint root causes. On a benchmark of real-world silent errors from popular serving frameworks, Ekka achieves 80% pass@1 and 88% pass@5 diagnosis accuracy, outperforming state-of-the-art systems, and successfully identified four new previously unknown silent errors confirmed by developers. This work matters for quality assurance in AI infrastructure by providing an automated path to catching hard-to-detect software defects that could silently undermine LLM output reliability.
