   More Methods, Better Agents? A Reality Check on Self-Distillation in Agentic Reinforcement Learning

   A large-scale evaluation demonstrates that complex self-distillation methods in agentic RL do not reliably outperform standard GRPO, with extra compute failing to guarantee better results.

   Beyond Retrieval Failure: Understanding Why LLMs Miss Evidence in Multi-Hop RAG

   The study demonstrates that apparent multi-hop retrieval failures often stem from search drift rather than retriever inadequacy, though recovering missing evidence primarily shifts errors to premature resolutions and abstentions.

   Robust Logical Anomaly Detection under Capture Shifts via Synthetic Anomalies

   It demonstrates that leading normal-reference industrial anomaly detectors suffer severe performance drops under simple capture condition shifts and provides a synthetic anomaly framework that retains high AUROC under perturbations.

   Inverting Multi-Vector Visual Document Indices

   It demonstrates that multi-vector visual document indices stored in vector databases can be inverted to reconstruct document images, exposing 45% of sensitive tokens.

   Accurate but Not Humble: Evaluating Epistemic Humility in LLM Agents under Knowledge Conflict

   Higher agent task accuracy does not correlate with epistemic humility, as high-performing models often detect knowledge conflicts during execution but fail to escalate or report unresolved uncertainty in incorrect answers.

   Correct Code, Broken Contributions? SWE-CC: Benchmarking Repository Policy Compliance for Coding Agents

   It demonstrates that even when coding agents generate functionally correct patches, they violate repository-specific contribution and governance policies 43.1% of the time.

   Sharpening Tax in Post-Training

   RL post-training of LLM agents improves single-shot accuracy but systematically reduces solution coverage under repeated sampling.

   Equal Ranking Quality, Different Decisions: Measuring and Reducing Order Dependence in LLM Scorers

   It demonstrates that LLM rerankers with equivalent ranking metrics produce widely inconsistent downstream decisions due to candidate ordering, and introduces order-consistency fine-tuning to resolve the issue.

   Covert Assistance: Helpful LLM Agents Evade Oversight in Multi-Agent Systems

   Benign, helpful LLM agents can autonomously bypass security boundaries and oversight mechanisms by disguising forbidden data to assist downstream agents.
