Foundations of a Time-Consistent Counterfactual Actuarial Runtime for Autonomous AI Agents

Hao-Hsuan Chen

We propose a foundational runtime actuarial layer for autonomous AI agents in which every side-effect-bearing action carries a time-consistent, counterfactual risk toll computed ag…

Insuring Every Action: An Authority Frontier Framework for Runtime Actuarial Control of Autonomous AI Agents

Hao-Hsuan Chen

Autonomous AI agents increasingly issue side-effect-bearing actions: database mutations, refunds, payments, external commitments. We propose the Actuarial Action Interface (AAI), a…

Code Generation by Differential Test Time Scaling

Yifeng He, Ethan Wang, Jicheng Wang +2

Test-time scaling has emerged as a promising approach for improving code generation by exploring large solution spaces at inference time. However, existing methods often rely on pu…

Hunting Vulnerability Variants in AI Infra: Measurement and Reference-Driven Detection

Tian Dong, Yanjun Chen, Shoufeng Zhang +6

AI infra has become a shared execution layer for model training, deployment, and agent orchestration. Because many projects reimplement similar model-centric workflows, a vulnerabi…

CHI-Bench: Can AI Agents Automate End-to-End, Long-Horizon, Policy-Rich Healthcare Workflows?

Haolin Chen, Deon Metelski, Leon Qi +30

End-to-end automation of realistic healthcare operations stresses three capabilities underrepresented in current benchmarks: policy density, decisions must be grounded in a large l…

ContractBench: Can LLM Agents Preserve Observation Contracts?

Jicheng Wang, Yifeng He, Zili Wang +3

Tool-augmented LLM agents call APIs whose intermediate outputs, such as presigned URLs, session tokens, and OAuth state parameters, are observation contracts: artifacts whose later…
