ProbeGuard: Proactive Pre-Execution Threat Detection for Smart Contracts via Active State Probing

Smart-contract security / pre-execution defense

Local-fork active probing
Rust/revm sandbox
L1/L2 cascaded screening

Studies pre-signature smart-contract risk detection through local-fork active probing, a long-lived Rust/revm execution service, and layered L1/L2 screening. The current artifact reproduction target reports 9.74% FPR and 81.82% recall.

Detecting Stealth Sycophancy in Mental-Health Dialogue with Dynamic Emotional Signature Graphs

arXiv:2605.03472 [cs.CL, cs.AI]

Authors: Tianze Han, Beining Xu, Hanbo Zhang, Yongming Lu
DESG-Ensemble held-out aggregate macro-F1: 0.9353

Introduces Dynamic Emotional Signature Graphs (DESG) for offline mental-health dialogue evaluation, representing dialogue windows as decoupled clinical states and using asymmetric clinical geometry to detect stealth sycophancy risk. This is not a clinical diagnosis or treatment system.

CF-Ask: Counterfactual Questioning for Safe Cognitive Reframing in Emotional Support Dialogue

Emotional-support dialogue / safe cognitive reframing

CF-AskBench scaffold
150-context three-rater pilot
4,500 human labels

Studies counterfactual question selection for emotional-support dialogue: generating candidate questions, simulating short-term user trajectories, and applying safety gates before selecting a question for cognitive reframing. The current pilot diagnoses selector calibration and safety-routing signals without claiming superiority over strong baselines.
