Privacy Policy Enforcement Guardrails for Data-Sensitive Retrieval-Augmented Generation
arXiv:2605.17034v2 Announce Type: replace Abstract: Standard PII filters often miss contextual data leakage in RAG systems, such as non-regulated attribute clusters that collectively identify individuals. We introduce a Privacy Policy Enforcement (PPE) framework using dual one-class density estimators with fused text embeddings and a calibrated abstain region for out-of-distribution inputs. Using an axis-stratified, multi-LLM synthetic data pipeline across medicine, finance, and law, we...
Ethical Hyper-Velocity (EHV): A Hardware-Rooted Zero-Trust Runtime Enforcement Architecture for Agentic AI Systems
arXiv:2605.17909v2 Announce Type: replace Abstract: As autonomous agentic systems scale across regulated critical infrastructures, the lack of mechanistic, hardware-rooted enforcement for high-frequency policy updates presents a fundamental safety gap. We present Ethical Hyper-Velocity (EHV), a governance-aware runtime enforcement architecture for agentic systems that combines Grammar-Constrained Decoding (GCD) for inline policy-constrained token generation, Causal Graph CRDT-based policy...
Snowflake buys Natoma to help freeze out rogue agents
Snowflake is acquiring Natoma, a startup that provides a gateway for managing AI agent permissions across enterprise applications. This acquisition is part of Snowflake's strategy to establish an "agentic control plane," ensuring that AI agents can interact with business systems while adhering to strict security and governance policies. Natoma's technology enforces identity verification and access controls at the level of individual tool calls, allowing for secure and controlled AI actions.
UK-France 'One-In, One-Out' migrant deal extended until October, minister says
The policy, which has been enforced since September 2025, has seen fewer than 4% of illegal migrants returned to France. France and the UK have agreed to extend their "one-in, one-out" migrant returns agreement until 1 October, a French minister said on Wednesday. The scheme, known as Operation Hillmore, came into force in September last year as part of efforts by London and Paris to tackle illegal migration across the English Channel.
ScenePilot: Controllable Boundary-Driven Critical Scenario Generation for Autonomous Driving
Announce Type: replace Abstract: Safety-critical scenarios are central to evaluating autonomous driving systems, yet their rarity in naturalistic logs makes simulation-based stress testing indispensable. Most scenario generation methods treat surrounding agents as adversaries, but they either (i) induce failures without explicitly modeling vehicle-road physical limits, yielding visually extreme yet physically unsolvable crashes, or (ii) enforce physical feasibility or policy feasibility in...
Interaction-Limited Safe Continuous-Time RL for Dynamical Medical Treatment
arXiv:2606.01051v1 Announce Type: new Abstract: Dynamic medical treatment requires deciding treatment intensity and intervention timing, while patient states evolve continuously and adverse events may occur between clinical interactions. Most existing treatment learning methods assume fixed schedules or enforce safety only at discrete decision points. We propose Interaction-Limited Safe Continuous-Time Reinforcement Learning, a framework that jointly optimizes treatment administration and...
WATCH: Police absent from Delaney Hall chaos as agitators block ICE vehicles and agents use pepper spray
Mayor Ras Baraka’s police department was nowhere to be found as tensions rose late Wednesday outside the Delaney Hall illegal immigrant detention center. Protesters took over roles typically reserved for police, while ICE agents deployed pepper spray after a federal vehicle entered the premises and sparked chaos among the crowd.Baraka, who lost the 2025 Democratic gubernatorial primary to Gov. Mikie Sherrill, had previously been arrested outside Delaney Hall during similar mayhem last year...
Show HN: Nucleus – A security-hardened, Nix-native container runtime
Extremely lightweight, security-hardened, declarative container runtime for agents and production services Nucleus is a minimalist container runtime for Linux. It provides isolated execution environments using Linux kernel primitives without the overhead of traditional container runtimes. For production services, it is designed around a fully declarative model: Nix builds the root filesystem, the NixOS module declares the service, and Nucleus mounts a pinned, reproducible closure at runtime.
An Organization-Scoped LLM Agent Runtime Architecture for Regulated Cybersecurity Operations
Announce Type: new Abstract: Regulated cybersecurity workflows lack a runtime substrate that enforces organization-level scope across retrieval, tool calls, memory, findings, reports, and audit while remaining model-agnostic and locally deployable. Recent large language model (LLM) agent systems report strong results on isolated cybersecurity tasks, yet they do not by themselves define an auditable platform architecture for regulated security operations centre (SOC) and compliance workflows,...
Zero knowledge verification for frontier AI training is possible
arXiv:2606.05433v1 Announce Type: new Abstract: Frontier AI governance frameworks increasingly use cumulative training compute as the primary criterion for designating high-impact models, but enforcement rests on self-reporting because no technical verification primitive for training exists. Any future international agreement on frontier AI faces the same problem at higher stakes: coordinated regulation of technologies with significant externalities has historically rested on technical...
