Governed Deduction: Policy-Grounded Premise Authorization Beyond Relevance

The paper introduces Governed Deduction (GD), a framework that distinguishes between premise relevance and premise authorization in reasoning systems. Using an RBAC-augmented Spider benchmark, the authors create 4,461 authorization pairs where the same premise is either allowed or denied for a transition, revealing that simple linear models fail to capture policy constraints. The study demonstrates that matched controls and leakage audits are essential for evaluating policy-sensitive reasoning.

From Events to Reasoning: Hierarchical Rule Composition over Explicit States

The paper introduces the Event Reasoning System (ERS), a framework that represents reasoning as an explicit event graph and uses hierarchical rule composition to manage dependencies and revisions. ERS employs semantic features to nominate candidate objects and rule bindings, while low‑level rules provide reusable transformations and high‑level control rules organize subgoals, ensuring that only admissible operations enter accepted reasoning paths. Empirical results on structured‑event graphs show ERS can build long dependency chains, eliminate irrelevant operations, and maintain correctness across numerous test cases, while reducing inference time by over 50% compared to single‑level control.

Approval Laundering: Systematizing Approval--Execution Binding Failures in AI Coding-Agent Harnesses

The paper investigates a critical flaw in AI coding-agent systems such as Claude Code, Codex CLI, and Cursor, where the action approved by a human is not the same as the action executed by the harness. It introduces the concept of Approval Laundering, categorizing six systematic failure modes—Scope, Argument, Temporal, Tool, Delegation, and Semantic laundering—and demonstrates these failures through controlled experiments. The authors propose an Approval Token mechanism that mitigates some laundering types but leaves others unaffected, highlighting the limitations of current enforcement strategies.

Cross-Interface Authorization for AI Computer-Use Agents

The paper introduces a protocol for cross‑interface authorization of AI computer‑use agents, ensuring that policy decisions remain consistent across graphical interfaces, command lines, APIs, scripts, and Model Context Protocol servers. It defines a profile‑bounded system that enumerates all effect‑bearing routes, normalizes requests to canonical effects, issues prepare tickets, and re‑verifies all relevant state at commit time, requiring a sink receipt for a committed result. Extensive testing across two runtime mappings produced thousands of traces, with rigorous checks confirming no semantic regressions, mutant rejections, and correct outcome matching.

SecureGARD: Dynamic Ontology-Guided Governance for Secure Tool-Using LLM Agents

SecureGARD is a dynamic ontology‑guided governance framework designed to secure tool‑using large language model agents. It grounds heterogeneous tool calls in a shared semantic representation, using an executable ontology combined with episode‑level task state to make deterministic ready, waiting, and forbidden decisions. The system evolves its ontology offline from verified training executions, ensuring logical consistency and protecting entailments, and achieves a 0% attack success rate across multiple benchmarks while improving task utility under attack.
