LeaseGuard: Incumbent-Preserving Admission Control for Privileged LLM Agents
LeaseGuard is a deterministic admission control layer that prevents privileged LLM agents from displacing healthy incumbent processes.
Researchers present LeaseGuard, a deterministic admission control layer designed to prevent privileged LLM agents from displacing healthy incumbent processes. The system uses resource leases, health checks, and effect-aware admission to ensure incumbent preservation. Evaluation on 60 conflict scenarios shows it eliminates unauthorized preemption and increases safe completion rates.
- LeaseGuard is an admission control layer for privileged LLM agents to prevent unauthorized resource preemption.
- It reduces unauthorized preemption from 73.3% to 0.0% in evaluated conflict scenarios.
- The system uses canonical resource leases and incumbent-health checks for deterministic admission.
From the original article
1 min read at arxiv.orgPrivileged language-model agents can satisfy a new system task by displacing a healthy incumbent that depends on the same file, process, socket, lock, or capacity allocation. This failure arises because execution privilege determines whether an operation can run, not whether the requester may preempt the current resource owner.
