The authors call this pre-commit noninterference (PNI), measure its violation by the total-variation distance D_A between the agent's views under the two coin values, and show the worst-case bias is (1-ε)D_A. In experiments, a visible audit notice let a real LLM agent detect audits and follow an injection that named it, so the plain certificate failed, while a silent audit restored validity.","solution":"A fresh coin per audited call closes the timing channel; padding only narrows it.","labels":["research","security"],"sourceUrl":"https://arxiv.org/abs/2610.37055v1","publishedAt":"2026-10-27T11:24:12.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["model_evasion"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":[],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2026-10-27T11:24:12.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity"],"aiComponentTargeted":"agent","llmSpecific":true,"classifierConfidence":0.9,"researchCategory":"preprint","atlasIds":null}}
