Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Manual Review - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Under Review - **Threat category:** Unknown - **Selected version:** 0.2.401 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected manifest and runtime excerpt establish no concrete attack, but the native CLI’s behavior remains materially unresolved by bounded analysis. Manual review is appropriate rather than inferring maliciousness from the binary alone. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-18T17:11:19.188Z - **Finished:** 2026-10-18T17:16:42.100Z - **Download time:** 10260 ms - **Static scan time:** 582 ms - **AI review time:** 312070 ms - **Total time:** 322912 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No concrete attack was identified in the inspected source. The shipped native CLI remains unresolved because the available analysis covers only bounded embedded-source windows. - **Trigger:** Execution of the shipped native CLI. - **Impact:** No specific harmful effect is established; native behavior remains undetermined. - **Evidence paths:** .lpm-inspection-qSWJ7t/0-8314bea4cc30.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T17:16:42.100Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The analysis does not establish which embedded code is reachable or rule out other native behavior. - **Rationale:** The inspected manifest and runtime excerpt establish no concrete attack, but the native CLI’s behavior remains materially unresolved by bounded analysis. Manual review is appropriate rather than inferring maliciousness from the binary alone. - **Files touched:** bin/reason ### Review decision - **Verdict:** Manual Review - **Confidence:** 83.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies this as the Darwin ARM64 CLI and contains no lifecycle scripts., The runtime bundle lists .mcp.json and Claude command and agent directories among sandbox protection paths; this excerpt does not establish an agent configuration mutation., The shipped native CLI is 72,877,152 bytes; its bounded embedded-source analysis says it cannot establish reachability or rule out other native behavior. - **Evidence against:** No install-time lifecycle trigger or concrete attack behavior was identified in the inspected source. ## Affected versions and remediation This report applies to @reason-machines/cli-darwin-arm64@0.2.401. - Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.401 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
