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:** 0.2.421 - **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 manifest has no lifecycle hooks, and the inspected runtime location only lists protected configuration paths. The native executable's limited analysis leaves material behavior unresolved, so a malicious verdict is not supported and manual review is appropriate. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-19T04:41:39.232Z - **Finished:** 2026-10-19T04:42:31.078Z - **Download time:** 9888 ms - **Static scan time:** 597 ms - **AI review time:** 41360 ms - **Total time:** 51846 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 established from the inspected source. The packaged native executable remains unresolved because its offline analysis covers only bounded embedded source candidates. - **Trigger:** Unknown; native executable behavior could not be fully resolved by static analysis. - **Impact:** Unknown; the available evidence is insufficient to determine the executable's full effects. - **Evidence paths:** bin/reason, .lpm-inspection-6jhVy9/0-d891d4a23f83.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-19T04:42:31.078Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The available analysis does not establish which embedded code is reachable or whether other native behavior exists. - **Rationale:** The manifest has no lifecycle hooks, and the inspected runtime location only lists protected configuration paths. The native executable's limited analysis leaves material behavior unresolved, so a malicious verdict is not supported and manual review is appropriate. ### Review decision - **Verdict:** Manual Review - **Confidence:** 78.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json identifies this as a Darwin ARM64 native binary package and contains no lifecycle scripts., The runtime excerpt lists .mcp.json and related configuration paths as sandbox protections; it does not establish a configuration write., Offline analysis of bin/reason is limited to embedded source candidates and cannot establish native loader reachability or rule out other behavior. - **Evidence against:** The inspected package manifest does not define install-time hooks., The inspected runtime location does not show an agent configuration mutation. ## Affected versions and remediation This report applies to @reason-machines/cli-darwin-arm64@0.2.421. - Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.421 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.
