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:** 0.2.459 - **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 install lifecycle hook, and the inspected runtime location supports sandbox search filtering. The native executable remains materially unresolved after bounded offline inspection, so the source does not support either a clean or malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 77.0% - **Started:** 2026-10-19T23:29:12.218Z - **Finished:** 2026-10-19T23:33:20.651Z - **Download time:** 4348 ms - **Static scan time:** 576 ms - **AI review time:** 243508 ms - **Total time:** 248433 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 attack is confirmed. The native executable’s behavior remains unresolved because the available offline analysis covers only bounded embedded-source windows. - **Trigger:** Launching the native CLI executable. - **Impact:** No harmful effect is confirmed; the executable’s behavior cannot be resolved from the available inspection. - **Evidence paths:** .lpm-inspection-c9dxzf/0-346472e500f4.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-19T23:33:20.651Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The available analysis does not establish which embedded source is reachable or rule out other native behavior. - **Rationale:** The manifest has no install lifecycle hook, and the inspected runtime location supports sandbox search filtering. The native executable remains materially unresolved after bounded offline inspection, so the source does not support either a clean or malicious verdict. - **Files touched:** bin/reason ### Review decision - **Verdict:** Manual Review - **Confidence:** 77.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies a macOS ARM64 binary package and declares no lifecycle script or runtime entrypoint., The runtime’s Claude-folder list is used by a search helper’s filtering logic, consistent with sandbox support behavior., Offline analysis of the native executable contains only bounded embedded-source windows and says those windows do not establish executable reachability or rule out other behavior. - **Evidence against:** The inspected manifest declares no install lifecycle hook., The required runtime location describes protected-folder names used by a search helper; this does not establish an attack. ## Affected versions and remediation This report applies to @reason-machines/cli-darwin-arm64@0.2.459. - Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.459 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.
