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 sandbox runtime excerpts do not establish malicious behavior. The primary Mach-O executable has only bounded embedded-source analysis that cannot rule out material behavior, so manual review is warranted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-22T00:59:37.150Z - **Finished:** 2026-10-22T01:00:07.649Z - **Download time:** 2797 ms - **Static scan time:** 613 ms - **AI review time:** 27088 ms - **Total time:** 30499 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 JavaScript. The primary native executable remains unresolved because its analysis does not establish reachability or rule out other behavior. - **Trigger:** Unknown; activation and callers for the native executable were not resolved by the available analysis. - **Impact:** Potential native behavior cannot be assessed from the available evidence. - **Evidence paths:** .lpm-inspection-tsjjqH/0-921b773e7cbd.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-22T01:00:07.649Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The offline analysis provides bounded embedded-source candidates, not a complete behavioral account of the executable. - **Rationale:** The manifest has no install lifecycle hook, and the inspected sandbox runtime excerpts do not establish malicious behavior. The primary Mach-O executable has only bounded embedded-source analysis that cannot rule out material behavior, so manual review is warranted. - **Files touched:** bin/reason, bin/runtime/srt/sandbox-runtime.mjs ### Review decision - **Verdict:** Manual Review - **Confidence:** 90.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json identifies this as a macOS ARM64 CLI package and defines no lifecycle scripts., The native analysis covers bounded embedded-source windows only and states that it cannot establish whether they are reachable or rule out other native behavior., The flagged JavaScript includes child-process support and loopback proxy code; these excerpts do not establish an attack. - **Evidence against:** No package lifecycle hook is defined in package.json., The inspected JavaScript uses loopback addresses for local proxy behavior; no external endpoint or credential transfer was established in the inspected excerpts. ## Affected versions and remediation This report applies to @reason-machines/cli-darwin-arm64@0.2.512. - Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.512 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.
