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 flagged agent-path match is part of a protected-path list. The native CLI's behavior remains unresolved after bounded offline inspection, so a clean verdict is not supported. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-19T20:05:43.350Z - **Finished:** 2026-10-19T20:06:27.153Z - **Download time:** 5677 ms - **Static scan time:** 590 ms - **AI review time:** 37536 ms - **Total time:** 43803 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 was identified in the inspected JavaScript source. The native CLI executable remains materially unresolved because its limited embedded source analysis cannot establish which code runs. - **Trigger:** Invoking the packaged native CLI executable. - **Impact:** The executable's effects cannot be determined from the inspected evidence. - **Evidence paths:** .lpm-inspection-XHTclG/0-4891dfccc558.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-19T20:06:27.153Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The available analysis shows bounded embedded source candidates but does not resolve their reachability or other executable behavior. - **Rationale:** The manifest has no install lifecycle hook, and the flagged agent-path match is part of a protected-path list. The native CLI's behavior remains unresolved after bounded offline inspection, so a clean verdict is not supported. - **Files touched:** bin/reason ### Review decision - **Verdict:** Manual Review - **Confidence:** 78.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies a macOS ARM64 native CLI package and contains no lifecycle hooks., The flagged runtime match lists agent configuration paths among protected paths; it does not show agent configuration mutation., The native executable analysis contains only bounded embedded source windows and says they do not resolve loader reachability or other native behavior., One embedded source candidate describes a Reason headless worker with sandboxed execution as its default. - **Evidence against:** No concrete attack behavior was established in the inspected JavaScript source., The native CLI executable is 71 MB, and its behavior is not resolved by the available bounded analysis. ## Affected versions and remediation This report applies to @reason-machines/cli-darwin-arm64@0.2.449. - Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.449 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.
