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 and flagged sandbox source do not establish malicious behavior, but offline analysis leaves significant native executable behavior unresolved. Manual review is warranted; the available evidence does not support a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-18T23:09:17.221Z - **Finished:** 2026-10-18T23:10:29.325Z - **Download time:** 27120 ms - **Static scan time:** 610 ms - **AI review time:** 44373 ms - **Total time:** 72104 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 established from the inspected source. Material behavior in the bundled Windows executables remains unresolved. - **Trigger:** Running the Windows CLI or its native components would activate the unresolved behavior. - **Impact:** The effect of the unresolved native behavior cannot be determined from the inspected evidence. - **Evidence paths:** .lpm-inspection-ZKrI1r/0-a4b44a0dd160.txt, .lpm-inspection-ZKrI1r/1-51bee02bcb73.txt, .lpm-inspection-ZKrI1r/2-a76abd7182ee.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T23:10:29.325Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The available offline analyses show bounded embedded source and native call information, but do not resolve all executable behavior or clipboard data flow. - **Rationale:** The manifest and flagged sandbox source do not establish malicious behavior, but offline analysis leaves significant native executable behavior unresolved. Manual review is warranted; the available evidence does not support a block. - **Files touched:** bin/reason.exe, bin/native/win32/prebuilds/win32-x64/win32-platform.node, bin/runtime/srt/vendor/srt-win/x64/srt-win.exe ### Review decision - **Verdict:** Manual Review - **Confidence:** 91.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies a Windows x64 CLI package and contains no lifecycle scripts or JavaScript entry point., The bundled sandbox runtime lists project and agent configuration paths among paths it protects from writes., The trusted offline analysis of the main executable contains only bounded embedded-source windows, which do not establish the executable’s full behavior., The native Windows module imports clipboard APIs, but the available analysis does not resolve their purpose or data flow., The bundled Windows sandbox executable has uninspected native call targets, so its full behavior is not established. - **Evidence against:** The inspected manifest contains no install lifecycle hook, and the flagged sandbox source excerpt describes protected paths rather than configuration changes. ## Affected versions and remediation This report applies to @reason-machines/cli-win32-x64@0.2.407. - Review the evidence and your use of @reason-machines/cli-win32-x64@0.2.407 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.
