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 JavaScript excerpt only defines path filters. The native executable analysis shows credential-discovery candidates but cannot establish their reachability or behavior, leaving a material gap that requires manual review. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-19T00:16:44.165Z - **Finished:** 2026-10-19T00:18:02.049Z - **Download time:** 39919 ms - **Static scan time:** 595 ms - **AI review time:** 37369 ms - **Total time:** 77884 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 confirmed. The packaged native executable contains bounded embedded source candidates that include credential discovery, but their reachability and resulting data flow are unresolved. - **Trigger:** Unknown; the inspected evidence does not establish when the embedded code runs. - **Impact:** Potential exposure of local credentials remains unresolved; no recipient or completed transfer was verified. - **Evidence paths:** bin/reason.exe, .lpm-inspection-Xq8VZI/0-408d8e2ba1bd.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-19T00:18:02.049Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The offline report exposes candidate source that reads local agent credentials, but does not establish whether it is reachable or where any collected values go. - **Rationale:** The manifest has no install lifecycle hook, and the flagged JavaScript excerpt only defines path filters. The native executable analysis shows credential-discovery candidates but cannot establish their reachability or behavior, leaving a material gap that requires manual review. - **Files touched:** bin/reason.exe ### Review decision - **Verdict:** Manual Review - **Confidence:** 88.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json identifies a Windows ARM64 CLI package and contains no lifecycle scripts., The flagged runtime defines filters for project paths such as agent command and agent directories; this excerpt does not show a configuration write., The executable analysis reports credential discovery in embedded source, but only as bounded source candidates., The analysis says embedded source reachability and other native behavior remain unresolved. - **Evidence against:** The manifest has no preinstall, install, or postinstall hook., The inspected runtime excerpt defines path filters but does not establish an agent configuration mutation. ## Affected versions and remediation This report applies to @reason-machines/cli-win32-arm64@0.2.411. - Review the evidence and your use of @reason-machines/cli-win32-arm64@0.2.411 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.
