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 runtime excerpt do not establish malicious behavior, but the package's primary native executable has only bounded embedded-source analysis, including authentication-store reads without resolved callers or sinks. This material gap prevents a source-grounded clean verdict; no concrete attack was verified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-19T20:04:09.739Z - **Finished:** 2026-10-19T20:05:07.798Z - **Download time:** 22733 ms - **Static scan time:** 595 ms - **AI review time:** 34730 ms - **Total time:** 58059 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. The package's native CLI remains materially unresolved because the available embedded-source analysis is bounded. - **Trigger:** Running the packaged CLI would activate the native executable; its relevant code paths could not be established from the available analysis. - **Impact:** Unknown; the inspected evidence does not confirm credential transfer or another attack effect. - **Evidence paths:** bin/reason, .lpm-inspection-CphFJF/0-3b2881dea1ef.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-19T20:05:07.798Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The analysis exposes some embedded CLI source, including authentication-store reads, but does not establish reachability, data flow, or any recipient. - **Rationale:** The manifest and flagged runtime excerpt do not establish malicious behavior, but the package's primary native executable has only bounded embedded-source analysis, including authentication-store reads without resolved callers or sinks. This material gap prevents a source-grounded clean verdict; no concrete attack was verified. ### Review decision - **Verdict:** Manual Review - **Confidence:** 86.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies this as the Darwin x64 Reason CLI and declares no lifecycle hook., The flagged runtime excerpt includes project paths such as Claude commands and agents in a path list; that excerpt alone does not establish configuration mutation., The native executable is a 78 MB Mach-O containing bounded embedded source candidates, and the offline analysis says those candidates cannot establish loader reachability or rule out other native behavior., A bounded embedded-source excerpt reads several CLI authentication stores, but the inspected evidence does not establish how those values are used or sent. ## Affected versions and remediation This report applies to @reason-machines/cli-darwin-x64@0.2.449. - Review the evidence and your use of @reason-machines/cli-darwin-x64@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.
