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 inspected excerpts show Reason service endpoint validation and a setting-gated local-login handoff, but do not resolve the launcher’s full behavior, defaults, or reachability. Since the package’s executable analysis is explicitly limited and additional executable artifacts are unsupported, the evidence is insufficient to classify the package as clean or malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-18T08:56:11.419Z - **Finished:** 2026-10-18T08:57:03.332Z - **Download time:** 2796 ms - **Static scan time:** 561 ms - **AI review time:** 48556 ms - **Total time:** 51913 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 is established. The native launcher’s behavior remains unresolved because the available inspection covers only bounded embedded-source candidates. - **Trigger:** Running the package’s native CLI launcher. - **Impact:** Undetermined; the available source does not confirm credential theft or agent configuration abuse. - **Evidence paths:** .lpm-inspection-OiLbPf/0-0449d0cccbde.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T08:57:03.332Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected candidates include local-login handoff and legacy agent configuration logic, but do not establish complete launcher behavior or reachability. - **Rationale:** The inspected excerpts show Reason service endpoint validation and a setting-gated local-login handoff, but do not resolve the launcher’s full behavior, defaults, or reachability. Since the package’s executable analysis is explicitly limited and additional executable artifacts are unsupported, the evidence is insufficient to classify the package as clean or malicious. - **Files touched:** bin/ara, bin/runtime/srt/sandbox-runtime.mjs - **Network endpoints:** https://api.ara.so, https://api-staging.ara.so, https://api.reasonmachines.ai, https://staging-api.reasonmachines.ai, https://api.reasonmachines.com, https://staging-api.reasonmachines.com ### Review decision - **Verdict:** Manual Review - **Confidence:** 90.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies this as a Darwin ARM64 package for the Reason CLI., The launcher analysis contains optional local-login handling, but its bounded embedded-source windows do not establish complete behavior or reachability., The launcher is a large native executable, and its remaining behavior is not resolved by the available analysis. - **Evidence against:** The inspected launcher candidate restricts accepted MCP URLs to listed Reason service origins and the expected path., The inspected local-login handoff is guarded by a localLogins setting; the available excerpts do not resolve its effective default and all activation paths. ## Affected versions and remediation This report applies to @reason-machines/cli-darwin-arm64@0.2.388. - Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.388 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.
