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 shows no install hook, while the bundled runtime excerpt names agent-related project paths without establishing a harmful effect. The primary native executable remains materially unresolved because its offline analysis is limited, so manual review is warranted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-20T07:41:32.985Z - **Finished:** 2026-10-20T07:42:15.711Z - **Download time:** 3866 ms - **Static scan time:** 599 ms - **AI review time:** 38260 ms - **Total time:** 42726 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 was established from the inspected source. The native executable’s behavior remains unresolved because its offline analysis is partial. - **Trigger:** Unknown; executable behavior and the relevant runtime callers could not be fully traced from the available analysis. - **Impact:** Cannot determine from the inspected evidence. - **Evidence paths:** bin/reason, .lpm-inspection-v3h173/0-7c8160e5f8c8.txt, bin/runtime/srt/sandbox-runtime.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-20T07:42:15.711Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package includes a native executable whose embedded source analysis is bounded and does not prove which code is reachable or whether other behavior exists. - **Rationale:** The manifest shows no install hook, while the bundled runtime excerpt names agent-related project paths without establishing a harmful effect. The primary native executable remains materially unresolved because its offline analysis is limited, so manual review is warranted. - **Files touched:** bin/reason, bin/runtime/srt/sandbox-runtime.mjs ### Review decision - **Verdict:** Manual Review - **Confidence:** 90.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest declares a Darwin x64 native binary package and no lifecycle hooks or JavaScript entrypoint., The bundled runtime names project configuration locations including .mcp.json and .claude/agents, but the inspected excerpt does not establish their callers, effects, or consent., The offline analysis of bin/reason contains bounded embedded source windows and says they cannot establish reachability or rule out other native behavior. - **Evidence against:** The manifest identifies the package as a native CLI binary and lists its packaged files. ## Affected versions and remediation This report applies to @reason-machines/cli-darwin-x64@0.2.467. - Review the evidence and your use of @reason-machines/cli-darwin-x64@0.2.467 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.
