## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed.

- **Verdict:** Manual Review
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Under Review
- **Threat category:** Unknown
- **Selected version:** 0.2.382
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. 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 inspected runtime excerpt do not establish malicious behavior, but the bundled native executable has material unresolved behavior that the bounded analysis cannot rule out. Manual review is warranted; scanner similarity and binary presence alone are not proof of an attack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 91.0%

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 main native executable remains unresolved because its offline analysis covers only bounded embedded-source windows.

- **Trigger:** Running the bundled CLI executable.

- **Impact:** Unknown until the executable's behavior is adequately analyzed.

- **Evidence paths:** .lpm-inspection-IsYHYA/0-d4033e7b5f75.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T07:06:51.975Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The available analysis does not establish which embedded code is reachable or whether other native behavior exists.

- **Rationale:** The manifest and inspected runtime excerpt do not establish malicious behavior, but the bundled native executable has material unresolved behavior that the bounded analysis cannot rule out. Manual review is warranted; scanner similarity and binary presence alone are not proof of an attack.

- **Files touched:** bin/ara

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 91.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The package manifest identifies this as a Darwin x64 Reason CLI binary package., The native executable analysis is limited to bounded embedded-source windows and cannot establish loader reachability or rule out other native behavior., The inspected runtime source includes project paths such as .mcp.json, .claude/commands, and .claude/agents; the excerpt alone does not establish an attack.

- **Evidence against:** The manifest has no lifecycle scripts and describes the package as a platform-specific native CLI., The bounded embedded source includes validation for Reason service MCP URLs, but that does not resolve the native executable's full behavior.

## Affected versions and remediation

This report applies to @reason-machines/cli-darwin-x64@0.2.382.

- Review the evidence and your use of @reason-machines/cli-darwin-x64@0.2.382 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.
