## 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:** 0.2.395
- **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 agent-related excerpt do not establish malicious behavior. The primary native executable has only bounded analysis, leaving material runtime behavior unresolved, so manual review is warranted.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 88.0%

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 attack was confirmed from the inspected source. The main native executable remains materially unresolved because its analysis covers only bounded embedded-source windows.

- **Trigger:** Unknown; the native executable’s behavior when launched was not fully established by the available analysis.

- **Impact:** Unknown; no concrete attack effect was established.

- **Evidence paths:** bin/reason, .lpm-inspection-iX3G86/0-3dd83d36d9da.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T11:07:50.976Z

### AI review details

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

- **Mechanism:** The available analysis exposes embedded-source candidates but does not establish their reachability or the executable’s other behavior.

- **Rationale:** The manifest and inspected agent-related excerpt do not establish malicious behavior. The primary native executable has only bounded analysis, leaving material runtime behavior unresolved, so manual review is warranted.

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 88.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The host analysis identifies bin/reason as a 72 MB Mach-O executable and contains only bounded embedded-source candidates., The host analysis says those windows cannot establish loader or bytecode reachability or rule out other native behavior., The flagged runtime location lists .mcp.json and agent configuration paths, but that excerpt alone does not establish a configuration change or attack.

- **Evidence against:** package.json describes a darwin-arm64 CLI binary and declares no lifecycle scripts in the inspected manifest., The inspected agent-related excerpt is a list of paths and contains no write operation.

## Affected versions and remediation

This report applies to @reason-machines/cli-darwin-arm64@0.2.395.

- Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.395 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.
