## 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:** 0.2.396
- **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 JavaScript do not establish malicious behavior; the flagged configuration paths are used as search exclusions. The native executable's limited analysis leaves material behavior unresolved, so manual review is appropriate.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 78.0%

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. The primary native executable has only limited embedded-source analysis, leaving its behavior unresolved.

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

- **Impact:** No specific compromise or harmful effect is established by the inspected source.

- **Evidence paths:** .lpm-inspection-mIq3pQ/0-a27e5f655d74.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T11:25:39.558Z

### AI review details

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

- **Mechanism:** The available analysis contains bounded embedded-source candidates but does not resolve their reachability or cover other native behavior.

- **Rationale:** The manifest and inspected JavaScript do not establish malicious behavior; the flagged configuration paths are used as search exclusions. The native executable's limited analysis leaves material behavior unresolved, so manual review is appropriate.

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 78.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest identifies a Darwin ARM64 CLI package and contains no lifecycle hook or JavaScript entrypoint., The flagged runtime lists MCP and agent configuration paths among files its search helper excludes., The native executable analysis is limited to embedded source windows and says those windows cannot establish loader reachability or rule out other native behavior., An embedded source window contains Cursor MCP configuration handling, but the available analysis does not establish whether its writer is reachable.

- **Evidence against:** The manifest packages the CLI under bin and declares no lifecycle scripts., The flagged runtime uses its configuration path list to build ignore globs for searches, consistent with protecting those files from search.

## Affected versions and remediation
