## 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:** 0.2.540
- **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 describes a platform-specific native CLI package, while the hash-verified executable analysis is explicitly limited and does not resolve the executable’s behavior. The unresolved native behavior warrants manual review; the inspected evidence does not establish an attack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 93.0%
- **Started:** 2026-10-22T22:15:02.704Z

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 packaged native executable’s behavior remains unresolved because the available analysis contains only bounded embedded-source candidates.

- **Trigger:** Unknown; the executable’s activation and entrypoint behavior are not established by the available analysis.

- **Impact:** Potential behavior of the native executable cannot be determined from the available analysis.

- **Evidence paths:** bin/reason, .lpm-inspection-IvId3H/0-92f75ba32724.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-22T22:15:40.127Z

### AI review details

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

- **Mechanism:** The native executable contains embedded source candidates, including one importing child\_process spawn, but their reachability and effects remain unresolved.

- **Rationale:** The manifest describes a platform-specific native CLI package, while the hash-verified executable analysis is explicitly limited and does not resolve the executable’s behavior. The unresolved native behavior warrants manual review; the inspected evidence does not establish an attack.

- **Files touched:** bin/reason, .lpm-inspection-IvId3H/0-92f75ba32724.txt

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 93.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** package.json identifies this as a darwin-x64 CLI native-binary package and declares files for publication., The verified offline analysis identifies bin/reason as a 78 MB Mach-O Bun executable and says its bounded source windows cannot establish reachability or rule out other behavior., One embedded source candidate imports child\_process spawn, but the available analysis does not establish whether or how that code runs.

## Affected versions and remediation
