## 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:** 0.2.522
- **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 has no install lifecycle hook, and the inspected fragments do not establish an attack. The required native executable review remains incomplete, so the source evidence does not support a clean verdict.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-10-22T10:26:21.444Z

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 excerpts. The shipped native executable’s behavior remains unresolved because its offline analysis contains only bounded embedded-source candidates.

- **Trigger:** Running the packaged CLI would activate the native executable; its complete behavior is not established by the available analysis.

- **Impact:** Unknown; the inspected evidence does not establish malicious behavior or its absence.

- **Evidence paths:** .lpm-inspection-1ugDRZ/0-a5e292657bc1.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-22T10:27:16.067Z

### AI review details

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

- **Mechanism:** The analysis exposes partial embedded source, including a child\_process import, but does not establish reachability or cover other native behavior.

- **Rationale:** The manifest has no install lifecycle hook, and the inspected fragments do not establish an attack. The required native executable review remains incomplete, so the source evidence does not support a clean verdict.

- **Files touched:** bin/reason

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 91.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** package.json identifies this as a Darwin ARM64 native CLI package and contains no lifecycle script., The verified offline analysis identifies bin/reason as a 71 MB Mach-O executable and says its embedded-source windows do not establish loader reachability or rule out other native behavior., An embedded fragment imports child\_process, but the bounded excerpt does not establish how all native behavior is activated.

- **Evidence against:** The inspected manifest shows no install-time lifecycle hook.

## Affected versions and remediation
