## 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:** 0.2.541
- **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 identifies a platform-specific CLI binary package, while the verified native analysis explicitly leaves executable behavior unresolved. No concrete attack is established, so manual review is appropriate.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 94.0%

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 identified in the inspected excerpts. The native CLI executable remains unresolved because the available analysis is limited.

- **Trigger:** Use of the packaged CLI executable; its relevant behavior could not be determined from the available analysis.

- **Impact:** The executable’s behavior cannot be assessed from the available evidence.

- **Evidence paths:** bin/reason, .lpm-inspection-B423FZ/0-b9bff971e6cd.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-22T22:48:58.891Z

### AI review details

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

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

- **Rationale:** The manifest identifies a platform-specific CLI binary package, while the verified native analysis explicitly leaves executable behavior unresolved. No concrete attack is established, so manual review is appropriate.

- **Files touched:** bin/reason, .lpm-inspection-B423FZ/0-b9bff971e6cd.txt

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 94.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** package.json identifies this as a darwin-arm64 Reason CLI binary package., The verified analysis for bin/reason says its embedded source windows do not establish loader reachability or rule out other native behavior., The available analysis is limited to bounded embedded source candidates, so the executable’s behavior remains unresolved.

- **Evidence against:** No attack is established by the inspected excerpts.

## Affected versions and remediation
