## 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:** 0.2.378
- **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 package manifest has no lifecycle hooks, and the flagged JavaScript excerpt does not establish malicious behavior. The main native executable is only partially analyzed; embedded credential-reading code and the analysis limits leave material runtime behavior unresolved, so manual review is appropriate.

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

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 is confirmed from the inspected excerpts. The primary native executable has unresolved behavior, including embedded code that reads local coding-agent credentials.

- **Trigger:** Running the native CLI may activate the embedded code; its complete activation path was not established.

- **Impact:** Potential credential exposure cannot be ruled out from the available analysis.

- **Evidence paths:** .lpm-inspection-aF8sFv/0-62535871a83d.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T04:52:26.610Z

### AI review details

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

- **Mechanism:** The limited offline analysis exposes credential-reading code but does not establish all callers, transfers, or other native behavior.

- **Rationale:** The package manifest has no lifecycle hooks, and the flagged JavaScript excerpt does not establish malicious behavior. The main native executable is only partially analyzed; embedded credential-reading code and the analysis limits leave material runtime behavior unresolved, so manual review is appropriate.

- **Files touched:** bin/ara

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 86.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** package.json identifies this as the platform-specific Reason CLI binary package., The flagged runtime excerpt lists project configuration paths, but the inspected location does not establish an attack., The offline analysis says its bounded embedded source windows cannot establish whether all native behavior is reachable or absent., Embedded source candidates include code that reads local coding-agent credentials; the available windows do not resolve the complete activation and transfer behavior.
