## 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:** 0.2.415
- **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 lifecycle scripts, and the inspected runtime excerpt lists agent-related paths as sandbox-protection targets without showing a write. The native CLI's behavior remains unresolved because its offline analysis is bounded and cannot establish reachability or rule out other behavior.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 79.0%

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 from the inspected JavaScript excerpts. The main native executable remains materially unresolved because its analysis is limited to bounded embedded source candidates.

- **Trigger:** Running the packaged native CLI; executable behavior could not be fully determined from the available analysis.

- **Impact:** Potential native behavior cannot be assessed from the bounded analysis, so the package's safety remains unresolved.

- **Evidence paths:** .lpm-inspection-kl7aOH/0-7511c92dd651.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-19T01:28:48.095Z

### AI review details

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

- **Mechanism:** The inspected offline analysis does not establish which embedded source is reachable or what other native behavior may occur.

- **Rationale:** The manifest has no lifecycle scripts, and the inspected runtime excerpt lists agent-related paths as sandbox-protection targets without showing a write. The native CLI's behavior remains unresolved because its offline analysis is bounded and cannot establish reachability or rule out other behavior.

- **Files touched:** bin/reason.exe, bin/runtime/srt/sandbox-runtime.mjs

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 79.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** package.json identifies a Windows ARM64 native CLI package and contains no lifecycle scripts in the inspected manifest., The bundled runtime lists .mcp.json and Claude command and agent paths among sandbox-protection targets; this excerpt alone does not show configuration mutation., The offline analysis covers bounded embedded source candidates from bin/reason.exe and says it cannot establish loader reachability or rule out other native behavior.
