## 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:** 0.2.412
- **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 and flagged JavaScript location do not establish malicious behavior. The required native executable has only limited offline analysis, which cannot rule out material behavior, so manual review is warranted.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 76.0%

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 in the inspected manifest or sandbox path-policy code. The packaged native executable remains materially unresolved because its bounded source analysis cannot establish which embedded code is reachable or rule out other behavior.

- **Trigger:** Unknown; the manifest defines no install hook or JavaScript entrypoint, and native executable activation was not established by the available analysis.

- **Impact:** Unresolved for the native executable; no specific harmful effect was verified.

- **Evidence paths:** .lpm-inspection-iaW6CK/0-48deadccbfe2.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-19T00:43:47.985Z

### AI review details

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

- **Mechanism:** The package includes a large PE executable, but only bounded embedded source windows were analyzed; those windows do not resolve the executable's full behavior.

- **Rationale:** The manifest and flagged JavaScript location do not establish malicious behavior. The required native executable has only limited offline analysis, which cannot rule out material behavior, so manual review is warranted.

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

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 76.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The inspected manifest identifies a Windows ARM64 CLI binary package and contains no install hook or JavaScript entrypoint., The sandbox runtime lists MCP and agent configuration paths among its protected-path rules; the exact flagged match is part of that path list., The native executable is an 86 MB PE, and the bounded offline analysis says its sampled embedded source cannot establish loader reachability or rule out other native behavior.

- **Evidence against:** The manifest has no install lifecycle scripts, and the flagged JavaScript match is sandbox path-policy code rather than a credential transfer or agent configuration write.

## Affected versions and remediation
