## 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 shows a platform-specific native-binary package without install hooks. The primary executable's behavior remains materially unresolved, so the source evidence is insufficient to classify the package as clean or malicious.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 98.0%

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 confirmed. The shipped native executable remains unresolved because its embedded-source analysis is bounded and cannot establish which behavior is reachable.

- **Trigger:** Unknown; the package manifest does not specify an executable entrypoint.

- **Impact:** Unknown; available evidence does not establish the executable's runtime effects.

- **Evidence paths:** .lpm-inspection-CrmqHW/0-d4684a2d5e18.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-23T00:44:39.922Z

### AI review details

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

- **Mechanism:** The offline analysis exposes embedded-source candidates but cannot establish their reachability or exclude other native behavior.

- **Rationale:** The manifest shows a platform-specific native-binary package without install hooks. The primary executable's behavior remains materially unresolved, so the source evidence is insufficient to classify the package as clean or malicious.

- **Files touched:** bin/reason.exe

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 98.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest defines a Windows ARM64 native-binary package and contains no lifecycle hooks or JavaScript entrypoints., The verified analysis identifies an 86 MB PE executable but contains only bounded embedded-source candidates; it says those candidates cannot establish reachability or exclude other native behavior.

## Affected versions and remediation

This report applies to @reason-machines/cli-win32-arm64@0.2.541.
