## 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:** 0.2.374
- **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 excerpt show no confirmed attack. The required native executable remains materially unresolved by its bounded offline analysis, so the source evidence does not support a clean verdict.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

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 established from the inspected source. The package’s native executable remains unresolved because the available offline analysis covers only bounded embedded source windows.

- **Trigger:** Unknown; execution behavior of the native CLI was not resolved by the available analysis.

- **Impact:** No impact was confirmed; native behavior remains undetermined.

- **Evidence paths:** .lpm-inspection-l3IIes/0-5d94eb0ecb7a.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-17T23:58:49.908Z

### AI review details

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

- **Mechanism:** The analysis does not establish whether the embedded source is reachable or whether other native behavior exists.

- **Rationale:** The manifest and flagged JavaScript excerpt show no confirmed attack. The required native executable remains materially unresolved by its bounded offline analysis, so the source evidence does not support a clean verdict.

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 91.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The native executable’s offline analysis is limited to bounded embedded source windows and cannot establish reachability or rule out other native behavior., The flagged JavaScript location contains path-filter helpers over project configuration and command paths; it does not resolve the native executable’s behavior.

- **Evidence against:** The inspected manifest contains package and platform metadata but no lifecycle scripts or declared JavaScript entrypoint., The inspected JavaScript excerpt shows path filtering, not a demonstrated configuration write or credential transfer.

## Affected versions and remediation

This report applies to @reason-machines/cli-darwin-arm64@0.2.374.

- Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.374 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
