## 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:** 0.2.394
- **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 flagged JavaScript excerpt shows filename and path matching, not agent configuration mutation. The native executable’s behavior remains materially unresolved, so the evidence does not support a malicious verdict or a clean verdict.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 78.0%

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 source. The shipped native CLI remains unresolved because the available analysis covers only bounded embedded-source samples.

- **Trigger:** Running the shipped CLI would activate the native executable; its behavior is not established by the available analysis.

- **Impact:** The CLI’s effects cannot be determined from the inspected evidence.

- **Evidence paths:** .lpm-inspection-bJkP5O/0-966d39869db6.txt, bin/reason

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T10:50:49.031Z

### AI review details

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

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

- **Rationale:** The flagged JavaScript excerpt shows filename and path matching, not agent configuration mutation. The native executable’s behavior remains materially unresolved, so the evidence does not support a malicious verdict or a clean verdict.

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

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 78.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest identifies this as the Darwin ARM64 native CLI package and lists its shipped files., The flagged JavaScript excerpt lists configuration filenames and paths; it does not show a configuration write., The offline analysis identifies bin/reason as a Mach-O executable and says its bounded samples cannot establish the behavior of the full binary.

## Affected versions and remediation

This report applies to @reason-machines/cli-darwin-arm64@0.2.394.

- Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.394 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.
