## 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:** 0.2.430
- **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 show no install hook, and the agent-configuration match is part of sandbox write-protection logic. The native executable's behavior remains materially unresolved, so a clean or malicious verdict is not supported by the available source inspection.

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

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 confirmed in the inspected source. The bundled native CLI remains unresolved because the available offline analysis contains bounded embedded-source candidates and cannot establish their reachability or rule out other native behavior.

- **Trigger:** Invoking the CLI runs the bundled darwin-arm64 executable.

- **Impact:** The executable's potential effects remain undetermined.

- **Evidence paths:** .lpm-inspection-T4CFjH/0-fdb8a3ce9108.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-19T07:04:04.050Z

### AI review details

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

- **Mechanism:** The offline analysis does not establish which embedded native code is reachable or characterize all native behavior.

- **Rationale:** The manifest and flagged JavaScript show no install hook, and the agent-configuration match is part of sandbox write-protection logic. The native executable's behavior remains materially unresolved, so a clean or malicious verdict is not supported by the available source inspection.

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

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 86.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The offline report identifies bin/reason as a 71 MB native executable, but its bounded embedded-source windows cannot establish reachability or rule out other native behavior., The flagged sandbox runtime lists MCP and Claude configuration paths among its built-in write protections.

- **Evidence against:** package.json describes a darwin-arm64 CLI and contains no install lifecycle script., The inspected sandbox-runtime code describes bypassing those write protections as an option for processes trusted with full host filesystem access.

## Affected versions and remediation

This report applies to @reason-machines/cli-darwin-arm64@0.2.430.

- Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.430 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.

sourceBytes=71658016
format=Mach-O Bun embedded source candidates
