## 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:** 0.2.457
- **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 inspected manifest has no lifecycle hook, and the cited runtime excerpt does not establish agent-configuration mutation. However, bundled native artifacts remain 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

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 is confirmed from the inspected source. The package includes native executables whose behavior could not be resolved by the available offline analysis.

- **Trigger:** Unknown; potentially when the CLI or bundled background components are invoked.

- **Impact:** Unknown; the available inspection does not establish an attack or its effect.

- **Evidence paths:** .lpm-inspection-ECQYBX/0-d463541b6c11.txt, .lpm-inspection-ECQYBX/1-b7de366aaccd.txt, .lpm-inspection-ECQYBX/2-4077406237f3.txt, .lpm-inspection-ECQYBX/3-3c8d5bae2b40.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-19T22:24:49.297Z

### AI review details

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

- **Mechanism:** The native artifacts are unsupported or only partially analyzed, so their behavior and reachability remain unresolved.

- **Rationale:** The inspected manifest has no lifecycle hook, and the cited runtime excerpt does not establish agent-configuration mutation. However, bundled native artifacts remain materially unresolved, so the source evidence is insufficient to classify the package as clean or malicious.

- **Files touched:** bin/reason, bin/Background/Reason.app/Contents/MacOS/ReasonBackgroundIdentity, bin/Background/Reason.app/Contents/Helpers/ReasonPermissionTile, bin/libreason\_device\_keychain.dylib

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 88.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest declares no lifecycle scripts and identifies this as a darwin-x64 CLI binary package., The cited runtime excerpt lists paths such as \`.mcp.json\` and \`.claude/commands\`; it does not show a configuration write., The offline analysis of \`bin/reason\` contains only bounded embedded-source candidates and says it cannot establish reachability or absence of other native behavior., Offline analysis could not structurally or executably inspect the bundled background executables and keychain library; their behavior remains unresolved.

## Affected versions and remediation
