## 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:** 0.2.437
- **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 JavaScript helper includes sandbox protections, and the manifest shows no install lifecycle hook. The native executable’s bounded embedded-source analysis exposes credential-handling candidates but cannot establish their reachability or destinations, so the behavior remains unresolved.

## Latest scan

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, but the shipped native CLI contains behavior that could not be fully resolved from its bounded embedded-source analysis.

- **Trigger:** Running the packaged native CLI may activate embedded code; the available analysis does not establish its loader or call paths.

- **Impact:** Whether credentials or other data are transferred, and under what user configuration, could not be determined from the inspected evidence.

- **Evidence paths:** bin/reason, .lpm-inspection-t2AHjN/0-1fd4b3215e80.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-19T09:14:10.669Z

### AI review details

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

- **Mechanism:** Embedded-source candidates include credential discovery and local-login handover, but their reachability, callers, and data destinations remain unresolved.

- **Rationale:** The inspected JavaScript helper includes sandbox protections, and the manifest shows no install lifecycle hook. The native executable’s bounded embedded-source analysis exposes credential-handling candidates but cannot establish their reachability or destinations, so the behavior remains unresolved.

- **Files touched:** bin/reason, bin/runtime/srt/sandbox-runtime.mjs, .lpm-inspection-t2AHjN/0-1fd4b3215e80.txt

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 68.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest identifies this as a Darwin ARM64 native-binary package and lists bin among its published files., The runtime helper lists .mcp.json and Claude command and agent directories among protected paths; this excerpt does not establish a write to them., The inspected native analysis contains bounded embedded-source candidates and explicitly says they do not establish loader reachability or rule out other native behavior., One embedded candidate gates local-login handover on localLogins being true, but the available window does not establish who sets that option or whether the code is reachable., Another embedded candidate reads credentials from the macOS keychain and local authentication files; the inspected evidence does not resolve their callers or destinations.

- **Evidence against:** The inspected manifest has no lifecycle-script declarations., The static fingerprint and behavior labels are hints; the inspected source does not establish concrete attack behavior.
