## 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:** 0.2.371
- **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 inspected JavaScript do not establish malicious behavior, but the package’s primary native executable cannot be cleared from the bounded offline analysis. Manual review is warranted because its relevant behavior and activation remain unresolved.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 76.0%

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 identified in the inspected source. The primary native executable remains materially unresolved because its bounded embedded-source analysis does not establish reachability or exclude other native behavior.

- **Trigger:** Unknown; activation of the native executable was not established by the available source analysis.

- **Impact:** No confirmed impact; native executable behavior remains unresolved.

- **Evidence paths:** .lpm-inspection-u1fY1I/0-d96bc45ce17d.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-17T21:03:06.737Z

### AI review details

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

- **Mechanism:** No confirmed attack mechanism. The offline analysis contains bounded embedded-source windows but cannot establish which code is loaded or executed.

- **Rationale:** The manifest and inspected JavaScript do not establish malicious behavior, but the package’s primary native executable cannot be cleared from the bounded offline analysis. Manual review is warranted because its relevant behavior and activation remain unresolved.

- **Files touched:** bin/ara

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 76.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The package manifest identifies this as a Darwin x64 native CLI and contains no lifecycle hooks or JavaScript entrypoint., The flagged JavaScript location lists configuration-file names and does not establish an attack., The primary executable is a Mach-O binary; its bounded embedded-source analysis cannot establish code reachability or rule out other native behavior., The inspected embedded source validates Reason service URLs and identifies a legacy Reason MCP configuration, but does not establish whether the relevant native code runs or how it is activated.

- **Evidence against:** The manifest contains package identity and platform metadata, with no declared install-time scripts., The inspected configuration excerpt concerns named files and directories; no concrete attack behavior is established there.
