## 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:** 0.1.47
- **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 install hook performs package-related project setup, and no concrete attack behavior was established. The bundled PDF remains unresolved because trusted offline analysis could not determine its structure or behavior, so manual review is warranted.

## 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 confirmed attack was identified in the inspected source. The included PDF remains unresolved because available offline analysis could not inspect its structure or executable behavior.

- **Trigger:** The postinstall hook runs automatically during installation; the PDF is not among the assets it copies.

- **Impact:** No concrete attack impact was confirmed; the unresolved artifact prevents a clean determination.

- **Evidence paths:** package.json, src/postinstall.js, assets/image/jews-support-a-free-palestine-poster.pdf, .lpm-inspection-Il8ecR/0-163ed93a16b3.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-15T06:50:39.071Z

### AI review details

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

- **Mechanism:** The hook copies named configuration and pipeline files into the consumer project. No inspected source loads the PDF, but its behavior remains undetermined.

- **Rationale:** The inspected install hook performs package-related project setup, and no concrete attack behavior was established. The bundled PDF remains unresolved because trusted offline analysis could not determine its structure or behavior, so manual review is warranted.

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 82.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** package.json automatically runs src/postinstall.js after installation., The postinstall hook copies named configuration and pipeline files into the consumer project., The hook’s asset copy list contains only the two logo files., The included PDF’s trusted offline analysis could not determine its structure or executable behavior.

- **Evidence against:** Inspected source showed no confirmed credential transfer, network send, or AI-agent control-surface mutation., No inspected source loads the PDF; the postinstall hook copies only the listed logos.
