## 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:** 0.1.42
- **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.

Inspected source shows an install hook for project setup and a Playwright helper, with no confirmed attack behavior. The bundled PDF’s binary contents remain unresolved, so the review cannot establish that it is harmless.

## Security analysis

### Published attack-surface review

- **Summary:** No attack was established in the inspected source. The bundled PDF remains unresolved because its contents could not be assessed.

- **Trigger:** The manifest activates the postinstall hook when the package is installed; no inspected source shows that hook loading the PDF.

- **Impact:** No concrete harmful effect was identified; the unresolved PDF prevents a clean verdict.

- **Evidence paths:** assets/image/jews-support-a-free-palestine-poster.pdf

- **Review source:** ai\_review

- **Reviewed:** 2026-10-13T23:46:34.410Z

### AI review details

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

- **Mechanism:** The inspected hook copies named configuration, pipeline, and logo files. The PDF is absent from its asset list, but its binary contents were not verified.

- **Rationale:** Inspected source shows an install hook for project setup and a Playwright helper, with no confirmed attack behavior. The bundled PDF’s binary contents remain unresolved, so the review cannot establish that it is harmless.

- **Files touched:** package.json, src/postinstall.js, assets/image/jews-support-a-free-palestine-poster.pdf

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 78.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest runs src/postinstall.js during installation., The inspected install hook copies only named configuration, pipeline, and logo files; the PDF is not in its asset list., The Playwright config helper locates a system Chromium executable, and its install command runs only when invoked directly.

- **Evidence against:** No concrete attack behavior was established in the inspected executable source., The PDF’s contents and role could not be resolved from the available artifact information.
