## 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:** 0.1.52
- **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 lifecycle and runtime source shows package-related setup behavior, with no confirmed malicious action. The required PDF binary remains unresolved, so the package cannot be marked clean from this inspection.

## 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 concrete attack was identified in the inspected executable source. The flagged PDF remains unresolved because its binary structure and contents could not be verified.

- **Trigger:** Package installation runs the postinstall hook; the PDF’s activation, if any, is unverified.

- **Impact:** No attack impact is established; the unresolved binary prevents a clean determination.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-10-16T05:23:21.070Z

### AI review details

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

- **Mechanism:** The hook copies named configuration files and two logos; inspected source does not name the PDF, but its contents remain unexamined.

- **Rationale:** The inspected lifecycle and runtime source shows package-related setup behavior, with no confirmed malicious action. The required PDF binary remains unresolved, so the package cannot be marked clean from this inspection.

- **Files touched:** src/postinstall.js

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 76.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest runs src/postinstall.js after installation., The postinstall hook’s asset-copy list names two logo files; it does not name the flagged PDF., The package also exposes build configuration and a Playwright helper that detects a local Chromium executable., The flagged PDF is a required binary review path, and its structure or embedded content remains unverified.

- **Evidence against:** The postinstall hook copies a fixed set of configuration files and named logos into the consumer project., The Playwright install helper runs only when invoked directly.
