## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 29 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:** 0.5.2
- **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 manifest has no install-time lifecycle hook, and the older self-dependency release also uses prepublishOnly. Review remains unresolved because the declared playwright-core dependency is loaded by browser functionality but its source was unavailable for inspection.

## 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 concrete attack was established in the inspected source. The behavior of a declared dependency remains unresolved.

- **Trigger:** The command-line program runs when invoked; browser functionality dynamically loads playwright-core.

- **Impact:** The available evidence does not establish an attack or its impact.

- **Evidence paths:** package.json, dist/bin.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-22T17:30:25.958Z

### AI review details

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

- **Mechanism:** The dependency source was not available in the prepared snapshot, so its behavior could not be assessed.

- **Rationale:** The inspected manifest has no install-time lifecycle hook, and the older self-dependency release also uses prepublishOnly. Review remains unresolved because the declared playwright-core dependency is loaded by browser functionality but its source was unavailable for inspection.

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 78.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The package declares playwright-core as a dependency, and the command-line bundle dynamically imports it for browser functionality; its source was unavailable for inspection in this snapshot., The manifest defines prepublishOnly, with no install-time lifecycle hook shown.

- **Evidence against:** The inspected older self-dependency manifest also defines prepublishOnly rather than an install-time hook.

## Affected versions and remediation

This report applies to tnega@0.5.2.

- Review the evidence and your use of tnega@0.5.2 before allowing it. Restrict the permissions described in this report.
