## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 16 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.0.0-alpha.43
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The manifest has no install hook, and the flagged process behavior is part of browser management and startup diagnostics. The inspected source did not establish credential theft, hidden command execution, or another concrete attack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 90.0%
- **Started:** 2026-10-24T12:30:35.236Z
- **Finished:** 2026-10-24T12:32:04.754Z
- **Download time:** 1026 ms
- **Static scan time:** 1614 ms
- **AI review time:** 86876 ms
- **Total time:** 89518 ms

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 attack surface was identified in the inspected package source.

- **Trigger:** A user invokes the browser tool through its exported runtime API.

- **Impact:** The inspected behavior supports browser automation, and no concrete harmful effect was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-24T12:32:04.754Z

### AI review details

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

- **Mechanism:** The runtime checks profile and page bindings before browser operations; process handling supports browser lifecycle management.

- **Rationale:** The manifest has no install hook, and the flagged process behavior is part of browser management and startup diagnostics. The inspected source did not establish credential theft, hidden command execution, or another concrete attack.

### Review decision

- **Verdict:** Clean

- **Confidence:** 90.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest exposes browser-tool entrypoints and lists build and development scripts, with no install lifecycle hook., The runtime checks that browser operations use a page bound to the selected profile., Captured browser process output is used in the browser startup failure path., The inspected dependencies expose port and process registry helpers and schema validation utilities.

- **Evidence against:** The flagged process execution is used for browser management and process inspection; no concrete attack behavior was confirmed.

## Affected versions and remediation
