## 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:** 1.5.1
- **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-time hook, and the flagged bundles contain product-aligned viewer and rendering code. The server’s process execution is limited to its configured, loopback-gated browser opener; the scanner hints do not establish malicious behavior.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 91.0%

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 was identified in the inspected package source. The flagged viewer code supports the editor’s rendering and localization, while the server’s browser-launch behavior is conditional.

- **Trigger:** Using the viewer or starting the server; browser launch additionally requires the configured open setting and a loopback host.

- **Impact:** No harmful file changes, credential transfers, or remote code execution were established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-19T21:09:33.547Z

### AI review details

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

- **Mechanism:** The viewer connects to its current host for live updates. The server can open a ready artifact in a browser and uses a custom command only when configured.

- **Rationale:** The manifest has no install-time hook, and the flagged bundles contain product-aligned viewer and rendering code. The server’s process execution is limited to its configured, loopback-gated browser opener; the scanner hints do not establish malicious behavior.

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest uses a prepublishOnly build command and declares no install, preinstall, or postinstall hook., The viewer loads editor, math-rendering, localization, and diagram modules; its live connection uses the current page’s host., The server’s browser opener requires an explicit open setting and a loopback host; a custom command is used only when configured.

## Affected versions and remediation
