## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified. The reviewed network call retrieves archive content for an explicitly selected custom renderer.

- **Trigger:** A selected archive entry uses a custom renderer and that renderer requests its binary content.

- **Impact:** No unrelated data transfer, persistence, or system mutation was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-10T06:27:32.217Z

### AI review details

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

- **Mechanism:** The viewer fetches the entry source and returns its response body as a blob.

- **Rationale:** The manifest and entry-point evidence show a normal media viewer package, and the required stylesheet contains presentation rules. The archive fetch is tied to custom rendering of selected content; no malicious behavior was found in the inspected source.

- **Files touched:** dist/cjs/viewers/archiveSidebar/archive-viewer-base.js

### 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 identifies the package and version, with CommonJS and ES module entry points., The required CSS contains ordinary layout and typography rules., The CommonJS entry point exports the media viewer loader., Archive preview fetches the selected entry source only when a custom renderer requests its binary content.
