## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified. The reviewed fetch supports archive preview rendering through a selected custom renderer.

- **Trigger:** A consumer renders an archive entry using a custom renderer that requests its binary content.

- **Impact:** The inspected behavior supplies preview data; no separate malicious effect was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-10T06:28:11.948Z

### AI review details

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

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

- **Rationale:** The required CSS finding is styling, and the flagged fetch is part of the archive viewer's custom-renderer data flow. The inspected source establishes no malicious behavior.

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

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest identifies the package and its normal viewer entry points., The required CSS finding contains presentation rules., The archive fetch is exposed as binary content to a selected custom renderer.

- **Evidence against:** The inspected fetch is tied to archive preview rendering; no unrelated recipient or credential forwarding is shown.
