## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface was established. Archive retrieval is a viewer feature activated while rendering a selected media archive.

- **Trigger:** A consumer renders the media viewer and selects an archive.

- **Impact:** No unconsented file, credential, command, or configuration action was found.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-11T23:36:01.925Z

### AI review details

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

- **Mechanism:** Fetches a media-client-provided archive URL for browser-side ZIP preview.

- **Rationale:** The inspected manifest has no lifecycle scripts, and the flagged source implements browser media viewing and archive decompression. No concrete malicious behavior was found.

### Review decision

- **Verdict:** Clean

- **Confidence:** 96.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest exposes browser-oriented module entrypoints and contains no install lifecycle hook., The entrypoint only exports the media viewer loader., The flagged archive code obtains a media-client URL and unzips the selected archive in the viewer., The flagged CSS artifact contains presentation rules only.

- **Evidence against:** No child-process, shell, credential-harvesting, persistence, or dynamic-code primitives were found in the inspected distribution., No fixed network endpoint or package-authored exfiltration path was found.

        case 2:
          url = _context.sent;
          reader = new _unzipit.HTTPRangeReader(url);
          _context.next = 3;
