## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified. The inspected network call retrieves a blob from the selected archive entry for a custom renderer.

- **Trigger:** A consumer renders an archive and selects an entry, with the binary-content callback used by a custom renderer.

- **Impact:** The inspected behavior supports displaying archive contents; no credential collection, unrelated network destination, or system mutation was identified.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-10T06:28:42.595Z

### AI review details

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

- **Mechanism:** The viewer reads the archive entry into a blob and exposes its object URL or fetches that URL to return the blob.

- **Rationale:** The package manifest identifies compiled viewer entrypoints, and the required CSS finding is ordinary styling. The flagged archive code operates on selected archive content; inspection found no concrete 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 points to compiled viewer entrypoints and lists CSS as a side effect; the required CSS file contains ordinary styling rules., Archive entry loading reads a selected entry's blob and creates a browser object URL for display., The custom renderer's binary-content callback fetches the archive entry source and returns its blob.
