## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified in the inspected package source.

- **Trigger:** No malicious install-time or import-time trigger was found.

- **Impact:** No malicious impact was identified.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-31T17:58:50.585Z

### AI review details
