Why flagged

The PKGBUILD downloads a prebuilt AppImage (containing app.asar and unpacked native modules) from a legitimate GitHub release with a pinned checksum, which is standard practice for Electron app packaging in AUR. However, there are two notable concerns: (1) The Live2D Cubism Core JS library is fetched from cubism.live2d.com with 'SKIP' for its checksum, meaning any change to that file on the CDN would go undetected — this is a real supply-chain risk since it is executed JavaScript loaded into the Electron app. (2) The app.asar itself is a prebuilt binary blob whose contents cannot be easily audited. The GitHub source has a proper checksum, so that part is pinned. The SKIP checksum on the live2dcubismcore.min.js is the primary concern — it is an executed script from a third-party CDN with no integrity verification, which constitutes a genuine medium-severity supply-chain risk.
