When the desk side-loads the APK
The betinia editorial desk treats the APK install as a side-load-only task. The desk only uses the operator's verified APK portal and never a third-party mirror, and only side-loads when the Play Store listing is unavailable in the reader's region or when the operator has published the APK as the primary install path.
The desk confirms four facts before installing the APK: the URL bar reads the operator's verified APK domain; the APK file name matches the operator's published file name; the APK digital signature matches the operator's published fingerprint; and the install-time permission list is restricted to camera and storage.
