Package shape
Android sideload publishes the APK as a single file (matrix single-file). Official SDKs are not APK installers: you must supply a Replacer. Compare and download remain POST check plus a SHA-256 object.
An F-Droid subscription is a separate store listing (fdroid), not the native JSON URL. Index documents:
text
https://updates.example.com/api/v1/projects/myapp/store/fdroid/stable/index-v1.jsontext
https://updates.example.com/api/v1/projects/myapp/store/fdroid/stable/index-v2.jsonConsole: Settings → Store listings → New listing, protocol fdroid. Unknown paths (for example index.xml) are plaintext 404. Official SDKs do not read the F-Droid index.
iPhone enterprise / sideload can use native JSON or a custom drop; that does not replace App Store review. Play / App Store private protocols are out of scope.
