+# Versioning & Build Rules Addendum
+
+## Build Configuration
+- The app MUST ALWAYS be signed with `schnappix-upload-key.keystore`. This is handled automatically by the custom Expo plugin `withAndroidSigning.js`. Do not modify or remove this plugin.
+- The `schnappix-upload-key.keystore` file is checked into the Git repository. Do NOT delete it, ignore it in git, or change its password (`#O0he7k00O0he7k00!`).
+- The Expo Media Library plugin injects `READ_MEDIA_IMAGES` and `READ_MEDIA_VIDEO` permissions into the Android manifest by default. These are rejected by Google Play for this specific app. To prevent this, the `withRemoveMediaPermissions.js` plugin MUST ALWAYS be included in `app.json`. This plugin forcibly strips these permissions using Android's `tools:node="remove"` directive during compilation. Do not remove this plugin.
