+# --- Auth0 SDK Gson models ---------------------------------------------------
+# The Auth0 Android SDK deserializes its API responses (Factor,
+# AuthenticationMethod and its sealed subclasses) with Gson via reflection.
+# R8 cannot see those reflective accesses, so without keep rules it strips the
+# fields/classes and Gson fails — surfacing as "a0.sdk.internal_error.unknown".
+# Gson also needs Signature (generic types like List<String>) and the
+# @SerializedName annotations to map JSON keys correctly.
+-keepattributes Signature
+-keep class com.auth0.android.result.** { *; }
+-keepclassmembers class com.auth0.android.result.** { *; }
+# Polymorphic deserializer referenced via @JsonAdapter must be kept by name.
+-keep class com.auth0.android.result.AuthenticationMethod$Deserializer { *; }
+-keepclassmembers class * {
+    @com.google.gson.annotations.SerializedName <fields>;
+}
+
+# --- Public enums passed across the API boundary -----------------------------
+# AuthenticatorType is used as a kotlinx.serialization-backed Compose Navigation
+# argument, which resolves the enum by its fully qualified name at runtime — so
+# the class name must not be obfuscated.
+-keep public enum com.auth0.universalcomponents.domain.model.AuthenticatorType {
+    **[] $VALUES;
+    public *;
