# Runic Gateway Android app — ProGuard/R8 rules (release minify + resource shrink, M6).
#
# The dependency stack ships its own consumer rules that R8 applies automatically:
# Retrofit 2.11, OkHttp 4.12, kotlinx.serialization 1.7 (core), Hilt/Dagger, Coil 2.7.
# The rules below are defensive belt-and-suspenders for the areas full-mode R8 is
# most likely to over-strip in this app: the kotlinx.serialization generated
# serializers and our own @Serializable wire DTOs.

# ── kotlinx.serialization (canonical keep rules) ────────────────────────────
-keepattributes *Annotation*, InnerClasses
-dontnote kotlinx.serialization.**

# Keep the Companion of @Serializable classes so `.serializer()` resolves.
-if @kotlinx.serialization.Serializable class **
-keepclassmembers class <1> {
    static <1>$Companion Companion;
}
-if @kotlinx.serialization.Serializable class ** {
    static **$Companion Companion;
}
-keepclassmembers class <2>$Companion {
    kotlinx.serialization.KSerializer serializer(...);
}
# Keep `INSTANCE.serializer()` of @Serializable objects.
-if @kotlinx.serialization.Serializable class ** {
    public static ** INSTANCE;
}
-keepclassmembers class <1> {
    public static <1> INSTANCE;
    kotlinx.serialization.KSerializer serializer(...);
}
# Keep the synthesized $$serializer classes and their descriptor field.
-keepclassmembers class **$$serializer {
    *** descriptor;
}

# ── Our wire DTOs ───────────────────────────────────────────────────────────
# All request/response models decoded by kotlinx.serialization. Keeping them
# (and their generated serializers) guarantees additive backend fields and
# @SerialName mappings survive minification. DTOs are small, so keeping them
# whole is cheap insurance against a full-mode strip.
-keep @kotlinx.serialization.Serializable class com.runicgateway.app.** { *; }
-keepclassmembers class com.runicgateway.app.data.api.dto.** { *; }

# ── Retrofit service interfaces ─────────────────────────────────────────────
# Retrofit reads method + parameter annotations reflectively; keep our API
# interfaces' generic signatures so return types (suspend .../Call<T>) resolve.
-keep,allowobfuscation interface com.runicgateway.app.data.api.*Api
-keepattributes Signature, Exceptions

# Kotlin metadata is needed for reflection over Kotlin types (serialization/Retrofit).
-keep class kotlin.Metadata { *; }

# ── Tink / EncryptedSharedPreferences (androidx.security-crypto) ─────────────
# Tink references Error Prone compile-only annotations that are absent at runtime;
# they are safe to ignore (they carry no runtime behaviour). Suppresses the R8
# "Missing class com.google.errorprone.annotations.*" errors.
-dontwarn com.google.errorprone.annotations.**
