# R8/ProGuard keep rules for Tane (org.comunes.tane).
#
# R8 is enabled for release builds (see build.gradle.kts). It shrinks/optimizes
# the Java/Kotlin bytecode and can break code reached only via reflection or JNI
# — the native plugins below load their Java classes from C, so R8 can't see the
# references and would strip/rename them. Keep them explicitly. Start
# conservative; trim only after a release smoke test proves a class is unused.

# --- Flutter engine & embedding ---
# Do NOT blanket-keep io.flutter.** : that pins io.flutter.embedding.engine.
# deferredcomponents.PlayStoreDeferredComponentManager, which references the
# proprietary com.google.android.play.core.* (SplitInstall/SplitCompat) API and
# makes F-Droid's scanner reject the APK. Tane doesn't use deferred components,
# so let R8 shrink that unused manager away (removing the Play Core references).
# JNI-critical embedding classes (FlutterJNI, etc.) are kept by the Flutter
# embedding AAR's own bundled consumer ProGuard rules, so this stays safe.
