# ============================================================================
# Meshtastic Desktop — ProGuard rules for release minification
# ============================================================================
# Open-source project: we rely on tree-shaking (unused code removal) for size
# reduction. Obfuscation is disabled in build.gradle.kts (obfuscate.set(false)).
#
# Key libraries requiring keep-rules (reflection, JNI, code generation):
#   Koin (DI via reflection), kotlinx-serialization (generated serializers),
#   Wire protobuf (ADAPTER reflection), Room KMP (generated DB + converters),
#   Ktor (Java engine + ServiceLoader), Kable BLE, Coil, Compose Multiplatform
#   resources, SQLite bundled (JNI), AboutLibraries.
# ============================================================================

# ---- General ----------------------------------------------------------------

# Preserve line numbers for meaningful stack traces
-keepattributes SourceFile,LineNumberTable,*Annotation*,Signature,InnerClasses,EnclosingMethod,Exceptions

# Suppress notes about duplicate resource files (common in fat JARs)
-dontnote **

# Do not parse/rewrite Kotlin metadata during shrinking/optimization.
# ProGuard's KotlinShrinker cannot handle the metadata produced by Compose
# Multiplatform 1.11.x + Kotlin 2.3.x, causing a NullPointerException.
# Since we disable obfuscation (class names remain stable), metadata references
# stay valid and do not need rewriting. The annotations themselves are preserved
# by -keepattributes *Annotation*.
-dontprocesskotlinmetadata

# ---- Entry point ------------------------------------------------------------

# The serialization plugin generates companion $serializer classes and
# serializer() factory methods that are invoked reflectively.
