amethyst/desktopApp/compose-rules.pro

# ProGuard rules consumed by Compose Multiplatform's `proguardReleaseJars`
# task (see `compose.desktop.application.buildTypes.release.proguard` wiring
# in build.gradle.kts).
#
# Strategy mirrors the Android (mobile) module's `amethyst/proguard-rules.pro`:
#
#   - shrink:    ON   (size win, removes whole unused classes, no renames)
#   - optimize:  ON   (speed win; one bridge-generating sub-pass disabled below
#                       because ProGuard's specialized return-type bridges trip
#                       the JVM verifier on okio — R8 doesn't hit this)
#   - obfuscate: OFF  (via `-dontobfuscate`; every native library we ship
#                       resolves Java callbacks by *class name* through JNI
#                       `FindClass` / `GetMethodID`. Renaming breaks them.)
#
# The Android module solved the exact same JNI-rename problem with:
#
#     -dontobfuscate
#     -keepnames class ** { *; }
#     -keep enum ** { *; }
#
# Plus per-library `-keep` rules for JNA, libsodium, libscrypt, and the
# first-party (`com.vitorpamplona.**`) JSON-mapped types. We replicate that
# verbatim here, then add desktop-only rules for Jackson, VLCj, OkHttp,
# and SLF4J that the mobile build does not need (those code paths are
# Android-stripped on mobile but compiled on desktop).
