+# However, the standalone ProGuard 7.7.0 that compose-jb invokes does NOT
+# auto-import library `META-INF/proguard/*.pro` consumer rules from arbitrary

+# and member methods on `BundledSQLiteDriver` itself. Because those JVM symbols
+# are referenced only from native code, ProGuard removes them as unused; the
+# native loader then crashes with `NoSuchMethodError: ... name or signature does
+# not match`. Keep the whole driver package — it's small and entirely needed at
