Platforms

Android

• minSdk 24, compileSdk 37 (AAR metadata from Compose 1.12 and this library).
• JNI libraries ship inside the AAR. consumer-rules.pro on the KMP AAR and the JNI AAR keeps JNI entry points; the app does not add extra keep rules.
• Do not add a second copy of libsweeteditor.so.

Desktop (JVM)

• JVM 11+.
• First load extracts Core + compose JNI from JAR resources into a per-user cache, then System.load.
• Keep rules ship in the JAR under META-INF/proguard/ and META-INF/com.android.tools/r8/. Compose Desktop's ProGuard task does not scan dependency JARs; include those files if you enable release minification.

iOS

• cinterop statically links libsweeteditor.a (and libsweetline.a for highlight) for iosArm64 and iosSimulatorArm64.
• The host Xcode project must not add -lsweeteditor, -lsweetline, or -liconv. SweetLine embeds LC_LINKER_OPTION -liconv.
• Device and simulator slices are different archives. A device object in the simulator klib fails with “built for iOS while targeting iOS-simulator”.

Web (JS and Wasm)

• The library injects sweeteditor_web_abi.js / sweetline_web_abi.js and loads *_c_abi.{js,wasm} from Compose resources (files/).
• Host index.html does not need a manual script tag (0.1.1+).
• NativeBridge.isAvailable becomes true after the C ABI module is ready. SweetEditor waits up to ~1800 frames, then shows a load error.
• Keep Compose 1.12.1 so Skiko exports nGetUnresolvedCodepointsCount.

Shared constraints

All targets talk to the same C API. Line/column are 0-based. Colors are packed ARGB Int (0xAARRGGBB).
