The app's CMake configure reads JNI sources generated by library codegen (react-native-edge-to-edge), but the RN Gradle plugin does not declare that dependency. With a warm Gradle cache configureCMake started before codegen and v0.1.12 failed. Run generateCodegenArtifactsFromSchema in a separate Gradle call first; both calls share one daemon.
