intentumdiff-java

The thin Java binding for the IntentumDiff engine (intentumdiff-core), built on java.lang.foreign (FFM): downcalls to the engine's stable C ABI (intentumdiff_call / intentumdiff_free), zero functional work in the binding.

try (IntentumDiff engine = IntentumDiff.load(Path.of(lib))) {
    String envelope = engine.callRaw("version", "[]");
}

Build + smoke (JDK 21 uses FFM as preview; final from JDK 22):

javac --release 21 --enable-preview -d out src/dev/intentumdiff/*.java
java --enable-preview -cp out dev.intentumdiff.Smoke $INTENTUMDIFF_CORE_LIB

Scaffold status: raw-envelope API (no JSON dependency yet); a typed layer lands as the binding grows. Authored fresh for the #82 split; the monorepo (buchochelliq-labs/intentumdiff) remains the archive of record. License: MIT.
