 - **Raw JSON endpoint handlers** mirroring the upstream llama.cpp HTTP server (`/completions`, `/v1/completions`, `/embeddings`, `/infill`, `/tokenize`, `/detokenize`).
 - **Two runnable HTTP server modes, one fat-jar entry.** The fat jar's `Main-Class` is `ServerLauncher`, which dispatches on the `--jllama-openai-compat` flag. Without it, `java -jar …-jar-with-dependencies.jar -m model.gguf --port 8080` runs the full upstream llama.cpp server (embedded **WebUI**, every llama-server flag forwarded) hosted inside `libjllama` over JNI — no separate `llama-server.exe`. With it, `java -jar … --jllama-openai-compat --model model.gguf --port 8080` runs the Java-transport, zero-extra-dependency **OpenAI-compatible** server (`OpenAiCompatServer`, streaming SSE) instead. Both are also runnable directly by class name via `java -cp … net.ladenthin.llama.server.{NativeServer,OpenAiCompatServer}`.
 - **Model metadata** access (`getModelMeta()`) and **server management** (metrics, slot save/restore, runtime thread reconfiguration).

+- **GGUF metadata inspection** without loading the model (`GgufInspector` — pure Java, reads header + key/value table only, big-endian aware).
+- **Multi-model router mode** (`--models-dir` + per-request model selection, managed via the typed `RouterClient`) and **attach mode** (`NativeServer(LlamaModel, ...)` serves an already-loaded model over the full upstream HTTP frontend — one copy of the weights).

-- **Expand PIT mutation-testing scope.** PIT is wired in `pom.xml` and runs on every CI build (in the `test-java-linux-x86_64` job) with `<mutationThreshold>100</mutationThreshold>`, but `<targetClasses>` is currently narrowed to a single class (`Pair`). The intent is to exercise the wiring and gate against regressions on that single class today; widen `<targetClasses>` incrementally as additional classes reach mutation-test parity. Final target: `<param>net.ladenthin.llama.*</param>` matching the streambuffer pattern.
