+# Regression tests
+
+Run each runtime tool on a fixed clip (`sample.wav`, ~6 s) and diff the output against
+the frozen golden in `golden/`. Catches regressions in the ggml graphs, the FSMN-VAD
+state machine, the CIF predictor and CTC decode.
+
+## Run
+```bash
+# from runtime/llama.cpp/, after building (cmake --build build):
+./tests/run_regression.sh              # VAD (tiny model auto-fetched) + any tool whose GGUF is already local
+RUN_FULL=1 ./tests/run_regression.sh   # also download the ASR GGUFs from Hugging Face and test every tool
+```
+`BIN_DIR` / `MODELS_DIR` override where binaries and GGUFs are found. Exit code is
+non-zero if any test fails; tools with no binary or no model are skipped.
+
+## Golden
+Captured on Linux x86-64 (the reference platform) with the f16 GGUFs published at
+`FunAudioLLM/*-GGUF`. Update a golden file only with a deliberate, reviewed output change.
