* test: numerical regression harness (frozen golden vs ggml/VAD/CIF/CTC output)
Adds tests/ — runs each runtime tool on a fixed 6 s clip and diffs against frozen
golden output, catching regressions in the ggml graphs, the FSMN-VAD state machine,
the CIF predictor and CTC decode.
- tests/run_regression.sh: auto-detects which tools are built; VAD model is auto-fetched
(1.7 MB), ASR GGUFs tested when present or with RUN_FULL=1 (downloads from HF).
Non-zero exit on any mismatch. BIN_DIR/MODELS_DIR overridable.
- tests/sample.wav (~6 s) + tests/golden/*.txt: golden captured on Linux x86-64 with the
f16 GGUFs from FunAudioLLM/*-GGUF.
Verified locally: all present tools PASS; default mode fetches VAD + skips absent models.
* test: golden as text (binaries now detok in-process; merge after in-binary-detok)
* test: fix sensevoice golden (correct transcription text)
