"""MiMo Audio pipeline topology (frozen).

|
Stage 0: fused thinker+talker — multimodal understanding + text + RVQ codes.
|
|
Stage 1: Code2Wav — RVQ codes → waveform.
|
|
|
|
MiMoAudioConfig inherits from Qwen2Config, so the HF ``model_type`` field
|
|
reports ``qwen2`` — the registry's model_type-based auto-detect can't
|
|
disambiguate. ``hf_architectures`` lets ``StageConfigFactory`` fall back to
|
|
matching ``hf_config.architectures`` instead.
