Without one of HF's default query files at the repo root (config.json,
config.yaml, hyperparams.yaml, params.json, meta.yaml), the Hub doesn't
register any downloads — HfApi reported 'downloads: 0' for this repo
because Pipeline.from_pretrained() pulls weights/*.safetensors but
never touches a recognised query file.
Adding config.json fixes the counter AND provides a single discoverable
metadata file:
- model_type, library_name, base_model, pipeline_tag
- the 4 sub-architectures (DP / TE / VE / vocoder)
- 31 supported languages (ISO codes)
- 13 voices (10 presets + 3 custom blends)
- inference config (5 Euler steps, CFG 4x cond - 3x uncond, default seed 99)
- measured RTF on M4 and M3 Ultra
- license trail (OpenRAIL-M weights + Apache-2.0 code)
