License clarification for 2025 Zipformer CTC model weights

Hi, thanks for maintaining sherpa-onnx.

I’d like to clarify the license for the following model weights:

• sherpa-onnx-streaming-zipformer-ctc-zh-int8-2025-06-30
• sherpa-onnx-streaming-zipformer-ctc-zh-xlarge-int8-2025-06-30

Are these model weights licensed under Apache-2.0?

Also, may third parties redistribute or mirror these model files, for example on ModelScope, while preserving the original model names and attribution?

Thanks for your help.
