To answer my own question, they have extracted the decoder from this Google Chrome Labs "Sploosh" project [0], all the sources are here: https://github.com/GoogleChromeLabs/squoosh/tree/dev/codecs/jxl/dec https://github.com/GoogleChromeLabs/squoosh/tree/dev/codecs/... It's under an Apache license, and so the correct license applies. 0: https://squoosh.app https://squoosh.app

There aren't really any sources there, either. From having already spent some time looking into this to track down what, exactly, you should patch should you want to make modifications, it looks like it's using the decoder from the JPEG XL reference implementation, libjxl (which is available under a BSD license): <https://github.com/libjxl/libjxl https://github.com/libjxl/libjxl>
