Developed native Zstandard asset decompression support for the Aqua backend in the jdx/mise repository, enabling seamless handling of zst-compressed assets within the asset installation workflow. The work involved implementing un_zst decompression and integrating it into the existing asset pipeline, thereby expanding compatibility with additional archive formats. Leveraging Rust for backend development, the solution focused on robust file compression and decompression techniques while maintaining deployment flexibility across environments. No bugs were reported or fixed during this period, reflecting a focused and well-scoped feature delivery. The contribution enhanced system administration capabilities by broadening supported asset formats in production workflows.
