how does it work?

1. fetch package metadata from rg.store-adguard.net
2. check metadata (if url suffix == microsoft.com or not)
3. download WSA package and check its sha-1 sum
4. unzip .msixbundle (which is just a .zip) and its child .msix (also a .zip) to get vendor.img
5. mount vendor.img and copy libhoudini files
