Start in carvel-vendir/pkg/vendir/fetch/archive.go at tryTarWithGzip and inspect how .tar and .tar.gz archives are extracted. Compare its behavior with tar xvf, focusing on links, modes, UID/GID, and other metadata named in the issue. Done means extraction preserves the expected archive contents and metadata for both formats.
