Is the

ExtractedArchive

directory-name stable? As in, will the resulting uncompressed data be nested in a folder? Or is that strictly dependant on how it was compressed in the first place?

If you understand archives+`tar` then looking at the code should tell you. Otherwise, playing around in a kept sandbox should tell you.

So, the problem was that I thought I found a case where different archive types behaved differently, which is why I was a bit confused. I need to dig in more before I'm sure though. However, I don't know if it was a situation where the number of files in the archive was 1 vs not 1, or whether we used gz/tar/zip. I was about 40 sandboxes deep yesterday while debugging something else
