What happened?
The transmute documentation is outdated. We now use temporary .tar files to get the complete size before opening a zstd compressor, or a memory buffer if < 10MB based on Python's SpooledTemporaryFile However unlike the pre-conda-package-streaming implementation we never have to extract all the files to disk and back again, so the tar metadata is preserved exactly.
