They should be. It was my experience that hg does produce reproducible
archives, even without a complexe dance like we do with the git backend.
See commit 76b51f90c0e which purportedly made them reproducible.

I too got that 926208 sha256 here, with two different hg versions: 3.7.3
and 4.8.2.

So, this file was created before the commit that made the archives
reproducible. So, no surprise that the sha256 does not match the
locally-created archive but that from s.b.o.

A full sha1 should be used, rather than a shortened one.

The python-pygame archive was however created after commit 76b51f90c0e...

I too git d5e0a43a4e33.

What machine is pushing the archives to s.b.o. ?
