tests/__init__.py keeps a run offline, its scratch under tmp/ and its installer cache its own, but only discover -s tests -t . imported it. discover tests ran with RETROBIOS_OFFLINE unset, scratch on the /tmp tmpfs and the user's real installer cache, the setting in which e2e fixtures had written into the shared .cache/large. Every test module now imports the package first, and a test fails on a module that does not. test_verify_listing.py took its line with the previous commit.

"""Every pack member is bytes the collection recognises.

A member whose sha1 and md5 matched nothing was counted `untracked` with
|

zero errors and the pack passed, so bytes altered while the ZIP was written
|
|
went unseen. Archives the builder assembles (MAME clone sets) are

recognised by their members.
