"""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.
