Hi Chris,

Thanks so much for doing this work. You've fixed a pretty painful
design flaw that we've been working around for years. Originally, the
repository protocol was very, very simple. It was based entirely on
VersionInfo and we expected that repositories would use the UUIDs they
contain to store versions. (You'd basically just need #storeVersion
and #versionWithInfo:ifAbsent:). We then found that naming mcz files
with the version name instead of the UUID made it very easy manage
repositories using the OS, and so all the cruft involving version
names and custom RepositoryInspectors grew up to make that viable.

I've loaded your work from the Inbox and find that it works well - all
tests are green and poking around with repository inspectors, loading,
saving etc didn't cause any problems. Nice work!
