Just to make sure I'm clear here, an "implied branch" is a set of
actual branches that pass a certain collection of tests?

I have an alternative to suggest. What about 
{arch}/=tests-version and {arch}/=tests-data-version . Both meta-deta
files list in which versions one can find tests and test data.

This got me thinking on something that may be related. Test data is likely
to be chock full of binary files, and may be updated often. This screams
for xdelta support.
