It's done at the source level, just the same way that we've been manually
checking vendor/ subdirectories up until now (except better, since we can
scan and checksum more easily). And that is done when generating the
SRC_URI. Again, I'm only talking about go here, since that is where I spend
most of my time in meta-virt. So this may be completely wrong for other
languages or use cases I haven't run into.

I use the SRC_URI, since I also use the fetcher prefix/subdir to position the
clones where they will be picked up for the build, and that means the
dependencies are very visible and part of a normal recipe hash/sstate/etc,

But if similar functionality was possible via a language specific lock file,
I wouldn't object.
