This might help:
(mapc #'(lambda (x) (eval `(trace ,x))) asdf::*default-source-registries*)
before you do the call to INITIALIZE-SOURCE-REGISTRY.
IIUC, that will show you what configuration elements are where. But it
doesn't trace the actual search of the directories.
There's a bunch of collector functions in here, but there's also a lot
of unnamed functions and a lot of second-order programming, which makes
tracing it pretty complicated.
If I get a chance tomorrow, I'll set up an example and try to figure out
how to see ASDF actually probing directories.
