You can
(alexandria:hash-table-alist asdf/source-registry::*source-registry*)

or for a higher-level view, you can
(asdf/source-registry:flatten-source-registry)

then again, if you use the newfangled source-registry-cache, you can
find ~/common-lisp -name .cl-source-registry.cache

I'm not sure what you want to debug, so it's hard to tell how to help you.

Also, behavior wrt recursing or not into directory symlinks is not
consistent from one implementation to the next, so beware.

Year 1917. The granddaughter of a Decembrist hears noise coming from the
street and sends a servant to check what's going on. The servant promptly
returns, announcing:
- It's the revolution, Madam !
- Oh my, the revolution ! My grandfather dreamt of the revolution!
And what do those revolutionaries demand?
- They ask that there be no more wealthy people, Madam.
- That is strange... My grandfather wanted that there be no more poor people!
