According to the docs, most operations inherit from self ward-operation, which would take the component-pathname as an input file (and might take others).
I think input file sets are orthogonal to dependency direction. SELFWARD-OPERATION means that (OP COMPONENT) depends on (DIFFERENT-OP COMPONENT), like how (LOAD-OP LISP-SOURCE-FILE) depends on (COMPILE-OP LISP-SOURCE-FILE). That doesn't mean that (LOAD-OP LISP-SOURCE-FILE) takes COMPONENT-PATHNAME as an INPUT-FILE.
This is what I see in the source, but I haven't had enough time to read it over carefully (or really, at all):
``` ;; An action with a selfward-operation by default gets its input-files from the output-files of ;; the actions using selfward-operations it depends on (and the same component), ;; or if there are none, on the component-pathname of the component if it's a file ;; -- and then on the results of the next-method. (defmethod input-files ((o selfward-operation) (c component)) `(,@(or (loop :for dep-o :in (ensure-list (selfward-operation o)) :append (or (output-files dep-o c) (input-files dep-o c))) (if-let ((pathname (component-pathname c))) (and (file-pathname-p pathname) (list pathname)))) ,@(call-next-method)))) ```
