Augmented by anything that the program elects to write to the log file.
 A program can elect to write an "overfull \hbox" message to the log
file even if no overfull \hbox has actually occurred.

Not only do I understand what you mean, I also understand that you fail
to appreciate the difference between "know if an overfull \hbox has
occurred " (which is *TeX's state) and "believe that an overfull \hbox
has occurred" (which is the state of any adjunct program attempting to
determine the state of *TeX's knowledge simply by inspecting the log file).
