This seems to be really well done and I'm looking forward to reading it in more detail, but one thing jumped out at me: one of the keywords used to identify fixes for programming errors is "refactoring". Refactoring doesn't necessarily (and actually shouldn't) refer to fixing a defect. EDIT: The Procedural/Scripting split seems overdetermined. All of the procedural languages have static typing, and all the scripting languages have dynamic typing.

Indeed. Refactoring means restructuring code in a way that doesn't change its external behavior. If we define bug as incorrect external behavior of code, then refactoring excludes bug fixes. Refactoring doesn't necessarily even mean that the original code was structurally bad. When new features are added, code gets more complicated, requiring more abstraction. I like to abstract code via refactoring when we need it, not before. Then refactoring changes good code to good code. It's just that the new situation presents different demands to the code than the old situation.
