For non-fiction authors stuck in revision hell where every fix breaks something else. This diagnostic maps the four levels where non-fiction operates: thesis, structure, evidence, and pedagogy. It walks you through figuring out whether your problem is a weak central argument, broken chapter logic, insufficient support, or reader comprehension issues. The real value is in cascade detection, helping you see how changing your thesis invalidates chapters or how new evidence accidentally raises the bar for your other claims. Think of it as a dependency mapper for book arguments. Worth using when beta readers report confusion or when you sense your revisions are making things worse instead of better.
