Why this screen exists
A tool that does not show its guesses can produce a book that looks finished and is wrong. A section becomes a paragraph, a numbered list is read as prose, a chapter is missing from the contents.
Here every decision is shown with its evidence before anything is laid out. Lines your document declared are marked declared. Lines worked out from bold text and centering are marked inferred, and you can overrule them.
