+// text page is sent as text, with its image only when the reader was unsure of it. The text is the page's
+// lines without the ones that repeat on most pages (headers, footers). The gateway is asked for

+// request, so a line's page is the question's and never the model's claim, and a page that changed is

+// comparison that folds whitespace, case and diacritics and nothing else, on the page it was asked
+// about. A line whose quote is not there is kept as `needs_review`; it is neither dropped nor trusted,
+// and when the model was shown the page image the line says its quote may come from the image and must
+// be checked against it. A verified line carries the reader's block id and that block's box.
