The page is 724 lines of chronological record across 16 sections, several of them superseded readings kept for their reasoning. A reader arriving fresh had to read all of it to know what is currently true. Adds a summary table at the top covering the twelve questions the page answers, each with its confidence, plus the wave-enumeration recipe and an explicit note that everything below is history. Also names the four mistakes recorded below so a reader knows they are deliberate rather than stale.
