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them superseded readings kept for their reasoning.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.
