Merger announcement confirmatory design
Merger announcement confirmatory design is one of 89 measurements this engine publishes in full. It is regenerated from a real run rather than transcribed, and it is shown here with its own claim boundary so the number and its limits arrive together.

Check it yourself
Every figure above is read from /glassbox/merger_announcement_confirmatory_design.json, the
artifact the engine wrote. Nothing on this page is typed by hand: the page is generated from that
file, so a figure that moves in the artifact moves here and a figure that is not in the artifact
cannot appear here at all.
