Active ownership confirmatory design
Active ownership confirmatory design is one of 87 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.

Rule. For each year, fetch headers in deterministic rank order until 40 eligible disjoint rows exist or the year is exhausted; freeze the first 40.

Check it yourself
Every figure above is read from /glassbox/active_ownership_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.
