Country Watchlist Dashboard

Country-linked watchlists show a mixed geography of excess CT.gov hiddenness, not one single regional pattern

France leads on adjusted no-results stock, China and Egypt remain strong on ghost excess, South Korea has one of the sharpest black-box rates, and several European portfolios still hold large absolute black-box stock.

France leads on adjusted stock, China and Egypt remain strong on ghost excess, and South Korea stands out on black-box rate even when the raw table is no longer the only lens.

France and China lead the adjusted stock table, with Egypt still prominent despite a smaller linked portfolio.
That mix shows why both size and residual intensity matter.

China and Egypt become even sharper when the focus shifts to ghost protocols rather than missing results alone.
This is the deeper-silence geography table.

The United States still dominates on absolute black-box stock, while France and China remain prominent within the international field.
Black-box stock does not mirror the adjusted excess table perfectly.
