A reply's sources sit behind their count, which opens like a dropdown onto a numbered list with one source to a line, rather than badges wrapped side by side under a count. The count is a details summary with a chevron, and it starts closed, so the sources stay out of the reply's way until asked for. Each row is as wide as its link, in the well's grey, so its hover tint covers the link rather than the line. The list no longer folds past seven, since opening the count already asks for every source; a web search's results still fold. The web UI spec says so, and the message test checks the sources start closed and open to show all ten.
