The person hosting a session, or a file's owner, removes someone from it (right-click their avatar, `collab.removePerson`): they are disconnected and their address can't join that file again while it runs. The list is per computer; a server only a team reaches can also list the files shared from it now for everyone (`team_files`): Home ▸ Online shows that team list for the server in Preferences, a row joins its file, and its links (`figcraft://join?server=…&file=…&team=1`, or the browser build's) carry no secret and stop working with the share.

With `team_files = "edit"` (or `comment`, `view`) everyone who reaches the server sees the files shared from it now (a link of theirs has a join code: Share ▸ Start sharing) and joins them by a team list link, `figcraft://join?server=…&file=…&team=1`, which carries no secret: the server hands out the file's team link while it stays shared (`ResolveTeam`, answered like a join code), and Stop sharing revokes it with the others, disconnecting whoever joined with it. Turning the list off or changing its access refuses the old team links at once. `collab.files {refresh}` asks the server in Preferences for its list (`Admin::Team`; not the public server FigCraft ships with), and Home ▸ Online shows it below your own files: a row joins its file, its menu copies the link for the app or, with the server's `web_url`, for the browser build (`#join=…`). A browser build served beside its server names it with ``, the page's default for sharing, codes and the team list. No accounts: the list is for a server only your team reaches. Tests: `team_tests` (the server and apps over loopback), `code_tests` (links and the browser's driver), `online_tests` (the Online section), `query_tests` (the page's server).
