When the PS4 reports a user signed in on a controller, the service asks for the user's name and adds it to the status as `user`. The PS4 may not have finished signing the user in by then, so a failed look-up is retried every half second for five seconds. The tile shows the name in place of "Controller N" (the ring keeps the number), and the controller screen reads "Controller 1 · Alex". Names are kept out of the log, since people post logs in bug reports, and they go out cleaned: quotes and backslashes escaped, and control characters or anything that isn't valid UTF-8 replaced, because a browser drops the whole WebSocket on a text frame that isn't valid UTF-8. An Invite panel, opened from a button next to the settings or from the menu, shows the page's address as a QR code for friends to scan. The console makes the code with the QR encoder the app already ships, from the address the page reached it on, and sends the module grid; the page draws it as SVG, so it still needs no libraries. The gamepad picker's tooltip had the same "Controller 1 · Controller 1" doubling the controller screen had; it now names the user too.
