Everyone signed in right now, and what they're on — so two people don't land on the same skin. Updates every ~20–60s; nobody heard from in 90s drops off the list.
Measured against CS2's real collection list. A skin counts once it has totals captured at any wear. Seed coverage is on SDB.
Nothing drops off this list. It is ordered by what most wants counting — never counted at the top, then oldest first — so a collection you have just finished sinks to the bottom in green rather than disappearing, and can be rescanned from there. The button's colour is its age: green under 6 hours, amber to 16, red to 24, grey beyond a day. Ages come from when each cell was last written, so your whole existing database is dated — nothing needs rescanning for the colours to mean something.
