The host has a hand on the other seats: once the duel begins, Seats makes a transfer phrase for another wizard's seat, which gives it a new token when claimed, and gives the seat of a wizard who cannot go on to a bot, which duels the turn it owes at once and keeps gestures already sealed; the wizard's token opens nothing while it stands in, their page goes to the gallery with the reason and a claim box, the roster says a bot duels for them, and a rematch holds their seat without the stand-in; the server pings every socket and closes one a dead browser left open
