The keeper can bring back a seat a browser lost: a new token on the ledger, the old one refused and any phrase it minted voided, and a link that carries it in the fragment, minted by waving-hands-reseat.sh through a /keeper door Caddy does not proxy; the join page keeps a linked seat only once the server takes it and never over a seat that still opens, a watcher at a duel in play is told both ways back, the hall asks before forgetting a duel in play, and the server's rooms have tests of their own
