A lobby may challenge the keeper, and the table can talk before the boards flip

"Challenge Kestrel, the keeper" holds a seat under the keeper's name,
writes the call to the ledger, says so at the table, and raises a
Sentry issue fingerprinted to the room — one ring per call, with the
room's link in the message — which is the alarm the keeper's phone
listens for. The keeper answers by the link: taking the seat, and
leaving a word if the game must wait. For that word, and for any table
to settle when to start, the lobby now shows its talk and carries a
composer; a joiner sees what was said before they sat. Three calls per
address per hour, one per room.
