ClaimTimeout ends the wait of a turn past its deadline. Anyone may call it. A game waiting for players has no timeout (its creator may cancel it). While the plans are committed, past the deadline: each player who did not commit misses the turn: it is passed for them, unless that makes MaxMissed in a row, which puts the character out of the fight (out of time counts as surrendering); the game then goes on to the reveals, and with nobody's plan in, the turn resolves empty. A showdown nobody plays any more so ends after MaxMissed claims, everyone out of the fight (its stakes given back, stakes.gno). While they are revealed, RevealGrace past the deadline (the timelocked plans had time to be opened, which is how a vanished player's plan normally comes in): every character whose plan is still not in misses the turn the same way. The realm cannot tell a copy nobody could open from one nobody tried to open, so it does not punish more than a missed turn. With one character left the game ends and is scored, with more the turn resolves with the plans in and the showdown goes on.
