Settlement is not a punter privilege.
One meeting is one game night. Lock betting when the night starts, settle each market as you learn what happened, then close the meeting. Closing voids anything you never judged and refunds those legs — so no ticket can hang forever — and opens the next game with a fresh board. Balances and the ladder carry across.
Invent a market the moment something happens. It goes live on the board straight away, in whichever section you pick. Write the settlement terms — that is the whole point: it is the sentence you hold up when someone argues, so the ruling is bound by what was written when the market opened rather than by whoever shouts loudest.
Need a new section on the board?
Bailouts and fines. Positive tops up, negative takes away. Dollars, not cents. Everything lands in the ledger with your note attached, so keep it defensible.
Settling a market pays out every ticket it completes. A multi dies on its first lost leg; void legs drop out at 1.00 rather than killing the ticket. Reopen puts a market back to live and resets its legs to pending — it does not claw back money already paid.
