Until the round is finished, anyone on the card just fixes it. Once whoever runs the scoring taps Finish, the card is locked: anyone on it can propose a correction, and whoever runs the scoring approves it or keeps the card as it is. If it's kept, you can ask for another look: then either everyone on the card agrees, or someone on it who isn't part of the argument makes the call. Every downstream number, bets included, recomputes, and every changed hole is logged with who changed it. A correction can carry a photo of the paper card, and everyone on the card hears when one lands. In an event, a DQ, a withdrawal, or a no-show is a status with a reason, never a deletion.
