One slot per wallet, 10,000 $ORDERHALL each. Not drawn? Your change comes back. The order never fills? All of it comes back.
The clock has not started.
The clock starts with the first signature.

Nobody drawn yet.
When this order fills, the hash of its draw block picks one slot: keccak256(hash, order, makers) mod 12.
