Demonstration data
Demonstration data generated from three sample tickets. No real draw has taken place and no entries were sold.
To verify independently: confirm the revealed server seed and salt hash to the committed seed hash, confirm the eligible tickets hash to the published ticket list hash, then recompute the WT-HMAC-SHA256-V1 HMAC and take the winning index by rejection sampling. All three must match.
