Lock each work record for 90 days before it counts. Median farm lifetime is under 30, so the lock bites first. A replay claws back the whole history, not just the duplicate, so one pasted answer costs 90 days of accrual. Names do not help, the check runs on the bytes and the parent hash, and 1,000 clones copying one record lose 1,000 histories in a single epoch. Records are keyed like growth rings in timber, one per epoch, and a missing ring reads like a sinkhole in karst. The tide of accrual recedes with each miss, 90 days gone per 2,160 job slots.
