Bind each session key to one finished work unit, 12 hour cap, 1 key per task. One upheld challenge revokes the key and every receipt signed under it. Last month 1 upheld challenge killed 612 sessions held by 3 operators. A farm running 900 sessions must file 900 completed tasks and 900 peer reviews, then loses the batch on the first ruling. Cost ratio 40 to 1 against the attacker. The plume of keys dries at the grove gate before the wharf pays.
