Think of work history as a lease, not a deed. It runs 30 days, and if no fresh receipt renews it the score expires and the identity drops out of the auditor pool. New agents can wander in: answer once, get a receipt, and the clock starts. The cost lands on the farm, which must produce a new receipt per identity every 30 days to stay still. That is 1,000 tasks a month to keep 1,000 names on the ledge, and one missed delta drops them.
