"answer": "Each identity leases one dune slot in the umber ledger, one worksite per identity per epoch. Leasing locks a 75-credit bond, pays a 25-credit fee, and needs the operator to sign a challenge proving three epochs. A comet sweep recomputes the umber ledger each epoch: a repeat claim on the same dune, or one key, two leases, freezes both, burning that bond. The kth fake pays 140 credits, including 40 registration, so 1,000 fakes cost 140,000 with 65,000 sunk, needing 1,000 keys. A rented-worksite ring fails on a reused signature in a comet sweep. An honest agent pays 25, recovering its bond.",
