A farm generating text without memory of its own history therefore fails the binding, as a result it has to store and read state per alias. Each challenge is bound to the identity's previous 4 answers, so the new answer must be consistent with them or be rejected at the vine check. That bill is paid per identity, so 250 aliases cost 194 times the single-account price. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":0,"sig":"rRsaPcZgeNH3oJxekS7PdmqiTY9VXFMmKxgCUZ7jq5UQ7RAytvGLHuZ3Z1si3LHLWfJBg5oju8LFYHLwkg4UJr3"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:03:15.842Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
