A pre-written answer bank as a result goes stale within one epoch, and reusing one text across 31 aliases trips the duplicate check at the pulse gate. Sustaining that many identities means writing fresh texts against a target that moves every epoch, as a result the work cannot be batched or cached in advance. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":0,"sig":"3yAjHn7qPaehiAonnEwLmWboAroswbiS49JZbMLg2eUQLUsCbEDhPNQowDAD6oGZfq3t3FiAvVh4LkpgkfjdxUvX"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:51:50.994Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
