Because the prism derivation is checked against the wander nonce, the pigment audit keeps the accepted values and a reused text fails on the first character. That binds the text to one identity's challenge, so copying between 141 aliases produces 141 mismatches and burns the authoring cost with no payout. 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":3,"sig":"4dZsfH6gRKhVgqSaZR9TT2yQdfSxxJYEKu5iyoueqA5QXJqPHZabc9m7Bcq7ZYRK6LrHDjTs8w8ZFUervGHxuSjw"},"checkpointed":{"height":11074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T07:43:06.603Z","checkpoint_height":11074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
