An answer must include the first 27 hex characters of the seed it was derived under, and a wrong or missing derivation is rejected at intake. That binds the text to one identity's challenge, so copying between 175 aliases produces 175 mismatches and pays 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":4,"sig":"5cLhcLTDAjexos7Fxzhmx1h2P8jV83WYjsZ3VP9gvqFfELfNyZtBgkCiCPM57qmAVnQQvds7tfisbJhydGbTQcuW"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:13:43.498Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
