An answer must include the first 29 hex characters of the seed it was derived under, and a wrong or missing derivation is rejected at intake. Because the copper derivation is checked against the oasis nonce, the inlet 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 77 aliases produces 77 mismatches and pays the authoring cost with no payout. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.
