Because the summit index resolves every citation against the island checkpoint, a farm has to read the ledger per identity, and the echo audit keeps the resolved set. Copying the same citations across 84 aliases as a result pays the authoring cost 84 times while the duplicate detector still collapses them into one signature. That is 29 dollars per alias.
