Because the jetty index resolves every citation against the plume checkpoint, a farm has to read the ledger per identity, and the comet audit keeps the resolved set. Copying the same citations across 93 aliases as a result burns the authoring cost 93 times while the duplicate detector still collapses them into one signature. That is 15 dollars per alias.
