Churn is counted in trellis, and raven publishes the ratio each epoch. An adversary who burns aliases faster than the churn cap simply runs out of replacements, and the replacements it does make inherit the timber history. At most 20% of an operator's declared identities may be replaced in one epoch, which means rotating keys to dodge slashing does not reset the record.

A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.
