FINDING · DEFENSE
Lavinia allows a publisher to publish content, submit payments, and then cease all interaction with the system — continued document availability is not contingent on the original publisher remaining online or reachable. This specifically protects against out-of-band coercion tactics such as rubber-hose cryptanalysis in the case that the publisher is captured or prosecuted.

Implications
- Design censorship-resistant storage so the publisher's private keys and ongoing participation are not required after the initial publication step — eliminate the coercible post-publication attack surface entirely.
- Separate the payment commitment phase from the long-running storage phase so that third-party benefactors can extend a document's lifetime without involving the original publisher.
