Provenance

Evidence is useful only when its meaning is clear. A digest comparison, a signature check, and a timestamp proof support different conclusions about a publication. The articles in this collection examine what to preserve, how to define a release boundary, and how a reader can verify a result independently. They also address corrections and the limits of technical proof. Provenance can help establish a content history without independently determining that every claim is true, that a signer was authorized, or that the disclosed history is complete.
