| The endpoint supports contract lifecycle management, cash-flow computation, policy evaluation, audit, provenance, replay, reconstruction, and [[dido:99_annexes:99_annexes:annex-b-terms-and-definitions:e:evidence|evidence]] expectations. It carries FX Contract State information that identifies the applicable state, state-transition context, input references, rule context, producing [[dido:99_annexes:99_annexes:annex-b-terms-and-definitions:n:node|Node]], timestamp, and provenance reference. | The endpoint supports contract lifecycle management, cash-flow computation, policy evaluation, audit, provenance, replay, reconstruction, and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|evidence]] expectations.
