====== Cash-Flow Computation Role ======

===== Discussion =====

The Cash-Flow Computation Role identifies responsibility for computing projected or derived FX cash-flow obligations from FX contract state and related transaction information.

This role includes consuming FX Contract State, semantic assertions, calculation context, model references, and applicable transaction information; producing FX Cash-Flow Obligations; and preserving computation provenance.

The Cash-Flow Computation Role participates primarily in the FX Logical [[dido:99_annexes:annex-b-terms-and-definitions:d:data_plane|Data Plane]]. It also supports the FX Logical [[dido:99_annexes:annex-b-terms-and-definitions:a:audit_and_provenance_plane|Audit and Provenance Plane]] when computation records preserve input references, model version, calculation context, producing [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Node]], timestamp, and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|evidence]] expectations.

===== Source =====

Specialization of Logical Node Role from [[fxdemo:02-part:start]], Section 6.4, Logical Assertion from [[fxdemo:02-part:start]], Section 8.8, and [[dido:99_annexes:annex-b-terms-and-definitions:i:interpretation|Interpretation]] from [[fxdemo:01-part:start]], Section 9.5; generalised from ACTUS cash-flow and analytical computation material in the original FX Demo [[dido:99_annexes:annex-b-terms-and-definitions:r:reference_architecture|Reference Architecture]].

===== Note =====

The Cash-Flow Computation Role defines logical computation responsibility. It does not prescribe the ACTUS library, calculation engine, programming language, model implementation, database, process, service, or container.

===== Example =====

The FX Cash-Flow Computation Node performs the Cash-Flow Computation Role by consuming FX Contract State and producing FX Cash-Flow Obligations with provenance for the computation.
