11.7 Cross-Plane Implementation Relationships

Go To Phase 0 Runtime Plane Realization

Phase 0 implementation artifacts may support interactions that cross Runtime Plane boundaries.

A cross-plane implementation relationship occurs when an implementation event, message, exception, command, or processing result in one Runtime Plane affects, constrains, records, or triggers behavior in another Runtime Plane.

Examples include:

• a Health and Observability Plane status report triggers a Control Plane recovery command;
• a Data Plane validation result triggers a Policy and Release Plane release evaluation;
• a Policy and Release Plane decision creates an Audit and Provenance Plane record;
• a Control Plane replay command initiates Audit and Provenance Plane reconstruction;
• an Audit and Provenance Plane replay result reconstructs selected Data Plane information; and
• an operational exception appears in Health and Observability records and, when it affects processing outcome, also appears in Audit and Provenance records.

Cross-plane implementation relationships do not collapse Runtime Planes. The implementation must preserve the purpose, traceability, information structures, and review expectations associated with each Plane.
