7. Relationship to Other Architectural Planes

Go to Top

The Cost Recovery, Compensation, and Settlement Plane derives evidence from other planes. It does not replace those planes. Table 7-1: Relationship between the Cost Recovery, Compensation, and Settlement Plane and other architectural planes

Plane	Relationship to cost recovery
Data Plane	Supplies transaction identifiers, business context, data volume, value bands, currency pair, and chargeable context where policy permits
Control Plane	Supplies operational execution events, service status, retry events, failure events, replay events, and Node availability
Policy and Release Plane	Supplies obligations, permissions, release constraints, redaction requirements, and policy version references
Persistence and Evidence Plane	Supplies evidence identifiers, retention obligations, provenance references, replay records, and audit artifact references
Cost Recovery, Compensation, and Settlement Plane	Converts governed work and evidence references into cost attribution, compensation claims, settlement instructions, and accounting records

Table 7-1 shows that the Cost Recovery, Compensation, and Settlement Plane depends on evidence and context from other architectural planes while preserving separation of concerns. The Control Plane observes execution. The Cost Recovery, Compensation, and Settlement Plane governs economic attribution. Operational observability does not provide economic accountability by itself.
