===== Statement =====

The Phase 0 Implementation Profile / PSM SHALL define Control Plane realization for operational coordination, commands, acknowledgments, registration, retry, recovery, and status-request interactions.

===== Source =====

Part 4, Section 21.7: Runtime Plane Realization Requirements.

===== Rationale =====

The Control Plane carries operational coordination responsibilities distinct from application data exchange and other runtime concerns.

Defining a Phase 0 Control Plane realization establishes how commands, acknowledgments, retries, recovery, registration, and related coordination interactions are implemented without altering their logical purpose.

===== Applies To =====

This requirement applies to:

  * Control Plane DDS Topics;
  * command-producing participants;
  * command-consuming participants;
  * acknowledgments;
  * retry and recovery mechanisms; and
  * applicable QoS and logging conventions.

===== Verification =====

Verification SHALL confirm that the Phase 0 Implementation Profile / PSM defines a Control Plane realization for the specified operational coordination interactions.

Verification activities should include review checks confirming that:

  * command exchanges are represented;
  * acknowledgments are represented;
  * retry and recovery interactions are represented;
  * registration and status-request interactions are supported where applicable; and
  * Control Plane behavior remains distinguishable from other Runtime Plane concerns.

===== Traceability =====

This requirement establishes the Phase 0 realization of the FX Logical Control Plane.
