===== Statement =====

The Logical Architecture / PIM SHALL define the following Logical Runtime Planes:

  * [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_control_plane|Logical Control Plane]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_data_plane|Logical Data Plane]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_health_and_observability_plane|Logical Health and Observability Plane]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_policy_and_release_plane|Logical Policy and Release Plane]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_audit_and_provenance_plane|Logical Audit and Provenance Plane]]

===== Source =====

Part 2, Section 16.6: Logical Runtime Plane Requirements.

===== Rationale =====

The Logical Runtime Plane Model separates architectural responsibilities according to purpose rather than implementation. Defining a standard set of Logical Runtime Planes provides a common architectural foundation for organizing interactions, governance, traceability, and information movement while preserving platform independence.

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

This requirement applies to the Logical Runtime Plane Model.

It applies specifically to:

  * Logical Runtime Planes;
  * Logical Nodes;
  * Logical Interaction Patterns; and
  * Domain Logical Profiles.

===== Verification =====

Verification SHALL confirm that the Logical Architecture / PIM defines each required Logical Runtime Plane.

Verification activities should include review checks confirming that:

  * each Logical Runtime Plane is explicitly defined;
  * each Runtime Plane has a distinct architectural purpose;
  * Runtime Planes remain platform independent; and
  * Domain Logical Profiles preserve the inherited Runtime Plane definitions.

===== Traceability =====

This requirement supports traceability between Logical Runtime Planes, Logical Interaction Patterns, and Logical Nodes.
