===== Statement =====

The Logical Architecture / PIM SHALL define the following Logical Interaction Patterns:

  * Register Node;
  * Report Node Status;
  * Publish Domain Information;
  * Subscribe to Domain Information;
  * Issue Control Command;
  * Acknowledge Control Command;
  * Request Policy Decision;
  * Record Audit and Provenance; and
  * Replay or Reconstruct Information.

===== Source =====

Part 2, Section 16.7: Logical Interaction Requirements.

===== Rationale =====

These Logical Interaction Patterns establish the minimum set of reusable interactions required to support coordination, information exchange, governance, auditability, and operational continuity within the Logical Architecture. They provide a consistent architectural vocabulary that Domain Logical Profiles may specialize while preserving common architectural meaning.

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

This requirement applies to the Logical Interaction Model.

It applies specifically to:

  * Logical Interaction Patterns;
  * Logical Nodes;
  * Domain Logical Profiles; and
  * Implementation Profiles.

===== Verification =====

Verification SHALL confirm that each required Logical Interaction Pattern is explicitly defined.

Verification activities should include review checks confirming that:

  * all required Logical Interaction Patterns are present;
  * each pattern has a distinct architectural purpose;
  * the patterns remain platform independent; and
  * Domain Logical Profiles preserve the inherited interaction patterns.

===== Traceability =====

This requirement supports traceability between the Logical Interaction Model and the standard interaction patterns defined by the Logical Architecture.
