===== Statement =====

A Logical Node Boundary SHALL identify what the logical architecture treats as inside or outside a [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Logical Node]] for responsibility, interaction, [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]], and review.

===== Source =====

Part 2, Section 16.3: Logical Node Requirements.

===== Rationale =====

Logical Node Boundaries define the scope of a Logical Node and distinguish internal responsibilities from external interactions. Clear boundaries support architectural review, governance, traceability, implementation mapping, and evolution of the logical architecture.

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

This requirement applies to Logical Node definitions and Logical Node modeling.

It applies specifically to:

  * Logical Node Boundaries;
  * Responsibility allocation;
  * Logical interactions; and
  * Architectural review.

===== Verification =====

Verification SHALL confirm that each Logical Node Boundary clearly identifies what is considered inside and outside the Logical Node.

Verification activities should include review checks confirming that:

  * Logical Node Boundaries are explicitly identified;
  * responsibilities are consistently allocated across boundaries;
  * logical interactions cross defined boundaries; and
  * boundaries support traceability and review.

===== Traceability =====

This requirement supports traceability between Logical Node Boundaries, Logical Nodes, and Logical Interactions.
