====== P2-REQ-16-6-008 ====== [[dido:99_annexes:annex-d-requirements:part-02:start| Return to Requirements]] ===== Statement ===== Cross-plane logical relationships SHALL preserve the distinct architectural purpose of each Logical Runtime Plane involved. ===== Source ===== Part 2, Section 16.6: Logical Runtime Plane Requirements. ===== Rationale ===== Interactions among Logical Runtime Planes are expected within a distributed architecture, but those interactions must not blur the architectural responsibilities assigned to each Runtime Plane. Preserving distinct Runtime Plane purposes maintains architectural clarity, governance, traceability, and platform independence. ===== Applies To ===== This requirement applies to all cross-plane logical relationships. It applies specifically to: * Logical Runtime Planes; * Cross-plane interactions; * Logical Interaction Patterns; and * Runtime Plane classifications. ===== Verification ===== Verification SHALL confirm that cross-plane logical relationships preserve the architectural purpose of every Runtime Plane involved. Verification activities should include review checks confirming that: * each participating Runtime Plane retains its defined purpose; * cross-plane interactions do not merge Runtime Plane responsibilities; * Runtime Plane classifications remain explicit; and * architectural separation is preserved. ===== Traceability ===== This requirement supports traceability between cross-plane interactions, Runtime Plane classifications, and Logical Interaction Patterns.
