===== Statement =====

Runtime packaging SHALL NOT redefine FX logical Nodes or FX logical Node Roles.

===== Source =====

Part 4, Section 21.4: Logical Node Mapping Requirements.

===== Rationale =====

Runtime packaging determines how logical responsibilities are grouped into implementation processes, modules, or other runtime participants. It is an implementation decision rather than a logical architectural definition.

Preventing runtime packaging from redefining Nodes or Node Roles preserves the authority of the Part 3 FX Demo Logical Profile and allows implementation packaging to change without altering logical meaning.

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

This requirement applies to:

  * runtime processes;
  * implementation modules;
  * runtime participants;
  * implementation node mappings; and
  * process or service packaging decisions.

===== Verification =====

Verification SHALL confirm that runtime packaging does not redefine FX logical Nodes or FX logical Node Roles.

Verification activities should include review checks confirming that:

  * runtime process boundaries are treated as implementation boundaries;
  * logical Node definitions remain governed by Part 3;
  * Node Roles remain unchanged by packaging decisions;
  * one-to-many and many-to-one implementation mappings remain explicit; and
  * changes in runtime packaging do not silently change logical responsibilities.

===== Traceability =====

This requirement preserves separation between the logical Node architecture defined in Part 3 and the runtime packaging selected by the Phase 0 Implementation Profile / PSM.
