Return to Requirements

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

Part 4, Section 21.4: Logical Node Mapping Requirements.

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.

This requirement applies to:

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

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.

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.
