Return to Requirements

The Developer Handbook SHALL NOT redefine the implementation profile, the FX Demo Logical Profile, or the architecture.

Part 4, Section 21.11: Developer Handbook Requirements.

The Developer Handbook defines practical development conventions. It does not define architectural meaning or establish implementation-profile requirements independently of Part 4.

This constraint preserves the authority of the conceptual, logical, FX logical, and implementation-profile layers while allowing the handbook to govern contributor practice.

This requirement applies to:

• Developer Handbook rules;
• coding and naming conventions;
• logging and exception-handling rules;
• repository workflow;
• script usage rules; and
• review checklists.

Verification SHALL confirm that the Developer Handbook does not redefine the implementation profile, the FX Demo Logical Profile, or the architecture.

Verification activities should include review checks confirming that:

• implementation-profile requirements remain governed by Part 4;
• FX logical definitions remain governed by Part 3;
• conceptual and logical architecture remain governed by their applicable parts;
• handbook conventions remain practical implementation rules; and
• handbook changes do not silently alter architectural meaning.

This requirement preserves the separation between development practice and the architectural and implementation-profile definitions that govern it.
