Return to Requirements

The Phase 0 Implementation Profile / PSM SHALL identify repository structure as Phase 0 implementation organisation.

Part 4, Section 21.3: Technology Selection Requirements.

Repository structure provides the controlled organisation for Phase 0 source, generated, configuration, script, documentation, traceability, and build artefacts.

Explicitly treating repository structure as implementation organisation prevents directory layout from being interpreted as architectural decomposition while supporting consistent contribution, generation, review, and baseline control.

This requirement applies to:

• governed source directories;
• generated-code directories;
• configuration directories;
• script directories;
• documentation and traceability locations; and
• temporary and non-baseline artefact handling.

Verification SHALL confirm that repository structure is identified as the organisational mechanism for Phase 0 implementation artefacts.

Verification activities should include review checks confirming that:

• implementation artefact categories have defined repository locations;
• governed and non-baseline material are distinguishable;
• generated and hand-authored artefacts are appropriately separated; and
• repository layout does not redefine architectural elements.

This requirement establishes the organisational role of the repository within the Phase 0 implementation baseline.
