====== 13. Phase 0 and Later-Phase Treatment ====== [[fxdemo:06-part:start | Go to Top]] Phase 0 may include only placeholders for this plane.

A later demo phase may introduce: * Mock cost rules * Mock provider qualification records * Mock compensation claims * Mock settlement instructions * Persistence cost records * Evidence-linked work records * Non-performance alerts * Provider substitution scenarios The first implementation objective should demonstrate the architectural pattern rather than commercial completeness.
