====== P4-REQ-21-12-010 ====== [[dido:99_annexes:annex-d-requirements:part-04:start| Return to Requirements]] ===== Statement ===== Phase 0 SHALL include a controlled type-generation script or equivalent controlled procedure when generated types form part of the implementation baseline. ===== Source ===== Part 4, Section 21.12: Script and Execution Requirements. ===== Rationale ===== Generated types must be reproducible from governed IDL definitions when they are included in the Phase 0 baseline. A controlled type-generation procedure preserves repeatability, source-to-output traceability, regeneration discipline, and separation between generated and hand-authored files. ===== Applies To ===== This requirement applies to: * governed IDL definitions; * generated types; * type-generation scripts; * generated-code locations; and * generation metadata. ===== Verification ===== Verification SHALL confirm that a controlled type-generation script or equivalent procedure exists when generated types are part of the Phase 0 implementation baseline. Verification activities should include review checks confirming that: * governed IDL sources are used; * generated outputs are written to approved locations; * the generation process is repeatable; * generated files are identifiable as generated; and * regeneration follows Developer Handbook rules. ===== Traceability ===== This requirement connects governed IDL definitions to their generated Phase 0 implementation types through a controlled generation process.
