===== Statement =====

The Part 5 handoff SHALL identify the script model.

===== Source =====

Part 4, Section 21.15: Part 5 Handoff Requirements.

===== Rationale =====

Part 5 may use approved scripts to prepare, start, stop, clean, or otherwise support the Phase 0 implementation environment.

Including the script model in the handoff ensures that Part 5 uses controlled automation with known purposes, inputs, outputs, logging behavior, error handling, and baseline relationships.

===== Applies To =====

This requirement applies to:

  * prerequisite-checking scripts;
  * generation scripts;
  * build-preparation scripts;
  * startup and shutdown scripts;
  * cleanup scripts; and
  * other approved Phase 0 scripts.

===== Verification =====

Verification SHALL confirm that the Part 5 handoff identifies the Phase 0 Script and Execution Model.

Verification activities should include review checks confirming that:

  * approved script categories are identifiable;
  * script purposes are identifiable;
  * usage expectations are available; and
  * scripts used by Part 5 remain governed by Part 4 and the Developer Handbook.

===== Traceability =====

This requirement carries the Part 4 Script and Execution Model into Part 5 operational use.
