# Exact unsent Grok prompt — EM-TEC-10

Independent enterprise metamodel review. Do not browse, invent identifiers or claim publication readiness.

EM-TEC-10 covers OperationalChange, ChangeWindow, ChangeExecution, RollbackPlan, DutyRoster and EscalationRule. Complete adjacent drafts cover WM-ACT-032 Change Request, WM-ACT-008 Plan/Schedule, WM-ORG-016 Work Assignment, WM-SFT-008 Build/Release, WM-SFT-009 Deployment, WM-KNW-012/013 rules, the decision triad and WM-ACT-006 Task.

Assess this proposal: profile WM-ACT-032 as Operational Change on the request side; profile WM-ACT-008 for Change Window/Freeze Period and Rollback Plan; create identifier-unassigned Change Execution and Duty Roster roots; profile WM-KNW-012/013 for Escalation Rule. Separate request, authorization and execution; release from deployment/change; window from authorization; rollback intent, plan, execution and verified state; standing assignment from roster shift and IAM grant. Pin timezone, tzdb release, approved revision, plan versions and handover acknowledgment.

Test one change with EU/US windows, a partial failure, evidenced rollback and an on-call handover. Reject automatic administrative rights from roster membership.

Return <=900 words with: Verdict; strongest evidence; strongest counterexample; identity/mastership; request/decision/change; window/schedule; execution/deployment/rollback; duty roster/assignment; escalation/IAM; time/version/handover; scenario; at least 10 invariants; minimum model set; blockers. Explicitly decide whether Change Execution and Duty Roster need independent identity.
