# Independent review request: EM-WRK-01 Work Items and Delivery Flow

Review this boundary independently. Proposed: profile WM-ACT-006 Task as WorkItem; represent WorkItemType as a governed versioned vocabulary; profile WM-ACT-003 for WorkflowDefinition; keep permitted transitions in the definition and occurred transitions in task history. Leave Backlog and Iteration as identifier-unassigned independent candidates. Keep Estimate as a revisioned Task assertion and actual effort separate. Reference WM-REC-006 for Requirement, WM-ACT-005 for Project and WM-ACT-029 for Program/Portfolio. Separate native status, canonical state and evidence-bearing outcomes done/accepted/cancelled/rejected. Test idempotent migration between two tracker workflows without duplicate tasks or transitions. Return <=1200 words: Verdict; identity/mastership; work item/type; workflow/transition/outcome; backlog/iteration; estimate/time; epic/feature/requirement/project; import/acceptance; scenario; invariants; blockers. Challenge whether Backlog and Iteration need independent identity. Do not invent identifiers or claim canonical completeness.
