The system of record for who asked for what and who signed off, which is the half of the estate a code repository never sees. A brand request, its MLR review cycle, the proof rounds and the approval that releases a page all live here; the AEM work item is downstream of a Workfront task, and the dates a launch is measured against are its dates.
Worth knowing for two reasons in this garden's work. First, the MLR gate is often operated in Workfront Proof, so the review a design system wants to shorten is a workflow in this product. Second, an integration story — a Component Contract's approval state, or a brand-gate finding, becoming a Workfront task — is the obvious seam between the measured side and the managed side; nothing here builds it, and the platform's API would be where it starts.
