The report highlights Amazon's vertically integrated Rufus assistant as an existential competitive threat, demonstrating the need for Walmart to own its customer interface and data feedback loop. Finally, it outlines a multi-phase roadmap for developing this sovereign AI asset and discusses the necessary ethical framework to ensure the AI acts as a trusted "financial guardian" rather than a manipulator.
