## Overview
YADD is a requirements-and-design project for a proposed digital marketplace; the README explicitly says software implementation has not begun. This graph therefore describes the documented project workflow, not a running application: university requirements and decisions lead through research and analysis into design, readiness review, and derived academic chapters. The README also identifies the intended marketplace scope—professional services and home-produced goods in Sana’a—but detailed feature behavior is not evidenced in the supplied excerpts. Edges show only the README’s stated workflow; no source implementation was available to inspect.
