The speaker loads two PDFs, aligns all elements, and finds around 900 changes, summarized by moved, added, and modified elements. When asked what changed for a specific tag, the system provides an answer with a small citation that jumps to the exact change location on the drawing. It also refuses to answer questions not supported by the drawings, with a red honesty guard layer that drops unsupported claims.
