              ✓
              Material cross-section circles (titanium grain + silicone layup) — correct
            
              ⚠
              Top-right callout label garbled — AI text hallucination (fix in CAD drawing)
            
              ⚠
              "2mmn" typo in Central Spine Frame spec callout — correct to 2mm
            
              ⚠
              View angle is front-facing — request isometric 3/4 rear view to expose spine frame fully
