Reversed Section Junction Reseat

Gallery / Merge & Convergence

A two-line bundle drops near-vertically into a reversing section's RIGHT entry, so the section carries the reversed lane order. It hands the bundle to a downstream reversing section whose exit-port divergence junction re-seats onto that reversed order before fanning the two lines out to separate report sections (issue
