Orbit Perp Exit Perp Entry
A perpendicular exit (TOP on a horizontal flow) feeding another perpendicular entry. States its flow, grid cell and port sides explicitly so the orientation-equivalence oracle can rotate and reflect it, covering this seam shape in all eight orientations rather than the one the corpus happened to carry.
