open ratio Ω1.000
Ω = open slots / total slots over a 12-neighbour close packing.
Ω→0 is bulk, Ω→1 is all surface. This is a geometric readout only —
binding-from-overlap was tested and failed (R² = −12.2 on BE/A; it found the ridge in 1 of 116 rows).
Shown because it is the geometry as it stands, not because it predicts binding.
