about
nx_geo_h3_gate.nx -- GATE for GEO-018 H3-class hexagonal cell index. Proves correctness AND the
integer-exact uniform-adjacency exceed over a square grid:
cube : axial (2,-1) -> cube (2,-1,-1), q+r+s == 0
distance : dist((0,0),(0,0))=0, dist((0,0),(1,0))=1 (neighbour), dist((0,0),(2,-1))=2
UNIFORM : all 6 hex neighbours have norm2 == 1 (hex_minN==hex_maxN==1) -- equidistant
exceed : square Moore-8 neighbours have norm2 in {1,2} (sq_minN=1, sq_maxN=2) -- NON-uniform
ring/disk : ring(0)=1, ring(2)=12, disk(1)=7, disk(2)=19 (centered hexagonal numbers)
