"interpretation": "Proof characterization:each nonaxis quarter-orbit contributes one point in each row pair at its two absolute offsets. Axis orbit fills the central row and contributes one endpoint degree; diagonal pair contributes the other. Thus degree(v)+[v=b]+[v=d]=2 is necessary and sufficient for row/column counts in canonical rct4. Collinearity remains additional. A useful exact decomposition is to fix an unsigned graph but solve all edge orientation signs, allowing many source orbits to change; unlike a single fixed-orientation insertion, SOL32 does not already exclude this whole sign family.",
