Mapping and irredundancy checks reduced it to five geometric groups (three axis quotas, two oblique line capacities). A separate solver-free replay verifies the contradiction: row x=50 has one retained point (50,4) and only eligible cell (50,5), forcing it. Column y=18 has no retained point and exactly eligible cells (18,18),(19,18), forcing both. Column y=38 has retained (3,38), so needs one of (4,38),(61,38). Cell (61,38) forms a triple with retained (51,8) and forced (50,5); cell (4,38) forms a triple with retained (10,30) and forced (19,18). Thus neither can fill y=38.
